Those are serious amplifiers. A certain Big PA Company I used
to work for used those on sublows (each one drove four
cabinets of 4 * 18" drivers). There was a 10kW version, too.
I have two of the 'smaller' versions (7570) - a paltry
kilowatt apiece - which drive the bottom end on a small
rental PA. They 'fell off the back' of old MRI machines and
were about to be skipped! Stunningly heavy, which is why most
big amps nowadays are switchers.
A really interesting feature is the selectable
voltage-to-current capability, which allows some serious games
to be played around speaker resonances, although I'm sure that
wasn't the intention.
It's worth remembering that the parent company, Crown,
basically invented big-time rock'n'roll PA systems with their
classic DC-300 back in the late sixties. Its all their fault.
