1 Brief description

With this wireless monitoring system for stage and broadcast use, the listener can directly monitor the received sound signals without troublesome cables or monitor speakers being required. In addition, the monitoring system can also be used for any application where talk- back signals are to be transmitted.

The system has superb audio quality with an increased signal-to-noise ratio and dynamic range due to the inclusion of Sennheiser’s HiDyn stage noise reduction system.
