Welcome to the XONE:62
The Allen & Heath XONE:62 presents a unique combination of performance tools for the
professional DJ in a stylish and solidly built club format. Above all, it features sound quality second
to none. XONE:62 has been designed and constructed using the same rigorous standards we
apply to our large format professional consoles used and respected by top engineers throughout
the world. We have had great fun designing this new range. We are sure you will get even more
enjoyment using it.
XONE:62 provides 6 dual stereo channels, with A and B inputs on each, two offering mic inputs,
adding up to a massive 10 stereo and 2 microphone inputs. A full range of connectors means that
you can connect up to 4 turntables, 2 mics, CD players, MD players, drum machines, samplers, and
pretty much anything else you might want to bring into the mix.
The more bands of EQ you have, the more creative you can get with your mix. That is why we give
you 4 EQ controls rather than the usual 3. Each band has a safe +6dB boost and a massive –
26dB of cut, enough to creatively shape your sound well beyond normal EQ range, and without
overloading your system. Punch the effect in or out using the EQ on switch.
Channels 3 to 6 can be assigned to either side of the high spec Penny & Giles VCA crossfader.
This controls the audio using a DC voltage meaning that it can take a huge amount of punishment
without the bangs and crackles that inevitably creep in on regular audio faders. It is easily
removable from the top panel for quick replacement should it become worn. The curve can be
switched to either dipped response, ideal for seamless beat mixing, or to dipless better suited to
scratch or cut mixing.
Unique to XONE, two stereo state variable Voltage Controlled Filters provide the DJ with a new
level of live performance creativity. These are very similar to those found on classic analogue
synths but benefit from modern, quiet and stable technology. Use these to sweep the sound by
accentuating or cutting frequencies from 100Hz to 20kHz. The 3 filter types HPF, BPF and LPF
can be combined to create many more amazing effects. A large Resonance control changes the
‘Q’ or sharpness of the filter effect from subtle to extreme. Each VCF has its own in/out switch.
Combined with the extensive output and monitoring features, colour coded indicators, stylish layout
and clear graphics visible in all lighting situations, you have an unbeatable performance console
equally at home in dance clubs, home set-ups, live venues, and on the road.

XONE:62 User Guide
The XONE:62 Application
This diagram shows an example hook-up to demonstrate how the XONE:62 can be connected in a
typical DJ application. Note that you do not need to connect the channels in the order shown, also
that the connector types on the equipment you connect to may be different to that shown. Use
cables appropriate to your application. Please read Plugging Up The System before connecting
to your equipment. The following describes how the console is used in this example application:
Microphone sources: The DJ microphone is plugged into CH1. A second mic is
plugged into CH2, typically for MC or guest announcements. These signals route to the
mix output and headphones. They are not routed through the crossfader, nor to the
booth monitor, so avoiding potential acoustic feedback.
Background music source: A CD player plugs into CH2 line input as an alternative to
the second microphone. This provides operator free background music when the DJ is
not performing, typically during early evening walk in or intermission. The music routes
to the mix output and is not affected by the crossfader.
Mix music sources: CH3 and CH4 are used for the mix music sources. Both a
turntable and a CD deck are plugged into each, one for each side of the crossfader. The
turntable magnetic cartridges plug into the RIAA equipped phono inputs, the CD into the
line inputs. The required source is selected using the channel source select switch. This
gives the DJ the choice of vinyl or CD mixing, or cross mixing between the two. CH3
and 4 are conveniently centred on the crossfader, ideal for easy XY crossfading.
Drum machine: It is increasingly popular for the DJ to cut in additional sources over
the mix. A drum machine provides a creative instrument, ideal for enhancing the beat
and bass line. This is shown plugged into CH5 stereo line input. It can be assigned to
either side of the crossfader or direct to the mix as required.
Sampler effects: The stereo Aux send is used to feed selected channels to an external
effects unit such as a sampler or echo device. This is typically set pre-fader so that the
effect can be set up while the channel fader is down. The sampler output is returned into
CH6 line input and becomes another creative source that can be added to the mix, either
direct or through the crossfader.
Mix outputs: These outputs feed the house PA system to provide quality sound to the
dance floor. The connections are balanced pro level +4dBu to feed long cable runs to
the amplifier system. They may plug into system processors such as protection limiters,
EQ and crossovers which in turn connect to the amplifiers.
Mono output: This output provides a mono sum of the left and right mix that follows the
master fader. This is shown connected to a sound-to-light controller that provides
lighting effects in time with the music. Alternatively, the mono output could be connected
to a sub bass amplifier system to supplement left and right satellite speakers, or to a
mono zone speaker system.
Recording the show: A dedicated music only stereo output connects to a recorder
such as the MD shown to record the performance. Typically the mic signals are not
recorded. The signal is not affected by the master mix control.
Booth monitor: A stereo speaker system provides the DJ with a music only local
monitor. This can be checked or worked in mono if required, or muted if the DJ wishes
to check the main PA sound or work with headphones only.
Headphones: Closed ear stereo headphones are recommended allowing the DJ to
check and cue the music sources. Split-cue keeps the program in one ear while cueing
with the other to synchronise the beat before introducing the source into the mix.

XONE:62 User Guide
Quick Start We recommend that you read through all sections of this User Guide before starting. However, we
provide these notes so that you can plug up and experiment with sounds from your XONE:62
immediately if you prefer to read the full guide later. Please note that you should first read and
understand the Important Safety Instructions printed at the beginning of this guide. The following
simple procedure requires a CD player and headphones. Alternatively you can connect a pair of
turntables and start mixing right away. Please read the rest of this guide before connecting to your
amplifier and speaker systems.
Set all controls to their starting condition. Set all
and BOOTH MONITOR controls minimum. Set PAN and EQ
controls to their detented centre position. Set all switches to
their up position.
2 Plug in a CD player. This provides a good stereo audio
source as a starting point. Plug into CH3 line input as shown.
Do not use the phono input for CD or other line level sources as
this is intended for turntables with magnetic cartridges requiring
RIAA equalisation.
Plug in the headphones.
Plug into the top panel
PHONES socket. Use the best headphones you can afford for
your application. We recommend the professional grade
closed-ear type of 30 to 100ohms impedance, and with ¼” TRS
jack plug. Avoid using the popular mini jack to ¼” adapters as
these can quickly prove unreliable.
4 Connect AC mains power. Check first that the correct
mains lead with sealed plug suitable for your local supply has
been provided with your console. Plug into the AC MAINS IN
socket making sure the connector is pressed fully in.
5 Switch the console on. Press the rear panel ON/OFF
switch. Check that the green and red XY leds above the
crossfader both light. You may notice that the console meters
flash briefly. This is normal during power up.
6 Select the line source. Press the CH3 source select
switch. This lights red to indicate that the line source is
7 Adjust the channel gain. Start the CD player. Adjust
CH3 GAIN control until the average music level lights the
channel meter green 0 led with loudest peaks lighting the yellow
+6 led. If no signal is present check that the music source is
playing and the correct input is selected.
. Reduce GAIN if the red PK Led lights. This indicator
is a warning that the signal is approaching clipping and
that distortion may result if the level increases further.
XONE:62 User Guide
8 Check the sound using the Cue system. With the music
playing press the large CUE switch. The switch lights as well
as the master CUE led to show that the cue monitor is active.
The channel signal is now sent to the headphones. Slowly turn
up the headphones level control until you hear the music.
