TEST: RCF Ayra Pro 8

 As with almost all other instrument groups, the area of ​​near-field monitors has exploded in terms of supply in recent years. More and more suppliers with more and more product lines are trying to find their place in the huge pool of top dogs, trendsetters and flash grenades. Unfortunately, there are only comparatively few criteria for getting buyers to listen to you. In addition to interesting detailed solutions or extravagant finishes, it is above all the price that can attract attention in the hobby and amateur sector. The traditional Italian company RCF, founded in 1949, probably thought the same thing and brought a near-field monitor onto the market with the RCF Ayra Pro8, which tries to attract buyers with a very affordable retail price of 223 euros and quite mature features.

The construction of the RCF Ayra Pro8

The RCF Ayra Pro8 is an active 2-way near-field monitor, which is quite generous with its dimensions (H x W x D): 410 mm x 253 mm x 320 mm, but quite moderate with a weight of just under 9 kilograms. According to the manufacturer, the system offers a frequency response of 45 Hz to 20,000 Hz, which is transmitted by an 8-inch fiberglass composite woofer and a 1-inch neodymium driver. The woofer receives 100 watts, the tweeter 40 watts, both from separate Class D amplifiers. The maximum level (@1m) is specified as 111 dB. The crossover frequency is 2 kHz, where you can also see a small dip in the frequency spectrum.

The housing is made of the usual MDF panels, is neatly coated with a fine textured varnish and is otherwise impeccably finished. Current hype such as excessively rounded corners to minimize reflections is nowhere to be found in this box. The box stands on its regular housing; adhesive feet or mats for decoupling the housing are not included. The monitors have definitely exceeded their area of ​​application on a desk with their dimensions and require appropriate speaker stands. Although these are often supplied with an appropriate rubber or foam pad, I would recommend a cheap item such as 4 adhesive rubber feet as an accessory.

The front

The two speakers are mounted on the front in a metal frame that has been seamlessly adapted to the housing. Four solid Allen screws each hold the woofer and the tweeter horn, which enables a radiation angle of 110° x 70°. I don't think I've ever seen such a large waveguide on a near-field monitor in my career, the dimensions of which even extend into the area of ​​the woofer and therefore have to be cut into something.

According to a product video, RCF is particularly proud of the 0 degree phase response, which is only possible due to the specially developed DSPs of the AYRA studio monitors in combination with the exclusive RCF FiRPHASE and, according to the company, is unique in this price range. Below the woofer there are 2 bass reflex openings which emit their signal to the front. Personally, I always prefer the reflex opening in the front area of ​​the box with 8 inch woofers, as this makes it easier to control the bass regardless of the room structure.

What is noticeable is the comparatively hard suspension of the woofer. Although the surround works very softly and loosely, the woofer is designed especially for strong impulses, which should be particularly noticeable at higher volumes.

The back

In terms of connection peripherals, RCF offers the complete package for the consumer sector. In addition to the symmetrical standards XLR (unfortunately not lockable) and TRS, the RCF Ayra Pro8 also offers the RCA standard, which is still very popular in the hobby sector. A volume control offers a -6 dB setting at 12 o'clock, 0 dB when fully clockwise, and complete silence when fully counterclockwise. The 12 o'clock setting makes it much easier to adjust the volume between the speakers, although only the 12 o'clock and full load ranges are easy to find, which is the main area of ​​use in this performance class.

In terms of room adaptation, the speaker is quite spartan, although adequate. The bass range can be raised or lowered by 2 dB using a slider, and the same applies to the treble range by 1 dB each. The final part is a power connector socket with an on/off switch.

In practice

When you switch on the speakers, a small white LED bar indicates that the system is ready for use. The system runs consistently; the RCF Ayra Pro8 does not offer a standby function. As always, the monitor has to face a mixture of reference recordings, measurement tones and finished productions, which I have supervised and created myself.

When you start using the monitors, you notice the initially very moderate bass range, which you would have expected to be much more powerful based on the visual appearance. The range is present, but seems a bit flat, especially in the low mids. Activating the bass boost changes this a little, but makes the overall sound a bit "boomy", after which I deactivate the boost again. The bass lift seemed a bit too uneven to me personally, which led to an over-presence in some electric bass passages, for example. Overall, the bass range sounds a bit flat. The frequencies are there, but the necessary, soft "feel-good feeling" does not appear.

The midrange is fine, apart from the dip at 2 kHz. Distorted guitars in particular have a peak here, which makes them seem comparatively tame on the RCF Ayra Pro8. This means that there is a risk that you will quickly set the guitars too harshly in order to give the instruments more bite. This aspect should always be kept in mind, especially during the mixdown. The vocals also lose a little of their presence, which also needs to be taken into account.

The treble range, like the bass range, is very reserved. Not that the range seems musty or even pale, but I miss the "fine" in the highs, the "whisper" that gives a recording its shine and justifies the extra euro when buying high-quality preamps, for example for vocal recordings. While it is certainly sufficient for a live speaker, I set the bar a little higher in the studio area. This point can be improved somewhat by increasing the treble, but ultimately it has to give way to the retail price.

