3.5.4 Group Setting
The interface for group assignments contains two sections including input and output labels. a Max imum of 4
groups are available. A channel can only participate in one group. In each same group, the channel volume
adjustment and mute are synchronous. Other module parameters are not synchronized, which is the biggest
difference between the Group assignments and the stereo ‘Lin k’ option.
There are 4 groups in total. 1-device maximum
number of channels can be selected for each
group. T
he maximum number of channe ls is
determined by the device type you purchased.
Channels are set into one group which will be
differentiated by a color

volume slider in the main interface.
