WZ314:4:2 User Guide
Introducing the MixWizard WZ314:4:2
The Allen & Heath MixWizard series of consoles includes several models. This user guide
3
3
3
describes the WZ 14:4:2 4 group model. The 2 bus WZ 12:2 and WZ 16:2, and the stereo
input WZ20S consoles are described in separate publications. For further information on the
MixWizard series please refer to the Allen & Heath web site.
The MixWizard is a compact console designed for
professional sound mixing. It is built to the same
high standards as our top of the range consoles, with
individual circuit cards, potentiometers nutted to the
panel for absolute strength, steel chassis, and no
compromise circuit design ensuring the finest sonic
performance.
The console can be operated free standing or in a
19” rack or flightcase. It is supplied with protective
side trims fitted. These can be removed for rack
mounting. The rear connector pod can be easily
rotated for rear facing or underside connectors when
rack mounted.
With its 4 band semi-parametric EQ, 4 groups, 6
auxes and stereo main output the WZ314:4:2 is
equally at home mixing live shows, recordings and
corporate events. Tamperproof recessed switches
configure the console for optimum FOH or stage
monitor operation.
This ‘dual functionality’,
pioneered by Allen & Heath, gives the console its
unique ability to properly function as Front-of-House
or stage monitor, or handle both at the same time,
ideal as a hard working work horse for hire stock,
touring and installed sound.
The WZ314:4:2 has 10 mono mic/line inputs, 2 fully
featured dual input stereo channels and a 2-track
replay input, a total of 20 inputs to the mix. Of
special note is the addition of a 2 x 6 way matrix
providing a useful multi-purpose output for those
special demands such as recording and broadcast
feeds, delay fills, zone feeds and so on. A host of
top end features are provided including oscillator and
pink noise generator, individual talkback to all
outputs, comprehensive engineer’s metering and
monitoring, a lamp socket, and a dual redundant
backup power supply input.
The base of the console can be removed to access
internal pluggable option jumpers. These configure
user preference for the aux sends, direct outputs and
talkback mic phantom power. The aux and matrix
outputs are impedance balanced but may be
electronically balanced if required by fitting an
optional part. A kit is also available to fit the optional
Sys-Link II input/output card which allows the
console to be linked to other Allen & Heath consoles.
Other accessories available include the Allen &
Heath MPS12 backup power supply and LEDlamp
gooseneck lamp with built-in dimmer.

WARNING: THIS APPARATUS MUST BE EARTHED
Serial No.
Read and understand the Important Safety Instructions printed at the start of this guide,
and the warnings printed on the rear of the console. Check that your local mains supply is
within the 100-240V operating voltage range allowed. Check that the correct mains lead
with moulded plug has been supplied with your console. Make sure that the IEC mains plug
is pressed fully into the panel socket before switching on.
Grounding
The connection to ground in an audio system is important for two reasons:
1.
SAFETY - To protect the operator from high voltage electric shock, and
2. AUDIO PERFORMANCE - To minimise the effect of ground (earth) loops which result in
audible hum and buzz, and to shield the audio signals from interference.
For safety it is important that all equipment grounds are connected to mains ground so that
exposed metal parts are prevented from carrying high voltage which can injure or even kill
the operator. Do not disconnect the ground connection in the mains lead. It is
recommended that the system engineer check the continuity of the safety ground from all
points in the system including microphone bodies, turntable chassis, equipment cases, rack
metalwork and so on.
Switching the console on and off
It is good practice to turn power amplifiers off before switching the console and any other
connected equipment on or off. This prevents any unexpected clicks or thumps when the
equipment is powered up.
Turn amplifiers and powered speakers on last and off first.
To turn the console on, press the ON/OFF switch next to the IEC mains input socket. To
turn the console off, press this switch again.
Connecting a backup supply
A socket is included for plugging in an optional backup power supply. This provides the
reassurance of power supply dual redundancy, a feature usually found only in expensive top
end consoles. The console uses diode combining technology so that both supplies can be
powered at the same time. One will automatically take over should the other stop working.
The recommended backup supply for the MixWizard is the Allen & Heath MPS12 power unit.
Refer to the user guide which comes with this supply.
Only plug the recommended Allen & Heath power unit into this socket. Do not
attempt to modify any other power unit to work with the console. Do not attempt to modify or
extend the DC power cable that comes with the supply.
The console can work with just the internal supply powered by mains, or just the backup
supply, or with both powered at the same time. To ensure uninterrupted performance in the
unlikely event of a failure, we recommended that both supplies are powered.

