Three channel attenuator with inverting mode & mix output
The 6HP wide Oakley Sound Eurorack Multimix is highly useful mixer module that can be used to process both control voltages (CVs) and audio. It is based on the original 'Stooge' version of the Oakley Multimix for 5U.
The unit features three identical channels. Each one has its own level control pot and an invert switch. The pot controls the signal level running through that channel. The gain of the channel can be varied from 0 to 1.1 (+0.9dB) The invert switch when clicked to its downward position inverts the signal so positively going voltages become negatively going voltages. For example, +1V on the input can become -1V at the channels output. All output circuits are 'line driver' type and thus will not droop when loaded with any reasonable demand.
When the input socket of any channel is not used then the channel's output will become a fixed voltage source. The actual voltage is controlled by the pot and its polarity via the switch. Stable voltages from -5V to +5V can therefore be created.
The output of the third channel 'Out 3 / Mix' acts as a summing point for the other two channels should their own output sockets not be used. The output signal at the 'Out 3 / Mix' socket is then the mix of all three channels controlled by their respective pots and switches.
The module also features two output level LEDs. These monitor the signal level at the 'Out 3 / Mix' output socket. The 5V one lights when the signal exceeds +/-5V. The peak one lights when the output signal is getting near clipping, i.e., around +/-9V. Special circuitry is employed to ensure that either LED does not cause any power supply disturbances when they turn on or off.

These merchants probably sell this module. Huh?
