Excerpt: it definitely has quite a lot of power, but the cooling is sort of funky. it says front to back but in reality its back and front to side. it shootes the air out the sides of the unit so you have to make shure it can get the air out the unit if your rack mounting it. it dose get quite warm when using it at high power. for all those people saying its loud its only loud in a quiet area, you cant hear it when musics playing.
Pros: Easy To Use, Excellent Sound, Powerful, Simple And Cheap
Summary: One of the knobs might be off a notch, but it's really only apparent visually. The sound is a good quality and the input options are nice, and the output options have every type possible. The soft on feature keeps it from making noise when turning on, and no need to change the levels before turning on the next time you use it.
Summary: I purchased 2 of these power amps and love them! I read reviews and saw some said there was not enough power. If you set up power to ohms you will have no problem. I am running this amp to power 4 300 watt monitors and have NO PROBLEM! I also purchased the PQA 4100 and run 2 400 watt subs with NO PROBLEM! The fans are a little noisy ,but when the music starts you don't notice them. For the DJ or soundman who is on a budget..I highly recommend this product.
Summary: Let me start by saying that I was hesitant to buy this amp based on some reviews I have read, but the bottom line is if you buy this amp for the right reason you won't be disappointed. If you are looking for something for home theater purposes look somewhere else. This is a PA amp, it has a fan. That being said the fan is no louder than a standard pc fan, but if you were trying to use this for a home theater I could see how it could be distracting.
