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 WZ414:4:2 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 WZ414:4:2 has 10 mono mic/line inputs, 2
fully featured dual input stereo channels and a 2track 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 and a lamp socket.
The base of the console can be removed to access internal user selectable options. 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 an optional USB2 output card
which allows the console to be linked to a computer for multitrack recording.
An Allen & Heath LEDlamp gooseneck lamp with
built-in dimmer can also be added for lighting the
console in low light conditions.

14:4:2 User Guide
Installing the Console
Free Standing
The console is supplied ready for free standing operation with its side trims fitted and connector pod positioned for
rear access. If you are converting from rack to free standing then make sure the pod is correctly rotated and secured, and the side trims fitted as shown:
19” Rack Mount
For rack mounting, remove the two side trims and rotate the pod into the connector position preferred. Allow
enough space for the cables and connectors behind the console.
Do not transport the console with its connector pod securing screws removed. Do not attempt to remove the connector pod from the console. Do not obstruct the ventilation slots. Allow adequate space
around the console for air flow. If the side trims are to be removed, do not refit their fixing screws to the
unit. Retain and store these in case the trims need to be refitted in the future.

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.

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.

+48V
Switches +48VDC to the channel input XLR for powering microphones or DI boxes that need phantom power. The power is current
limited through 6k8 ohm resistors to pins 2 and 3.
WARNING: Do not connect unbalanced sources or ca-
bles to inputs with phantom power selected. To avoid loud
clicks always mute the channel before switching +48V on or off
and when plugging or unplugging microphones.
PAD (LINE)
Press this switch to select the channel TRS jack LINE
input. Release the switch to select the XLR MIC input. The XLR normals through the TRS socket. With nothing plugged into the line input
the switch therefore becomes a PAD for the mic XLR. It 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 the red peak indicator
lights.
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. We do not recommend setting
the faders to ‘0’ and mixing using the GAIN controls.
HPF
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. Use EQ IN to compare the sound with the equaliser switched in or out of circuit. 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.

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.
WARNING: To avoid damage to your hearing do not operate
any close-to-ear monitoring such as headphones for long periods at
high volume. Continued exposure to high volume sound can cause
frequency selective or wide range hearing loss.
AUX 5 and 6 Masters
for auxes 1 to 4. The REV switch reverses the AUX5 mix with L, and AUX6
mix with R for operation in monitor mode. When selected, the aux signals are
presented to the L and R XLR outputs complete with their inserts. The LR
mix swaps on to the Aux TRS jack outputs. Note that the LR mix always feeds
the matrix regardless of mode selected.
M Master
XLR. The source is selected using the mode switch above the control. This is
recessed to prevent accidental operation. Use a pen or pointed object to set
the position. In the up position (flush with the panel), the post-fade L and R
mix is summed to provide a mono source. Use this in FOH mode to feed a
mono PA, fill, delay or zone speakers, or even a mono broadcast or recording
send.
In monitor mode, press the switch to create an engineer’s monitor wedge feed
from the AFL/PFL mix. It is common to use a wedge speaker of the same type
used on stage to listen to and check the various monitor mixes being sent to
the performers. Together with the group/aux REV function, the WZ414:4:2
can be configured as a compact yet fully featured monitor console.
LR Masters
They provide +10dB maximum boost. Each master includes a 4 LED bar meter, an AFL switch and a MUTE switch so that L and R can be separately monitored and muted. This is most useful in monitor mode where these masters
carry the AUX5 and AUX6 signals.
A rotary control adjusts the level of the signal to the M output
Separate faders control the main mix L and R output levels.
These function in the same way as described

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 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.
Configure the internal options
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.
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.

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.
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.

Aux pre/post insert / EQ
Factory default for the
mono channel pre-fade auxes is pre-insert, pre-EQ. 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.
Direct output source
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 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
JS8
JS7
these settings for different combinations of pre/post or
switched auxes by cutting and re-soldering the links. Refer to
SW
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.
Solder Options:
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.