Audio Connections
The MixWizard uses professional grade 3 pin XLR, 1/4" TRS (3 pole) 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 most audio system problems are due to faulty or sub standard
interconnecting leads. The following plugs may be used to connect audio to the console:
Avoid reversing + and - on balanced connections as this will result in reversed polarity (out
of phase) signals which may cause signal cancellation effects.
Where long cables runs are required, balanced interconnections should be used. However,
line level interconnections between more affordable 2-wire (signal, ground) unbalanced
equipment and the console are unlikely to cause problems if the cables are kept shorter than
10 meters or so. Refer to the wiring diagrams on the opposite page.
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 potential differences exist between grounds at different
points in the system, and the signal has more than one path to ground. In most cases
ground loops do not result in audible problems. Should you experience hum or buzz caused
by a ground loop, 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 keeping the signal shielding down the length of cable.
WARNING For operator safety do not remove the ground (earth) 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, computer equipment and mobile phones. Where this cannot be
avoided, cross the cables at right angles to minimise interference
A note about balanced connections
A differentially balanced connection has two signal wires, signal + (hot) and signal - (cold)
and a shield. The signal source generates positive going polarity down the + wire and
negative polarity down the – wire. The destination input stage accepts the + signal on its
non-inverting (+) input pin, but it inverts the – signal, adding it to the + signal. The result is
that the wanted signal is boosted. Now examine what happens when unwanted interference
(hum and noise) is induced into the cable. The noise is induced equally and with the same
polarity into both wires. At the destination input the – wire signal gets inverted and added to
the + signal. Because the polarity is the same on both input wires the noise cancels itself
out at this input. For this interference rejection to work it is important that the source, the
cable and the destination input are all balanced. Balancing provides greatest advantage
with low level signals such as those produced by microphones.
An impedance balanced output provides similar interference rejection, but without the signal
drive on the - wire. It does not generate a negative polarity signal at its – output. Instead,
the – wire has no signal but is held at the same impedance as the + wire. This means that
both wires pick up the noise equally resulting in cancellation as described above.

XLR or the LINE TRS jack as the input source. The XLR is normalled
through the TRS jack. This means that the XLR can be used for
microphone or line level signals when nothing is plugged into the jack
socket. Both inputs are balanced but can be wired to work with
unbalanced signals when required.
WARNING: Do not connect unbalanced sources or cables to
the XLR input when 48V phantom power is selected. To avoid loud
clicks always turn the channel off by pressing MUTE when switching
+48V on or off, and when plugging or unplugging cables.
STEREO LINE IN The WZ314:4:2 has two stereo inputs for each of
the two stereo channels. ST1 and ST2 feed channel 11-12, ST3 and ST4
feed channel 13-14. All inputs use TRS jacks. ST1 and 3 are
unbalanced, ST2 and 4 are balanced, Unbalanced inputs automatically
connect the TRS ring to ground for working with balanced sources. The L
input is normalled through the R input to accept mono signals.
INSERT A single 3-pole TRS jack carries the unbalanced insert signal.
SEND

TIP
RING
Tip = send, Ring = return, Sleeve = common ground. The channel inserts
are post-HPF, pre-EQ and operate at 0dBu. The group (aux) and LR mix
inserts are pre-fader and operate at -2dBu. These should work fine with
line level signal processing equipment such as compressors, outboard
EQ, delay units and so on. An example of a suitable cable is shown here:
DIRECT OUTPUT The mic/line channel direct output is available on
an impedance balanced TRS jack. It is a line level signal operating at
0dBu. The source is set using an internal option jumper for each channel.
The factory default setting is pre-fade (following the pre/post-EQ setting).
This may be changed to post-fade if preferred.
The direct outputs provide a useful source for multitrack recording. Many
users prefer pre-fade sends for this application so that the live show fader
movements do not affect the recording which can be mixed later. Another
application is channel effects sends. For example, a reverb unit may be
dedicated to work with the lead vocalist channel only. Using a post-fade
direct output instead of an aux send frees up that aux mix for other
purposes.
WZ314:4:2 User Guide