Avoid listening to loud headphones levels for long
periods as this may damage your hearing.
The channel signal is now displayed on the main monitor
meters giving you finer control in setting the gain. Note that the
cue system lets you monitor the channel signals pre-fader. In
other words you can check or cue any source before you raise
its fader to bring it into the mix.
9 Route the signal to the main Mix output. Release the
CUE switch. The CUE led turns off and the headphones and
monitor meters go quiet. Raise CH3 fader to its top ‘0’ position.
Raise the MIX master rotary control to maximum. With the
XFADE ON switch in its up position the signal is routed direct to
the mix. The signal is now displayed on the main meters at the
same level as the channel meter. The level is now the same
throughout the console signal path, as set by the channel gain
control. This is the ideal setting with meters averaging 0dB so
giving the best signal-to-noise performance while maintaining
plenty of headroom to avoid clipping.
10 Listen to the main MIX output. The music should be
heard in the headphones. If not, then check that the AUX
switch is released and that no CUE switches are selected.
11 Check the effect of the Stereo EQ. Press CH3 EQ ON
switch. This lights to show that the signal is routed through the
equaliser. Now try the effect of each of the 4 frequency bands.
The EQ is designed for creative live performance control and
provides a safe +6dB boost and a massive –26dB cut.
Experiment with cutting rather than boosting frequencies to
create dramatic effects. These can be punched in or out using
the EQ ON switch.
12 Route through the Crossfader. Press XFADE ON to
route the signal through the crossfader rather than direct to the
mix. The green X led lights indicating that the channel is
assigned to the left (X) side of the crossfader. Press the XY
switch to assign the signal to the right (Y) side. The yellow Y
led lights. Note the green X and yellow Y led above the
crossfader to help you see where the channels are routed.
Using the Crossfader.
This lets you fade between
signals routed to either side, typically to fade smoothly into a
new music track or to creatively layer sounds when scratch or
cut mixing. Experiment further by connecting two CD decks or
turntables and assigning one to X, the other to Y. Use XFADE
PAN to adjust the balance between the left and right mix, either
to correct an imbalance or as an effect in its own right.
XONE:62 User Guide
14 Changing the crossfader curve. The little switch to the
left of the crossfader sets which curve is active. In the normal
up position the signal dips by 6dB at the middle position for
smooth fading between tracks. Press the switch for a dipless
response where the signal starts to dip only once the fader has
passed the mid position. This is better suited to scratch or cut
mixing where you layer the sounds.
15 Crossfader mixing. At this point you may wish to plug
in a pair of turntables and experiment with DJ mixing. Plug into
CH3 and CH4 phono inputs if your turntables require RIAA
equalisation. If not, plug into the line inputs. Remember to
connect the turntable earth leads to the console chassis earth
terminal. Use CUE to set up the channel gain as you did in
step 7. Route CH3 to X and CH4 to Y of the crossfader.
16 Adding VCF filter effects. Each side of the crossfader
features a stereo Voltage Controlled Filter which presents the
DJ with a unique set of live performance tools to create subtle
or startling tonal effects. With the signal assigned to the Y side
of the crossfader, and the crossfader moved fully to the right,
the music is routed to the mix and should be heard on the
headphones. Press the Y FILTER switch to route the signal
through the analogue filter section. The blue led lights to show
that the filter is active. Check that the large LPF switch is
illuminated indicating that the power up default lo-pass filter
type is active. The sound should change to a rumbling bass
line with higher frequencies removed.
Sweep the filter frequency.
Turn the VCF control
clockwise and you should progressively hear higher audio
frequencies returning to the mix. This control sweeps the effect
from low to high frequency.
Adjust the filter resonance.
Slowly turn the
RESONANCE control clockwise as you sweep the frequency
and you should hear the ‘Q’ or ‘sharpness’ of the effect
changing from subtle to drastic as the roll-off knee sharpens
and frequency boost is added.
Increasing resonance boosts a narrow band of
selected frequencies. Make sure you reduce the channel
gain if the red peak meters start to flash.
19 Change the filter type. Press one or any combination of
the large HPF, BPF and LPF filter type switches to experiment
with different performance effects. For example pressing HPF
and LPF together produces a notch effect. Once you are
familiar with the creative power of these filters you can apply
them to your performance. More information is available later.

Gain and Operating Levels
It is most important that the system gain and level settings are correctly set. It is well known that
many DJs push the gain to maximum with meters peaking hard in the belief that they are getting the
best from the system. THIS IS NOT THE CASE ! The best can only be achieved if the system
levels are set within the normal operating range and not allowed to peak. Peaking simply results in
signal distortion, not more volume. It is the specification of the amplifier / speaker system that sets
the maximum volume that can be achieved, not the console. The human ear too can fool the
operator into believing that more volume is needed. Be careful as this is in fact a warning that
hearing damage will result if high listening levels are maintained. Remember that it is the QUALITY
of the sound that pleases the ear, not the VOLUME.
The diagram above illustrates the operating
range of the audio signal.
music the signal should range between –5 and +5
on the meters with average around 0dB. This
allows enough HEADROOM for unexpected
peaks before the signal hits its maximum
CLIPPING voltage and distorts. It also achieves
the best SIGNAL-TO-NOISE-RATIO by keeping
the signal well above the residual NOISE FLOOR
(system hiss). The DYNAMIC RANGE is the
maximum signal swing available between the
residual noise floor and clipping. The XONE:62
provides a massive 110dB dynamic range.
Use the GAIN TRIM 1 to match the input source
to the normal operating level of the console. Adjust
this so that the CHANNEL METER 4 averages
0dB with loudest moments reading +6. Press the
CUE SWITCH 3 to listen to the signal on
headphones and check the level on the expanded
range MAIN METERS 9 . Adjust the CHANNEL
FADER 5 and MASTER FADER 6 so that they
normally operate in the shaded area near the top.
Make sure the amplifier/speaker system has been
correctly calibrated for the loudest volume required
at the fader top position. Boosting the EQ 2 also
adds gain to the system. Reduce by turning back
the GAIN TRIM 1 if the meter red peak leds flash.
Adjust the HEADPHONES 8 and BOOTH 7
monitor controls for safe listening levels.
XONE:62 User Guide
A final note … The human ear is a remarkable
organ with the ability to compress or ‘shut down’
when sound levels become too high. Do not
interprete this natural response as a reason to turn
the system volume up further ! As the session
wears on ear fatigue may set in, and the speaker
cones may become hot so reducing the
effectiveness of the system and listeners to gain any
benefit from increased volume.
Connecting Mains Power
Read the SAFETY INSTRUCTIONS printed at the
front of this User Guide and on the rear panel. Check
that the correct mains lead with moulded plug has
been supplied with your console. The power supply
accepts mains voltages within the range 100-240V
without changing any fuses or settings.
It is standard practice to turn connected power
amplifiers down or off before switching the console on
or off. This prevents any audible switch-on thumps.
Ensure that the IEC mains plug is pressed fully into the
rear panel socket before switching on.
The connection to earth (ground) in an audio system is important for two reasons:
SAFETY - To protect the operator from high voltage electric shock, and
AUDIO PERFORMANCE - To minimise the effect of earth (ground)
loops which result in audible hum and buzz, and to shield the audio
signals from interference.
For safety it is important that all equipment earths are connected to mains earth so that exposed
metal parts are prevented from carrying high voltage which can injure or even kill the operator. It is
recommended that the system engineer check the continuity of the safety earth from all points in
the system including microphone bodies, turntable chassis, equipment cases, and so on.
