2.1. Operating Modes
Each output channel may be configured to one of two modes of operation by setting the DIP
switches according to the ON indicators on the audio distribution amplifier.
Fixed output
Keeps the output channel set to a specific input channel: either A, B, or C.
Switched output
Allows the user to select input channels independently of the other output
channels. Requires a source select switch wired to the unit.
3. CONFIGURATION DIP SWITCHES
Use the configuration DIP switches to set the audio control for all seats. Each output channel uses
two switches. Figure 1 shows the pairs of switches that control each channel.

3.1. Auxiliary Configuration Switches
The Headphone Distribution Amplifier features an optional 5V power supply that will handle up
to 0.5 A.
The Channel C Control is an optional switch that enables the third audio input. Leave these
and any other unused switches OFF (up) unless you need to configure them.