GROUP (Aux), L, R, M OUT The main console mix outputs are on
balanced XLR. These produce +4dBu when the meters read ‘0’. The M
output can be switched to provide a mono sum of the post-fade L and R
signals, or the PFL/AFL engineer’s wedge output.
The L and R outputs typically feed the house PA system in live sound
mixing, or a 2-track recorder in studio mixing. In FOH mode, the M output
can provide an additional feed for a mono fill speaker or zone, or be used
as the main feed into a mono PA. In monitor mode the M output feeds the
engineer’s wedge monitor speaker with the AFL signal interrupted by PFL.
Group 1 – 4 outputs can be used to provide additional zone or special
feeds, or for multitrack recording. In FOH mode they are often left
unconnected where the groups are used as ‘subgroups’ for grouped level
control and/or inserted processing. In monitor mode, the group and LR
output XLRs and inserts become the aux mix masters. This configures the
console with 6 main mix outputs capable of driving the stage monitors.
AUX OUT 1-6 Each aux send is available on an impedance balanced
TRS jack operating at -2dBu line level. An internal option is available to fit
a balanced line driver IC to provide an electronically balanced output
operating at +4dBu. Note that it is not usual to require this option as the
impedance balanced standard drive provides sufficient interference
rejection when feeding balanced equipment inputs.
The aux sends are typically used to feed monitors, effects devices such as
reverb and delay, and for special mix requirements. In monitor mode,
these outputs reverse with the groups and LR connections.
MATRIX OUT A, B Each matrix output is available on an impedance
balanced TRS jack operating at -2dBu line level. An internal option is
available to fit a balanced line driver IC to provide an electronically
balanced output operating at +4dBu. Note that it is not usual to require
this option as the impedance balanced standard drive provides significant
interference rejection when feeding balanced equipment inputs.
The matrix outputs are typically used for stereo or mono recording or
broadcast feeds, delay and fill speakers, zone feeds, hearing assist loops
and so on.
2-TRACK IN and OUT These connections are unbalanced on RCA
phono sockets for connection to popular recording and playback devices
such as CD, MiniDisc, computers and tape machines. Nominal line level
is -2dBu. The 2-track SEND always follows the post-fade LR mix
regardless of mode switch configuration. The 2-track RETURN can be
used for monitoring a stereo recording, or as a simple stereo input for
playback of walk-in and background music.
MONITOR OUT
These impedance balanced line level TRS jack
outputs follow the post-level monitor signal. Separate sockets are
provided for the L and R signals. Use these to feed local speaker or other
in-ear monitor systems.
SYS-LINK II OPTION A blank plate is fitted here as standard. The
WZ314:4:2 Sys-Link II input/output option kit is available from Allen &

attenuates the input signal by 20dB for connection to high level
microphone or line sources.
GAIN Adjusts the input sensitivity to match the connected source to
the internal 0dBu operating level of the channel. Provides a variable
50dB range from +10 to +60dB gain (mic), or -10 to +40dB (line, pad
selected). The gain should be set using PFL so that the console
meters average ‘0’ with loudest moments lighting ‘+6’. Reduce gain if

AUX SENDS These rotary controls adjust how much channel
signal is mixed to the aux outputs. Each of the 6 auxes has its own
control. They adjusts from fully off to +6dB boost. Unity gain 0dB is
marked at 3 o’clock position. Auxes 1-4, 5-6 are switched pre/post.
These settings may be changed if preferred by repositioning internal
jumper link options. They offer many different combinations of pre and
post-fade sends, and a post-EQ option for the pre-fade sends. More
detail is provided in OPTIONS later in this guide.
Pre-fade aux sends are not affected by the channel fader movements.
These are typically used to feed stage monitors. In most cases users
also prefer that the monitor sends are not affected by inserted
processors or the channel EQ. Post-fade aux sends follow the channel
faders and are typically used to send a proportion of the channel signal
to an effects device such as reverb or delay. Note that post-fade
sends may be preferred when the console is configured in monitor
mode so that the faders become ‘masters’ for all monitor mixes. Pre or
post-fade sends may also be used for special applications such as
recording, zone feeds, clean feeds and aux fed subs.
PRE When pressed, the pre-fade channel signal is sent to the
associated auxes. When released, the post-fade signal is sent. Auxes
1 to 4 and 5, 6 are grouped for pre/post switching. You can change
this by repositioning the internal option jumpers.

