Soundcraft Spirit 'Live' 24/4/2 PSU

Postby infiniteloop » Sun Oct 16, 2011 11:13 am

I have a Soundcraft Spirit 'Live' 24/4/2 desk that is producing some fairly nasty hum & buzz rendering the desk currently unusable. I've been (somewhat) reliably informed that the most likely culprit is the PSU which is a DCP100

Is it possible to use a Soundcraft DCP150 PSU with this desk..? They seem to be easier to track down & less costly than a DCP 100 or DCP 125

My techy dude will be having a look at the desk tomorrow & I'm just wondering if it would more cost effective picking up a 2nd hand DCP 150 than repairing the current DCP 100

Cheers in advance..

Dont bother trying to repair a power supply buddy... your best off looking on ebay for a used one or buying a new one @ trade cost.

If you get stuck send us a PM as i have an account with Soundcraft

I wouldn't agree with Tim - it doesn't sound like an expensive fault although, if a replacement is less than £40-50, it probably isn't worth paying someone to fix. If it was mine, I'd fix it myself.

A similar thread on Blue Room suggests they all use the same voltages (+/-17V plus 48V for phantom power), so a higher-rated supply would be fine. Unfortunately Soundcraft don't have info on the DCP-100 - too old for their online spec sheets! Try ringing them, perhaps?

Repair might be cheap if you're the repairer. If you need to pay someone to do the repair, costs could rack up quickly though, which might be overkill for a rather old desk.

It would be worth trying replacing all the electrolytic capacitors in the P/S they are the most likely suspects for the fault you mention, and caps are cheap and relatively easy to replace.

Many thanks for the replies, it's much appreciated. Unfortunately my knowledge of electronics is such that I could write it all down on the back of a stamp & there would still be enough room left for a small novel.! The guy who repairs my gear is very very good & also a mate, he doesn't foresee any issues with the repair, although if I could track down a 2nd PSU at a decent price I'd still get it as a backup.

Why did it break though.... that is what you need to find out

Welllll... if it's the smoothing capacitors, as has been suggested, then they can just die after a while of use, it's not uncommon. I've had to replace these in Spirit desks, and then they're good for another 3000 hours or whatever. I'd not say it's a particular cause for concern, electrolytic capacitors just don't last forever.

Quite so, electros have a limited life. It is worth making sure any replacements are 105 degree temp rated as they will last longer than the normal 85 degree caps. It doesnt cost much extra for top quality caps! Your repair dude should know all about this kind of thing!

Remebr any second hand P/S is going to be on the way to the same issues.

Good luck.

I bought the desk in this condition cheap as chips (£20) great cosmetically & fully flightcased so figured I didn't have much to lose even if I couldn't get it back up and running, the flightcase alone is probably worth 3 times what I paid for the lot. It's currently with my repairs guy so I should know the final outcome shortly

Sounds like a bargain! At that price, a few quid on repairs is definitely justified.
