C GF4 Expansion Module

The C GF4e is an optional expansion for the C GF4 group fader/distributor, and macro controller. The expansion adds 0–5V offset controls to channels one and three, and manual or CV-actuated mutes for all four channels. The manual mute switches offer both latching and momentary function. The C GF4e requires a core C GF4 module, and connects via an included ribbon cable.
