WZ12:2DX
With 8 mono inputs and 2 fully featured
dual stereos, this latest addition to the
range provides all the professionalism of its
sister consoles at a new lower price point.
Like the WZ16:2 DX, the WZ12:2 DX comes
complete with onboard digital effects.
WZ16:2DX
When we held the first design meetings for the MixWizard series, we had a very
clear goal in mind - to create a range of compact mixers with big features, great
sound and totally professional build quality. The phenomenal sales that the
MixWizards have enjoyed tell me that we got it right.
Now the best has got even better. We’ve looked at the areas where we could
improve on the existing MixWizard designs, adding useful features such as a Pink
noise generator for the WZ14:4:2+ and onboard FX for the other models. We’ve
listened to your requests for metal jacks and channel on led’s - you’ll now find
these on all MixWizards. Internally, we’ve changed the way the circuit boards are
connected to make servicing even easier, and we’ve created a new universal input
heat reducing power supply.
There’s even a completely new MixWizard, the WZ12:2DX, which offers the same
commitment to quality and attention to detail that have made its sister consoles
such a big hit, but at an even more affordable price point.
I hope that you get as much enjoyment from using the new improved MixWizards as
we have had in designing them.

Building on the unprecedented success
of the original WZ16:2, the new model
has the same winning features for the
broadest range of applications, plus a
host of new assets, including onboard
dual effects processor, channel on LEDs
and more.
WZ14:4:2+
A truly versatile 4 group console with
mode switching for front of house and/or
monitoring applications, plus extensive
recording capability. New and upgraded
features include a switchable 1kHz
oscillator/pink noise generator and
individual phantom power switching.
QCC
MSP
Build Quality
Allen & Heath’s unique Quick
Change Connector system
allows reconfiguration of all
MixWizards for desktop, rack or
flightcase mounting. Unlike
many similar systems, QCC is
quick and convenient to use your MixWizard can be changed
from desktop to rackmount
format and back, in just a
couple of minutes.
Any signal processing will
inevitably change the original
sound - even sending a signal
down a wire will have a minute
influence. The crystal-clear
MixWizard sound is achieved by
Allen & Heath’s MSP (Minimum
Signal Path) electronic design,
wide-band flat response
amplifiers, top-grade low noise
components and solid
grounding. Your ears will know
the difference.
The MixWizards feel professional
because they are professional and they are built to last.
All rotary controls are securely
bolted to the front panel - so the
rugged all-metal chassis takes
the weight of any impact. Each
input and master output has its
own vertically mounted circuit
board for rigidity and ease of
service or modification.

WZ14:4:2+ becomes a dedicated
monitor console by activating
tamperproof mode switches. The aux
and group/LR feeds are swapped
over, giving XLR outs, inserts for
graphic EQ’s and 100mm fader
controls to all 6 aux mixes.
In Dual Mode, as many auxes and
groups are swapped over as
required, allowing all mixing
functions to be provided by a single
engineer and a single console.
Engineer’s Monitoring
LR output is monitored via 12
segment peak reading bargraph
meters, and by the headphone
socket (complete with independent
level control). PFL/AFL selections
override the LR feed, illuminating a
warning LED.
Groups and LR are also monitored
by a bank of six additional 4
segment level meters, allowing
output level monitoring even when
PFL/AFL is selected.
WZ14:4:2+
The LR mono sum is fed to a
balanced XLR output with level control
for broadcast feeds, F-o-H fills etc.
In monitor mode, the mono out can
be used to feed an engineer’s wedge
with any AFL/PFL signals.
Output Masters
Groups can be panned to the LR as
well as having their own outputs.
Signals are sent to the balanced XLR
outputs via the faders, on and AFL
switches. All XLR outputs have
inserts and peak reading meters.
In monitor mode, signals are sent to
the balanced jack aux send outputs,
via their level controls and AFL,
whilst benefiting from all master
output features.
Talkback to Auxes
A talkback mic can be connected via
a front panel XLR socket, allowing
talkback to auxes in selected pairs.
Oscillator & Pink Noise Generator
A 1kHz signal can be routed through
level controls and meters to 2-track
recorders for level alignments. A
pink noise generator allows checking
of frequency response and phase
connections for speaker arrays.
CONNECTIONS
Apart from the headphone and talkback plugs on the front panel, all connections are made to the QCC panel which can be swung and fixed for rear or back orientation.

Monitor Select Switchbank
Mono and Stereo Aux
Monitoring
WZ16:2DX and WZ12.2DX’s unique monitoring
system allows headphone monitoring of a single
aux or to a pair of auxes in stereo for stereo
monitors and recording feeds.
Bargraph Meters
Twin 3 colour, 12 segment bargraph
meters follow the selected monitor
source.
PFL
A red LED lights when PFL is
selected, as PFL overrides all other
monitor sources.
Headphones
Monitor source signals are fed to the
stereo headphone jack via an
independent phones level control.
A column of switches gives quick
selection of monitor and meter
sources. Fed post-master level, the
aux signals can be selected individually
for mono listening or in pairs for
stereo and balance checks. Stereo
returns are selected in stereo pairs.
AB Out
WZ16:2DX and WZ12.2DX features
an innovative independent stereo or
monoed output. The AB out can be
fed from the L-R mix pre or post
fader, or from the selected monitor
source. As it offers its own level
control, this versatile output can be
used to feed a 2-track recorder,
broadcast line, speaker fill, studio
monitors, engineer’s wedge or
employed for any number of other
special applications.
effects
When you need effects, the WZ16:2DX and
WZ12:DX offer a quantum leap of
performance. The dedicated on-board digital
effects processor can be configured as a
single stereo effect or two independent stereo
effects, allowing you to select from 32 (yes,
thirty two!) effects. Combined with the two
stereo effects returns channels, this gives you
up to four stereo effects in your mix without
tying up valuable channels as effects returns.
Allen & Heath has carefully selected the
algorithms for the effects processor. In Single
Mode, the processor is driven from Aux 5 with
16 different effects programs available. In
Dual Mode, processing is provided on both
Auxes 5 and 6, with 8 independent programs
available on each. Whichever mode you
WZ16:2:DX & WZ12:2:DX
choose, the effect returns to the mix via FX
return channel ST1. External effects can also
be mixed into this channel via the dedicated
jack connectors. Auxes 5 and 6, can still be
used as conventional aux sends to drive
external processors or foldback amplifiers.
The MIDI IN socket on the rear panel provides
program change capability via MIDI and also
enables presets to be edited using an external
computer.