The same earth is also used to shield audio cables from external interference such as the hum
fields associated with power transformers, lighting dimmer buzz, and computer radiation. Problems
arise when the signal sees more than one path to mains earth. An ‘earth loop’ (ground loop) results
causing current to flow between the different earth paths. This condition is usually detected as a
mains frequency audible hum or buzz.
To ensure safe and trouble-free operation we recommend the following:
Have your mains system checked by a qualified electrician. If the supply earthing is solid to
start with you are less likely to experience problems.
Do not remove the earth connection from the console mains plug. The console chassis is
connected to mains earth through the power cable to ensure your safety. Audio 0V is
connected to the console chassis internally. If problems are encountered with earth loops
operate the audio ‘ground lift’ switches on connected equipment accordingly, or disconnect the
cable screens at one end, usually at the destination.
Make sure that turntables are correctly earthed. A chassis earth terminal is provided on the
console rear panel to connect to turntable earth straps.
Use low impedance sources such as microphones and line level equipment rated at 200
ohms or less to reduce susceptibility to interference. The console outputs are designed to
operate at very low impedance to minimise interference problems.
Use balanced connections for microphones and mix output as these provide further
immunity by cancelling out interference that may be picked up on long cable runs. To connect
an unbalanced source to a balanced console input, link the cold input (XLR pin 3 or jack ring) to
0V earth (XLR pin 1 or jack sleeve) at the console. To connect a balanced XLR output to
unbalanced equipment, link the cold output to 0V earth at the console.
Use good quality cables and connectors and check for correct wiring and reliable solder
joints. Allow sufficient cable loop to prevent damage through stretching.
If you are not sure ... Contact your service agent or local Allen & Heath dealer for advice.

Plugging Up The System
The XONE:62 uses professional grade 3 pin XLR, 1/4" TRS jack and RCA PHONO sockets. To
ensure best performance, we recommend that you use high quality audio cables and connectors,
and take time to check for reliable and accurate cable assembly. It is well known that many audio
system failures are due to faulty interconnecting leads. The following mating plugs may be used to
connect audio signals to the console:
The input and output XLR connectors are 3 wire differentially balanced. These have 3 connector
pins: Pin 1 = ground (screen), Pin 2 = signal hot (+), Pin 3 = signal cold (-).
The jack sockets are the 3 pole TRS type. These are wired to work with both the balanced TRS or
the unbalanced 2 pole TS type plugs without cable modification. The sockets have 3 connector
pins: Inputs and outputs are Tip = signal hot (+), Ring = signal cold (-), Sleeve = ground (screen).
Headphones are Tip = left, Ring = right, Sleeve = ground.
The RCA phono connectors are the 2 wire unbalanced type typical of those found on equipment
such as CD players, turntables and domestic amplifiers.
Avoid reversing + and - on balanced connections as this will result in out of phase signals (reverse
polarity) which may cause signal cancellation effects.
Where long cables runs are required, balanced interconnections should be used. However,
interconnections between more affordable 2-wire (signal, ground) unbalanced equipment and the
console are unlikely to cause problems if the cables are kept short. Refer to the following diagram
for unbalanced to balanced connections.
Dealing with Ground Loops, Buzz and Interference
For optimum performance all audio signals should be referenced to a solid, noise-free ground
(earth) point, frequently referred to as the ‘star point’ or ‘clean earth’.
A ground loop is created when the signal has more than one path to ground. Should you
experience hum or buzz caused by ground loops, check first that each piece of equipment has its
own separate path to ground. If so, operate ground lift switches on connected equipment in
accordance with the instruction manuals. Alternatively disconnect the cable screen at the
destination end only. This breaks the offending loop while still maintaining the signal shielding
down the length of the cable.
WARNING For your safety do not remove the earth (ground) connection in the power
lead of the console or connected equipment.
To avoid interference pickup keep audio cables away from mains power units and cables, thyristor
dimmer units or computer equipment. Where this cannot be avoided, cross the cables at right
angles to minimise interference.

1 CH1-2 MIC input. Balanced XLR. Plug in a
DJ, guest or announcement microphone here. Use
good quality low impedance dynamic mics such as
those specifically designed for vocals. Do not use
high impedance or unbalanced microphones, or
condenser types which require phantom power.
Use professional grade balanced cables wired as
CABLE D . Use the best cable and connectors you
can afford as these are typically subject to intense
use and abuse in the club environment.
2 CH1-2 LINE input. Unbalanced TRS jacks.
Connect mono or stereo line level sources which do
not need to route through the crossfader. For a
mono source plug into the L/M input only. For a
stereo source plug the left source into the L/M input,
and right into the R input. These are 3-pole TRS
sockets which can accept balanced or unbalanced
TRS or TS jack sources. Depending on the source
connector type, use CABLE B C E or G . To
connect RCA phono jack sources you can use the
standard CABLE A with RCA to jack adapters, or
custom make as required.
3 CH3-6 LINE input. RCA phono. Connect
stereo line level music sources such as CD, MD,
DAT, drum machines, keyboards or other
instruments. Do not connect turntables which
require RIAA equalisation. Use CABLE A .
Alternatively, you can connect to jack sources using
this cable with RCA to jack adapters. Avoid using
low grade cables such as those often supplied with
domestic equipment as these can quickly prove
unreliable in use.
4 CH3-6 PHONO input. RCA phono. Plug in
turntables with magnetic cartridges requiring RIAA
equalisation. For non-RIAA turntables plug into the
LINE input instead. Do not plug in line level sources
to the phono inputs as these will overload the
preamp and cause severe high level distortion. Use
high grade versions of CABLE A .
5 Chassis earth terminal. Two screw terminals
are provided for connecting the earth straps from
turntables. This connection earths the metal parts
of the turntable to reduce hum, buzz or similar
audible noise getting into the system.
6 RECORD output. RCA phono. This provides
a music only output not affected by the main mix
fader. Connect to a stereo recorder such as MD,
DAT or cassette to record the show. Use CABLE A
with or without adapters, or a custom cable,
depending on the recorder connector type.
XONE:62 User Guide
7 AUX output. Impedance balanced TRS jacks.
Depending on the application of the Aux mix this
stereo line level output can be used to feed
samplers and other effects units, an additional
monitor, zone or recorder. Connect to balanced or
unbalanced equipment using CABLE B C F or
H . To connect RCA phono jack sources you can
use the standard CABLE A with RCA to jack
adapters, or custom make as required.
8 MONO output. Impedance balanced TRS
jack. This output sums the post-fader left and right
mix signals to provide a feed to mono or sub bass
amplifier systems, sound-to-light controllers and so
on. Connect to balanced or unbalanced equipment
using CABLE B C F or H .
9 BOOTH output. Impedance balanced TRS
jacks. Provides a line level music only stereo feed
to the DJ local monitor amplifier system. It is not
affected by the master fader or cue system.
Connect to balanced or unbalanced equipment
using CABLE B C F or H .
10 MIX output. Balanced XLR. This is the main
output that feeds the house PA system. Plug into
the house processor/amplifier system using
balanced CABLE D or E . It is not usual for
unbalanced equipment to be used here.
11 AC MAINS input. IEC cable with moulded
mains plug suitable for the local supply. Please
refer to Connecting Mains Power.
