It looks like Allen and Heath may have accidentally leaked some info today on the DB4 mixer after teasing the dj market for the past few weeks. Its a 4 channel analogue mixer with a full sound card and built in digital fx. Think of the Rane 68 or a DJM-600 with a sound card. Hopefully clubs around the world will start installing hybrid mixers like this in every booth, so controller djs wont need to lug around sound cards! More info and another photo after the break. NEXT GENERATION DIGITAL DJ FX MIXER Quad FX Core The heart of the Xone:DB4 is the powerful Quad FX Core DSP engine, enabling 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 5 studio quality FX types optimised for DJ use – delays, reverbs, modulators, resonators and damage – plus each FX type has a patch library of different effect variations. Each FX bank has a dedicated expression control and a rotary pot to set the wet/dry level, whilst further tweaking can be performed using the global controllers in the FX master section. Looper Each channel has a built-in looper, with selectable loop length from 1/16 beat to 4 bars.The :DB4 will always record the full 4 bars, so the loop can be expanded or shrunk at will. Filters Xone:DB4 comes equipped with the Xone dual filter system. Source select Each music channel can select any of the available stereo music sources: Analogue Line 1-4 (switchable to Phono on 2-3), Digital 1-4 or USB 1-4. EQ / Filter Each music channel has a 3-band EQ that can be configured as standard asymmetric EQ (+6/-25dB), Isolator (+6dB/OFF with a 24dB/octave slope), or reconfigured as a High-Pass/Low-Pass filter system with adjustable resonance. EQ knob pointers change colour to show which type of equalization is active. Mic/Line Input The Mic/Line input has 2-band EQ, gain, cue and mix level. This can also be routed to channel 1 for adding FX. Integral Soundcard A built-in, high quality (24-bit / 96kHz), multi-channel, fully patchable USB2 soundcard allows replay and recording from audio software for 4 stereo sends and 4 stereo returns. http://www.djtechtools.com/2010/09/29/allen-heath-xone-db4/
