Installation: Unbalanced 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.

UNBALANCED

Unbalanced inputs can be

used if required. If unbal- anced audio sources are used, it is preferable to use an ap- propriate audio transformer (or other unbalanced-to-balanced “converter”) to provide a bal- anced input. If this is not pos- sible, then it is recommended that the negative terminal and shield terminal be connected to one another with a jumper wire.

XLR

TS (1/4-inch phone)

This style of plug automatically connects the negative terminal to shield when inserted in the jack.

TRS (1/4-inch)

NOTE for above abbreviations: TRS- tip, ring, sleeve (3 conductors)

TS- tip, sleeve (2 conductors)
