INTRODUCTION TO THE XONE:23
The Xone:23 is a high performance 2+2 channel VCA mixer designed around
the latest analogue circuitry featuring microprocessor control of all signal
routing.
It is equipped with a version of the famous Xone filter system, a 3 band EQ
Isolator, plus a send/return loop for external effects.
The crossfader curve has two settings, suitable for either blending or beat
matching, or a more aggressive curve for scratching. For ultimate crossfader
performance the mixer can also be equipped with a custom Innofader,
available from your nearest Allen & Heath stockist, (part number
004-504JIT).
With a studio standard 20dB of signal headroom, a separate booth monitor
and balanced XLR main outputs, (with an impressive +28dBu max level) the
Xone:23 is perfect for the DJ who requires a high quality compact mix tool.
Key features of the Xone:23 are:
 2+2 stereo channels with dual levels for phono/line inputs
 Up to 4 sources can be mixed simultaneously
 3 Band full cut equalizer
 Voltage Controlled Filter system
 Send/Return loop for external FX
 Accurate signal level monitoring with peak hold
 Main mix outputs on professional balanced XLR connectors
 Dedicated local monitor (booth monitor)
 Pro standard headroom (+20dB) to prevent overload
 +28dBu maximum output level (balanced XLR)
 Low audio distortion (typically 0.01% at +10dBu output)
 Dedicated record output
 Crossfader curve switch
 Innofader crossfader option
 Cue mix control with illuminated Cue switches
 UV sensitive ink screen for improved low light legibility
 Universal voltage power supply (works anywhere in the World)
We wish you the same fun playing on it as we have had designing it!

INPUT CHANNEL CONTROLS
Input level controls
Adjust so that the aver-
age music level lights the
0 LED on the meter, with
the beats lighting the +3
to +6 LED. Turn down if
the +10 Red LED is illu-
minated. Each input has
its own separate level
control, so make sure to
fully turn down
(anticlockwise) the input
you don’t want feeding
into the mix.
3-Band full kill EQ
Turn anti-clockwise to
kill a frequency band or
clockwise to boost.
If all controls are fully anti
-clockwise the signal will
be muted
Channel Fader
VCA fader allows you to progressively
raise or lower the channel signal in the
mix.
For best signal-to-noise ratio, mix with
the fader at or near the top of its travel
Filter/FX SND switch
Pressing this switch sends
the channel signal to the
VCF filter section, and
to the external effects
SND output
Channel Cue switch
Pressing this switch
allows you to monitor
the channel signal with
the fader fully down
before bringing it into the
mix.

MASTER CONTROLS
Master output Level
Sets the signal level to the
main XLR mix output
Monitor output Level
Sets the signal level for the
local monitor (booth) output
Headphone level
Sets the level of the head-
phone output.
Warning! Very high level can
cause hearing damage!
Crossfader curve switch
Push to the left for a progressive fader
response, useful for blending between
tracks. Push to the right for a sharper
response, more suitable for scratching
Cue/Mix Control
When set to Cue, nothing will
be sent to the headphone
output unless a channel Cue is
activated. When set to Mix,
the main mix will always be
sent to the headphones. In the
centre position the Cue signal
and the main mix are summed
together.
Crossfader
This is used to “fade” the signal level between
the two channels, and its response is set us-
ing the curve switch. When the crossfader is
fully over to the left only the music from
channel 1 will be heard, and when fully to the
right only channel 2. When in the centre the
music from both channels will be heard in
equal proportion.
Headphone Socket
Accepts both 1/4” and 3.5mm
plugs. Use a good quality set
with an impedance between 25
- 70 Ohms.

MIC AND FILTER CONTROLS
Filter Resonance control
Changes the “Q” or sharpness
of the VCF.
Mild will give a smooth filter
sound, Wild will make the
filter sound more pronounced
(sharper “Q”)
Filter type select
HPF - allows signals above the
cut-off frequency to pass.
LPF - allows signals below the
cut-off frequency to pass
FX loop on switch
Press this switch to activate
the external effect loop. Leave
switched off if an external
effects unit is not connected
Filter Frequency
Sets the cut off frequency of
the VCF filter
Microphone EQ
2 band EQ for adjusting the
tonal balance of the DJ mic
Microphone input
Professional XLR balanced mic
input. Use a low impedance
dynamic hypercardioid Mic for
best results.
Microphone Level
Adjusts the signal level of the
mic input. If you are not using
the mic, turn to minimum to
prevent noise pick up.
