Pro Amp for Home Audio(?)

[soiset]

A good friend of mine is third in line receiving a pile of Pro-Audio gear, passed along from people who didn't know what it was, but didn't throw it away. He has approached me about going halfsies for whatever I can get via ebay/craigslist. Most notable to me among the equipment is a Crown MacroTech 1200 amp. Would anyone suggest using this for home stereo or home theater applications? Its apparently VERY powerful. I was thinking it might be great for biamping lows or running subs. Whatchoo think?

Specs:
Macro-Tech 1200
Stereo mode (both channels driven):
675 watts into 2 ohms.
480 watts into 4 ohms.
310 watts into 8 ohms.
Bridge-Mono mode:
1300 watts into 4 ohms.
970 watts into 8 ohms.
620 watts into 16 ohms.

Frequency Response: ±0.1 dB from 20 Hz to 20 kHz at 1
watt (see Figure 6.7).
Phase Response: ±10 degrees from 10 Hz to 20 kHz at 1
watt (see Figure 6.10).
Signal-to-Noise Ratio: 20 Hz to 20 kHz: Better than
100 dB below full bandwidth power. A-weighted: Better
than 105 dB below full bandwidth power.
Total Harmonic Distortion (THD): Less than 0.05% at
full bandwidth power from 20 Hz to 1 kHz increasing linearly
to 0.1% at 20 kHz.
Intermodulation Distortion (IMD): (60 Hz, 7 kHz) Less
than 0.05% from 163 milliwatts to full bandwidth power.
Damping Factor: Greater than 1,000 from 10 Hz to 400
Hz (see Figure 6.8).
Crosstalk: See Figures 6.11,

It would be great for running a passive subwoofer.

+1 on mark's comment. Not sure when that model was built, but most of the vintage Crown gear is bullet proof

I'm reading the manual now. http://www.crownaudio.com/pdf/legacy/130252.pdf

Seems it is THX certified. I'm beginning to think this thing may really be a keeper for my ultimate home theater (you know, the one that consists only of AutoCad pixels). I am running a pair of PSW1200's now, and I have separated the stock amp from one of these for structural reasons. I have the stock amp mounted in a Polk S4 speaker cabinet (fits quite nicely), so I have made that sub "passive" now with an external amp.

I am sure that the two db12's in the PSW1200's could use a LOT more power than the stock amps provide, and it looks like this amp could provide it. I never have bothered figuring out if the 12's were wired in series or parallel. My guess is that they are two 4 ohm models wired in series, which I think would mean that I could re-wire them in parallel and use the available 675 watts at 2 ohms available from the Crown for both subs.

That, and this whole balanced/unbalanced input thing. Gotta figure that out.

Balanced is beneficial for long IC runs, mainly.

crown are just good and they are well trusted in throughout the pro audio industry

as far as i know

That would be an awesome sub amp. Would drive my Tumult quite nicely:D
