Connecting to Audio Devices
Mono Analog Audio
Audio sources and destination devices (such as amplifiers or recorders) may be connected to the
switchers via a 5-pin latching, removable, terminal block style connectors located at the back of
the switchers.
Balanced/Unbalanced Analog Audio Connections
All audio sources from the routing switcher are balanced audio. Connect the balanced audio to
the balanced input of your destination device(s). To convert balanced to unbalanced audio
signals, ground the negative (-) side and use the positive (+) side for both inputs and outputs.
Grounding the negative side of the output drive adds +6dB of audio gain. The audio pin outs for
balanced and unbalanced audio are described in the tables below:

Input and output connections differ when the unit is in the stereo mode.
In the mono mode connectors are wired as silk screened on the rear of the router. However,
