The DSR 700 digital true-diversity receiver offers an ultra-wide bandwidth of up to 155 MHz for 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 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.
