I bet it is what we used to call a class AB amp. A class A amp pulls |
| 14 |
the same amount of power regardless of whether there is any sound but |
| 15 |
has very little distortion. A class B amp pulls only what is getting |
| 16 |
pushed to the speakers, less the drivers of course. Class B amps have a |
| 17 |
lot of distortion at low sound levels, that wasn't to good. So, someone |
| 18 |
came up with a cross between the two and got rid of the distortion but |
| 19 |
saved power at the same time. Most sound amps are Class AB but where in |
| 20 |
that cross depends on the maker. If you are really interested, here is |
| 21 |
a linky. |

I have built a few of these things. Getting that cross point can be |
| 26 |
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 |
| 29 |
is ready to make noise. lol Is it old or new? I can see a few watts |
| 30 |
even maybe 20 watts or so but almost 100 watts on standby. :/ |
