Cough Button
The talker can turn off his or her microphone during coughing or private conversations by installing an SPST push
button switch between the MUTE IN and Logic Ground pins for each channel to be modified (see Figure 6). When
a channel is muted, no audio is passed. (See
Dead Zone on MUTE IN Defeat
paragraph in the
Internal Modifica
tions
Addendum for more information on MUTE IN logic.)
FIGURE 6: COUGH BUTTONS
Chairperson-Controlled Muting
The chairperson can, by activating a switch, silence all other microphones and be heard without interruption. For
operation in this mode, connect all the MUTE IN pins together except that of the chairperson's channel, and wire
an SPST pushbutton or toggle switch between those MUTE IN and Logic Ground pins (see Figure 7). An alterna-
tive to a switch is to connect the chairperson's GATE OUT to the MUTE IN of other channels. When the
chairperson's microphone activates, all other microphones mute.
