INTRODUCTION TO THE XONE:23C
The Xone:23C is a high performance 2+2 channel VCA mixer designed
around the latest analogue circuitry, with microprocessor control of all
signal routing and featuring a high specification USB soundcard, incorporating
an X:LINK control interface port.
It is equipped with a version of the classic Xone filter system, a 3 band “Kill
Type” EQ Isolator, plus a send/return loop for external effects.
The crossfader curve has two settings, suitable for 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 grade 20dB of signal headroom, a separate booth monitor and
balanced XLR main outputs, (with an impressive +28dBu max level) the
Xone:23C is ideal for the DJ who requires a high quality compact mix tool
that easily interfaces with all leading DJ software.
Some key features of the Xone:23C:
• Four channel stereo 24bit/96kHz USB soundcard with X:LINK
• Classic Xone Voltage Controlled Filter system
• Up to four sources can be mixed simultaneously
• Kill-type three Band, full cut equalizer
• Dedicated booth Monitor
• Outputs on professional standard balanced XLR connectors
• Four inputs (2+2 stereo channels) with dual levels for phono/line inputs
• FX Send/Return loop
• Innofader crossfader option
• Accurate signal level monitoring with peak hold
• +28dBu maximum output level (balanced XLR)
• High internal headroom (+20dB) to prevent overload
• Universal voltage power supply (works anywhere in the World)
• Twin headphone sockets (1/4” and 3.5mm)
• Separate record output on RCA
• Negligible signal distortion (typically 0.01% at +10dBu output)
• UV sensitive ink screen for improved low light legibility
• Cue-mix control with illuminated Cue switches
• Crossfader curve switch
We wish you the same fun playing on it as we have had designing it!

INPUT CHANNEL CONTROLS
Input level controls
Adjust so the average
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 channel.
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 Sockets
Twin sockets for 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

effects unit is not connected
Filter Frequency
Sets the cut off frequency of
the VCF filter
Microphone EQ

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.
