The group has two independent monophonic outputs and stereo inputs to create effect send/returns. (The mono output signal is the sum of all the channels’ send levels.) A CV over the stereo return level allows you to automate the effect section, like for gated reverbs, but also to use the stereo return as an auxiliary stereo channel.

Two outputs (left and right) provide either the local sum of all the channels connected to the group and their effect or just the wet sounds (for further parallel processing). A jumper on the back selects the behavior.

The mute button allows you to remove a group from the master sum with a click. The mute doesn’t affect the local outputs: in smaller systems, where a group is the output module, it prevents accidental muting; in larger setups, it keeps the local outputs active for creative parallel processing.

The switch lets you solo a “scene” of prepared channels set up through their solo-in-place buttons or switches. It can be seen as a mute group function that allows you to mute all the channels outside the solo scene with a click.

The PFL button routes the group to the master’s PFL section, allowing you to pre-listen the whole group when muted or with the fader all the way down.

Two peak LEDs show when the group is clipping. However, don’t be shy! You can clip the group on purpose and enhance your sound, either with a creamy saturation or a significant distortion.
