Size doesn't matter, nor does price, as this exceptionally priced 2-channel mixer only takes up 10" by 12" of space, but has all the features you need for quality DJ work. As far as I/O, it offers 4 line, 2 convertible phono/line RCA inputs, a 1/4" mic input, 1/4" headphone output, as well as RCA Master and Record outputs. It even comes with an iPod friendly cable, so you have the choice of mixing traditional turntables, CD players, or the MP3s on your iPod. So what can you do with all that music? The 3-band rotary EQ per channel with -30db cuts, rotary gain channel control, Crossfader Curve and reverse controls, rotary cue, and PGM fader, let you mix, mash and spin your favorite tracks like a professional. And the VU meters with Master/Cue option help you stay on top of your levels.