12 USER connector. This 9-pin D-type female
connector is not wired as standard. It is provided for
custom wiring of special modifications that may be
required for a specific application. This work, if
required, should be planned and carried out by
competent installation or service personnel.
13 HEADPHONES output. Stereo TRS jack.
Plug in stereo headphones fitted with a stereo ¼”
jack. Avoid using mini-jack to ¼” jack adapters as
these can prove unreliable with continuous use.
Use closed-ear headphones that provide maximum
acoustic isolation when cueing your sources. We
recommend that you use high quality headphones
rated between 30 to 100 ohms impedance. 8 ohm
headphones are not recommended.
WARNING To avoid damage to your
hearing do not drive headphones at high
listening levels for long periods of time. Start
with the level control set to minimum and raise it
until a comfortable listening level is achieved.
Input Channel
These controls adjust the level and tone of each source before they are mixed. Six input
channels are provided. Each has two inputs. CH 1 and 2 are used for microphone or
alternative stereo line source. They provide corrective source equalisation. CH 3 to 6
are used for the turntables or alternative stereo music sources and can be routed
through the crossfader and VCF effects stage. These provide effective equalisation to
creatively shape the sound during performance.
1 AUX send. Adjusts the level of the channel
signal to the stereo Aux output. Turn fully
anticlockwise to turn the signal off, fully clockwise
for a maximum +6dB boost. The normal ‘0’ position
is marked.
2 PRE switch. With the switch in its up position
the signal to the Aux mix is sourced post-fader.
This means that the Aux send follows the channel
fader movements. Press the switch to source the
send pre-fader. Set in this way the fader has no
affect on the Aux level.
Post-fade sends are typically used to send channel
signals to effects devices such as reverb
processors. The amount of signal sent to the device
follows the fader level. The processed (wet) signal
returned to the mix elsewhere is therefore in
proportion to the direct (dry) signal regardless of
fader position. This could, for example, be used to
add ambience to the DJ or guest vocal mic.
Other post-fade uses include special recording or
zone feeds. Note that the channel post-fade sends
do not follow the crossfader setting. Use the
XFADE Aux send instead if the level should be
affected by the crossfader.
Pre-fade sends are typically used to feed monitor
speakers such as stage foldback. Here, it is
important that fader changes made to balance the
house mix do not affect the monitor levels.
When working with a sampler effects device you
could use either post or pre setting. If you wish to
cue the sampler effect before raising the source
fader into the mix then set it pre-fade. Use the
sampler return channel fader to bring up or remove
the effect from the mix.
You can use the Aux mix to cue your music
when beat or cut mixing. Set all sends pre-fade and
select the headphones monitor AUX switch to listen
to the selected channels. This lets you listen to the
effect of mixing the sources or matching the beat
before you bring it into the house mix.
XONE:62 User Guide
3 MIC/LINE switch. CH1 and 2 are the ‘MIC’
channels. They can select either the XLR
microphone input or the alternative jack stereo line
input. In the up position MIC is selected, indicated
by the green led. When pressed, LINE is selected,
indicated by the led changing colour to red.
4 PHONO/LINE switch. CH3 to 6 are the
‘MUSIC’ channels. In the up position the switch
selects the PHONO input, indicated by the green
led. This input provides standard RIAA equalisation
for high quality magnetic cartridge turntables. When
pressed, LINE is selected, indicated by the led
changing colour to red. Use this to select non-RIAA
or alternative stereo music sources.
5 GAIN control. Adjusts the input sensitivity of
the channel to match the connected source to the
console 0dB operating level. This provides a 20dB
range with continuous adjustment for line level
signals from –10dBu to +10dBu, –40dBu to –20dBu
for mics, or to match a wide range of RIAA turntable
cartridges. Use the channel meter and Cue system
to correctly set the gain.
Reduce GAIN if the channel meter red PK
led flashes.
6 MIC EQ. The CH1 and 2 equaliser is different
to the CH3-6 equaliser. It provides a powerful tool
to adjust the tonal quality of the sound to correct
source problems such as microphone
characteristics, proximity effect, noise and feedback,
or to adjust the overall ‘feel’. Start with the EQ
controls set to their mid (flat) position. Then adjust
to achieve the desired sound. Take time to
experiment with these controls.
The XONE:62 equaliser provides separate tone
control over four frequency bands. The frequencies
in each band may be boosted or cut by up to 15dB.
The centre flat position is detented for quick
HI Turn this control clockwise to boost and
anticlockwise to cut the high (treble) frequencies.
This has a shelving response with all frequencies
above the 10kHz turning point affected. Note that
frequencies below 10kHz are affected by a
decreasing amount. Use HI boost to brighten up the
sound by adding sparkle, and cut to reduce source
hiss and ambient high frequency pickup, or to limit
or lift the high response of vocal mics.
MID 1 Turn clockwise to boost and anticlockwise to
cut the higher mid frequencies. This has a bell
shaped peak/dip response that has maximum effect
at 2.5kHz. Boosting can enhance the intelligibility of
vocals. On the other hand, some situations may
require cutting to notch out a ringing frequency so
increasing gain before feedback.
XONE:62 User Guide
MID 2 This is similar to MID 1 but affects the lower
mid frequencies centred at 250Hz. Boosting can
enhance the warmth of the sound while cutting can
reduce the unpleasant resonant or boomy effects.
LO This is similar to the shelving HI control but
affects the low (bass) frequencies below the 100Hz
turning point. Note that frequencies above 100Hz
are affected but by a decreasing amount. Use LO
boost to enhance low end punch, or cut to reduce
source hum and rumble, or to remove the bassy
sound of vocal mic proximity effect.
7 MUSIC EQ. CH3-6 feature a unique four band
equaliser similar to CH1 and 2 but providing a very
different function. While the centre frequencies are
the same, The range of boost and cut is different to
better suit music mixing. This provides the DJ with
effective equalisation to creatively alter and shape
the sound during live performance rather than
simply correct source problems. Pre-recorded
music does not usually need corrective EQ. This
type of equaliser is known as ‘asymmetric’ because
the amount of boost and cut is not the same. Boost
is restricted to a safe +6dB to highlight selected
sounds while preventing system overload through
heavy use. Cut on the other hand, is increased to a
huge –26dB to completely suck out affected
frequencies dramatically changing the effect. Use
cut rather than boost to create your dramatic
performance effects.
8 EQ ON switch. For CH1 and 2 use this to
compare the original and equalised sound. For
CH3-6 use this to punch the performance effect in
and out. The switch illuminates when the EQ is on.
9 CUE switch. Press this large switch to listen to
the pre-fader channel signal in the headphones and
to display its signal on the main meters. This does
not affect the house mix or booth speakers and lets
you audition the signal to cue a track before adding
it to the mix. Cue is post-EQ for mic but pre-EQ for
music channels so that you do not lose your
reference when beat mixing, regardless of the EQ
effect. The switch cap illuminates so that you can
see at a glance which channel is cued.
10 Channel meter. A 4 led meter bar always
shows the presence of the pre-fader channel signal.
Adjust the gain control for normal music averaging
0dB with loudest moments reaching +6. Reduce
the gain if the red PK led flashes.
11 Channel fader. A 60mm stereo fader adjusts
the signal level from off to the normal ‘0’ top
position. This allows smooth fade ins and a visual
indication of its contribution to the mix. The fader
does not affect the pre-fade Aux sends.
