Hi,

A friend of mine has a few EV P3000 amps. Occasionally, they will not come
out of protect at switch on, but if you keep trying they will, and will run
just fine after that. He brought me one a while ago to look at, but of
course it behaved itself perfectly for me, couldn't get it to go into
protect at all.. I did the usual cleaning everything and resetting the
bias. He has 3 or four of these amps now doing the same thing randomly, not
all the time. Anyone any experience with this fault and what causes it?



Cheers,


Gareth.

Have you spoken to the tech guys at Shuttlesound ? They're pretty helpful.

Yes I will do, they have been very helpful in the past. Its often good to
get input from the other side of the pond as well, and Usenet almost always
gets you more information than you were looking for or thought you needed.

This guy has actually brought one of the amps in now, its permanently in
protect, probably an output stage. Delving further it seems that he has a
variety of protect problems, not just the startup one I originally cited,
some will protect once a signal is outputted. He's been swapping his amps
around with his touring rig and an install, sometimes the amps go into
protect during a gig then mysteriously get working again.

Could be speaker cables / crossovers etc, but I wanted to find out if these
amps have any history of going into protect for no apparent reason.


Cheers,

We have a P3000 at the local vanue I do tech support for. No problems with that
one.
