19" Rack Mount 4CH Professional Mixer

Bought this mixer thinking this was a good product. Took the mixer out of the box, turned it on to test drive it. As soon as I hit the Mic. talk over flip switch it breaks. Not even 15 minutes out of the box. Do not recommend anyone buy this cheaply made mixer. The effects are terrible and the EQ even worse. I consider this the worst mixer made after giving it a test run. I have put the mixer back in the box and am waiting for instructions to return it back for a full refund. Amazon has been good about this so far. This is not a professional made mixer, buy professional quality, not this.
