Absolutely amazing mixer! 80 gig hard drive, holds upto 16 hours of recordings on 16 tracks. Built in effects. Multi tracking. Takes XLR and Phono. Phantom power. Has USB and PC connections. Used in studio, but is portable and can be used just as a mixer or you can record live. Also you can mix down to a stereo file on the mixer or transfer each individual track to your pc for track by track editing. Brilliant! Has a very comprehensive, in depth, easy to use manual which tells you everything and how to use it. Only ever used in studio, so is like new.
