Came Damaged out of Box
This unit came damaged from the manufacturer. I don't know if it was a return that was shipped to me as new but it didn't work. I don't even know what was wrong with it. There was a dent like someone had opened the case up and switched the insides out. The music sounded terrible from this unit. Buy it from a reputable source. You know you can't buy everything from amazon. Repurchased from sweetwater and it was fine.

This amp is clean and runs very well and keeps cool while doing so.
This amp is very heavy and has a heavy startup draw when it is first turned on. My monster power device sees a significant drop in voltage when it is first turned on but it balances back out after a short while. The factory settings as they are preset; lacks sensitivity as in. You seem to get low volume per watt out of the box however, you can tweak this on the back panel with a small non-conductive tool. The sound reproduction is very accurate and clear. It has good mids and average low end. This amp is great for full-range systems that are stationary or a well built professional amp rack with wheels. It is much too heavy to be carrying around without one. If you are going to be moving this amplifier a lot I recommend purchasing the warranty anything this thing hit is going to either damage the unit or whatever it hits. Not recommended for beginners; it's too much of an investment to experiment with. Overall it has the power to be worth the investment. If you want something with better power and less weight I recommend a CVR amplifier that has less weight per watt ratio.

Great Product
I needed an amp for my Church. I did want or thought I needed to spend this much money on an amp. But someone that knew better than I strongly suggested I get this one. So glad I did. Just what we needed.

Certainly makes my BFM Tuba30 sub pack a serious wallop ...
Certainly makes my BFM Tuba30 sub pack a serious wallop. Not too much else to say here, since I haven't had a chance to use the bridged mode yet, and I handle all filtering and crossover stuff in my driverack.But it certainly puts some power through my subs, that's for dern sure.

QSC Is not responsible for hearing loss. Crank it up at your own risk!
Great product for the money.I'm in the market for another QSC amp, the next one will be RMX 2450A.The fan is a little noisy.. not bad. That's an easy fix tho.
