Four-channel master mixer for audio signals and control voltages with master-level control, channel on/o ff switches with status-LEDs as well as independent voltage controllable input volumes and panorama positions. Master volume control with dual stereo headphone outputs (switchable pre/post master control). Switchable 440 hz tuning aid. Voltage ranges 0-10 volts, panorama control (set at center position) needs -5/+5 for full left/right range. The module is DC-coupled (except headphone outputs) to use it e.g. as a quad input/dual output mixer for control voltages. DC coupling can be defeated via jumpers on the PCB. The module has the original Moog Console Panel form factor.
