The only limiter on mine is called a volume control!
Alan, while I agree with what you have gleaned from Peavey, may I put in my two pennorth. According to website figures, a PV1500 at max output is giving approx 250w RMS ( 500 split between top and bottom) into speakers rated at 300w RMS. I personally feel that something a little bigger ( used circumspectly
) would be preferable, but the PV2600 is probably just a bit too big. I stand by my previous recommendation of the C-Mark/Thomann amp.
HOWEVER, if bi-amping was on the cards in the near future, I'd cheerfully accept the PV1500 as a contender, with possibly something a little bigger for the subs.
This is one of those topics where there are no "right" answers, but many which are not necessarily wrong.
I would hesitate to say that many suggestions on this topic were wrong, just that there are other options.
Edit: Alan's right about volume levels, that setup is quite big enough for so many venues. Only power crazed lunatics like myself appear to feel the need for more.
