Good plan. Hearkening back to my "PA" daze... I used Peavey amps (CS-800s
and CS-400s) for my mains and was very happy with the DDT circuit. IIRC,
it is just a limiter but with an interesting design. Rather than linking
the gain reduction inversely to the input signal level, they monitor the
*output* of the amplifier itself to see when it has reached saturation
and reduce the gain to keep the amp right at or below it's "clip" point.

Since the clip point will change based on speaker impeadence and line
voltage, it was always able to "save" the amp & speakers from damage.
When the amps maximum output has been reached and gain is being reduced
to "keep it there", the DDT LED lights up to let you know it's working.
Also lets you know that even if you do turn it up more it won't get
louder..

I had nights where my CS-800's had those lights on almost constantly and
never lost a speaker or amp. :) It was loud... Real, fun, loud! :)

Here's a shot of my PA from the "good old days":

Ah, them were the days... ;)
