Balanced/Unbalanced 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).
If this is a 2-channel system used for stereo audio, ensure that you keep the same phase
relationship. Connect the positive designated pin to the same relative pin on the
destination device of both channels.
To connect an unbalanced device to the switcher, first place a jumper between the
negative (-) and the ground on the switcher (jumper not included.) Then connect the
device positive (+) to positive (+) and shield to ground as shown in the graphic below.
For unbalanced sources, connect the unbalanced source to one side of the balanced
input and ground. The other input does not have to be grounded. Note, always use the
same side of the balanced input for stereo.
Audio Adjustments
There are no “user adjustable” audio gains. The circuit is designed for unity gain.
Audio Follow Video and Breakaway Audio Configurations
Video and Audio signals are switched by separate crosspoint modules. Audio can be
switched following the video or separately after the breakaway. Audio channels can be
configured to “breakaway” from each other (left and right, ect.).
J1 Connector
The connector labeled J1 on the back panel is used to connect other routing devices to
the router, such as an Audio frame or RS-422 machine control switcher.
Contact the factory for correct configuration before adding other devices that were not
part of your original configuration.
