Allen & Heath 8 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.

Aux
This control sends a signal to an auxiliary bus. The signal is sourced pre-fade
or post-fade depending on the PRE switch position. The pre-fade source
selection will be affected by the channel ON/OFF switch if active. The send
control varies the signal level to the bus from off (fully attenuated) to +6dB,
with unity gain at the arrow.
MIX B
The MIX B switch routes the channel signal to a stereo bus which is independent of the main PGM (program) bus. The signal is post-fade and follows
the PAN control. The MIX B bus can be used for creating mixes for recording or clean-feed sources for external equipment.
PAN
The pan control adjusts how the signal from the mono input channel is
shared between the left and right sides of the PGM bus and the MIX B bus.
Set to the mid position, equal amounts of signal are fed to left and right,
with pan set to L, none is sent to the Right bus.
ON Switch
This mechanically latching switch operates the channel mute circuitry, turning the signal to the PGM, MIX B and Aux buses on or off.
The switch is illuminated green when pressed.
There is an option to disable the switch (make permanently ON) using the
option switches on the rear-panel. If this is activated, then the switch will be
illuminated green regardless of whether it is pressed or not.
There is also a remote mute option wired to a D type connector on the
rear panel. When this is wired and operated the REM MUTE red LED illuminates and the mute circuit is activated regardless of whether the ON switch
is pressed.

level is detected (pre-fader signal) within 5dB of clipping.
PFL Switch
The PFL (Pre-Fade Listen) switch sends the channel signal to the PFL bus
and subsequently to the headphones/CRM speakers and the main L R meters. Used for checking the audio signal before raising the fader or unmuting the channel or raising the fader.
Fader
The 100mm fader controls the level of the channel signal to the left & right
PGM bus, MIX B bus and post fade Aux.
The Mono channel faders have Fader Start switching logic available to either
interface to external equipment or activate the muting circuit for the control room speaker outputs.

TALK
6
The TALK switch enables the presenter or operator to communicate with
the telephone caller with the presenters channel fader down so the presenters voice does not go to the program mix.
The source for the TALK signal is one of the mono channels, pre-selected
by links set within the XB-14, the factory default is mono channel 1. The
signal source is pre-fade and pre-mute on the selected mono channel.
CLF SCE
7
The Clean-Feed Source switch selects the signal source for the TELCO output. In the un-pressed position the signal will be the entire program (PGM)
mix (pre main PGM fader) but without the signal from the input on that
TELCO channel, so the caller does not hear any distracting echo of their
voice.
If the switch is pressed, the TELCO output signal is sourced from the AUX
bus, but minus the AUX signal sent from that TELCO channel.
This is a really useful feature that can enable the operator to send a mix of
signals from different channels to the telephone caller using the AUX bus,
the sources may be on or off air because the sources for the AUX bus can
be pre or post fader.
In addition, the AUX bus can be used for off-air audition or recording of an
interview with a telephone caller (or callers), using pre-fade signals to the
AUX bus for later playback or editing for the broadcast. By pressing the CLF
SCE switch the caller will hear the audition mix, or the off-air record mix
without their own voice.

48v Phantom Power switch
8
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!

CRM + PHONES Source Selector switches
11
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.
GUEST PHONES Source Selector switches

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.

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.
