Power connector
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.
Pin header
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.
| Pin | Description | Break-jack-function |
| Shifted out | Level shifted signal out | If you insert a cable in the front shifted jack, the signal to the shifted-out pin is broken. |
| Mix out | Mixed signal out | If you insert a cable in the front mix jack, the signal to the mix-out pin is broken. |
| Ch6 in | Channel 6 in | If you insert a cable in the front input 6 jack, the signal from the ch6-in pin is broken. |
| Ch5 in | Channel 5 in | If you insert a cable in the front input 5 jack, the signal from the ch5-in pin is broken. |
| Ch4 in | Channel 4 in | If you insert a cable in the front input 4 jack, the signal from the ch4-in pin is broken. |
| Ch3 in | Channel 3 in | If you insert a cable in the front input 3 jack, the signal from the ch3-in pin is broken. |
| Ch2 in | Channel 2 in | If you insert a cable in the front input 2 jack, the signal from the ch2-in pin is broken. |
| Ch1 in | Channel 1 in | If you insert a cable in the front input 1 jack, the signal from the ch1-in pin is broken. |
| Cap in | Optional DC-blocking input. | No break-jack-function. The signal is fed through a 10uF capacitor and becomes a part of the total mix. |
| Line in | Optional input | 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!
