yodominic Posted November 29, 2009 Share Posted November 29, 2009 I need some urgent advice, borrowed an EV P3000 from a friend of mine for a gig yesterday and used it to drive a single 4ohm rated sub on each side. Went to return the amp this morning and when switched on it powers ok with the fans running but the protection lights does not go off, opened the lid and cannot see anything obvious. Is there anything I could check? I need to get this fixed soon as he's got gigs coming next week-end. Any advice is greatly appreciated Link to comment Share on other sites More sharing options...
simonwest Posted November 29, 2009 Share Posted November 29, 2009 Is this the RL version of p3000 (i.e. P3000RL) or the analogue version? Link to comment Share on other sites More sharing options...
yodominic Posted November 29, 2009 Author Share Posted November 29, 2009 Is this the RL version of p3000 (i.e. P3000RL) or the analogue version? Regular P3000 Cheers Link to comment Share on other sites More sharing options...
Matt-onstage Posted November 29, 2009 Share Posted November 29, 2009 Hi, is the load still connected to the amp when it's in protect? Also, what sub we're you driving? Link to comment Share on other sites More sharing options...
yodominic Posted November 29, 2009 Author Share Posted November 29, 2009 Hi, is the load still connected to the amp when it's in protect? Also, what sub we're you driving? No load or input signal connected to the amp and when switched on the protection light does not go off. I was using them to drive 1 * b&c 21'' sub (1500w rated 4 ohm) on each side Link to comment Share on other sites More sharing options...
KevinE Posted November 29, 2009 Share Posted November 29, 2009 The P3000 is quite a complicated amp, if it's stuck in protect then it's faulty. How competent are you to fault-find at component level? Link to comment Share on other sites More sharing options...
aidso Posted November 29, 2009 Share Posted November 29, 2009 I agree with kevin on this one. There is quite a lot to the P series. Best bet is to ring shuttle sound and send it back to them. If you call them on 0208 646 7115 and ask for bruce or sean. They will sort you out. Link to comment Share on other sites More sharing options...
yodominic Posted November 30, 2009 Author Share Posted November 30, 2009 I have taken it to a guy who does amp repair and he said the output chips are blown on both channels, 24 per channel. Will find out the cost tomorrow. Link to comment Share on other sites More sharing options...
Rob_Beech Posted November 30, 2009 Share Posted November 30, 2009 Well, I find it difficult to believe that 24 per channel will have failed without something making them fail. I'm sure your amp man will find this out but I suspect that if this is the case then there will be something else that has caused this.

themadhippy Posted November 30, 2009 Share Posted November 30, 2009 Have you tried it with a load? Dont know about this particular amp,but on a few amps the protection light comes on if theres no load connected,even though the amp is working fine.

aidso Posted November 30, 2009 Share Posted November 30, 2009 no the protection light on the P series only lights when there is a fault. Link to comment Share on other sites More sharing options...
yodominic Posted November 30, 2009 Author Share Posted November 30, 2009 no the protection light on the P series only lights when there is a fault. That's what I'm told when the protection light comes ON the output channels are muted. also just found out that each output chip is rated 70w and costs between £4-£5.

Brian Posted December 1, 2009 Share Posted December 1, 2009 ...also just found out that each output chip is rated 70w and costs between £4-£5.Nope. They're rated at 250W and cost £2.12 each. Link to comment Share on other sites More sharing options...

They're rated at 250W and cost £2.12 each. I'm no expert in these things I'm just going by what I've been told. There are 24 chips per channel and each at 70W. In terms of cost I had someone else confirm that it could between £4 - £6 each. Link to comment Share on other sites More sharing options...
timtheenchanteruk Posted December 1, 2009 Share Posted December 1, 2009 Im thinking you may need a second opinion. Im in agreement that blowing all 24 is unliklely, especially if there is no underlying cause. Link to comment Share on other sites More sharing options...
