AKG DMS 700: first wireless microphone system with fully digital transmission

Faced with the increasingly frequent interference problems in wireless microphone systems derived from the coexistence of analogue and DTT frequencies in television and data transmission, AKG launches a totally digital system with intelligent management of free channels.

After several years of intense research, AKG seems to have found the solution to the headaches of sound technicians who, when it comes to providing sound on a set, encounter a tangle of frequencies and harmonics derived from the current coexistence of analog and digital television signals as well as the increasing presence of data transmissions in public and private environments. The solution is the new DMS 700 system that incorporates a digital encryption system for signals in a wide range of frequencies and channels (up to a hundred channels can be preconfigured with a bandwidth of 155 MHz for both receivers and transmitters). Encryption allows the codes to be configured so that only the sender and receiver can decode the signal, thus making it inviolable and at the same time protecting it from interference due to spectrum saturation.

The receiving station of the new AKG DMS 700 includes DSP processing for filter configuration, three-band equalization, compressor, DBX limiter and spectrum analyzer. As for the handheld transmitter, the DHT 700 has a 50 mW helical antenna and AKG D5 supercardioid and cardioid capsules. The DPT 700 bodypack accepts both mic and line signals without having to adjust the input sensitivity. Its two conventional AA batteries ensure perfect use for eight hours, although it can also be used with rechargeable batteries with the CU 700 charger.