Crossfader and VCF
The crossfader is the one feature that instantly sets the DJ mixer apart from a conventional mixer. It is applied to
the stereo music channels and lets you smoothly fade from one track into another using a single fader. It is also
used as a creative performance tool to layer or interact between two sounds when cut or scratch mixing . It is
fully assignable from each music channel and can be easily replaced if it becomes damaged or worn through
exceptional mechanical operation. The high quality Penny & Giles type is used on the model.
The XONE:62 is unique in being the first DJ mixer to include an analogue voltage controlled filter (VCF) section.
These filters provide live performance tools far more powerful than any equaliser or kill switch. They produce the
same warm analog resonant frequency sweeping sound as made popular by well known classic analogue
synthesisers, but using the latest high performance technology for quiet, stable operation.
1 VCA Crossfader. The XONE:62 uses four
high performance voltage controlled amplifiers
(VCA), a pair for each side of the stereo crossfader.
The robust 45mm fader produces a DC control
voltage which determines the signal level of the
VCAs. The voltage is filtered to prevent any audible
noise, clicks or scratchiness resulting should the
fader track become worn. This benefit would not be
possible if the signal were routed through a
conventional audio fader.
2 XY Indicators. A colour coded led above each
side of the crossfader helps you visually check
which channel is routed to which side, green for X,
yellow for Y.
Dip Curve With the switch in its normal up position
each signal is attenuated by 6dB in the middle
position. This means that there is no overall change
in level as the two similar signals mix, ideal for
seamless beat mixing when fading smoothly from
one track to another.
Cut Curve When the switch is pressed each signal
has no attenuation in the middle position.
Attenuation starts as the fader moves beyond the
middle. This gives a more dramatic response better
suited to cut or scratch mixing, layering different
sounds, or to emphasis a mix.
3 Crossfader Curve. The VCA system allows
that the fader law (curve) to be easily changed to
suit the style of mixing. Set the tamperproof
underpanel CURVE switch to the position required.
Two standard curves are available. Experiment with
both to understand their effect on the sound:
XONE:62 User Guide
4 XFADE ON. In the up position the music signal
is routed directly to the mix. Press to route the
signal through the crossfader.
5 XY. To route to the left (X) side make sure the
switch is in its up position. Press to route to the
right (Y) side. Either the green X led or yellow Y led
lights to show which side is routed. Both leds are
off if the signal is not routed through the crossfader.
6 XFADE PAN. Adjust to change the balance
between the left and right crossfader output signals.
Use this to correct an imbalance in the stereo
output, or as a dynamic performance effect. For
normal performance make sure the PAN control is
in its detented centre position.
7 XFADE to AUX send. This controls sends the
output of the crossfader to the stereo Aux mix. For
example, you could send the DJ music mix to a
monitor, zone, effect or special recording feed.
Replacing the Crossfader
The crossfader on a DJ mixer is heavily used and
can suffer considerable wear and tear. The audio
design using VCAs prevents clicks and scratchiness
as the fader wears. However, the movement can
become mechanically stiff or sloppy in time, or
become ingrained with dirt. Should this be the case
the fader may need replacement.
The XONE:62 crossfader is removable and can
easily be replaced in a few minutes. Make sure you
order the correct Penny & Giles version from your
Allen & Heath dealer: XONE2:XFADER
The VCF Filters
A voltage controlled filter is an audio filter whose
cut-off frequency is altered by a DC control voltage
rather than a variable resistor. This produces a
much wider operating range and more control over
the filter response to create unlimited combinations
of tonal effect.
Each X and Y side of the crossfader is provided with
its own stereo VCF. Each can be switched in or out,
and each has its own frequency sweep control. The
filter type and resonance effect are globally selected
affecting both filters simultaneously.
8 FILTER ON switch. Each X and Y filter has its
own ON switch. The blue led lights when the filter is
switched on. The signal is not affected by the filter if
the switch is in its off position. Use this to punch the
filter effect in or out.
9 VCF SWEEP control. Each X and Y filter has
its own frequency sweep control to adjust the cut-off
point anywhere from low to high frequency.
Rotating the control during performance produces
the dynamic sweeping effects desired by performing
DJs. These large soft touch controls are positioned
either side of the crossfader for convenient live
operation. Separate controls for X and Y mean that
the effect can be applied to each track
independently and faded in as the crossfader is
operated. Note that the filter type and resonance
setting apply to both filters and are not
independently controlled.
10 RESONANCE control. Adjust this to change
the ‘Q’ or ‘sharpness’ of the filters. This affects how
they respond around the cut-off frequency. At the
minimum MILD setting the filters have a gentle rolloff ‘knee’ giving a subtle, smooth response. At the
clockwise WILD setting they produce a resonant
feedback boost around cut-off resulting in some
very dramatic performance effects. The sound
varies according to the filter type selected. To avoid
unexpected results it is best to start experimenting
with RESONANCE set to a low position.
Use a medium size cross-point (Pozidriv)
screwdriver to undo and remove the two outer
screws on the crossfader plate. Do not remove the
inner screws. Lift the crossfader assembly up and
away from the console panel. Unplug the cable
from the old crossfader and plug in the new
assembly. Check that the connector is correctly
aligned and pushed on. Replace the assembly
making sure the cable faces the left side of the
console. Refit the screws and test operation.
XONE:62 User Guide
High RESONANCE settings can result in
significant boost of selected frequencies.
Reduce the channel GAIN if the signal levels
increase enough to light the red PK leds in the
output meters. Failure to do this may result in
system overload and distortion.
Filter Type Select
The filters are ‘state variable’. This means that they
provide three simultaneous filter types, high-pass,
band-pass and low-pass. Three large illuminated
switches select which type is active. You can press
any combination together to create different
response types such as ‘notch’ and an interesting
‘all-pass’ effect. The switches are ‘soft switched’ for
live performance, meaning that the audio signal is
ramped between filter states to prevent audible
clicks. The selected type affects both X and Y
Note that the last selected type is lost when power
is removed from the console. The LPF is always
selected when power is applied.
The graphs below show the effect on the audio
frequency response for the three filter types. The
range of sweep from low to high frequency is shown
together with the effect of adjusting RESONANCE
(one frequency with several resonance settings
The vertical scale shows the amount of cut or boost
around the normal 0dB operating level. The
horizontal scale shows the change in frequency
from low (bass) to high (treble).
12 BPF. Press this switch to select the bandpass filter. Frequencies above and below the cut-off
point are removed leaving just a narrow band of
sound. Sweep VCF around its mid position to affect
lead sounds such as keyboard and vocals.
☺ Tip.
Try picking out individual sounds such as
vocals and mixing them into the beat and bass of
the opposite track to create a whole new mix. Add a
little resonance to the BPF to lift the sound out of
the mix.
In addition to the three basic filter types you can
experiment with new effects by selecting
combinations of switches together. Press and
release the switches together. They illuminate to
show which filter types are active. For example:
Try sweeping the LPF back to a low
setting to keep the beat and energy going while
talking over the mix. Try also punching in the filter
and sweeping it back from high to low in time with
the beat. Punch it out at the start of the next bar.
Try switching the HPF in with VCF set fully
clockwise at highest frequency, then gradually
sweeping the frequency back to minimum. This can
create an atmosphere of anticipation as the dance
floor awaits the power of the beat to kick in.
☺ Tip.
☺ Tip.
13 LPF. Press this switch to select the low-pass
filter. Frequencies above the cut-off point are
removed. The cut-off point is adjusted using the
VCF control. At minimum only sub bass remains.
