155 MHz ultra-wide frequency range
The DSR 700 V2 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 MHz-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.

Encryption & digital transmission
Digital transmission makes it possible to broadcast sensitive audio information with absolute confidence. The 512 Bit 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.

HiQnet® - System Architect
With the optional HUB 4000 Q, AKG wireless systems can be integrated into a HiQnet® system. The wireless system can be remote-controlled and monitored with the Harman control software System Architect™ (from a PC), the AKG Wireless iPhone App (from an iPhone/iPod touch/iPad) or VM2 (from a Soundcraft Vi mixing console). The setup and configuration of the frequency management of a multichannel wireless system is incredibly easy within the System Architect™ with tools like 1 Click Setup, RF Monitor, Device Manager and Environment Scan.

Consumer Alert (for US users)
Most users do not need a license to operate this wireless microphone system. Nevertheless, operating this microphone system without a license is subject to certain restrictions: The system may not cause harmful interference; it must operate at a low power level (not in excess of 50 milliwatts); and it has no protection from interference received from any other device.
Purchasers should also be aware that the FCC is currently evaluating use of wireless microphone systems, and these rules are subject to change. For more information, call the FCC at 1-888- CALL-FCC (TTY: 1-888-TELL-FCC) or visit the FCC’s wireless microphone website at www.fcc.gov/cgb/wirelessmicrophones
