Sign Off represents a name change for the original Pro Co Cough Drop L version, a passive latching microphone muting switch (press to mute, press again to unmute).

To operate, the users microphone cable is plugged into the Sign Off and the Sign Off is plugged into the sound system. If the entertainer has to cough or clear his/her throat, the user steps on the Sign Off to mute the microphone's signal. Pressing the switch again unmutes the microphone and resumes regular communication with the audience.

Designed especially for singing drummers, the Sign Off will work well for any entertainer who needs a latching rather than a momentary microphone muter.
