XLR and 1/4" Combo Input Jacks
The first two input channels may accept a balanced mic or line-level signal using an XLR connector.
They are wired as follows, according to standards specified by the AES (Audio Engineering Society).
In addition to accepting balanced mic or line-level signals using an XLR connector, these inputs may also accept 1/4" line-level
signals driven by balanced or unbalanced sources.
To connect balanced lines to these inputs, use a 1/4" Tip-Ring-Sleeve (TRS) plug. "TRS" stands for Tip-Ring-Sleeve, the three
connection points available on a stereo 1/4" or balanced phone jack or plug. TRS jacks and plugs are used for balanced signals
and stereo headphones and are wired as follows:
To connect unbalanced lines to these inputs, use a 1/4" mono (TS) phone plug, wired as follows:
