Installation: Balanced Audio Connections
Connecting Audio Inputs and Outputs
All audio connections should be balanced to ensure the best performance. Unbalanced signals may be used if necessary; follow
the wiring guidelines below for recommended unbalanced termination.
The audio input jacks are female 3-pin XLR /TRS “combo” connectors. They will accept male XLR plugs or TRS (tip-ring-sleeve)
1/4-inch phone plugs. The audio output jacks are male 3-pin XLR connectors.
Balanced connection is recommended for all inputs.
The XLR - TRS “combo” inputs are electronically balanced.
Balanced input cables are recommended to minimize noise
pick up and prevent ground loops.
Refer to the pinouts provided (below) for proper connection.
