ADR Compex F760N-X racking info needed

Just picked up on of these units and Id like to get information on powering and 'racking' it. Anybody a fan of this unit?

you will need a 24V DC power supply, I used a 1 amp model, overkill I know but it works like a charm.

Here is the block diagram, I used this to wire mine up,

and if you want to get into it a bit more here are the schematics,

I did originally plan to rack mine up, and I think it would have just been able to fit in a 2RU rack case, but because I didn't have the tools to cut out the aluminium face plate, I just left it lying loose with pigtails. One thing I was planning on doing as well as racking it up, was to add a output stage for gain make up, because my F760X-N is lacking a output control, it has a peak limit threshold control instead. If you can do the metalwork yourself it is worth it, if not, it might be expensive, in the end that's what put me off racking it.

It is a great unit, I love it. Having the treshold on the peak limit is awesome, great for smashing room mic's. The compressor is great on vocals, guitars, snares, loops, room mics. A very handy piece of kit. Want to buy mine? heh

Thanks so much for the great info! I think I'll rack it but Im going to make space for another one. ; ) Which leads me to my next question. What do you want for yours? btw - my unit has the output control on it, was yours modified?

Hi Dean,

My Compex hasn't been modified, it is more likely a later series than the one you have. It looks like they replaced the ouptput pot with a peak limiter threshold pot, or it was a custom job. Also, mine is grey, like a Neve 51/V series console, not black like some others.

Is yours like this? Black Compex

Also, check your PM's