Sweep clockwise to gradually introduce the bass
line followed by higher frequencies into the mix.
11 HPF. Press this switch to select the high-pass
filter. Frequencies below the cut-off point are
removed. The cut-off point is adjusted using the
large VCF control. At minimum little effect is heard
as only sub bass frequencies are removed. Sweep
clockwise to gradually remove the bass line followed
by the higher frequencies. The highest frequency is
limited to 10kHz as little useful material is heard
beyond this.
HPF+LPF = NOTCH. Used with low settings of
RESONANCE you get a phasing effect. Try
sweeping the effect across the frequency range.
HPF+BPF+LPF = ALL PASS. A surprising effect
considering that all frequencies are ‘passed’.
However, the filter type interaction around the cutoff point creates an interesting effect that varies
from subtle to dramatic depending on the
RESONANCE setting.
☺ Tip.
Take some time to experiment with the
filters before ‘going live’

Master Mix and Monitor System
The XONE:62 provides a stereo main mix output with fader control and balanced XLR
connections to drive the house PA amplifier system. It also provides a mono output that
sums the left and right mix signals to feed an additional mono zone, sub bass or soundto-light controller. You can make a music only recording by connecting to the
independent record output. Full DJ monitoring facilities are available with independent
headphones and booth monitors, together with stereo metering system. Every signal
can be checked individually or within any mix, ideal for system setup and performance
cueing. Facilities such as Mono and Split-Cue switching are well suited to the way the
professional DJ works.
1 MIX MASTER. A rotary master control adjusts
the output level feeding the house PA. This is a
stereo control which adjusts the left and right signals
at the same time. It affects the stereo mix and
mono outputs. Note that it does not affect the
record and booth outputs. The maximum position
represents unity (0dB) gain. If you find yourself
normally setting the control in the lower part of its
travel then the connected equipment may be too
sensitive for the operating level of the console. With
the control set to its maximum position adjust the
input level trim of connected equipment for the
loudest level allowed.
In a club or similar installation strict sound
level and noise regulations may apply. Check
that your system levels are set up to comply.
2 MIX / MONITOR METERS. A pair of meter bars
displays the level of the selected headphones
monitor source in. This is either the main mix, the
Aux mix or Cue. When SPLIT CUE is selected the
left meter displays the active CUE signal, the right
displays PRG (program), both in mono.
Each meter has 12 leds to indicate signal levels
from a low –20dB. Green and yellow leds indicate
normal operating levels. The top red led lights at
+8dB still providing a healthy 13dB before clipping.
Meter ‘0’ represents +4dBu at the XLR outputs. The
meters are peak responding with a fast attack and
are therefore able to display fast transients
accurately. The top five leds are ‘peak hold’ which
means that the highest remains lit for a short time
after the signal has gone. This makes it easier to
keep track of the highest levels.
3 CUE indicator. A large red led lights when a
channel CUE is active. This indicates that the
selected channel CUE signal is heard in the
headphones and displayed on the monitor meters.
It is important to use CUE to set the channel gains
correctly to maintain the wide dynamic range
achievable with this console. Reduce the gain if the
red PK leds flash.
XONE:62 User Guide
4 HEADPHONES level control. Adjusts the level
of the signal in the stereo headphones. This does
not affect the level of the local monitor.
WARNING Some headphones are more
sensitive than others and can produce higher
output levels. To avoid damage to your hearing
start with the level control at minimum and turn
up only as much as is needed to maintain
comfortable listening level. Do not drive
headphones at high listening levels for long
periods of time.
5 SPLIT-CUE switch. Press this switch to
change the way CUE operates. Normally, pressing
a channel CUE switch overrides both left and right
monitor program signals with the stereo cue signal.
With the switch pressed, CUE overrides just the left
channel leaving the program in the right channel.
The left monitor meter displays the cue signal, right
displays program. This is invaluable in club mixing
where the main program should remain audible
while cueing other channels ready to bring them into
the mix. It is very useful when beat mixing using
headphones. Note that Cue does not affect the
main output or booth monitor.
6 AUX switch. In the normal up position the
headphones and meters monitor the post-fade main
mix. Press the switch to select the stereo Aux mix
as the headphones monitor source. Note that this
does not affect the main output or booth monitor.
☺ Tip.
Use split-CUE to match the beat between
two tracks when beat mixing, or check the effect
before cut mixing. Alternatively, you can select Aux
and raise the sends on the two channels to give you
a pre-fade stereo PREVIEW of the mix which does
not affect the main output. In this way you can hear
exactly how it will sound in the main mix before you
raise the channel faders or flip the crossfader. Use
the Aux send controls as your preview faders.
Pressing any CUE switch will override the preview.
The DJ uses the headphones to check the mic and
music sources and to cue tracks ready to bring them
into the mix. The headphones isolates the dance
floor sound from the DJ and also prevents the
audience hearing the monitor.
The BOOTH Monitor
The DJ uses the booth monitor to reinforce the
music level in his booth so that he can ‘feel’ and
interact with the beat. This provides an independent
music only monitor that is not affected by the main
Mix master control. It is also not affected by the Aux
or Cue monitor sources. To avoid acoustic
feedback the microphone signals are not routed to
the booth monitor.
8 MONO switch. Sums the left and right monitor
signals together so that the selected stereo source
can be checked in mono. Use this to check for
mono compatibility and phase problems, especially
important in dance floor and recording applications.
A drop in level or loss of low frequencies when
pressed indicates reversed phase between the left
and right signals. Alternatively, you can select this if
you wish to run the booth monitor in mono rather
than stereo. Note that the MONO switch does not
affect the headphones monitor.
9 BOOTH MONITOR level control. Adjusts the
level of the signal to the stereo booth monitor
output. This does not affect the level in the
10 MUTE switch. Press to mute the booth
monitor output. The switch cap lights when the
monitor is muted. The headphones and main output
are not affected. This is useful when the DJ
chooses to work with headphones only, check the
sound level from the dance floor, or quieten the
monitor to talk to staff or take a request.
7 HEADPHONES OUTPUT. This output is
positioned on the front panel so that the DJ can plug
in his favourite headphones without needing access
to the rear connector panel. Headphones are
available in many different styles, impedances and
volume ratings. To get the best from your system
we recommend that you use high quality closed-ear
headphones in the range 30 to 100 ohms. 8 Ohm
headphones are not recommended. Avoid using
mini-jack to ¼” jack adapters as these may quickly
prove unreliable.

Asymmetric EQ An equaliser with a different
amount of cut and boost of the frequency bands.
This is used to restrict the available boost so
preventing system overload while providing
extended cut to allow dramatic performance effects
by ‘killing’ selected frequencies.
Attenuate Reduce the signal level.
Aux Auxiliary. An independent mix derived from
the channels for various functions. This can be set
pre (before) or post (after) the channel fader. Prefade sends are often used for foldback monitors or
DJ sampler effects feeds. Post-fade sends are
often used for reverb effects, zone and special
recording feeds.
Balanced, Unbalanced Refers to the type of input
or output signal connection. An unbalanced
connection has two signal carrying conductors, one
of which is the cable shield. A balanced connection
has three conductors, two for signal and a shield
which is connected to earth. Because the signal
conductors are at the same impedance and of
opposite polarity they are better able to cancel and
therefore reject interference and noise pickup. It is
standard practice to use balanced connections for
long cable runs, for example to amplifiers, or cables
carrying sensitive or low level signals, for example
Bandpass A filter with a bell-shaped response for
attenuation of frequencies either side of the centre
Beat Mixing Using the variable pitch controls on
turntables/CD players to synchronise the rhythm
track of two separate songs, so that the beat
remains constant when smoothly cross-fading from
one to the other.
