StereoMixer

3 Channel Stereo Mixer

‘StereoMixer’ is a three channel stereo mixer for modular synths.
Left mono channel is forwarded to right channel if nothing is plugged into right input.
It has an additional sum out wich sums the left and right signal pre main volume knob.
It also has two clipping LEDs wich light up when the pre main volume knob signal exceeds (+/-)10V.
The module is DC coupled therefore also suitable for mixing control voltage.
