TEST: AKG DMS 700

 It's actually like everywhere in the instrumental sector, the further you climb up the quality level, the fewer providers you meet on your way up. Interestingly, this pyramid structure is extremely developed in the area of radio links. To be honest, I could only list 3 providers that I have come across in the wireless signal transmission league in recent years.

The “acoustic cinema devices”, better known under the name AKG, undoubtedly belong to this manageable group. With the DMS 700 Band 2 system, consisting of the DHT 700 handheld transmitter, the DPT 700 pocket transmitter and the two-channel DSR 700 dual receiver, AKG delivers a coordinated system which was additionally equipped with the HC 577 L headset microphone for test purposes.

While AKG was for a long time one of the last protagonists of “production in its own country”, in this case Austria, parts of its production are now also moving to China. The above-mentioned transmitters and the headset will continue to be delivered with “Made In Austria”, but the receiver, on the other hand, will be delivered in P.R.C. due to low wage and social security costs. manufactured.

DSR 700 Band 2: 1 height unit in standard 19 inches make the receiver look like an old familiar. In terms of processing, the product performs flawlessly as expected, nothing wobbles or is improperly processed in any way. A large display provides easy-to-read information about all relevant information about the two-channel product.

On the front, editing is only possible using an endless controller with a push function, two channel selector switches and a back pressure switch; the way it works is self-explanatory. Unfortunately, the pressure switches have a slightly sloppy grip; a little more lateral support and a clear pressure point would be desirable in this price range.

On the back, the receiver has symmetrical XLR and unbalanced jack plugs, a ground lift per channel and, as a special feature, a digital AES/EBU output so that you can directly control a digital console, for example. According to this interface, both signals can be transmitted via a connector. The product also has a Wordclock BNC 48 kHz In and two 50 Ohm BNC antenna plugs.

The system has a very wide frequency range of 710-865 MHz ("Band 2" model, the "Band 1" model only supports 548-698 MHz.), which is switched in 25 kHz steps and with a switching bandwidth of works up to 155 MHz. The transmitter powers can be switched between 10, 20, 30 and 50 mW. A higher transmission power would make no sense, as within Europe you have to limit yourself to a maximum transmission power of 50 mW.

Each channel features a dbx compressor and a dbx limiter, plus a tunable high-pass filter and a tone control with bass, semi-parametric mids and treble. As additional features, the product has a quick setup mode, a spectrum analyzer and a battery status display. The device requires a latency of only 4 ms and transmits the data to the transmitter via infrared.


DHT 700 Volume 2: The handheld transmitter is both visually and technically coordinated with the DSR 700. The frequency bands match as expected and the output power of a maximum of 50 mW is also tailored to the receiver. The dynamic microphone, housed in a solid metal housing, has a D-5 capsule and has the supercardioid pattern that is so popular with vocal microphones.

7 segments provide information on a small display about the status of the 2x AA batteries, which, according to the manufacturer, should have a lifespan of up to 8 hours. When using batteries, the energy dispenser could also be charged via charging contacts on the housing. At 336 grams (without batteries), the relatively massive product is also pleasantly light and will not cause any discomfort due to excessive physical exertion, even during extensive live use.


DPT 700 Volume 2: The output of the digital pocket transmitter is technically identical to the handheld transmitter over a large part. Frequency bands, output power, visual display and battery life are identical, which suggests that the inner workings are technically identical. The pocket transmitter comes in a very robust metal housing and has a strong clip on the back, which will not easily leave the waistband or belt unintentionally, even during tough stage use.

The connection used is a Mini an extremely rare connection format.

The DPT 700 also has a few useful features such as the ability to connect an external mute switch and charging contacts on the housing. Here too, data transmission to the receiver is controlled via infrared.


HC 577 L: You can already tell from the skin-colored outfit; a product should not be noticeable here, as is desired for presentations or TV recordings. The condenser microphone is very easy to adjust, is ultra-light, but must be operated with phantom power and can only be operated with an AKG pocket transmitter! A pity...

The anchoring of the microphone capsule also allows a replacement microphone to be attached to the other side, for example for outdoor opera performances. There is also a drip ring on the microphone capsule, which is made of Teflon and can be easily removed from sweat and make-up.




Practice

The fact that there shouldn't be any technical problems with a product in this price category is actually a point that doesn't need to be commented on further, but it shouldn't go unmentioned. All components worked to complete satisfaction. But why should you pay almost €4,000 for all the products presented when there are significantly cheaper products from the competition that at first glance offer an identical or at least similar range of services?

On the one hand, there is the general range of functions in conjunction with the processing of the products. Nothing is really left to chance here, especially since the editing and control options for the applied signal are all-encompassing. The independent dbx components plus the tone control do their part to ensure the highest possible quality signal management.

Point two, which is even more important for most users, is the excellent audio quality of the radio link. 24 bits at 44.1 kHz reach a bit rate of 200 kbps with data compression and make the signal appear in the best quality, mind you, with only 4 ms latency. Both the handheld transmitter and the headset stand out thanks to their clear, neutral, AKG-typical sound, which has not been seen as a guarantee of high quality in the high-price range for decades.



Conclusion

With the DMS 700, AKG delivers a high-quality radio link for the highest demands. The workmanship, proof of performance, components and, above all, the sound of the product are at the highest level. Small drawbacks such as a missing adapter or the lack of interchangeable capsules hardly diminish the excellent impression of the product.
