Sorry to be writing this as everything I have ever bought from Electro Market has been excellent. But I cannot give this system more than 1 star. The mixer creates a horrible hiss which can be heard, No matter what I do. Plug straight into the Sub woofer and the hiss goes away. For an aparant 800w system. It seriously lacks in power. The tops are very tinny..and even before anywhere near the limiter, The sound distorts. For a system that is nearly £500. I can't help but feel very disappointed. I'm afraid they're going to sit in the back of the garage. As any DJ knows..If you can't trust your equipment..It never gets used. Sorry. Graham.
