Sennheiser EW 300 G4-HEADMIC1-RC-GBw CH38

The Sennheiser EW300 G4-HEADMIC1-RC-GBw Headworn System with SL1 Omni Headmic on channel 38 uses the power of an increased switching bandwidth of up to 88 MHz.

New frequency ranges allow to operate multi-channel setups with dozens of channels while securing reliable operation - despite digital dividend.

The powerful professional HEADMIC1 is the pro’s choice for lively lectures and speeches. Its high speech intelligibility makes the headset microphone besides its good look absolutely reliable.

Remote mute switch available for the bodypack transmitter.
