Unboxing Video for REQ231:

The Rockville REQ231 is an extremely high quality professional rack mountable equalizer. This is a 2 channel equalizer with 31 bands per channel. The main focus on this was sound quality and making it rugged and tough. We wanted to build a professional product that will instantly make a good speaker sound better, and after months of testing we know we did it!

This graphic EQ also has a low cut crossover filter switch, with status LED, that helps remove rumble from mics. Another great feature is the bypass switch, with LED indicator, which is very convenient when doing sound checks.

We added a sub output with frequency controls which is something that we see a need for. Many brands for some odd reason do not give you a sub output and sub controls. We made sure to include this important function.

If you want the best sounding EQ on the market at a great price, then we highly recommend you try out our REQ231. If you are unsatisfied with the quality we will give you a 90 day money back guarantee including return shipping!
