Strong, powerful and light.
It can handle anything that comes to it. Every since I sold my bass heads and bought this I haven't turned back since. It works in any situation audio wise. It will work for a DJ, PA system, guitar rig or a bass rig just to name a few. It can easily power any cabinet without strain. I run a 15-inch bass cabinet as of now and I have to be careful of not blowing my cabinet up! This thing actually is built strong! You can't go wrong with QSC, it is the best!

Nice power amplifier
The cost was the main reason for the purchase, however, I didn't know a enough about the manufacture and I read some reviews. Although some were helpful, I am glad I made the purchase. So far this amplifier is on point and it sounds awesome with Pyle mixer and Mackie speakers.

What's the Mystry math on these amplifers...
Works, seem to run fairly cool and quiet. Used for an out door backyard event. This wasn't my primary Amplifier, but it was driving (2) 3way 15in woofer speaker system. Not 300 watts of power...probably closer to 100 watts of power.

power hungery
This is one of 8 that I own and these are for my home stereo. I shop till I find a good price on one and I found this company on the internet and say the amp for sale so I made my offer and they accepted it. It arrived perfectly packaged and arrived in four days ,that really surprised me but the it was looking good and sounds excellent it get along with my other 7 amps so every thing turned out great, the only problem is that I want another one! But this it what I call a winner every thing turned out great and for that they get a 5 star ratting from me and I highly reccomend them if you are in the marget for amps and they have a wide variatof items so chek them out on e-net.Signed D.N.D

Amazing amp for someone like me that wants live stage ...
Amazing amp for someone like me that wants live stage sound and power in their living room. Ultra reliable and cool running like all the QSC stuff I've used before. Using one channel on this bad boy to power my BEHRINGER EUROLIVE VP1800S 18" sub. Any more power than this would be too much for home.

Avoid Dynamics Supply as seller.
Do not buy from Dynamics Supply. Amp appears to be used, box is destroyed, and arrived without a power cable.

Great amplifier so far
Great amplifier so far. I am using on my home sound system, so I haven't really tested it at high volume for an extended amount of time. Sound is clean and no distortion at mid range. The fan is a little louder than I am used too, but if using in a dj booth or on stage, would be a non factor. Once volume is turned up you can't really hear it. Overall a solid amp that gets the in home job done for my turntables.
