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
Unity gain is set at the factory. Audio gain is adjusted via a menu option. See “Menu Items” in the
Operation section Chapter 3. Audio gains may also be adjusted via the 9 pin serial port using the
TyLinx Pro Software program (refer to the TyLinx Pro manual), or using Host protocol (see
Communication protocol Ch. 4).
Audio Follow Video and Breakaway Audio Configurations
Component video channel (YC, RGB etc.) signals are switched by separate crosspoint modules.
All crosspoint modules will be switched at the same time. Audio can be switched following the
video or separately after the breakaway.
