AKG used NAMM as the venue to launch the DMS 700 digital wireless microphone system and full-featured performance audio system. The system consists of a 1RU two-channel receiver paired with either handheld or bodypack transmitters. The system offers an exceptional 155MHz tuning range for both receiver and transmitters, operating from 543MHz to 698 MHz, safely below the 700MHz band. Onboard functions are many and robust, including digital encryption of audio.
The system’s digital audio transmission is very clean, eliminating the high-frequency distortion and significant noise levels associated with analog systems. The DMS 700 offers a high total channel count, with the ability to operate up to 100 channels simultaneously. A quick set-up system finds and deploys open frequencies automatically, easily transferring all operational parameters to the transmitter via infrared link. Total latency of the system is just 4ms.
In addition to the expected system set-up functions, the DSR 700 two-channel receiver includes internal DSP that provides features such as a low cut, three-band EQ and dbx compressor and limiter. The built-in environment scan function is a spectrum analyzer that displays RF activity across the tunable spectrum (plus adjacent channels), with zoom ability to watch a specific range. These built-in features essentially create channel-strip control of the wireless system, but also enable full integration and control with other Harman products via HiQnet control protocol.
Available transmitters include the DHT 700 handheld and DPT 700 bodypack, both with rugged metal housing and variable output power of 10mW-50mW. The handheld is available with either the D5 supercardioid dynamic or C5 cardioid condenser element. The bodypack transmitter accepts any common mic or line-level input with no need to adjust sensitivity. The audio input is a TB3M connector that supports a wide range of lavalier, head-worn and instrument microphones. Both units get eight hours of operation from a pair of AA alkalines.
The DMS 700 transmitters are designed to get full professional performance from rechargeable batteries as well. The optional CU 700 uses DC-pulse technology to rapidly charge rechargeable batteries while still inside the transmitter. The microprocessor-controlled charger determines the optimum charge current and has a cooling fan to help keep cell temperatures controlled. Charging is terminated when both batteries are fully charged.
