Amazing sound quality & functions!
First of all I want to say I am a professional Mobile DJ so I have exp. in this area for review. I picked up this mixer based on success of previous units from Numark and wanted something with a usb input for various devices. This is a perfect mixer for Mobile DJ's! Here's how mine is configured, channels 1 & 2 for Numark rack cd decks, channel 3 is usb for ipod backup, channel 4 is for Numark NS7FX. Amps are Crown, XLS 2000 & 1000 and this mixer gives these digital amp plenty of signal to drive them clean. The mic input has full EQ, cut, talkover and sounds great! Not one bad thing to say, this mixer will be in my next 2 rigs for sure!