What really proves itself in practice, however, is the phase position of the RCF Ayra Pro8. The Italians have actually managed to establish a very homogeneous coordination between tweeters and woofers, so that there is no cancellation on the way to the human ear. The depth gradation is fine, although the spatial image corresponds to a good minimum. In general, I cannot help but get the impression that the speakers reproduce comparatively little of the space in the recording. It is well known that a lot of spatial information is lost in today's limiter 0dB jittery mastering, so this impression is not unusual. However, one does get the impression that even with unmastered recordings the room ends comparatively just behind the speakers, which is noticeable in direct comparison to other systems.

What is also very striking is the volume at which the monitors develop their maximum quality. The speakers gain in sound quality as the volume increases. The RCF Ayra Pro8 actually has its best sound just before the human ear reaches saturation, although I personally think it's much too loud for a normal working environment. A decent room volume is not the system's strength. You can actually hear how the character of the system decreases when the volume is reduced. The extent to which this affects personal listening habits is another question.

The system's impulse fidelity is also impressive, especially at higher volumes. Despite the moderate power specifications, the system has enough headroom to cleanly transmit even powerful kick signals or other power-hungry impulses.

All in all, however, the RCF Ayra Pro8 has to be acknowledged as having a really good price/performance ratio. For a retail price for which you wouldn't even get the woofer on its own from another manufacturer, you get a complete system that covers the entire frequency range.

Conclusion

With the RCF Ayra Pro8, the Italian manufacturer has a near-field monitor in its range that offers a lot of listening for comparatively little money. The system offers comprehensive frequency coverage, very good phase position and good impulse fidelity even at high volumes.

On the other hand, if you can live with average spatial resolution and a subtly flat basic sound, you should definitely try out the system.

TEST: RCF 932-A

 Italy, the second. This is how, or something similar, you could actually start this review if you look at the current product range of the Italian manufacturer RCF, as far as active full-range speakers are concerned. With the RCF ART 932-A, the traditional company is preparing to make its mark in the already highly competitive area up to approx. 2 KW peak. Let's see how "Forza Italia" fares with this product from the area of ​​active full-range speakers.

Structure and concept of the RCF ART 932-A

As with its little sister, the RCF HD 10-A MK5, if you look closely you will notice the production location of the product. In contrast to the now almost all-encompassing supply chain, "Developed in home country, assembled in China", a proud "Made in Italy" lettering is also emblazoned on the housing. How much the entire world is now dependent on the Asian world power can once again be seen very clearly in the partially empty shelves in various industries. Even if some of the components inside the RCF ART 932-A come from China, there should be fewer problems with this product, at least when it comes to delivery from the factory to the customer.

The RCF ART 932-A takes no risks when it comes to application and, like many of its competitors, tries to cover several sound options thanks to its asymmetrical housing shape, which increases the product's application area immensely. The possible applications range from small PA to sidefill to typical wedge operation, although with the latter you should be aware that the stability is significantly lower than with a pure wedge. Be warned against the typical "big pants foot on wedge" - there are few actions that look more ridiculous on stage than slipping on a floor monitor during a big pose. The system also has M10 thread inserts on the top and bottom, or side panels of the housing, for flown fixed installations. The box has a robust 36 mm steel flange on the bottom for use with a stand.

With dimensions (H x W x D): 642 mm x 370 mm x 363 mm, the box is in the middle segment in terms of transportability and, with its weight of 18.8 kg, can still be easily carried by a single person. The housing of the RCF ART 932-A is made of polypropylene, which, with a combination of comparatively low weight and good elasticity, should absorb both internal vibrations and rougher external influences well. For better protection, you can also purchase an appropriate protective cover, which I personally can only recommend if the visual appearance of your equipment is important to you. Scratched boxes always leave a bad taste in your mouth when it comes to paying after the show.

Two grip slots on the top/bottom of the housing and two generous grip recesses on the sides ensure good handling and easy transport, which not only increase carrying comfort, but also make it much easier to balance on a high stand.

The loudspeaker equipment consists of a 12" woofer made in-house and a 1.4" tweeter, which together can deliver 1050 watts peak, i.e. around 500 watts sine, and for those who love numbers, boast 2100 watts peak. The frequency response of the system is specified as 50 Hz - 20000 Hz, the sound pressure is 132 dB (Max SPL @ 1m), the horizontal radiation angle is 100°, the vertical radiation angle is 60°. The crossover frequency is 700 Hz, which is relatively low due to the comparatively large tweeter. As a special feature, the manufacturer also refers to the new filter technology called "Firphase" in this version, which, according to the company brochure, ensures "a transparent sound, absolute clarity and a perfect stereo image with minimal latency without phase distortion".

The back

As with many other representatives of this type, all connections are on the back of the housing, although RCF has also reduced the operating options to a minimum and transferred the entire sound signal management to a mixer connected in front of it. The advantage of a spartan equipment is always that even inexperienced users cannot cause major damage in the event of a mismatch. The disadvantage, however, is that experienced users have to make almost all frequency-related settings via an external console, which offers significantly more sound options, but also requires a minimum level of technical know-how.

