The Quad Stereo Channel (QSC) consists of four stereo channels, with a design based on the Channel module that, however, also borrows some concepts from the Group and the Master modules. The color scheme reflects the same routing of the modules: VCA (red), two effect sends (yellow and green), pan (pink), auxiliary input (purple), and main faders (white).

This peculiar feature set allows you to use the QSC within a standard CGM configuration, or as a standalone stereo mixer with mono effect sends.
