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.
X:LINK
X:LINK uses a standard RJ45 connector and distributes power and data allowing connection to X:LINK compatible devices, saving USB ports on your computer.
Looper
Each channel has a built-in looper, with selectable loop length from 1/16 beat to 4 bars. :DB4 will always record the full 4 bars, so the loop can be expanded or shrunk at will.
Filters
: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/-26dB), 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.
USB
User-defined settings such as meter mode, BPM range, USB audio routing scheme and display brightness can be saved to a USB key for recall on another :DB4.
MIDI control
All controls (except Mic and Phones level) send MIDI data and the mixer can double up as a MIDI controller via the MIDI shift button, allowing the Loop and FX selection controls to send MIDI data without changing the mixer settings.
Output Patchbay
Booth, record and phones - source selectable and level trim. Booth and main - phase and level trim controls.
High Visibility Display
The OLED display is clearly visible, even in bright sunlight, and displays channel FX selection and current BPM, as well as being an easy interface for the Menu setup functions.
Lightweight chassis
:DB4’s lightweight aluminium chassis is designed to make touring with the console easy.