Note that this becomes the group mix in monitor mode. The console
main meters are interrupted with the aux (group) signal. The yellow
indicator lights to show that AFL has been selected on the master.
Use AFL to check the signal being sent to the monitors, effects or other
destination.
REV These switches reverse the function of the group and aux
masters. They are recessed to prevent accidental operation. Use a
pen or pointed object to set their position. In the up position (flush with
the panel), the group is controlled by the fader and the aux by the
rotary master. This is typical for FOH mode where the faders are used
for subgroups feeding the main stereo mix. When pressed, the aux
uses the fader as the master and the group is moved to the rotary
control. The aux mix is now presented to rear Group XLR complete
with insert. The group mix appears at the Aux TRS jack. This is used
for monitor mode where the auxes are the main mix feeding the stage
monitors. You can select any combination for the FOH and monitor
mode, for example, just 3, 4 giving you two fader subgroups, two
monitor sends on faders, and main LR mix.
Note: The groups always feed the matrix and the subgroup controls
(PAN and GRP TO LR) regardless of mode. This means the group
mix can still perform a useful function when the console is configured
in monitor mode.
PAN Positions the group signal between L an R in the stereo mix
when the GRP TO LR switch is pressed. Using pan you can create
mono or stereo groups positioned as you require in the main mix. For
stereo grouping, set the odd group pan fully to the left, and the even
group pan fully to the right. The centre position (mono image) is
detented for quick resetting. Note that the group mix always feeds
these subgroup controls regardless of FOH or monitor mode selected.
METER

Console Monitor Comprehensive engineer’s headphones and
local monitoring is provided.
Select either LR or 2-track return as the default source using the L-R /
2TRK switch. Pressing PFL or AFL elsewhere on the console
automatically overrides the current monitor source with the signal from
the channel or mix selection. The red PFL/AFL active indicator
illuminates and the console meters display the active signal.
The console main meters provide 12 LED indicators to accurately
display the signal level of the selected monitor source. Reduce the
signal level if the red ‘+16’ peak indicator lights. For optimum
performance the signals meter an average ‘0’ with loudest peaks
reaching around ‘+6’.
Use the MONITOR level control to adjust the level in the headphones
and local speaker monitor. We recommend you use closed ear
headphones in the range 30 to 600 ohms designed for live sound
monitoring. Headphones around 100 ohms impedance are a popular
choice.

MATRIX The matrix provides 2 additional console outputs. It is a
‘mixer within a mixer’ taking its source from the groups and main mix.
It can be used to provide duplicate main outputs or to create new
mixes from the main outputs. The controls are positioned conveniently
away from the live performance controls to avoid accidental operation.
Each of the 4 groups, L and R can be mixed independently into the
matrix. The source is derived post-fader. Adjust the level clockwise
from fully off to +6dB boost. Use the LEVEL control to adjust the
matrix output level from fully off to a maximum boost of +6dB. The
‘0dB’ positions are marked. The matrix output can be muted. The
post-level signal can be monitored using the AFL switch.

Use the matrix to create special mixes such as delay, fill and zone
speakers, recording and broadcast feeds, hearing assist loop and so
on.

