A Group module sums the signals of up to eight connected Channel modules plus their aux sends and also controls the master volume of the stereo sum by using the large "fader" knob.
The yellow and green sections are the both auxiliaries, with their elements being (from top to bottom):
- Mono Send. Emits the sum of all "yellow" or "green" aux sends of all connected channels.
- Two dual mono returns which turn into a stereo return (L+R) when both sockets are in use.
- manual gain control, or when using a CV it becomes its attenuator.
CV input of the stereo return VCA. Accepts 0-5V or 0-10V levels.
The large potentiometer is the "fader" which controls the Group's output volume (i.e. all stereo sums of Channels and the aux returns). LED visualize the post fader level.
The output signals L+R are emitted at the two very top sockets, marked in white. Alternatively the sockets can emit the stereo sum of the aux returns, which is jumper selectable.
At the bottom there are three more functions and their according LEDs:
Contained is a pair of Link Cables for connecting up to four Channel modules to one Group.
