This fully digital, high-performance DJ mixer features a unique Quad FX Core DSP engine, providing four FX bpm loop-record engines with channel EQ filters. Other features are multichannel USB audio with MIDI, analog and digital I/O, input source matrix, easy-to-read OLED display screen and USB for recalling user setups.
The quad FX core DSP engine enables each channel to have its own FX bank and bpm-detection system, which automatically adjusts all time-related FX and loops to the tempo of the music. There are five basic studio-quality FX types optimized for DJ use, comprising delays, reverbs, modulators, resonators and damage, plus each FX type has a patch library of different effect variations that can be assigned to the relevant control. Each FX bank has a dedicated expression control and a rotary pot to set the wet/dry level, while further effect tweaking can be performed using the global controllers in the FX master section.
Each channel has a built-in looper, with selectable loop length from 1/64 beat to four bars using the rotary encoder. No matter what loop length is selected, the Xone:DB4 will always record the maximum of four bars, so the loop can be expanded or shrunk at will. With an intuitive layout similar to the Xone:92, there are also two filter banks on either side of the main mix channels.
Each music channel can select any of the available stereo audio sources: analog line 1 through 4 (switchable to phono on 2 and 3), digital 1 through 4, or USB 1 through 4. Additionally, the mic/auxiliary channel can be routed through channel 1 for further processing.
Each music channel has a 3-band EQ that can be configured as standard asymmetric EQ (+6/-25 dB), total kill (+6 dB/off with a 24dB octave slope) or reconfigured as a highpass/lowpass filter system with adjustable resonance. The EQ knobs incorporate an illuminated pointer that changes color as a visual aid to show which type of equalization has been selected.
There is a mic/auxiliary input to the left of the main mixer section, providing 2-band EQ, gain, cue and mix level. This can also be routed to channel 1 if you wish to add FX to this channel. To the right of the main mixer is the master section, with main mix level, booth level and headphone monitoring system.
There is a built-in, multichannel USB2 soundcard allowing replay and recording from computer-based audio software for four stereo sends and four stereo returns. All controls (except mic and phones level) send MIDI data, but the mixer can double up as a MIDI controller via the MIDI Shift button, which allows the loop and FX selection controls to send MIDI data without changing the mixer settings.
Other features include assignable deck starts, crossfader and upfader curve controls, 13-point level metering, digital output, analog balanced outputs for main mix and booth, and a record output with adjustable level.
The Xone:DB4 is expected to be available in December 2010.
