Microphone Mute

Range Sensor for auto-muting a microphone when not in use.

Description

On stage, noise level is high. A gate on the mics is sometimes not sufficient. This device is intended to be mounted directly on the back of the mic, sensor facing towards mic. The trigger-distance is adjustable by pressing the top button. Also, by double-pressing this button, different mute-profiles will be selectable where choices can be the on- or the off-ramp time, and the dampening (gate/expander) in "mute" mode (testing required).
