Mute Control

The mute control provides a way to mute
individual outputs, or all outputs at once.
Audio and video for each output is muted
simultaneously.
Each output is assigned to a pin on the captive
screw connector. To mute any output, short
its pin to the ground pin ( ). Multiple outputs
can be shorted at the same time. To mute all outputs at once,
short pin A (all) to the ground pin.
The P/2 DA8 A model uses two 3.5 mm, 5-pole, captive screw
connectors. The P/2 DA12 A model (shown above) uses two
3.5 mm 4-pole connectors and two 3.5 mm 3-pole connectors.
For connections to captive screw receptacles, the length of the
exposed wires is critical.

The ideal length of stripped wire is 3/16" (5 mm):
• If the stripped section of wire is longer than 3/16",
the exposed wires may touch, causing a short circuit
between them.
• If the stripped section of wire is shorter than 3/16",
the wires can be easily pulled out even if tightly
fastened by the captive screws.
Do not tin the wires. Tinned wire does not hold its
shape and can become loose over time.
