Denon's DN-X900 is a 4U rackmountable mobile/club DJ analog/digital matrix mixer with rock-solid construction and superb audio fidelity. The DN-X900 offers 4 coaxial digital inputs with 24-bit digital processing and 2 digital outputs that can feed your CDR burner or computer for recording purposes with a unique Track Mark ID function that allows you to make new track increments right from the mixer! 2 digital outputs are also provided in S/PDIF coaxial and TOSLINK formats. The DN-X900's 8 line and 3 phono inputs are assignable to any of 4 channels. This 8-channel input matrix routing gives you the freedom to move any source to any channel or even the same source to multiple channels for remixing. The DN-X900 features 4 smooth 60mm VCA channel faders for level control and a responsive 45mm VCA crossfader with contour adjustment. Independent pre-fader level meters allow you to optimize and match levels for each source, so you can be sure the transition crossfading between sources is smooth.

The DN-X900 also features 3-band EQ with full output kill, booth output with channel select, 2 mic inputs with talkover sensitivity and effects send/return with cue, dry/wet knob, and channel select.