All controls are installed very deep in the housing and are therefore very well protected from external influences, provided they are in flat contact with the panel. In contrast to its little sister, the only control present, the master volume control, sits comparatively firmly in its socket despite the lack of a counter on the housing, which offers a much better feel.

An XLR / TRS combo input socket, combined with the aforementioned volume control, serve the user as input management. In addition, a push button enables a rough pre-selection of the applied signal level, consisting of the presets "Linear", "Boost" and "Stage", the respective activation of which can be read off via 2 green LEDs. Unfortunately, there is no gain control, so you should keep an eye on the overload displays in the master area when outputting the signal via the mixer. The system also offers an XLR out for daisy chain operation. The system status can also be read off via 2 LEDs (signal - green and limiter - red).

Finally, in the lower part of the housing below the cooling fins of the system, there is the on/off switch plus the cold device socket and the internally installed main fuse. The system does not have a multi-voltage power supply and is approved for either 220 - 240 volts or 100 - 120 volts mains voltage. The values ​​of the fine fuses used behave accordingly differently.

The RCF ART 932-A in practice

Like other active speakers before it, the RCF ART 932-A was subjected to my standard test routine for flexible full-range speakers, i.e. operation as a floor monitor in the studio, high-stand operation indoors and high-stand operation outdoors up to a distance of 50 meters. Even from the first notes, it is noticeable that the system provides a very high sound pressure for a 12-inch woofer combination. The speaker sounds very powerful, but this is also due to the fact that the speaker leaves a lot to be desired in the real deep bass range and specializes more in very good low-mid reproduction. I would therefore still use an additional subwoofer for real "physicality" in bass reproduction.

What is particularly noticeable, however, is the comparatively very high level that the RCF ART 932-A can generate when required. The aforementioned 500 watts sine offer a very strong assertiveness, especially in a closed room, especially since the onset of saturation or the activation of the protective devices are protected with a very high headroom. In the open field, the sound naturally spreads out much more, but you still get a good definition of the signal and good intelligibility in the direct radiation angle, which at 100 degrees horizontally is somewhat wider than average.

As already mentioned, the RCF ART 932-A is designed for operation with a corresponding mixer, which controls the system's catch-up amplifier accordingly in terms of level. You can connect a microphone or an external device directly to the system, but in this case you will lose a lot of performance, as this is a clear mismatch. Most users will probably set the volume control to the right and generate the final volume with the master controls on the console. If the volume is limited accordingly, for example within a fixed installation, you can turn the master down accordingly.

In terms of sound, the system impresses with very stable playback, which is tonally very balanced without any unpleasant peaks until shortly before the limiter is activated. Overall, the system has to be given a very good rating, including a high level of flexibility in terms of its area of ​​application, especially in relation to its reasonable price despite being manufactured in Europe.

Conclusion

With the RCF ART 932-A, the Italian manufacturer has a very good-sounding full-range speaker with very stable headroom in its range. The system is very flexible in terms of its use due to its trapezoidal shape and impresses with a neutral basic sound, which offers a very high level including decent sound pressure when required. If you are looking for a powerful, powerful and very good sounding speaker and the use of an external console is part of your workflow anyway, you should definitely try out this speaker.

TEST: RCF ART 915-A

 The ART series from RCF has made a very good impression on me so far, especially since the active full-range speakers delivered a very "mature" sound in relation to their dimensions, which was in some cases significantly higher than what one would normally expect in this performance and size class. The third representative of the ART series, the RCF ART 915-A, is the battleship of the series, which for the first time is also a category higher than its competitors in terms of dimensions.

Structure and concept of the RCF ART 915-A

The first thing that strikes you in direct comparison with the smaller 932-A is the lower price! Bigger speaker, lower price, how can that be, many people will probably ask themselves. The question is put into perspective when you look at the price of the 912-A, which is actually priced below the 915-A. So what makes 3 instead of 1 so extraordinary?

The difference can be seen in the loudspeaker configuration, with the tweeter in combination with the crossover frequency playing a special role. While the 93 series has a 3 inch neodymium compression driver with a crossover frequency of 800 Hz, a comparatively low crossover, the 91 series works with a traditional 1.75 compression driver that separates at 1800 Hz. In return, this means that the woofer is better supported in the midrange reproduction and the typical midrange hole that often appears in the classic 15/1 combination is much less common in this combination. Furthermore, the neodymium combinations create 2 dB more sound pressure, which is reflected in the form of 133 dB compared to 131 dB Max SPL @ 1m. RCF states that all woofers are tested for over 200 hours to detect any quality problems before they are delivered.

Otherwise, the design is very similar to the other representatives of the 9 series, which were already convincing in the smaller versions. Here, too, the entire product is manufactured in Italy, which on the one hand counteracts the omnipresent supply chain problem with China and on the other hand supports Europe as a production location with its higher standards in terms of labor and human rights. You may call me naive, but I will probably always be a "Support Your Local Dealer" sympathizer, although some electronic components in the RCF ART 915-A will definitely come from China.

