Glensound GS-COUGH001 - Single-Channel Passive Cough SwitchThis is a very simple passive beltpack box. It is robust and lightweight. It houses a high quality switch capable of silently switching mic signals (and line levels) on and off. The switch (a lever key) is a momentary action and in its normal state allows audio to pass from the input to the output. Two XLRs for audio input and output are provided.
