PPI DIN Cables, DIY? Need pinouts...

First is some background info, the question is at the bottom...

Hi folks, new here and glad I found this place. I'm into old school audio (I guess it's old school now ) - the equipment that was too expensive for me when I was graduating HS in early 90's. About 8 years ago I bought a PPI 5075DX amp and RCM-1000 control and have been looking for the DCX-1000 xover to go with it. I found one on eBay two years ago but when it arrived it was really trashed, of course opposite to what the seller said. It will power up (the red LED comes on) but case has a gash in it above the LCD display which is kind of flaky, plus the touch buttons don't work. It is controllable via the RCM-1000 however. At the time I called PPI but they told me they couldn't work on the old stuff anymore. I was too frustrated with the whole situation so it went on the shelf.

I "found" it the other day and figured I would be better off using this superb piece of equipment than leaving it on the shelf any longer. I'll leave it out of sight in the car and just control it with the RCM. Not what I originally had in mind but better than nothing.

So now to the question: does anyone have the pinouts for the PPI DIN plugs? I figured I would make my own DIN to RCA plugs with some real quality RCA connectors on the ends. I've searched and searched but can't find a pinout diagram for them. Would love any info or sources.

Thanks,
Patrick

If it is the 5 pin plug.From what i remember and looking at my old notes.Looking directly at the plug on the amp left to right.Pin 1 is -15volts,Pin 2 is left speaker,Pin 3 is ground,Pin 4 is right speaker,Pin 5 is +15volts.You can test the 1 and 5 pin with a meter and see if you get those voltages.you will use the 2,3,4 pins.

Sounds correct to my memory also. You can also test with a volt meter using the center pin #3 as ground as I am sure of that one without a doubt.

Good luck!

Thanks guys. I couldn't get any power readings out of the pins so I took it apart and looked at the board. Turns out pins 1 and 5 were never connected to anything. Only pins 2,3, and 4 are terminated on the board and pin 3 is common between all of them. Looks just the way you said it minus the power. Thanks!