This representative of the 9 series also shines with a wide range of applications due to its high flexibility. Due to its asymmetrical housing shape, the RCF ART 915-A can cover several sound options at once, although the voluminous exterior in combination with corresponding subwoofers clearly points towards a small PA. Even without the appropriate woofer support, one or two DJs will use the high-stand version as a mobile sound system, which should also be sufficient for small halls. It can also be used as a floor monitor and sidefill, although the stability and tipping safety are completely sufficient for regular wedge operation, but do not come close to the stability of a pure wedge. The system also has M10 threaded inserts on the top and bottom, or side panels of the housing for flown fixed installations. For high-stand operation, the box has a robust 36 mm steel flange on the bottom.

With dimensions (H x W x D): 717 mm x 415 mm x 410 mm, the box is in the middle segment in terms of transportability, although the 24.2 kg weight puts a lot of strain on the arms and a second person may be needed to place it on the high stand. The housing of the RCF ART 915-A is made of polypropylene, which, with a combination of comparatively low weight and good elasticity, should absorb both internal vibrations and major external impacts well. For better protection, I would also recommend the corresponding protective cover from RCF, which can be purchased separately. Even if it is “just” a sound system, worn-out speakers always leave an inferior impression.

Two generously sized recessed grips on the sides ensure good handling and easy transport, which not only make it more comfortable to carry, but also make it much easier to balance on a stand. The two grip slots on the top and bottom of the housing, which are familiar from the smaller models, are missing here, probably because a weight over 20 kg would no longer be adequately transportable in this form. The loudspeaker equipment consists of a 15" woofer made in-house and a 1.75" tweeter, which together can deliver 1050 watts peak, i.e. around 500 watts sine, and boasts 2100 watts peak for those with a penchant for numbers. The frequency response of the system is specified as 45 Hz - 20000 Hz, the horizontal radiation angle is 100°, the vertical radiation angle 60°. The manufacturer also points out the new filter technology called "Firphase" as a special feature in this series, which, according to the company brochure, guarantees "a transparent sound image, absolute clarity and a perfect stereo image with minimal latency without phase distortion".

In terms of accessories, RCF does indeed offer a wide range of stands and mounts, both for use close to the ground and for flying. It is worth checking out the manufacturer's website to see if you can find something that comes closest to your personal use case.

The back

As with the other two representatives of the 9 series, which have already been discussed, all connections are on the back of the housing, although RCF has also reduced the operating options to a minimum here and transferred the entire sound signal management to a mixer connected in front of it. To what extent this represents an advantage or disadvantage is something each user has to find out for themselves, but the fact remains that the advantage of a spartan equipment is that even less experienced users cannot cause major damage in the case of mismatching. The disadvantage, however, is that experienced users have to make almost all frequency-related settings using an external console.

All controls are installed very deep in the housing and are therefore very well protected from external influences, provided they are flat on the panel. The alignment and arrangement is identical to the 932-A, so we also find the following controls here. An XLR / TRS combo input socket, combined with a volume control, serve the user as input management. In addition, a push button enables a rough pre-selection of the applied signal level, consisting of the presets "Linear", "Boost" and "Stage", the respective activation of which can be read off via 2 green LEDs. Unfortunately, there is no gain control here either, so you should keep an eye on the overload displays in the master area when outputting the signal via the mixer. The system also offers an XLR out for daisy chain operation. The system status can also be read off via 2 LEDs (signal - green and limiter - red).

Finally, in the lower part of the housing below the cooling fins of the system, there is the on/off switch plus the cold device socket and the internally installed main fuse. The system does not have a multi-voltage power supply and is approved for either 220 - 240 volts or 100 - 120 volts mains voltage. The values ​​of the fine fuses used also behave accordingly.

The RCF ART 915-A in practice

Of course, the area of ​​application of the RCF ART 915-A is very broad, but the primary purpose will most likely be as an easy-to-transport sound system in the DJ area. This is where the RCF ART 915-A can really show off its strengths, which is particularly evident in the combination of relatively good transportability together with a powerful level. Nevertheless, like other active speakers before it, the full-range box had to undergo my standard test routine for flexible full-range boxes, i.e. operation as a floor monitor in the studio, high-stand operation indoors and high-stand operation outdoors up to a distance of 50 meters.

In fact, even with the linear setting, you can see that the 15-inch woofer used moves significantly more air than the slightly smaller sister models, thus enabling a better and more stable presence, particularly in the low bass range. I would even go so far as to say that with the RCF ART 915-A, depending on the sound material used and the size of the area to be sounded, you might be able to save yourself the need for a subwoofer. Despite the performance data, you should of course not have too high expectations of a real "physicality" in the low bass, but you should also not forget that this form of performance is only desired at real dance events anyway and is sometimes even perceived as disturbing in "normal" operation in the party area.

Here, the RCF ART 915-A offers a very tasteful solution that can be installed and operated without much effort. I personally found the mid-range reproduction of the system interesting. In general, when it comes to expectations, I'm always a little prepared for the classic mid-hole in a 15/1 combination, where the woofer is too sluggish due to its mass and the tweeter can't get down. I was all the more pleased that RCF got this problem under control surprisingly well. I couldn't quite figure out whether it was due to the slightly larger compression driver or the greater flexibility of the 15-inch, but the sound result convinced me across the board. For example, I've rarely been as impressed with the guitar playback in a 15/1 combination as I was with the RCF ART 915-A.

