9.1.4. Switching Between XLR and TRS Inputs

The input channels 1-4 have "combo-jacks" that support both XLR and TRS connectors. When a plug is
inserted, the corresponding input must be selected in the input settings. XLR is the default choice in the
factory preset.

The current input mode is shown on the standby screen:

To toggle between XLR and TRS inputs on several channels:

1. While the standby screen shows the input level meters, press and hold the second button next to the

X|T indicator. An instruction is shown on the display and the LEDs next to the input channels change
to off (XLR) or white (TRS).

2. While holding down the button, press the channel buttons next to each input where the TRS input

should be activated. A white LED at the input represents TRS.

To toggle XLR/TRS on a single channel:

1. Use the button next to the corresponding analog input to access its settings.

2. Use the 

XLR|TRS

 button to toggle the change the corresponding input. The active setting will be

highlighted in blue.
