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

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.