The system also impresses with its very stable sound, which is relatively balanced and without any unpleasant sharpness until shortly before the limiter is activated. Overall, this RCF system has to be given a very good rating, including a high level of flexibility in terms of application, particularly in relation to its price, which can be seen as quite cheap despite being manufactured in Europe.

Conclusion

With the RCF ART 915-A, the Italian manufacturer has a powerful sounding full-range speaker with a very stable headroom and unexpectedly good midrange reproduction in its range. The system is very flexible in terms of its use due to its trapezoidal shape and impresses with a neutral basic sound, which offers a very high level including decent sound pressure when required. Anyone looking for a powerful full-range speaker and sometimes wanting to do without a woofer should definitely try the system out.

TEST: Randall Satan 100

 Oh, that's what I call bold marketing! Personally, I'm always a big fan of names that immediately define the area of ​​application and target group. But what Randall has served up here with his Randall Satan is hard to beat in terms of clarity. The devil himself is the namesake and when you turn on the head, the blood-red LEDs light up your face. What I would give to see the faces of the musicians at a blues jam when you heave this amp onto the stage and activate it :-)

Construction

The verb "heaves" is to be taken literally here. With a weight of almost 30 kilograms, you wonder whether you're just lugging the head or whether you've already accidentally grabbed the 4x12 cabinet. The dimensions are within the standard range at 740 mm x 240 mm x 265 mm (WxHxD), but if the amp is also to be transported in a case, you'll need an extra pair of hands. At first glance, the head looks like a relatively normal 2-channel head, but the names of some of the controls make the interested user prick up their ears.

Of course, most of the readers have already guessed, but the Randall Satan has only one area of ​​application, metal. This alone would not be so unusual, but the concept is designed primarily for drop tunings, or the use of 7-, 8-string guitars or even baritone guitars. In 2011, Randall brought Mike Fortin onto the team, who, following his excellent reputation, was promoted straight to chief engineer of the development department. To give the amplifier an additional promotional aspect, the amp was designed as a signature amp, but the relatively unknown guitarist Ola Englung was brought on board as the namesake. He has been playing the strings of death metal veterans Six Feed Under for 2 years, among other things. The fact that Randall doesn't really believe in the endorsee's appeal can be seen in the fact that the name only appears in small letters without a signature on the back of the case, while the Nullifier signature amp by Anthrax guitarist Scott Ian, which was also recently released, has the typical signature on the front.

Despite being made in China, the amp costs almost 2,000 euros, which suggests that it has various special features. The first thing you notice when activating the head is the uneven row of output tubes. This is due to the fact that the Randall Satan uses 2 6L6GC and 2 KT88 for each half-wave. Anyone who knows how the KT88 reacts to bass frequencies will understand the purpose of this unusual circuit. The second major feature can be found in channel 1 of the head. While channel 2 is comparatively normal with a three-band tone control (bass, middle, treble), a shift control for the midrange, a bright switch and the typical gain/volume control, the names of the controls on channel 1 are enough to attract attention.

Interestingly, Randall has revived the somewhat out-of-date system of 2 inputs. An active and passive socket each provide a pre-selection in terms of input sensitivity, although I personally prefer to use the passive input with an active guitar. But you should definitely try it out for yourself.

On the far left are two controls, the martial "Birth" and "Grind", which, together with the gain control, influence the distortion spectrum separately in their frequencies, with the birth control taking over the bass range and the grind control taking over the treble range. Funny detail on the edge, all three controls have a "6" instead of the normal initial letter, which together makes the classic "666". So if you plan to play with the amp in the USA, you should be very careful not to fall into the hands of fundamentalist Christians if you want to leave the venue in the same condition as before the show.

As far as I know, this is the only amp in the world that has three distortion controls in a single channel. This is followed by a sweep control, which shifts the starting point of the three-band tone control again. All in all, an extremely variable sound spectrum to serve the extended frequency range of the instruments mentioned above. As the icing on the cake, you can then activate a "kill" switch (all that's missing is Blood, Steel and Sword and you have a Manowar signature amp), which increases the high-mid range. The master section finally has master volume, presence and a depth control.

The back of the head is also blessed with great flexibility. The internal FX loop can be operated in parallel or in series and has been provided with a level potentiometer. Channel changes, kill boost and FX loop can be remotely controlled via two footswitch sockets, whereby the first two functions can be carried out using the footswitch supplied. 5 speaker outputs allow any speaker combination you like. The amp also has 2 direct outs, one with speaker simulation in XLR and an untreated TSR. Finally, there is the bias section, which allows the optimized calibration of the output tubes outside the housing.

Practice

As expected, the bass range of the Randall Satan was designed from the ground up to be transparent. With the 8-string guitar at the latest, you are already completely in the area where only the classic bass is at home, which presents completely new challenges for both the loudspeaker, tone control and the arrangement of the songs. It is not for nothing that there are already several bands that do without a bassist altogether and have the low frequency range covered either by two eight-string guitars or by a combination of eight-string guitar and keyboard player.