Bi-amping Providing separate amplifiers to drive
the high and low frequency units in a loudspeaker.
This requires a crossover processor that splits the
frequency band into low and high. Bi-amping
usually produces a cleaner and more controllable
sound in larger systems.
BPM Beats Per Minute. The measurement of the
rhythmic beat of the music.
Booth The area, often enclosed, where the DJ
operates. Usually provided with local booth monitor
Cardiod The response of a microphone which is
more sensitive in front than behind. This is
XONE:62 User Guide
generally used for vocal miking to reduce acoustic
Cut Mixing Moving the cross-fade control sharply
from one side to the other, to either pick out a
sound, a hi-hat, kick drum etc, or to drop straight
into another record. Also known as chopping.
Cartridge The pickup in a turntable. Uses a
needle to pick up vibrations from the record (vinyl)
and convert this to electrical signals that feed the
console. The cartridge is usually fitted to a
removable headshell that plugs into the turntable
Clipping The harsh distorted sound that results
when the signal hits the maximum level possible.
This is set by the power rail voltage. Above this
there is simply no more voltage available so the
signal is ‘clipped’.
Compact Disc (CD) Well established stereo
player using digitally mastered pre-recorded flat
discs. Becoming popular with DJs as a replacement
or alternative to vinyl mixing. Recordable CDs are
now available.
Crossfader A short horizontally mounted fader for
smoothly fading one music track in while fading the
other out. Often used by the DJ for cutting and
layering sounds while mixing.
Cue A monitor system provided for the DJ or
console operator to check individual channel signals
using headphones while lining up tracks ready to
introduce into the mix. This does not affect the main
console outputs.
DAT Digital Audio Tape. A type of digital 2 track
recorder that uses a small tape cartridge to produce
high quality recordings in a compact format.
dB Decibel. The unit of measurement for audio
signal level. This is logarithmic to follow the
response of the human ear. ‘dB’ is a relative
measurement to compare one level with another, for
example gain from input to output. ‘dBu’ is an
absolute measurement referenced to a voltage
standard where 0dBu = 0.775V rms. The console
main outputs operate at the professional ‘high’
standard of +4dBu (1.23V) = ‘0’ reading on the
meters. '’dBV’ is a similar measurement but refers
to a 1V standard. It is common for consumer
equipment to operate a the ‘low’ standard of –
10dBV (316mV). ‘dBA’ refers to sound pressure
level and is measured using the ‘A’ scale that
‘hears’ in the same way as the human ear.
DJ Disc Jockey. The console operator sequencing
and playing the music tracks. Some simply play the
tracks, others talk over with introductions and
announcements, and others provide an entertaining
performance by mixing and shaping sounds to
create a completely different musical experience.
Hum Apart from not knowing the words… this is
the audible noise that usually results from mains
interference pickup, earth loops, bad
interconnections and induced power supply and
lighting fields. It is usually at mains frequency
(50/60Hz) or a related harmonic.
Drum Machine An electronic drum simulator as
used by keyboard players and in electronic music.
This now provides another DJ tool to create an
alternative beat to mix in with the music.
Impedance (Z) A technical term for the resistance
of a signal conductor to ground. Low impedance
usually refers to microphones of 200 ohms or less,
and line signals typically less than 100 ohms. Low
Z sources are less prone to interference pickup.
Inputs are usually high impedance so that one
source can connect to more than one channel
without signal loss. Note that the operating
impedance of a connection is set by the impedance
of the source, not that of the unconnected input.
Dynamic Range The difference expressed in dB
between the highest and lowest signal levels
possible. This is limited by the clipping level and
residual noise floor respectively.
Earth Also known as ‘ground’. The term for the
electronic signal reference. This connects to the
mains supply earth point and all cable shields and
conductive equipment cases. It provides the return
for the signal voltage within the equipment. It also
ensures operator safety by removing the possibility
of electric shock should the mains voltage touch any
metal part.
Earth Loop The result when the equipment sees
more than one path to the system earth. Current
flows because a resistive loop susceptible to radio
and mains interference is formed. This can result in
audible hum or buzz in the system.
Equaliser (EQ) This provides cut or boost of
selected frequencies (equalisation) for tonal shaping
of the sound. This is similar to the bass and treble
controls of domestic hifi amplifiers. However, XONE
provides 4 independently controllable frequency
bands for corrective or effective sound shaping.
Feedback Also known as ‘howlround’ or ‘ringing’
this is the rapidly increasing tone produced when a
microphone picks up its own signal from the
speakers. It is usually a shrill and annoying squeal
that should be quickly dealt with by reducing mic
gain or equalising the system to notch out the
offending frequencies.
Gain This is the boost or attenuation applied to the
source signal in the channel preamp stage to match
it to the console operating level. For example, a
large amount of gain is need to match low
microphone signals. It is set using the console
meters. Gain is not used for level (volume) control.
Headroom The amount of level available
expressed in dB to handle peaks above the normal
0dB operating level.
Hz Hertz. The measurement of frequency. The
audio spectrum ranges from a low (bass) frequency
of 20Hz to a high (treble) 20kHz. Not many sound
systems reproduce the full range. Average hearing
does not extend much beyond 15kHz or so.
Response is further impaired if the ear is subjected
to continual high sound pressure levels.
Highpass A filter that attenuates frequencies
below the cut-off frequency.
Impedance balanced Refers to the type of output
signal connection. Has three conductors, two for
signal and a shield which is connected to earth.
Provides interference rejection similar to a fully
balanced connection because the two signal
conductors are matched at the same impedance.
However, the drive capability is less because the
signal is carried by only one conductor.
Limiter A signal processor that limits the maximum
level possible by preventing the signal going over a
predetermined threshold level. This is very useful in
club installations where it is inserted between the
console and house system amplifiers to prevent the
DJ exceeding the maximum allowable volume.
Lowpass A filter that attenuates frequencies
above the cut-off frequency.
MC Master of Ceremonies. The presenter who
introduces the performances and maintains the
running order.
MiniDisc A type of low cost digital 2-track recorder
that uses a disc similar to but smaller than that used
by computers. It records up to 74 minutes of stereo
material and is regarded as the modern
replacement for the audio cassette recorder. It has
the added facility to label and edit tracks.
Mono The left and right stereo signals summed
together as one.
Mute To turn off the signal.
Noise Generic term for an unwanted signal. This
may be residual electronic hiss, hum, buzz, clicks
and pops, or simply loud undesirable music.
Noise Floor This is the term for the residual
electronic noise produced by all powered audio
equipment. It usually sounds like a constant hiss,
although some equipment may suffer from residual
hum as well.
Omni-directional The response of a microphone
which picks up sounds equally all round. Not suited
to live vocal applications as they are more prone to
feed back.
XONE:62 User Guide
Pan Panoramic. A control that adjusts the balance
of the signal in the left and right speakers.
Peak Meter A type of signal meter that has a very
fast attack and slower release. This picks up the
fast signal transients and holds them long enough
for the operator to see the activity on the display.
