hello, I just bought a replacement din jack to replace the one removed from a mutron biphase. But because the wiring was disconnected.. I do not know the pinout of the din jack. the schematic shows 3 of the 5 connections to the pedal, but the others are not labeled.
anyone have the pinout or have a picture of the din jack from the back?
I have searched the internet with no luck, any help would be much appreciated.

be very specific, the din on the back of the bi-phase casing? or are we talking about the din on teh cable of teh opti-pedal for teh biphase or the footswitch unit itself. I can help. And are the original wires in it (wire colours?) or were they changed. Lorne

With the panel face down and open and separated from the base. On the main board, immediately to the left of the transformer fastened to the back and the spacer bar are 5 solder points in a row at the edge of the pcb. Starting from your left looking down with the din /back facing you and knob side down, the colours of the original wire, left to right are: yellow, green, orange/red, black, and, white (closest to teh mount brace and transformer. On the din socket with the notch on the left, bottom (top w knobs) of the socket, from the left white and black then yellow (left ) (on mine another yellow* with the Green, and slightly below the orange. So from the base of the unit, notch to the output side, From the bottom the circle is: yellow, green, orange, black, white. White is now immediately below the factory yellow wire. Screw to case one below and one above the locking din female socket. Two cool Mutron Mods: My yellow * is soldered onto the green at the din jack. It goes to a cv In jack. No ground needed. Jack is grounded by contact to the case. To the left 1/4" of the pcb line of 5 is a double row off three just above say 1" in from the pcb edge for a switch. I tap off the middle left to get the Cv for LFO1 out. I drilled and put in a jack for each, one above the other with lfo 1 on the bottom. Phaser out A & B are grey wires that go to the pcb. Sorry need a camera for that. I use the cv in to send S&H to my phaser (an old Oberheim trick from their guitar phaser pedal). It sounds very cool and rhythmic. I think I got the mod out of an old PAIA issue. cheers Lorne in Canada ( in memory of Kevin lightner, who also shared)

re 3 pins, the mutron biphase connects two different types of pedals. One set is simply two on off buttons and aground (3 wires) But if it has the opto continously variable pedal controller the ldr is a resistance loop for cv and that's what the other two wires are about. So it is no accident they use five pin connectors. If you go three pin you cannot use a pedal to control depth or lfo rates. Lorne in Canada
