General Precautions
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 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. The fader and potentiometer knobs may be removed for cleaning with a warm
soapy solution. Rinse and allow to dry fully before refitting them.
Transporting :
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.
Hearing :
To avoid damage to your hearing do not operate any sound system at excessively
high volume. This also applies to any close-to-ear monitoring such as headphones.
Continued exposure to high volume sound can cause frequency selective or wide
range hearing loss.

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.
3. 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.

Audio Connections
The MixWizard uses professional grade 3 pin XLR and 1/4" TRS (3 pole) jack 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 mating plugs may be used to connect audio signals 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.

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.

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 AUX6 output.
The L and R outputs typically feed the house PA system in live sound mixing, or a 2track recorder in studio mixing. In mono 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.
Used with a mono PA the L and R mix can provide a pair of subgroups, each with routing using the channel PAN controls, inserts and faders. Configured to provide the
AUX6 mix, the M output is ideal for driving a sub bass speaker system when working
with an ‘aux fed subs’ PA. This provides the sub feed with its own per-channel mix on
balanced XLR and with dedicated fader alongside the main LR faders for proper control
of the house volume.
AB OUT A pair of impedance balanced TRS jacks can be configured to provide an
additional LR mix or engineers monitor send. These operate at -2dBu line level. A
front panel recessed ‘mode’ switch determines the source to the AB output. This may
be set to follow the console monitor system and therefore feed an independent local
stereo monitor or even engineers wedge speaker. When set to follow the LR mix, the
factory default source is taken post LR fader. An internal option jumper is available to
change this to pre LR fader.
The unique AB output feature provides the MixWizard with a host of possibilities…
independent 2-track recording feed, broadcast feed, zone and delay fill feeds, local
monitor, engineers wedge monitor and more.
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 significant interference rejection when feeding balanced equipment inputs.
The aux sends are typically used to feed stage monitors, effects devices such as reverb
and delay, and for special mix requirements.
Footswitch
FOOTSWITCH Mutes and unmutes the ST5 (ST1) effects return channel, ideal for
bypassing the effects between songs. Note that this affects the internal processor and
also any external effects device that may be plugged in to these return inputs. Use a
momentary or latching footswitch as required. Shorting a TS or TRS jack tip to sleeve
turns the mute on.

Important note on setting channel levels: Use PFL to set the GAIN
controls for correct signal level through each channel. Use the faders to
balance each signal in the mix. These are typically operated around their -20

They provide +10dB boost above the nominal ‘0’ position. For best performance
the faders should be operated around the ‘0’ position for normal ‘loud’ level. If
you find yourself operating significantly below ‘0’ then the amplifier or other destination equipment is too sensitive for the console +4dBu output. Simply turn
down the amplifier or equipment level trim. If none is available then insert an
attenuator pad between the console and connected equipment. Operating the

Aux master To use the M output as the AUX6 master press the switch using a
pen or pointed object. Use the post-fade AUX6 channel sends to mix the required signals to the M output. This provides a main console output with its own
mix bus. Typical applications include:
Dedicated MONO mix The output feeds a centre mono fill speaker system,
for example above the proscenium arch or along the front of the stage in a theatre. You may wish to feed just a few of the sources to these speakers, for example just the radio mic channels for front row clarity. Using the aux send allows
you to create the required mix balance and have proper master fader control.
AUX6
Aux fed subs This increasingly popular application drives the sub bass speakers
with their own mix. It lets you send only those sources with wanted low frequency information to the sub speakers. It can dramatically clean up the mix as nonbass channels such as vocals and guitars are kept out of the subs and therefore do
not allow low frequency pickup to muddy the mix. It is typical to include only
sources such as kick drum, bass guitar, keyboards and sound effects to these
speakers.
The unique MixWizard aux mode feature puts the master control of the sub mix
on to a fader next to the main LR faders. This means that the house volume can
be controlled without upsetting the balance between LR and sub speakers. The
feed to the sub speaker system is on balanced XLR, and it can be monitored by
selecting the M switch in the headphones monitor section.

