    some Crest power amps and maybe others (?) offer this 8-pin accessory socket -- what uses does it have ? -- particularly for bass, or otherwise.

    crosssovers, or, a transformer for converting to balanced input signal, or, tubes for other signal processing prior to power amp stage ?

    Crest used to offer a series of accessories back in the early to mid 90's, like an input isolation transformer, a power limiter, a crossover (which took up both sockets), et al. QSC did, too, from the late 80's through the early 90's, for the octal sockets on Series One and Series Three amps.

    Crest's NexSys (a computer control/monitor system for power amps) system also used an interface module that plugged into the octal sockets.

    Yep. I have a QSC model 1700 with those and have the compressor modules in it. Neat idea. If I'm not mistaken, Mr. Peavey started that with his ugly old CS-800 amps. Feel free to correct me if I'm wrong!

    Somewhere in my cerebral cobwebs, that rings a bell. I think you're right.
