The power connector should be connected to the Eurorack power supply bus with the supplied ribbon cable.
Warning! Make sure that the polarization will be correct. The red stripe is -12V and should be oriented to the side indicated on the PCB.
All functions have a pair of pins on the backside. If you connect a signal here, it will be fed to the jack without the need to insert the cable on the front. If you insert a cable in the front-jack, it will get higher priority and deselect (break) the signal connected on the backside.
There are two additional pins for chaining two or more mixers together: “cap-in” and “line-in”. They are mixed together to the total mix but do not have any gain knobs. The cap-in signal has a DC-blocking capacitor and the line-in does not have a capacitor.
Warning! Make sure that you orientate your connectors the correct way when connecting to these pins. Ground is marked with GND-texts on the PCB and the other side is the signal pins.
|Level shifted signal out
|If you insert a cable in the front shifted jack, the signal to the shifted-out pin is broken.
|Mixed signal out
|If you insert a cable in the front mix jack, the signal to the mix-out pin is broken.
|Channel 6 in
|If you insert a cable in the front input 6 jack, the signal from the ch6-in pin is broken.
|Channel 5 in
|If you insert a cable in the front input 5 jack, the signal from the ch5-in pin is broken.
|Channel 4 in
|If you insert a cable in the front input 4 jack, the signal from the ch4-in pin is broken.
|Channel 3 in
|If you insert a cable in the front input 3 jack, the signal from the ch3-in pin is broken.
|Channel 2 in
|If you insert a cable in the front input 2 jack, the signal from the ch2-in pin is broken.
|Channel 1 in
|If you insert a cable in the front input 1 jack, the signal from the ch1-in pin is broken.
|Optional DC-blocking input.
|No break-jack-function. The signal is fed through a 10uF capacitor and becomes a part of the total mix.
|No break-jack-function. The signal is fed directly to the input and becomes a part of the total mix.
Converting to an AC-mixer
On the backside there are 6 small capacitor symbols. Each of these have a copper-wire in the middle that by default connects the two solder pads.
It is possible to cut this little copper wire for each of these 6 capacitor symbols and then solder six 0805 SMD 10uF capacitors there.
If you want to convert it back to a DC mixer again, you have to reverse the procedure by desoldering the caps and solder a new wire for each of the 6 capacitor symbols again.
Beware that this conversion voids your warranty!