In order to escape the complete bass mush, especially in the high gain range, a very difficult adjustment is required in terms of compression and sound spectrum. So it's not surprising that the Randall Satan isn't really an ultra-bass woofer. At room volume, this might inspire the inclined user to ecstasy over the fat bass reproduction with his instrument alone, but for practical use in a band this makes little sense. The risk of thick slobber below the 300 Hz mark is too great, which always has a detrimental effect on the overall sound and the composition.

In fact, the concept of the three gain controls works perfectly and allows for finely graded distortion behavior. In combination with the sweep control, you should take plenty of time to find your personal sweet spot in the frequency spectrum, depending on the volume used; it's worth it. Don't forget that the unusual power tube combination does its part to ensure that the volume increases in terms of punch. And the 120 watt bolide certainly has plenty of headroom.

Although the focus is on channel 1 of the amp, as expected, you shouldn't make the mistake of viewing channel 2 as a mere extra. A high dynamic reserve ensures very clear, undistorted sounds and also allows for a considerable range of crunch sounds.

Conclusion

The Randall Satan is a product in the American manufacturer's range that consistently relies on high gain and downtuning. With a previously unique triple gain control, the head manages to maintain great signal transparency even at maximum gain and an octave below the standard guitar tuning. With extensive tone control in channel 1 and in conjunction with channel 2, the head also offers an extremely high tonal variety that many other high gain amps lack.
Even if the amp also adapts regular tunings without any problems, anyone who primarily uses 7-string, 8-string and baritone guitars in various metal genres should definitely give the amplifier a try.

TEST: Randall Satan 50

 Hell, hell, hell! When it comes to packing the maximum amount of Antichrist into a product name, the company founded by Donald Randall in 1970 would be way ahead with its Randall Satan 50. It should be clear to everyone that this name is not a Twin Reverb successor in terms of sound. Consequently, the Satan package is tailored from start to finish to the metal sector, so let's be surprised by what Mike Fortin, who developed the amplifier concept, has come up with.

In the devil's kitchen!

The Randall Satan 50 is not the first Beelzebub of its kind. Almost 4 years ago, the Satan 100 was the first Mephisto made in China to appear on the scene, bringing the name Ola Englund to the fore. The Haunted guitarist, who comes from the YouTuber scene, is the namesake of the amplifier. Sales figures will show whether Randall has done himself a favor by using this fairly well-known name as a draw. Signature amplifiers are a tricky thing in general. Even with commercial heavyweights Kirk Hammett and Nuno Bettencourt, Randall is having a relatively hard time establishing its signature products on the market. It remains to be seen whether this will change with the Swede.

The structure of the Randall Satan 50

The Randall Satan 50 is a two-channel all-tube amplifier, the first thing that comes to mind is its weight! Although the housing is quite compact with dimensions (W/D/H): 50 cm x 27 cm x 27 cm, almost 20 kg pull on the support arm, which is a top-ranking product in this size range.

As is often the case in life, this has advantages and disadvantages. Yes, a high weight also has advantages, especially when it comes to the longevity of the product. The higher the potential energy of a body (weight), the more likely it is that an external impulse (e.g. impact or blow) will be compensated. The disadvantage, however, does not need to be described in more detail, it is self-explanatory. The amplifier is supplied without any protective device, so it is strongly recommended to get a heavily padded bag or case for the amp.

Using 3x 12AX7 tubes in the preamp and 2x 6L6 power tubes, the Randall Satan 50 delivers almost 50 watts, which can be very loud, especially since the amp has a strong preference for any kind of bass boost. Like the Satan 100, Randall sees the main use of the amp in downtuning and 7-8 string djent range of ERG guitars, whose main problem is still a clean, accentuated bass reproduction in the high gain range.

The front of the Randall Satan 50

Several unusual details catch the user's eye on the front. Visually, it started with the initial letters "B" and "G" of the first three controls being converted to a "6" to generate a fast "666", and ended with the unusual tone control in channel 1.

I have rarely seen an amplifier that works so uncompromisingly towards high gain as the Satan series. Let's start with the first two controls "6irth" and "6rind", followed by the "6ain" control. While the tone control is normally located behind the preamp, Mike Fortin has placed a bass and treble control in front of the preamp in order to be able to control the level of distortion of the various frequency ranges before they actually distort in volume. This allows for very individual adjustment to the personal instrument.

In conjunction with the three-band tone control with three-way center frequency selection via a mini switch, you can determine and control the sweet spot of your instrument very precisely. Volume control? Not at all! The only volume control available is the master volume control on the far right. Well then.

The second channel is much more spartan, and has a volume control for matching the volume with the first channel, then gain and, in true Fender style, a tone control - that's it. As we all know from vintage amps from the fifties, a rudimentary volume and tone control can generate an excellent sound, but with the Randall Satan 50, channel 2 seems a bit like an extra.

For both channels, there is a martial-sounding "kill" switch in the form of a booster and an additional "depth" and "presence" control in the power amp area. The channel can be selected and the booster function activated using the foot switch provided.

The back of the Randall Satan 50

The back of the Randall Satan 50 comes with a wide range of functions. Firstly, the amplifier offers the option of running with 2 different operating voltages. One voltage from the range 100V / 110V / 120V and one from the range 220V / 230V / 240V is set at the factory and can be selected with a slider. In our case it is 110V and 230V.