User Options
The MixWizard has a versatile architecture which
should satisfy most applications you may encounter
without modification. However, the following internal
options provide alternative settings for those
applications that may demand them. Access is
required to the internal assemblies.
For user
convenience, pluggable jumper links are used in
most places.
REMOVE 4x M4 POZI SCREWS PER SIDE
REMOVE SIDE TRIMS
REMOVE M4 POZI SCREW PER SIDE
ROTATE POD
Remove the base Start by removing the side
trims if fitted using a Pozi crosshead screwdriver.
Release the two M4 Pozi head pod securing screws
and rotate the connector pod to gain access to the
three M3 rear base fixing screws. Use a Torx
starhead screwdriver to remove these. Rotate the
pod again to remove the four M3 underside base
screws using the Torx driver. Carefully lift off the
base.
REMOVE 3x M3 TORX SCREWS
Configure the internal options
Fit the
options required. Set the option jumpers to the
required positions. Make sure they are pressed fully
home. Check that all channels are correctly set and
all options fitted according to their instructions. Make
sure that no debris or parts are left loose inside the
console.
ROTATE POD
REMOVE 4x M3 TORX SCREWS
Refit the base
Carefully reposition the base.
Refit the fixing screws. Lock the connector pod in
the required position using the securing screws.
Refit the side trims if required.
LIFT OFF BASE
IMPORTANT:
Check carefully that all channel
jumpers are correctly set as required. Errors on one
or more channels now may cause user problems
later. We recommend that you write the repositioned
jumper settings on a label and adhere this to the rear
panel. This would provide a helpful reference to
other users of the console.

PRE-INSERT/POST-EQ
the mono channel pre-fade auxes is pre-insert, preEQ. This is popular with many users mixing monitors
from FOH. It prevents the channel EQ and inserted
compressors affecting the monitor mix. Move the
jumper from A to B to change this to post-insert,
post-EQ if preferred. Note that auxes are always
post-mute.

Factory default is prefader.
This is common for live recording to
multitrack. The live mix fader movements do not
affect the recording. Move the jumper from C to D to
change to post-fade. Post-fade is appropriate when
using the output as a direct channel effects send.
Channel Aux pre/post settings
Factory
default is Aux 1-4 = switched, Aux 5-6 = switched.
You can change these settings for different
combinations of pre/post or switched auxes by
repositioning the links. Refer to the system block
diagram to explore the possibilities. Make sure you
set all mono and stereo channels the same. We
recommend you only change these settings if
absolutely necessary.
Stereo/Mono aux source
The stereo
channels can feed the auxes with a mono sum of
L+R, or be configured so that L feeds the odd
numbered auxes, and R the even. This is preferred
when using odd/even auxes as stereo pairs. Factory
default is the mono setting.
PRE-FADE AUXES
Talkback mic +48V
The factory default is
+48V phantom power turned on for the front panel
talkback mic XLR input. The option jumper is behind
the TB mic XLR on the L Master board. If you prefer,
phantom power can be disabled by repositioning the
jumper to the GND position.

Note that phantom power should not harm nonpowered dynamic microphones as long as balanced

WARNING: Do not connect unbalanced
sources or cables to inputs with phantom power
selected. To avoid loud clicks do not press the
TALK switch when plugging or unplugging the
talkback microphone.

BALANCE
Output balance options The aux and matrix
outputs are impedance balanced as standard
operating at nominal -2dBu and with +21dBu
maximum drive. They provide similar interference
rejection to electronically balanced outputs when
connected to balanced equipment inputs.
An
electronically balanced option is available if you
require nominal +4dBu and higher output drive up to
+26dBu over very long cable runs. However, it is not
usually necessary to fit this option as the impedance
balanced drive satisfies most applications. Check
that you really need the option before fitting it.
There are two balanced driver ICs which may be
used. Either is suitable. These are available from
Allen & Heath or most electronic component
suppliers. The Allen & Heath part number is shown
below:

For each aux master, snip the legs of the two zero
ohm resistor links next to the IC socket. This
removes them from the circuit. Now simply plug the
option IC into the socket. Observe the correct IC
pin1 orientation and make sure its legs are correctly
aligned with the socket. Test the output once the
work is complete. You should measure the same
level but opposite polarity signal between + (hot) and
ground, and – (cold) and ground.
Sys-Link II input/output option A blank
plate is fitted here as standard. This may be
replaced with an optional card which provides the
console inputs, outputs and PFL system on two
37way D connectors for linking to other Allen &
Heath consoles already fitted with Sys-Link II. The
WZ314:4:2 can become an input channel expander
(slave) or have its number of input channels
expanded (master) when linked to other consoles.
A 37way shielded multi-core cable carries the
MixWizard balanced mix signals and PFL system to
or from the other console.
