M-166 6-ch Attenuverting Mixer module for Eurorack / Doepfer A100 system.

From the top down:
6x input jack + knob (ch1 – ch6)
output jack + polarity LEDs + out level knob

The M-166 is 6-channel attenuverting mixer.  Turning a level knob clockwise adds gain (output is non-inverted or ”positive”); turning a knob counter-clockwise both adds gain and inverts the signal (output is inverted or “negative”). The centered position of an input level knob is zero or “off.” A dedicated output knob sets the final level of the overall mix, with a maximum gain of 2x (+6dB).

Channel 6 is normalled to a DC bias voltage, meaning it can provide a DC level shift (or transposition) when nothing is plugged into jack 6.
The M-166 is DC coupled, meaning it can be used for either audio or CV.

Width: 8TE/ 8HP/ 40mm
Depth: 48mm /1,9″ max.
Current: 15mA
Power cable included

Double check power connection before powering your system please.
„Red strip“ means -12V connector side in Eurorack standards.
In some power distribution systems connector key can be reverted.
In this case cut connector key and plug power connector right way (with respect to red strip) or use different power cable appropriate to your power system.
