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. 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.

XB-14 User Guide
INTRODUCTION TO THE XB-14
The following is a technical overview of XB-14, if you want to, please skip to the next section.
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 and a 2-band EQ on the Telco & stereo channels. The frequency
and response of each has been carefully chosen to give the maximum performance when using the EQ on a variety of sources.
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.
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.
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.
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.

Nominal level is 0dBu. The insert point is after the 100Hz filter and
before the EQ.
This adjusts the gain of the input amplifier to match the signal level
of the input. The gain is varied from –6dB (attenuation) to +63dB

HF EQ
The HF (High Frequency) equaliser affects the frequency response
of the higher audible frequencies. The corner frequency of 12kHz is
around 3dB from the maximum cut or boost of the circuit. It has
plenty of gain and actually gives slightly more that the +/-15dB legend suggests.

MF EQ
The MF (Mid Frequency) equaliser affects the middle of the audible
frequency range. The frequency graduations on the sweep control
are the centre frequencies of the EQ. The range has been carefully
chosen to cover “boomy” frequencies around 120Hz to 250Hz
which may need cutting back, or a lift at 2 to 3kHz may be required
for microphone intelligibility.

Press this in to switch 48v Phantom Power to the 4 Mic input xlr
connectors, if any of the microphones attached require power.
Dynamic microphones won’t mind being connected to a phantom
powered input, but care is needed to ensure that 48v is not switched
on if an xlr is used to input a signal from an electronic circuit (ie. Another mixer or keyboard).
When switching 48v on or off, or plugging in connectors to
channels with 48v present, it is important (and normal procedure) to mute the channels. This will avoid loud clicks and
bangs potentially getting through to the amps & speakers
with the possible effect of damaging the speakers, or the audience’s hearing!
These 4 switches select the signal source for the control room speakers, headphones monitor and the meters. They work on a priority
basis. If they are all up then the post-fade main PGM signals will feed
the monitor circuit, if any of the switches are pressed then the PGM
signal will be replaced. If more than one switch is pressed the switch
nearest the meters will take priority.
The PFL signal will override the selection to the meters and CRM if
activated.
Similar to the CRM + PHONES selection switches, these select the
source for the guest headphones output. The choices are the same as
for the CRM outputs, but a different source can be selected for the
guests to that selected for the operator.
The PFL signal will not be fed to the guest phones outputs unless the
PFL ENABLE TO GUEST switch is pressed. This is an under-panel
switch so it cannot be operated accidentally.

Start/Cue logic
The Start/Cue logic from the Stereo channel ON switches is designed to interface to a common standard employed
by Denon and Pioneer equipment. The logic signals are usually wired to a 2 pole 3.5mm jack plug where a low pulse
on the tip starts the deck and a low pulse on the sleeve stops or cues the deck. There needs to be some form of
ground connection between the equipment for this to work—normally effected by the audio connector leads.
Notice that there are Start/Cue outputs for 7 machines even though there are only 4 Stereo channel ON switches.
That’s because there are dual inputs on 3 of the stereo channels making a total of 7 sources and the XB-14 only sends
a Start/Cue signal to the deck selected as a source to the channel whose switch is pressed. It’s clever like that!

Configuration Switches
The tiny slide switches accessible on the rear panel are for configuring the XB-14’s channel ON switches. In the up position,
the channel ON switch will act as a normal ON/OFF switch affecting the channel signal accordingly. If the slide switch is moved
down to the “ON” position, then the corresponding channel’s ON switch will be disabled (made so that it is jammed ON).
The green LEDs in the switch will then permanently illuminate. UNLESS….
Unless you are using the Stereo channel ON switches for transport Start/Cue and would like the channel mute circuit disabled
but the switch illumination still to follow the switch position. In this case use the last switch in the row to disable the mute
circuit on all 4 stereo channels, but make the illumination follow the switch position.
If you want, you can disable the Stereo channel mute circuit on an individual channel basis using the Stereo Inputs 1,2,3 & 4
slide switches individually. This will make the channel permanently on and the switch illumination also permanently on.
This may seem like a fussy complication, but could be useful if you want to revert to basic operation, where only the faders
control the signal going out on air, disabling the ON switches so the operator cannot turn off the channel accidentally, but still
want the switch illumination on certain stereo channels to follow the Start/Cue on the CD player or deck.
ALSO SEE P21 FOR A DIAGRAM TO EXPLAIN THESE SETTINGS.

REMOTE A Connector wiring
The REMOTE A connector is used for the “Fader Up” logic signals from the Mono and Telco channel faders. It is also
used for remote muting of channels and control room speakers. An example of how these remote signals can be used
is below:

USB Audio Interface
The XB-14 is equipped with a stereo bi-directional USB 1.1 compliant audio CODEC. It is fully compliant with USB 2
ports and uses standard Windows and MAC Core Audio Drivers. In other words, plug it in and your computer will find it
and be able to transfer audio to and from the XB-14 USB device.
You will need some form of audio software running on your computer to be able to record and play back what you record, but on a basic level, you can use your computers media player to play straight to the XB-14 device.
Just a couple of points to look out for:
1.
When you plug in your XB-14 USB interface to your Windows computer, check the device volume in:
Control Panel\Sounds & Audio Devices\Volume
If the volume is not fully up
like this…...
Then drag it fully up
like this…...
Then click Apply
2.
By default Windows will use its WDM driver for the data stream from the USB audio device. There are other drivers available from third party companies like ASIO4ALL (www.asio4all.com) who supply ASIO drivers for WDM audio
which is free to end users.
