Important Safety Instructions

WARNINGS - Read the following before proceeding :

CAUTION

ATTENTION: RISQUE DE CHOC ELECTRIQUE – NE PAS OUVRIR

Read instructions: Retain these safety and operating instructions for future reference.

Adhere to all warnings printed here and on the console.

Do not remove covers: Operate the console with its covers correctly fitted. Disconnect mains

power by unplugging the power cord if the covers need to be removed
for setting internal options. This work should be carried out by
competent technical personnel only.

Power sources: Connect the console to a mains power only of the type described in

the User Guide and marked on the rear panel. Use the power cord
with sealed mains plug appropriate for your local mains supply as
provided with the console. If the provided plug does not fit into your
outlet consult your service agent for assistance.

Power cord routing: Route the power cord so that it is not likely to be walked on, stretched

or pinched by items placed upon or against it.

Grounding: Do not defeat the grounding and polarisation means of the power cord

plug. Do not remove or tamper with the ground connection in the
power cord.

WARNING: This equipment must be earthed.

Water and moisture: To reduce the risk of fire or electric shock do not expose the console

to rain or moisture or use it in damp or wet conditions. Do not place
containers of liquids on it which might spill into any openings.

Ventilation: Do not obstruct the ventilation slots or position the console where the

air flow required for ventilation is impeded. If the console is to be
operated in a rack unit or flightcase ensure that it is constructed to
allow adequate ventilation.

Heat and vibration: Do not locate the console in a place subject to excessive heat or

direct sunlight as this could be a fire hazard. Locate the console away
from any equipment which produces heat or causes excessive
vibration.

Servicing: Switch off the equipment and unplug the power cord immediately if it

is exposed to moisture, spilled liquid, objects fallen into the openings,
the power cord or plug become damaged, during lightening storms, or
if smoke, odour or noise is noticed.

Installation: Install the console in accordance with the instructions printed in the

User Guide. Do not connect the output of power amplifiers directly to
the console. Use audio connectors and plugs only for their intended
purpose.

XONE:62 Service Manual 3

Important Mains plug wiring instructions.

The console is supplied with a moulded mains plug fitted to the AC
mains power lead. Follow the instructions below if the mains plug has
to be replaced.

The wires in the mains lead are coloured in accordance with the
following code:

TERMINAL

L

N

E

The wire which is coloured Green and Yellow must be connected to
the terminal in the plug which is marked with the letter E or with the
Earth symbol. This appliance must be earthed.

The wire which is coloured Blue must be connected to the terminal in
the plug which is marked with the letter N.

The wire which is coloured Brown must be connected to the terminal
in the plug which is marked with the letter L.

Ensure that these colour codes are followed carefully in the event of
the plug being changed.

Precautions

WIRE COLOUR

European USA/Canada

LIVE BROWN BLACK

NEUTRAL BLUE WHITE

EARTH GND GREEN & YELLOW GREEN

Damage : To prevent damage to the controls and cosmetics avoid placing heavy

objects on the control surface, scratching the surface with sharp
objects, or rough handling and vibration.

Environment : Protect from excessive dirt, dust, heat and vibration when operating,

servicing and storing. Avoid tobacco ash, smoke, drinks spillage, and
exposure to rain and moisture. If the console becomes wet, switch off
and remove mains power immediately. Allow to dry out thoroughly
before using again.

Cleaning : Avoid the use of chemicals, abrasives or solvents. The control panel is

best cleaned with a soft brush and dry lint-free cloth. The faders,
switches and potentiometers are lubricated for life. The use of
electrical lubricants on these parts is not recommended.

Transporting : The console may be transported as a free-standing unit or mounted in

a rack or flightcase. Ensure that the connector pod is secured in place
with the locking screws fitted to prevent movement. Protect the
controls from damage during transit. The faders are best positioned at
the top of their travel if the console is transported without a suitable
flightcase, rack or carton. Use adequate packing if you need to ship
the unit.

XONE:62 Service Manual 5

Welcome to the XONE:62

From the User Guide:

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.

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.

VERSION 1 and VERSION 2 Model Differences

There are minor changes between the original XONE:62 and the revised model
which replaced it in October 2000. This service manual covers both models.
Spares and support are available for both models. When servicing or ordering
spare parts for a XONE:62 first check which model it is.

The original model is referred to as VERSION 1. Its order code is XONE:62/.
Its key identifiers are:

Serial number sequence 020000

Stainless steel panel. Linear MIX master fader.

The newer model is referred to as VERSION 2. Its order code is XONE2:62/.
Its key identifiers are:

Serial number sequence 030000

Painted silver panel. Rotary MIX master control.

The following is a summary of the differences introduced on VERSION 2:

Styling The original stainless steel finish is replaced with a new textured silver
paint. Several knob and pushbutton types have been changed to further co­ordinate the styling. There are minor changes to the graphics.

Master Level Controls The original MIX master linear fader has been
replaced with a rotary master control.

Crossfader The new high grade Penny & Giles fader is fitted instead of the
original Alps version. These are not interchangeable with VERSION 1.

Power Supply The power supply assembly was changed to improve
production efficiency.

The circuit information is mostly identical between the two models. Differences
are noted on the diagrams.