Next to the connections for the foot switch there is a calibration point for the output tubes. If you don't like the sound of the 6L6 and prefer the compression and sound behavior of other output tubes, you can calibrate the corresponding pair here using a digital meter. But BE CAREFUL, please find out exactly which mV voltage the respective tubes need beforehand. Output tubes that are set too hot or too cold reduce the sound of the amplifier immensely and shorten the life of the output tubes.

Next comes the amplifier's FX loop, which can be operated in series or in parallel. Using the level control and three sockets, you can choose which operating mode the loop should use. In principle, it's very simple: all the room effects that should be mixed into the guitar signal (delay, reverb) are best mixed in parallel, the rest in series.

Two outputs are available for forwarding the signal. Firstly, an XLR out with a switched-off speaker simulation, which also works in standby mode, optionally with ground lift, and a line out, referred to here as RAW, for the purpose of connecting additional power amplifiers or external effects. Finally, there are 5 different speaker outs with the classic options 2x 16 Ohm, 1x 16 Ohm, 2x 8 Ohm, 1x 8 Ohm, 1x 4 Ohm, which cover pretty much all cabinet configurations.

The Randall Satan 50 in practice

The Americans and their LEDs :-) OK, such a beautiful deep red is practically a must for the product name and it looks great on stage. Unfortunately, you can't dim or turn the light off like you can with the Hughes & Kettner Triamp MKIII, so be prepared for your light mixer to complain again that its beautiful light images will be affected by your amp.

Go straight to the top, channel 1 and off you go. Yes, that is a modern metal sound. The setting options for the 5 tone controls are indeed very extensive, although the basic sound of the Randall is always present. Very American, soft in compression, but still with subtly biting highs. You should try out different speakers here, although I would personally advise against vintage variations. The comparatively small stroke of 30 watt speakers does not go well with the very bass-oriented basic sound of the amplifier; the classic 300 watt cabinet would be a better choice.

The volume control takes a bit of getting used to, which, as already mentioned, is only controlled via the master volume control in channel 1. The channel works relatively well up to 12 o'clock, after which an incredible volume and bass boost suddenly sets in. Although the depth is still at 12 o'clock, the amp pushes immensely at around 200 hertz. An impressive experience, but unfortunately also with the disadvantage of a distorted frequency image. As you can hear from the recordings, the bass range swings so strongly that the regular sound of the instrument is drowned out and strong waves form in the bass range. In a recording, for example, this would mean that you would have to set a high-pass filter and the FOH at a live show will not be so happy about your pumping sound either. A real asset for thin-sounding instruments, but fat EMG attacks should be used with caution.

Channel 2, on the other hand, surprises with a very open, dynamic sound that cannot do one thing above all else: produce clean sounds. No matter how much I turn down the gain control, there is always a hint of crunch in the sound. But in my opinion that's not a bad thing at all, because if you want to raise hell on channel one, you certainly don't expect the Bon Jovi of death metal on channel two.

Conclusion

With the Randall Satan 50, the American manufacturer offers an amplifier whose uncompromising home is the high gain range. With a sophisticated tone control and interesting detailed solutions, the amplifier offers many nuances that could lead the inclined death grind black beat-me-dead metal fan to the Randall camp. To what extent the hefty retail price of just under €1,500 could dampen the euphoria remains to be seen.

TEST: Radial Engineering Voco-Loco

 As a guitarist, you know the problem. Although many music-loving listeners describe the guitar as a more or less cool instrument, you sometimes get a rather disparaging assessment from fellow musicians. While everything that comes from the piano area generally considers guitarists to be cavemen with only a little knowledge of harmonic theory, and singers generally see the function of a guitarist as only accompanying their glory, there is one area that all instrumentalists envy guitarists. We are talking about the sheer gigantic selection of floor pedals for finding and defining your personal sound, which most instrumentalists have no access to due to technical adjustment problems. This is where the Canadian company Radial Engineering comes into play, which once again wants to remedy this problem with a rather unspectacular but extremely useful tool and introduces the Radial Engineering Vocoloco.

The concept of the Radial Engineering Vocoloco

Whenever you have to deal with switches, switchers, impedance converters and DI boxes in the professional field, sooner or later you will come across the company Radial Engineering. The Canadian company, which also has its products manufactured in Canada, generally impresses with very good workmanship and sometimes absurdly simple solutions to technical problems that would otherwise make you want to tear your hair out. In addition, Radial Engineering builds its products to last forever, which means that each product is extremely solid, including the Radial Engineering Vocoloco we tested, whose steel housing weighs almost a kilogram despite its small dimensions of 14.5 cm x 9.5 cm x 5 cm (W x D x H). If you do not attach the Radial Engineering Vocoloco to a floorboard, the product comes with 4 adhesive rubber feet, which offer comparatively good adhesion even on smooth surfaces.

