G – Group

The group is a stereo module that blends the signals coming from the channels linked to it (up to eight) and takes care of their signal routing.

The group “puts into practice” all the information defined by the controls of the channels: volume, effect send volume, stereo panning. In smaller setups, you can use it without a master module, using its local outputs as your system’s stereo outs.

It consists of three sections: the amplitude controls (white), and the two effect sends and returns (yellow and green).

Mono Send and Voltage-Controlled Stereo FX Return

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.

Assignable Stereo Outputs (Unbal? Pseudobal? Chedubal?)

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.

Mute Button

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.

Safe Solo Switch

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.

PFL Button

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.
