Mute
The Audio Mute Inputs on the Master and Slave Controllers are independent in that a 12VDC trigger to
the Master or Salve Mute Input will only mute the zones on that Controller. (If 12VDC is applied to the
Master, only zones 1-4 will mute. If voltage is applied to the Slave only Zones 5-8 will mute.) The trigger
voltage for audio mute can be connected to the Mute Inputs on both controllers in parallel to mute all
zones when 12VDC is present as shown in
Figure 13
.
1.
Using a 2-male to 1-female 3.5mm mono mini plug Y adapter, plug the two male ends into the Mute
Inputs on the C-4.4 Master and Slave Controllers.
2.
Plug a 3.5mm mini plug wire into the female end of the Y adapter and terminate as appropriate for the
device triggering audio mute. Maintain proper polarity.