WZ4 16:2 and 12:2 User Guide
Gain Structure
How the levels between the different signal stages are set up is referred to as the gain structure.
For best performance it is important that the connected source signals are matched to the ‘normal
operating level’ of the console. Similarly the levels of the connected amplifiers and destination
equipment should be correctly matched to the console outputs. If set too high then the signal
peaks will be clipped resulting in distortion, and if set too low then the signal-to-noise performance will be degraded resulting in excessive background hiss and noise.
sults operate the console with the main meters averaging around ‘0’ allowing the loudest moments
to reach ‘+6’. Reduce the channel gain settings if the red peak indicators start to flash. Note that
the peak indicators light 5dB before actual clipping to warn that you are nearing distortion and
should reduce gain. The LED bar meters have a ‘quasi-peak’ response with fast attack and slow
release so that fast musical transients are accurately displayed.
Matching a Source to the Console Start by turning down the channel fader and send
levels to prevent unexpected loud volumes reaching the main speakers and monitors. Using PFL,
adjust the GAIN control for an average ‘0’ reading on the console meters. These automatically
switch to show the channel pre-fade signal when PFL is pressed. Listen to the signal using headphones or local AB monitor. Once the channel gain is correctly set you can raise the levels to
bring the channel into the mix. Note that you may need to adjust the gain if you make significant
changes to the EQ. Make sure that any equipment inserted into the channel is set to operate
around 0dBu line level. First set the gain with inserted signal processors such as compressors
switched to bypass.
Matching the Console to Destination Equipment The console produces a
standard XLR output level of +4dBu for a meter reading of ‘0’. It can produce a maximum of
+26dBu which is more than is usually required and therefore gives you plenty of headroom. If you
are connecting to a sensitive power amplifier it is advisable to turn down its input trim control if
the normal console level is too high. Simply turning down the console output faders degrades the
output stage noise performance and reduces the resolution of the fader movement. The output
faders are best operated around ‘-10’ to ‘0’ for loudest average volume required. This allows additional headroom if you need it.
Terminology The normal operating level is the optimum signal level for best console performance, indicated by ‘0’ meter readings and resulting in the +4dBu XLR output level. The channels
operate at 0dBu and the mix stages at –2dBu for extended headroom. Headroom is the extra
level available above normal to allow for loud peaks before the signal becomes clipped resulting in
audible distortion. The signal-to-noise ratio (SNR) is the difference measured in dB between normal level and residual noise floor (hiss) produced by the console electronics. The dynamic range is
the sum of headroom and SNR representing the maximum signal range possible from quietest to
loudest.
Final word… A little care with setting gain structure throughout the signal chain will give you
the best performance and most manageable control of the mix.

REMOVE 4x M4 POZI SCREWS PER SIDE
REMOVE SIDE TRIMS
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. pluggable jumper
links are used in most places and also some links require cutting and soldering
a solder bridge.
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.
USO RESTRITO
REMOVE 3x M3 TORX SCREWS

Jumper 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
Solder Options:
Solder options require some ability with a soldering iron, if you have any reservations then please contact your local service centre to carry out this procedure for you.
See page opposite for details on how to modify the solder options.
Refit the base Carefully reposition the base. Refit the fixing screws.
LIFT OFF BASE
Lock the connector pod in the required position using the securing screws.
Refit the side trims if required.
IMPORTANT: Check carefully that all channel options are correctly
set as required. Errors on one or more channels now may cause user problems later. We recommend that you write the repositioned option settings
on a label and adhere this to the rear panel. This would provide a helpful
reference to other users of the console.

Factory default is pre-fader. This is
common for live recording to multitrack. The live mix fader movements
do not affect the recording. Move the jumper from PR to PO to change
to post-fade. Post-fade is appropriate when using the output as a direct
channel effects send.

Factory default for the mono chan-

mixing monitors from FOH. It prevents the channel EQ and inserted
compressors affecting the monitor mix. Move the jumper from PR to PO
to change this to post-insert, post-EQ if preferred. Note that auxes are
always post-mute.

Factory de-
fault is Aux 1-2 = pre-fade, Aux 3-4 = switched, Aux 5-6 = post-fade. You
can change these settings for different combinations of pre/post or
switched auxes by cutting and resoldering the links. Refer to the system
block diagram to explore the possibilities. Make sure you set all mono
and stereo channels the same. Before you make your choice, consider
whether you want to use AUX5 or 5/6 for the internal effects (should be
post) and/or AUX6 to feed aux fed subs (also post). We recommend you
only change these settings if absolutely necessary.
Solder Options: Cut tracks with a sharp knife and ensure that any
cuts don't extend beyond the marked area. Add a solder blob to connect
the adjoining pads. If you have any doubts about this procedure please
contact Allen & Heath and we will put you in touch with your nearest
service centre.

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. Note that you
should also set the ST1 (ST5) stereo/mono jumper to the same position.
Effects return stereo/mono aux source
The return
channel ST1 (5) feeds Auxes 1-4 with a mono sum of the stereo signal. If
you are working with stereo auxes you can reconfigure this for stereo
with L feeding Auxes 1, 3 and R feeding Auxes 2, 4.
AB source pre or post LR faders
The factory default is
that the post-fade LR mix feeds the AB output. If you prefer the master
LR faders not to affect the AB output then reposition the two option
jumpers in the PRE position. This may be desired if you are using the AB
output to feed a 2-track recording independent of the house level.

AUX master balance option
The 6 aux
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.

For each aux master, snip the legs of the two zero ohm
resistor links as shown. This removes them from the
circuit. Now solder 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.
