Gain control

In quick access mode, gain control applies for sets of output channels having input channels in common in their input

selections (see also section 4.2.1). The gain control procedure is the following:

From the main screen, press and hold the chosen output key, say OUTx. 1.

The LCD displays the gain values of all output channels having in their input selection an input channel in common

with the input selection of OUTx.

Turn the encoder wheel to modify the gain values and simply release the key to return to the main screen. 2.
