Behringer say "The ultra-compact XENYX QX602MP3 2-bus mixer’s 6 Inputs (2 mic, 2 stereo) allow you to effortlessly achieve premium-quality sound, thanks to its 2 onboard studio-grade XENYX Mic Preamps with available Phantom Power, and our ultra-musical “British” channel EQs. Add to this a high-performance MP3 player for accessing audio files from a USB stick, and a built-in 24-bit, stereo multi-FX processor with presets for studio-class reverb and delay, and the QX602MP3 becomes an incredibly versatile – and amazingly affordable mixer!"

I say that this is a little gem of a mixer that packs in loads of fetaures that keep it incredibly flexible with a great reverb/ delay sound and takes outboard effects well. A great little investment. This is a used unit, but with only a couple of paint dings/ scuffs. Everything works as it ought to and has been thoroughly tested for quality assurance.
