What kind of power supply/cord/cable works with this mixer?

Hi everybody,

Just bought this mixer from ebay, and the only this that isnt included is the power chord. So im trying to find out what kind of power supply i should get, to make it work. If you scroll down to the angled pictures on the bottom of the page, i see that on the back it says '12 vac' or '12 v ac' phantom. And on the top left of the mixer, it says '12 vac' again. Which one of these, is the true input for power? And is it possible to still buy AC adaptors for this mixer? Any help or knowledge is very much apreciated!

use 12v ac adaptor rated 2amp

Phantom power on an input socket is usually a separate DC input solely to power microphones through the XLR sockets on the rear. I would guess you need 12V AC across the two pins to power it up and the +/- are outputs from it's internal power supply.

The BNC socket on the top panel looks like an afterthought, possibly added to supply power to a radio mic receiver, see if it is directly linked to the pins on the rear panel.

Ok, thank you for the helpful info brian! When i get the mixer i'll check to see if the BNC socket is linked to true power input on the back of it. But if its not, then i will guess that it really dosnt do anything for me. How would i go about to find a power supply that fits into the socket on the back? It looks like a very custom made input just for this mixer, or at least i havent seen anything like this socket before? Does anyone know if this is a standardized power chord, or what this kind of socket is called?

Again, thank you very much everybody!

The sockets look a bit like a "cannon" xlr but don''t have the latch. Google the manufacturers site, they should quote the input socket types, all from the same manufacturer?

Or it could be the type used in Ham/CB microphone plugs although it lacks the locking ring. It could just be a 7-pin 270 degree DIN connector, an in-line socket type. If DOD are still around it would be worth checking with them. From the pin sizes I would guess they are only rated at about 2A so that gives you an idea of the power requirements.

just found these on ebay, looks like i got a perfect match with the seven pins!

In theory, could i just solder the "12vac pins" to a 12v AC power supply, and then fire this mixer up? Any suggestions to what i should solder the phanton-power/ground/+/- pins with?

EDIT: Ooops! Looks like its a female connection i need, what about this one? If i dettach it from the mount tubing?

Really need some creative inputs on how to make this cable on my own, does it look realistic?

IF it's a DIN connector, the one you want is this one: **broken link removed** which has the cable restraint and cover built in.

For now I would leave the phantom line disconnected, it's only needed when you use phantom powered microphones (balanced line electret/capcitance types). I would get it working normally first then see if there is continuity from the phantom line to BOTH sides of the microphone channel inputs.

It's just a guess that the AC input alone can power the mixer. Mixing consoles have quite often external DC supplies to keep transformers off. If it's so, the +/- DC pins will be most likely the main power supply (e.g. +/-18 or whatsoever). The AC input would be an auxilary supply.

P.S.: The "12 VAC" text at the BNC connector suggests that the AC voltage is for lighting only.

Great find Brian! thats a very big help for me, do you know to how solder the 7 pins? or do you have some references on how it could be done?

The "DIN-theory" has now officially been confirmed, stumpled upon this thread on 'fixya.com': https://www.fixya.com/support/t8268939-dod_mixer with a guy owned one of these mixers back in the day, and its still going strong up to this day, must mean that its a product of real quality. Read on what 'robbie335' is saying about a troubleshoot he has gone through to fix a hum. He gives priceless knowledge about the power supply!

The short answer is "fast and carefully", the back (inside the plug body) end of the pins is usualy hollow and you can poke the ends of connecting wires inside the hole before soldering them. There is usually a 'U' clamp on a metal tag inside the plug body that you can squeeze around the wires to stop them pulling away but it can be tricky to fold around the wires without just pinching them. I say 'fast' because the plastic used to hold the connections will melt if you let them get too hot while soldering. A trick is to buy a matching plug and insert it in the socket before soldering the wires. It too can be damaged by the heat but it will hold the pins steady for a while and buy you extra soldering time.

If you use the type I listed, don't forget to slide the plastic shell over the wires before you solder them! You can't fit it afterwards!

I'm not sure where in the World you are but DIN connectors are fairly standard and easily available. Make sure you get 7-pin 270 degree types, there is a 7 pin version with a center pin which will not fit.
