Mic attenuator (mute) with user definable switch function
Add any closed contact switch to operate
Professional XLR-type input/output connectors
Can be installed anywhere in-line, either at the mixer input or near the microphone
Runs on 24-48V DC phantom power and permits phantom voltage to pass on to the microphone
Rugged steel housing Mic attenuator/MUTE with user definable switch function

The AT8684 is a versatile attenuator that permits easy in-line switch installation and flexible application. Type of external single-pole switch the user supplies determines muting function; closed contact causes muting. Use for on/off, push-to-talk, push-to-mute, etc. (Additional, isolated poles on the switch may be used to control logic-level DC circuits.)

Just add any twin cable switch to operate (eg - 'light switch' type on/off switch, keyboard foot pedal etc)

If using a foot pedal we recommend a latching type so you press once to mute and press again to activate the signal (mic on).
