WZ312M User Guide
Introducing the MixWizard WZ312M
The Allen & Heath MixWizard WZ312M Is a dedicated monitor console. With 16 mic/line
channels feeding 12 mixes in a compact 19” rack mount frame it is ideal for personal
monitoring systems touring with a show or installed on stage where space is tight.
Each of the 16 mic/line channels features a 4 band semi-parametric EQ, high pass filter, 12
mix sends globally switched in pairs for mono or stereo operation, individual phantom power,
rotary channel trim control, mute and PFL monitoring. Each of the 12 mix masters includes
a fader, mute and AFL monitoring, stereo mode selector, insert and differentially balanced
XLR output. Channel and mix master inserts can be used for patching in outboard signal
processors such as compressors, noise gates and graphic EQ. Comprehensive metering
and stereo/mono PFL/AFL headphones/local monitoring, external monitor input, dual
redundant backup supply input, and a lamp socket are provided. An option is available to
link two consoles together to expand the number of inputs to 32.
The WZ312M features a built-in XLR mic splitter. This means that inputs can be plugged
into the console on stage and simultaneously linked to the multi-core feeding the front-ofhouse console without the need for an external mic splitter.
The MixWizard Series is built with individual circuit cards, potentiometers nutted to the panel
for absolute strength, an all 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 rotated for rear facing or underside connectors
when rack mounted.
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, powered speakers and in-ear systems 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 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.

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.
BUILT-IN MIC SPLITTER A passive splitter passes each channel
XLR input directly through to an XLR output to send the signal to another
console such as Front-of-House or recording. The mic signal can feed the
monitor and the FOH console at the same time. Connect the split outputs
to the multicore feeding the FOH console using XLR cables.
NOTE: Phantom power can be switched from either the monitor or
the FOH console. If switched from FOH then make sure GND LIFT is
not selected. If it is necessary to select GND LIFT then phantom
power should be switched from the monitor console. No harm will be
done to the consoles if phantom power is switched from both
consoles at the same time.
GND LIFT Disconnects the pin 1 ground connection between the input
XLR and the split output XLR. Press this if there is a problem with a
venue ground loop causing audible hum when connecting the splitter to
the second console. A single ground lift switch is provided next to CH1
input. This affects the ground connection to all the channel split outputs.

insert signal. Tip = send, Ring = return, Sleeve = common ground. The
channel insert is post-HPF, pre-EQ and operates at 0dBu. Use these to
patch in line level signal processing equipment such as compressors,
gates or outboard EQ. The wiring of a suitable cable is shown in the
diagram:
MIX INSERT Each mix is provided with an insert socket for patching in
an outboard signal processor. When working with stage speakers this is
typically a 31 band graphic or a multi band parametric EQ used for ringing
out feedback or tuning the speaker response. When working with in-ear
systems this may be a dynamics processor with limiter to protect the in-ear
user’s ears from unexpected signal peaks. AFL monitors the signal after
the insert so that the engineer can listen to the effect of the processor. A
single 3-pole TRS jack carries the unbalanced insert signal for each mix
output. Tip = send, Ring = return, Sleeve = common ground. The insert is
pre-fader and operates at a nominal -2dBu line level.
MIX OUT The 12 mix outputs are provided on balanced XLR, pin 2 hot.
These produce +4dBu when the meters read ‘0’. The mix outputs feed the
stage monitors, typically wedge loudspeakers and in-ear personal
monitoring systems. They can also be used as effects sends, recording
feeds and for other special requirements.
MONITOR OUT The console stereo monitor is simultaneously sent to
the headphones amplifier, a pair of balanced XLR outputs and a pair of
impedance balanced TRS jack outputs. The XLR output operates at
nominal +4dBu, the TRS jack at -2dBu. The XLR and jack outputs can be
connected to the engineer’s local speaker or in-ear monitoring systems.
The output may be switched for mono or stereo operation.
HEADPHONES OUT The console is provided with two headphones
sockets on the front panel – a ¼” TRS jack and a mini 3.5mm jack for
plugging in standard headphones or monitor ear pieces similar to those
worn by the performers.
EXT IN Unbalanced ¼” jacks, 0dBu line level signal. Feeds the stereo
AFL mix when switched on. For mono signals, plug into the left input only.
Use this input to add an external signal such as the monitor output from an
in-ear transmitter rack or remote talkback to the engineers monitor.
USER OPTION Blank plates are fitted here as standard. The SysLink II console expander option kit may be fitted here.

Switches in the channel high pass filter. This attenuates
frequencies below 80Hz by 12dB per octave. The filter is pre-insert,
pre-EQ. Select the HPF to reduce low frequency noise such as
microphone popping, stage noise and tape transport rumble.
EQ A 4-band semi parametric EQ provides independent control of
four frequency bands. HF and LF are shelving filters which affect high
frequencies above 12kHz, and low frequencies below 80Hz
respectively. HM and LM are bell shaped peak/dip filters which affect
frequencies around a centre point which can be swept from 500Hz to
15kHz and 35Hz to 1kHz respectively. These have a width (Q) of 1.8.
All bands can be boosted or cut by up to 15dB and have a centre
detent 0dB position.
Check for the best microphone selection and placement before using
the EQ. Start with the EQ set flat and apply only as much boost or cut
as is really needed. When dealing with problem frequencies cut rather
than boost where possible.

Stereo or Mono Odd/even pairs of mixes can be configured for
mono or stereo operation by setting a recessed mode switch near the
master faders. In MONO mode two independent sends are available.
In stereo mode, the odd numbered send becomes a stereo level

adjustment to compensate for a change in source level, to make a
quick level change affecting all mixes, or deal with a problem such as
feedback. Alternatively you could use it to create a starting point mix
for several monitors. For normal operation, start with CH TRIM set to
its 0dB (unity gain) position (3 o’clock – marked with an arrow).
PFL Press PFL to listen to the pre-trim channel signal in the

that channel. Selecting more than one PFL at the same time mixes
those signals together in the monitor.
PEAK

SIGNAL The green signal presence indicator lights when the mix
post-fade, post-mute signal is greater than -12dBu.
STEREO mode switch
Pressing the switch configures the
related odd/even numbered mixes for mono or stereo operation. In
MONO mode (switch flush with panel), two independent mono mixes
are provided. In STEREO mode (switch below the panel), the top (odd
numbered) channel send becomes the stereo send level control, and
the lower (even numbered) control becomes the pan control to position
the signal between L and R within the stereo image. The switch is
recessed below the panel to protect it from accidental operation. Use
a pen or pointed object to change the setting.
FADER A 60mm fader provides accurate control of the mix output.
Boost of +10dB is available above the nominal ‘0’ position. For normal
operation the fader should be operated around its ‘-10’ to ‘0’ position.
If the fader needs to average higher or lower than this check the gain
structure between the console and the connected equipment.

The Engineer’s Monitor
The console provides left and right engineer’s monitor outputs on XLR and TRS jacks. The
monitor signal is also fed to a built-in headphone amplifier with ¼” and 3.5mm output jacks.
An AFL (after fade listen) function is provided to monitor the mix output signal. This is
interrupted by pressing a channel PFL (pre fade listen) switch. An external input lets the
engineer add an external stereo signal such as in-ear transmitter monitor output or talkback
feed to the AFL mix.

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.
Using the Meters The MixWizard provides metering of inputs and outputs.
For best results 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
send levels to prevent unexpected loud volumes reaching the 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 monitor.
Once the channel gain is correctly set you can raise the send 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.
