The input that is used for the channel (mic or line) is specified with the Input Select
button (13-a).
Caution:
To avoid potential equipment damage, d48V phantom power on
the channel before connecting or disconnecting its XLR input.

Connect the powered monitor speakers (or speaker amplifiers) here. Volume is set with
the Level knob (1) when Monitor is selected (8) with the Monitor button (11).

These ¼” phone outputs are accessed via software (Console or DAW). Line outputs 3 & 4
