Short Stop represents a name change for the original Pro Co Cough Drop, a passive momentary microphone-muting switch.

To operate, the users microphone cable is plugged into the Short Stop and the Short Stop is plugged into the sound system. If the entertainer has to cough or clear his/her throat, he steps on the Short Stop's momentary switch pressing and holding down the switch, muting the microphones signal to the sound system for as long as necessary, preventing embarrassing sounds from reaching the audience. Releasing the foot-switch (which can easily be used as well as a hand-operated unit) allows the entertainer to resume normal communication with the audience.
