I bet it is what we used to call a class AB amp. A class A amp pulls the same amount of power regardless of whether there is any sound but has very little distortion. A class B amp pulls only what is getting pushed to the speakers, less the drivers of course. Class B amps have a lot of distortion at low sound levels, that wasn't to good. So, someone came up with a cross between the two and got rid of the distortion but saved power at the same time. Most sound amps are Class AB but where in that cross depends on the maker. If you are really interested, here is a linky. https://en.wikipedia.org/wiki/Electronic_amplifier#Class_B_and_AB I have built a few of these things. Getting that cross point can be fun. To much, smoke. To little, sounds like crap. lol 96 watts on standby. That doesn't sound like standing by as much as it is ready to make noise. lol Is it old or new? I can see a few watts even maybe 20 watts or so but almost 100 watts on standby. :/ Dale :-) :-) -- I am only responsible for what I said ...
