TEST: Aphex 204

 APHEX! A name like Donnerhall! At least if, like me, you have been dealing with studio technology for over two decades or sometimes have to sit down. “Donnerhall?” the younger readers will suspect, “what is so incomparable about the company name?”

I dare say that EVERYONE has heard the name Aphex at least over 1000 times in their life, even if in such a subtle way that they are not aware of it. In the eternal top ten studio list, the experienced sound engineer will seamlessly place the American manufacturer in the “eternal best list” alongside more illustrious names such as Nieve, Studer, Focusrite and Eventide based on a single product alone.

We're talking about the Aural Exciter, a product that was born from a radio and television technician's accidentally miswired circuit and was given the final shine for decades as the last link in the cumulative chain of countless hits in world history. At the end of the seventies and beginning of the eighties, the device was so popular that you could only rent it for an hourly price of 30 dollars (!). Purchasing it was forbidden for fear of a copy of the circuit technology! One can imagine that only the big players in entertainment and broadcast technology had the necessary budget to secure this exquisite sound.

In times of the mass phenomenon of music, even legends cannot avoid revising their product range so as not to gather dust in the memories of yesterday. Aphex is now bringing a new edition of the 104 onto the market under the product name 204, which has several improvements compared to the previous model. Interestingly, Apex still manufactures its products in the USA and, like almost all of its colleagues, did not succumb to the temptation to move its production cities to the country without human, animal and environmental protection, China. Respect!

The Aphex 204 looks pretty, with its front made of brushed aluminum, framed in a height unit. The product is designed completely in stereo, all control elements are designed twice, so that you can also use it in mono. However, a link switch, which would be useful for mastering a stereo file, for example, is missing.

The Aphex 204 contains two trademarks with which the manufacturer manifested its reputation among sound engineers. In addition to the Aural Exciter, which is responsible for the upper frequency range, there is also the so-called “Big Bottom”, which, who would have thought, covers the bass range. Due to the fact that the product does not increase the frequency range in terms of performance like a shelving filter, the big bottom circuit also provides a kind of protection circuit for the low bass range.

You can increase the subjective bass response without destroying the bass speaker by overloading it. A sensible setup, especially when it comes to sound reinforcement with small speakers. Background sound systems, demonstrations or broadcasting in general will benefit immensely from this circuit.
On the front, a channel is divided into two areas each with three controls. The Big Bottom is divided into the areas “Drive” (effect level), “Tune” (starting frequency) and “Mix” (dry/wet mixing ratio). The Aural Exciter works in a similar way, which can also be controlled via “Tune”, “Mix” and “Harmonics” (number of overtones). Each channel also has its own bypass switch.

On the back, the product has consistently symmetrical signal routing, either via lockable XLR plugs or jacks. Two slightly wonky slide switches allow you to choose between the home recording level -10 dB or the studio level +4 dB. The device is cleanly processed and gives no cause for criticism.



Practice

OK, what does an Aural Exciter actually do with the signal? The magic word is “Harmonics” or in German “overtones”, although in this case you can also bring a few “undertones” into play. The sound of an instrument is defined by its number of overtones and undertones. In general, one can say that the aggressiveness or sharpness of a tone increases with the number of overtones. For example, a trumpet with a high number of overtones sounds sharper than an oboe, which has comparatively few overtones. By the way, a clean sine wave does not occur in nature, but can only be created artificially with an oscillator.

This means that the Aural Exciter (some competitors also like to call their products “enhancers” or “expanders”, thanks to trademark protection laws...) can breathe additional “freshness” into a signal by generating frequencies that are not (yet) present during the recording process were. This is not an equalizer or shelving filter function that simply boosts previously defined frequencies, but rather the tonal source material is analyzed and “harmoniously supplemented” accordingly.

If you switch on the device and use the unspectacular “everything at 12 o’clock” setting as a basis, even with this insignificant basic setting, it suddenly becomes clear why, in those days and even today, a murmur goes through the rooms as soon as the device is activated . If you're ever in danger of never wanting to put a product down, that's the case with the Aphex 204! The audiophile addictive nature that this product creates within seconds is unbelievable! Every signal that is fed to the aphex experiences a very special kind of refreshment.

The device impresses across the board, especially in the mastering process. Ultimately, everyone has to know for themselves whether they prefer a hardware or software solution for editing their audio material. However, if you prefer the haptic experience, the Aphex 204 is the first choice! I can only recommend deactivating the device regularly, or you will completely lose the feeling for the neutral sound of the source material.



Conclusion

There are not many audio products that add such a distinctive timbre to an output signal that they actually have to be called a trademark. The Aphex Aural Exciter is undoubtedly one of them, as it gives the end product the sound of a real instrument. Often copied and rarely equaled, the product knows how to set standards even 35 years after its market launch, which drives its competitors to the development tables in droves.

Unobtrusively and yet effectively, the product adds exactly the loudness effect to the sound material that the ear canals like to perceive and fortunately has nothing to do with the “bathtub-EQ-GTI-car-stereo-idiot” department. With excellent sound and very good workmanship, the product can only be given the highest score! Respect!
