I have a Crest Pro 5200 that seems to have problems with low supply voltage.

I had problems with it power cycling at a gig so I put it on the bench, 1 channel driven into 6 ohms with 120v supply it will go all day. If I drop the supply voltage to about 107 v it will cut out with that load.

It is the only Pro 200 series amp I own so I don't have another to compare it to but I am thinking it should be able to run on voltages lower then that.

Anyone have some experience with these amps?

Thanks

Supply range is 100-132V AC for the north american version which is is written in the manual, but I saved you the time by reading it for you.

Once you go below 115 volts you are going to encounter abnormal behaviour. I am uncertain why you would want the amplifier to operate well on 107 volts.
