155 MHz ultra-wide frequency range
The DSR 700 digital true-diversity receiver offers an ultra-wide bandwidth of up to 155 MHz for a robust and most flexible operation. Select the receiving frequency from pre-programmed frequency groups and sub-channels of your receiver or set it directly in 25 kHz-increments. Each pre-programmed frequency group provides up to 40 intermodulation-free channels*. It has a better resistance to interference to provide more channel security and reliable transmission. Using both frequency bands and a customized frequency table allows operation of more than 100 channels simultaneously.
Encryption & digital transmission
Digital transmission makes it possible to broadcast sensitive audio information with absolute confidence. The audio encryption offers you the highest security for, courtroom, boardroom and other confidential meeting applications.
The transmitter uses a digital data stream to transmit battery and mute status to the receiver.
Quick & easy setup
Great attention was paid to ensure an easy and user-friendly operation with a quick setup feature. The receiver will find interference-free channels and transmit the related setup data to the transmitter via infrared.
Environment scan - Spectrum analyzer
The Environment Scan function converts the receiver into a spectrum analyzer. It searches the receiver’s entire frequency band for active radio frequencies and shows them in a frequency spectrum graph in the display.
Digital Signal Processing
The build-in digital signal processor offers a variable low-cut filter, a semi-parametric equalizer, a dBx® limiter and compressor.
* The actual number of channels that can be used simultaneously depends on local frequency plans.

DPT 700 is a highly-professional bodypack transmitter with a rugged all-metal chassis. The ultra-wide bandwidth of up to 155 MHz and up to 50mW RF output power provides the most flexible operation. An infrared data link will send all setup data to the assigned transmitter. The bright graphic display shows channel, frequency, output power and battery status information.
The DPT 700 has a jack for an optional external mute switch that mutes the audio signal even when the transmitter is not easy to reach. The 3-pin mini-XLR audio input is compatible with any lavalier or headworn microphone and provides a bias voltage of 5V (the connector has to be modified for non-AKG microphones)
The number of channels that can be used simultaneously depends on local frequency plans.

AKG’s CU 700 is a fast charger that rapidly charges the rechargeable batteries inside the transmitter without damaging the cells' elements. The CU 700 charger determines the optimum charge current and has a cooling fan to help keep the temperature of the cells under control.
Charging is terminated when both batteries are fully charged. The CU 700 charger use the pulse technology in which a pulse is fed to the battery. This DC pulse has a strictly controlled rise time, pulse width, pulse repetition rate (frequency) and amplitude. With pulse charging, high instantaneous voltages can be applied without overheating the battery.
