Fred,
Two things jumped out at me about the new QSC amps.
First, it's GREAT to have indicator lights on the back. Every time you're troubleshooting, you have to look at the connections while verifying that there's signal. With this QSC feature you can do it by yourself or without having to jump around!
But there's another thing that needs to be clarified.
The amplifier pairs are rated at 200 watts each, so you can get an 8 x 200 amplifier in a single rack unit space.
The average person will think that the 8 channel amp can output 1600 watts. But can it?
What makes the QSC MP-A series amplifiers noteworthy are several things. First, you can have channel 1 operate at 70 (or 100) volt and channel 2 operate at a low (4 or 8 ohm) impedance level. That’s noteworthy, but not completely unique. The second feature, dubbed FlexAmp technology allows the installer to allocate resources as required.
Very cool. I notice you're talking about channels 1 and 2, not all 8.
Essentially, take the pair of amplifier channels, (2 at 200 watts) and divide as needed. I can configure channel 1 to output 60 watts at 70 volts and channel 2 at 340 watts at the low impedance setting. It makes it really easy to designate the amount of power a zone or subsection of a zone receives. With 8 channels, I have four pairs of amplifiers available to manipulate, with all being different or all being the same.
Also pretty clear. You're now talking about 8 channels.
As long as the total power is 400 watts, you can manipulate as the job requires.
But I just realized that I might have totally misunderstood this.
I first thought uh-oh, we DO NOT have 1600 watts in one chassis, as the first paragraph seems to imply. The "total power" can only be 400 watts. But maybe you're talking 400 watts PER two-channel amp, so maybe the entire unit might be capable of 1600 watts.
Then again, you might have written it perfectly clearly but a copy editor might have messed it up to save a half inch of column space.
Could you clarify this?
