CAU TION
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. Follow the operating instructions printed in this User Guide.
Do not remove cover:
Operate the console with its covers correctly fitted.
Power sources:
Connect the console to a mains power unit only of the type described in this 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. Refer servicing to qualified technical personnel only.
Installation:
Install the console in accordance with the instructions printed in this User Guide. Do not connect the
output of power amplifiers directly to the console. Use audio connectors and plugs only for their intended purpose.


Allen & Heath
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.
Protect from excessive dirt, dust, heat and vibration when operating
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.
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. The fader and potentiometer knobs may be removed for cleaning with a warm soapy solution. Rinse and allow to dry fully
before refitting them.
The console may be transported as a free-standing unit or mounted in
a rack or flightcase. Protect the controls from damage during transit. Use
adequate packing if you need to ship the unit.
To avoid damage to your hearing do not operate any sound system at excessively high volume. This applies particularly to close-to-ear monitoring such as
headphones and in-ear systems. Continued exposure to high volume sound
can cause frequency selective or wide range hearing loss.

INTRODUCTION TO THE XB-14
Background overview:
The Allen & Heath XB-14 mixer has been carefully and lovingly designed in the beautiful county of Cornwall in the UK and is manufactured alongside a wide range of professional audio mixing consoles. Many of the components used in the XB-14 are exactly the same as in
the larger Allen & Heath products and the construction methods are also very similar utilising individual vertically mounted channel circuit
boards with each rotary control fixed with a metal nut to the front panel. This provides a very robust product that will resist damage and
give years of reliable use. It also makes servicing much easier should it be required, with the ability to remove one particular channel from
the mixer at a time, or easily change a fader.
The audio circuitry is based on years of continual development and refinement , the performance of all the elements within the mixer
scrutinised and perfected to ensure the very best sound quality possible.
Multi-application:
The XB-14 is great for a range of applications from small radio or internet broadcast studios, or for larger studios with multiple rooms,
for hospital radio, university radio and community radio broadcast applications. The XB-14 has a wealth of features specifically designed
for broadcasters, things like telephone communication modules for telephone callers, mic fader start sensing for external connection and
internal automatic muting of the speaker outputs, stereo channel start/cue outputs for CD deck transport control, separate headphones
mix & outputs for guests, an audition bus…. The list goes on!
Mic/Line Pre-amps:
The XB-14 pre-amps use a two stage design, with carefully controlled amounts of gain in each stage. When amplifying the signal from the
XLR input, the gain range is huge (69dB of range to be exact) and is very evenly distributed around the gain control, meaning better control of signal level. Most of the gain comes from the first stage, so unwanted noise is kept to a minimum. There is no “pad” switch, or pad
circuit — line level signals are simply plugged into the second stage of the pre-amp by using the line input jack socket. This has the great
advantage of lower noise when using the line input. (It is common to attenuate line level signals, then amplify them back up again which can
give more noise or hiss).
EQ:
The XB-14 is equipped with a 3-band equaliser circuit on each mono input which can be used to cut sibilance or mic popping or to
change the tone of a presenters voice. The telco channels are fitted with a total cut high pass and low pass filter which can be used to
eliminate the top or bottom end of the channel frequency response. This can be very useful when a caller is connected via a low quality
telephone line. Stereo channels have high and low frequency tone controls for use with music.
AUX bus:
XB-14 has a single Auxiliary bus that can be used for external processing, effects, recording or auditioning.
MIX B:
A separate stereo mix bus is provided for recording an independent mix to the main program mix, or creating a clean feed source with
selected channels.
Audition bus:
The XB-14 has a dedicated stereo audition bus that can be used for auditioning or off air recording. Pressing the button marked AUD on
the channels required, transfers the mix from the program feed over to the audition bus.
Channel signal/peak indicators:
Each channel on the XB-14 has an indicator to show if there is signal present. This is pre fader / ON switch so the operator can be aware
of channels that are active. The peak LED also gives a warning if a channel is in danger of exceeding its peak level.
Remote Control:
The mono mic/line channels have fader start logic switching enabling them to control external equipment or automatically mute the speaker outputs to prevent acoustic feedback in localised or self-operated applications. The stereo channels have start & cue logic outputs available to hook up to external equipment like CD players. There are also options to mute the mono inputs remotely using an external
“cough” switch or similar.

INTRODUCTION TO THE XB-14
USB:
Getting audio to and from a computer easily is now a common requirement for sound and music production and broadcast applications.
The way we have implemented this on XB-14 is super-flexible and super-easy! No longer do you need to fiddle around the back of your
computer to get to the soundcard inputs, only to find that the levels are all wrong and noisy. Just plug in a USB lead to your XB-14, select
the USB routing on the mixer and the device on your computer and that’s it! Quality audio to and from your PC or MAC.
Guest headphones:
The XB-14 has 3 headphone outputs. There is a headphones socket for the presenter/engineer with a routing matrix. There are two guest
headphone outputs with a separate routing matrix. There is also a talk button for off air conversation with guests via the user selected
comms mic channel.
Output matrix:
Both the operator and guest headphone outputs (and the control room speakers) have an output matrix with priority switched feeds. This
means the operator could be monitoring one bus while a guest is listening to the program mix. There are many possible combinations.
Electronically balanced outputs:
The main program outputs are on XLR connectors with an electronically balanced output circuit.
Self operation or Producer operated:
Whether you need a mixer for a self operated broadcast situation, or whether you have a separate studio and engineer, the XB-14 has
the features to fit. Separate monitor mixes can be created for operator and guests or presenter so the engineer can check levels and cue
sources while the presenter or guest can listen to a different source. The engineer/producer can communicate to the guest or presenter
using the Talk feature, as well as off-air communication to telephone callers.
There is also the facility for remote control of channel mutes from the studio using the remote interface connectors, ideal for studio situated mute switches.
