Connecting To Audio Devices

Audio sources and output devices (such as amplifiers or recorders) are connected to the

switchers through the terminal block connectors located at, and marked, on the rear of the

switcher.

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.
