Introducing the MixWizard WZ314:4:2

The Allen & Heath MixWizard series of consoles includes several models. This user guide
describes the WZ

3

14:4:2 4 group model. The 2 bus WZ312:2 and WZ316:2, 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 WZ

3

14:4:2 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 WZ

3

14:4:2 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.

Connecting Power

EXTERNAL DC IN

BACKUP SUPPLY

ONLY USE RECOMMENDED ALLEN&HEATH POWER S UPPLY.
REFER TO USER GUIDE FOR DETAILS.

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.

CAUTION

WARNING: THIS APPARATUS MUST BE EARTHED

ONI0OFF

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.