According to the product description, the Radial Engineering Vocoloco is an effects switcher with a built-in microphone preamp, which in my opinion only gives a very marginal indication of the product's capabilities. Rather, the product allows the consistently symmetrical microphone signal to be connected, in whatever form, with the consistently asymmetrical pedals from the guitar-bass area in a common signal chain. It is therefore obvious that impedance conversions must also be used here in order to be able to merge the two worlds of signal routing.

The Radial Engineering Vocoloco must essentially be divided into two areas, which are also visually separated from one another on the top of the housing. On the one hand, there is the microphone preamp, which has a gain control, a bass control and a treble control and, as expected, takes care of the signal from the fed-in microphone. The other area, on the other hand, takes care of the loop function, where the respective pedals are looped in. Here you can separately regulate how much signal strength is output to the effect pedals and how strong the level is that comes back from the devices. There is also a tone control to slightly influence the timbre of the effects and there is also a mix control to adjust the proportion between the effect signal and the dry signal.

Using two foot switches, you can activate or deactivate the effect loop for the pedals separately and there is a mute switch with which you can mute the entire signal chain. This is very useful during breaks in playing, for example. Using a recessed push button, you can also convert the mute switch into an "all wet" switch. To operate the Radial Engineering Vocoloco, Radial Engineering supplies an external power supply. The big advantage of this power supply is the variable attachment of different plugs, so that the product can be used worldwide. The disadvantage of this power supply is its values. With a voltage output of 15 volts direct current at 400 mA, the power supply uses very unusual values, which means that you probably won't be able to operate the Radial Engineering Vocoloco without the power supply supplied. I don't know of any power supply for guitars that has 15 volts. So remember, never lose this power supply, otherwise it won't work.

The strain relief for the power cable, which is placed above the power socket, is also somewhat unusual. As is usual with Radial Engineer, even this small plastic tab is very solid and will probably never break during its service life. The disadvantage, however, is that this tab is so solid that I could not move it forward, let alone to the side, to place the power cable underneath; instead, you have to use a special Allen key to loosen the bracket, place the cable and screw the bracket back on. On the one hand, this is a very durable solution, on the other hand, perhaps a touch over the top in terms of practicality.

There are also three more recessed push buttons on the front of the housing, which can be used to switch various functions. Firstly, we have the phantom power of 48 volts, the activation of which is indicated again by a red LED on the top of the housing.

There is also a ground lift switch on the front and a 180 degree phase switch. Anyone wondering why this product has a phase switch should be aware that many guitar effect manufacturers don't give a damn about phase fidelity, as it is simply not necessary to think about it in terms of sound when it comes to guitars. However, when it comes to microphones, incorrect phase position can lead to the notorious mid-range cancellations, which make the sound sound horrible or even thin. This switch can potentially eliminate this problem. Once again, such small details show how much Radial Engineering thinks about signal routing down to the last detail.

Finally, the Vocoloco also offers a microphone in and microphone out, symmetrical of course, and an asymmetrical effects loop with corresponding jack sockets. The included English-language manual is also very nice, showing the most important functions of the respective control elements down to practical examples of how to best use the Radial Engineering Vocoloco. Interestingly, the operating instructions are only in English. For a Canadian manufacturer, I would have thought that a further version in French would be included with the product.

The Radial Engineering Vocoloco in practice

Although most users imagine using the Radial Engineering Vocoloco in conjunction with a vocal microphone, one should always keep in mind that the product can be particularly useful when using wind instruments or a harmonica, for example. Ultimately, any instrument that is picked up with a microphone can benefit from the system. I still remember very well how Stewart Copeland, drummer for the band The Police, sent his drum rhythms through delay pedals in his early days to generate a spatial effect at live concerts. I can vividly imagine what an effort it must have been at the time to adapt the microphone signals to the corresponding guitar effects.

Otherwise, there is almost nothing to say about the practical part of the Radial Engineering Vocoloco, except that the product works excellently, has no background noise, has no structural problems and does exactly what it was built for, and in the best quality. The preamp can of course only set subtle nuances when it comes to the filter range and the tone control of the effects loop is more or less a nice little extra, but the concept of the pedal is extremely convincing and in my opinion will definitely find its buyers and real fans.

I have heard here and there that some users would have liked an internally installed compressor. Of course this would have been possible, but I think it makes more sense to use a compressor from the pedal range and simply feed it into the signal chain. Personally, I would start by putting together a so-called bread and butter setup, consisting of a compressor, a modulation pedal, a reverb, an echo and, depending on your taste, an overdrive. You should be careful with overdrive; a little distortion is a good thing, but as soon as you get into real distortion, not only does the background noise increase massively, but the risk of feedback is also increased accordingly. But here too, whatever you like is allowed and there is no limit. Of course, you should always keep in mind that there are probably hundreds of thousands of effect pedals now, all of which sound slightly different, so the variety of sounds that the Radial Engineering Vocoloco opens up is almost unlimited.

Conclusion

With the Radial Engineering Vocoloco, the Canadian manufacturer has a product in its portfolio that opens up the gigantic world of guitar pedals to every microphone signal. The concept of merging a symmetrical microphone signal with an asymmetrical guitar pedal is implemented in the highest quality with an excellent concept.

A real asset for every musician who wants to enrich their signal with effects. Definitely give it a try!