These meters typically use led (light emitting diode)
Phantom Power The DC voltage required by
certain microphones to power the capsule. These
are usually sensitive studio grade mics not suited to
DJ mixing. The power is provided by the console
using the two signal conductors in the balanced
connection. There is no provision on XONE for this
type of microphone.
Phono Abbreviation for phonograph as in
‘turntable’. Usually means RIAA equipped input
when marked on console inputs. Can also refer to
the RCA ‘phono’ type pin jack connector found on
turntables, CDs and much domestic equipment.
Polarity Sometimes referred to as ‘phase’ this is
the + / - sense of a balanced signal or loudspeaker
connection. Reversed polarity should be avoided
and checked for as it can cause uncomfortable
phasing effects between speakers.
Resonance Applied to the filters this is the effect
of accentuating frequencies around the cut-off point
to produce subtle or dramatic phasing effects.
RIAA Record Industry of America Association,
responsible for the long established equalisation
standard that is applied to the signal produced by a
turntable cartridge. Due to the physics of vinyl
reproduction the needle produces a reasonable high
frequency signal but much less low frequency. An
RIAA pre-amplifier compensates for this by
inversely attenuating the high and boosting the low
Reverberation The way in which sound reflects
and bounces around the room after the source is
removed. This depends on the size and shape of
the room as well as the materials such as carpets,
curtains and clothing that absorb certain
Reverb Effect This is a signal processor that
connects to the console to artificially simulate the
reverb effect. Parameters such as decay time,
diffusion and amount of reverb can be controlled.
Typically selected sounds are sent to the processor
by turning up the channel post-fade aux sends. The
processed (wet) signal is returned to the mix
through a channel where it adds to the direct (dry)
signal routed from the channel fader.
RPM Revolutions Per Minute. The measurement
of turntable speed.
Sampler Another performance effect popular with
DJs. The channel signal is sent to a digital
XONE:62 User Guide
processor that samples (stores) a short duration of
sound. The output is returned through a channel
and replayed by pressing a trigger. Many samplers
provide creative effects such as repeat and reverse.
Scratch Mixing The art of rhythmically rocking a
record back and forward on a turntable, to repeat a
certain sound, a vocal or tone, at the same time
operating the cross-fader to create a syncopated
“wah wah” chirp added over a bass heavy back
Signal-to-Noise Ratio (SN) This is the difference
expressed in dB between the normal 0dB operating
level and the residual noise floor. It represents how
far above the equipment hiss level the signal
operates. More is better.
Slipmat A fabric turntable mat positioned under
the record so that the DJ can hold it stationary ready
to let go for a fast start at the point cued.
Sound-to-Light A processor that converts an
audio signal into a control voltage that triggers
lighting effects. This produces the popular disco
effects with lights flashing in time to the beat.
Split Cue A facility to listen to the cue signal in one
ear while keeping the program in the other. Used
for matching the beat while cueing a new track.
Sub Bass A loudspeaker designed to reproduce
only very low frequency sound, typically from
around 50 to 120Hz. A crossover is used to route
only the low frequencies to the sub.
TRS Jack Refers to the 3-pole (stereo) ¼” jack
plug with Tip, Ring and Sleeve connections.
Turntable Otherwise known as a ‘record deck’ this
plays vinyl discs, still the most popular source for DJ
mixing. It is common for the cartridge to plug
directly into the mixing console ‘phono’ input which
provides the RIAA equalisation required. The
turntable usually has variable speed control so that
the DJ can synchronise the beat between tracks.
VCA Voltage Controlled Amplifier. An audio gain
element whose level is controlled by a remote DC
voltage rather than through a fader or rotary control.
VCA Crossfader Functions as an audio
crossfader but with the audio level controlled by a
DC voltage produced by the fader. This voltage can
be electronically filtered and is therefore able to
remove the clicks, scratches and drop-outs
associated with worn audio faders.
VCF Voltage Controlled Filter. An audio filter
whose cut-off frequency is controlled by a remote
DC voltage rather than a rotary or switched control.
This provides greater range and capability.
XLR The professional standard 3 pin round
connector used for microphone and other balanced
connections. Equipment female sockets are for
inputs, male for outputs.
Tips and Troubleshooting
For your safety do not remove the EARTH
(ground) connection in the power lead of the
console or connected equipment.
Have your MAINS SYSTEM checked by a
qualified electrician. If the earthing is solid to start
with you are less likely to experience problems.
Use high grade AUDIO CABLES and check
them for reliable connection. It is well known that
many audio system problems are due to faulty
cables and connectors.
In a club or similar installation strict SOUND
LEVEL and noise regulations may apply. Check
that your system levels are correctly set up to
To avoid damage to your hearing start with
the HEADPHONES level control at minimum and
turn up only as much as is needed to maintain
comfortable listening level. Do not drive
headphones at high listening levels for long periods
of time.
Always switch connected AMPLIFIERS on
last and off first to avoid thumps when the console
and connected equipment is turned on or off.
Reduce gain if the red meter PEAK led
flashes. These warn you that you are near clipping
which may result in system overload and distortion.
The XONE:62 provides plenty of drive and
headroom when operated around the 0 to +6 meter
points. Check that the amplifier / speaker system is
correctly matched and set up for correct levels.
Increasing VCF RESONANCE boosts a
narrow band of selected frequencies. Make sure
you reduce the channel gain if the red peak meters
start to flash. It is best to start experimenting with
this control set to minimum.
If you suspect a console fault. The console
is the heart of the audio system and is often
suspected faulty when a problem occurs. Usually
the fault is found to be with other equipment in the
system, typically the interconnecting leads, input
sources, or level matching between equipment.
Check for source problems by unplugging each
channel in turn listening for a change in symptom.
To check the console, isolate it by unplugging all
sources and outputs leaving just headphones and a
reference source such as a CD player connected.
I have plugged in a microphone but it does
not work. The XONE:62 is designed to operate
with non-phantom powered dynamic microphones
such as the popular vocal types. Do not use
microphones which require phantom power.
The stereo channel sounds very distorted
with high level and excessive bass. Only plug
turntables needing RIAA equalisation into CH 3-6
PHONO inputs. Other equipment should be
plugged into the LINE inputs.
? There is a hum on the turntable channels.
Check that the turntable earth strap has been
correctly connected to the console chassis earth
post. Also check that the turntable headshell and
cartridge are correctly aligned and plugged in.
? Only one side of the stereo mix is working.
Check that the XFADE PAN control is not set fully to
either L or R. Also check for bad connections, in
particular turntable headshell and cartridge pins.
There is feedback. Check that the microphone
is not placed next to the headphones. The mic may
pick up its own signal from the headphones and
feed back. In loud listening conditions feedback can
sometimes be caused by mechanical vibration
through the turntables into the cartridge, or even the
needle resting on a cued turntable starting to
resonate in the groove of the record.
When the VCF is switched on there is very
little sound. Operate the VCF frequency control to
restore the frequency content of the sound.
There is no monitor output. Check that a
channel CUE switch is not already selected. This is
indicated by the red CUE led under the monitor
meters. Also check that AUX is not selected.
There is no stereo channel signal. Check
that the input selector switch is correctly set.
? The crossfader is not working. Make sure
the channel XFADE ON switch is pressed and X or
Y correctly selected.
The crossfader works backwards. Check that
it has been re-fitted the right way round if previously
I have connected a stereo source to a single
input using a Y-adapter but it sounds bad. Do
not connect more than one output to the input.
These adapters are designed to feed one output to
two inputs, not the other way round.
