The Xone:DB4 performance DJ mixer features a unique Quad FX Core DSP engine, providing four FX BPM Loop record engines with channel EQ filters. Other key features include multi-channel USB audio with MIDI, analogue and digital I/O, input source matrix, easy-to-read OLED display screen, and USB for recalling user set-ups.
The heart of the Xone:DB4 is the 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 five basic studio quality FX types optimised 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, whilst further effect tweaking can be performed using the global controllers in the FX master section. In addition to the FX, each channel has a built-in looper, with selectable loop length from 1/64 beat to 4 bars using the rotary encoder
Every music channel can select a multitude of available stereo audio sources, and each has a 3-band EQ that can be configured as standard asymmetric EQ (+6/-25dB), total Kill (+6dB/OFF with a 24dB/octave slope), or reconfigured as a High-Pass/Low-Pass filter system with adjustable resonance.
Other features include an OLED display that is clearly visible in bright sunlight, and which displays each channel FX selection and current BPM; a built-in, multi-channel USB2 soundcard allowing replay and recording from computer-based audio software for four stereo sends and four stereo returns; and a stylish lightweight aluminium chassis designed to make touring with the console easy.
Xone design manager Andy Rigby-Jones commented: “The Xone:DB4 is a truly ground-breaking mixer and by far the most advanced product that we have designed. Every feature has been meticulously researched with a view to offering DJ's ultimate creativity. Based on the iLive pro-touring FX system, we developed FX algorithms with BPM conscious parameters and tight spectral control, customised to perfectly fit the DJ environment. As the loops and FX are automatically synchronised to the tempo of the song, it is very easy to build some amazing grooves and soundscapes without problems of latency, low fidelity and the general hassle often associated with using software and laptops. The icing on the cake is the flexible input matrix, where any audio source can be selected on any or all of the channels. Different processing can be applied to the same track on separate channels and you can fade between them, or a phrase sampled in the looper of one channel can be added to the mix later in the track. Our digital design team has done an incredible job to ensure that this is one of the most innovative and exciting DJ mix tools to date.”
