Customer Testimonial

I have been working with Raul C. of your tech service group. I have found him and all of the other support people to be helpful and polite. I cannot imagine changing anything to your system as it is currently the best. I look forward to ordering several premium loud speakers in the near future.

Pros: Good amp for the money. Adds a lot of versatility with 4 channels. I run 2 channels out front and 2 for monitors. Combined with a 24 channel Phonic mixer the sound quality is very good. People noticed the sound improvement first time out, (I had been using a carvin & carvin combo). Cons: A little on the heavy side. Workmanship was poor, made in china, had to take the cover off and remove the pieces of leftover wire and components because they kept jamming one of the fans. Problem solved. Don't know the true rms power rating? With all that said, it's a good bang for the buck.
