Allen & Heath WZ412:2 User Manual

The MixWizards have been designed with the same commitment to professionalism and detail that has made Allen & Heath a
leading name in larger format mixing consoles for nearly 30 years. Thousands of PA rental companies, touring and recording
artists, systems contractors, houses of worship and clubs are already enjoying the benefits of the MixWizard Series.
Now the series offers even more, with a host of added and upgraded features across the range, further establishing the
MixWizards as the choice in high specification compact mixers. In the way they sound, the way they perform and
in their construction, nothing compares with the MixWizard Series.

QCC
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.
MSP
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.
Build Quality
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.
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.
WZ12:2DX
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.
WZ16:2DX
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.

MixWizard
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.

4 Stereo Returns
Total of 8 possible fx returns (excluding the 2-
track return) on paired 1/4” jacks.
Returns can be fed to corresponding auxes (return 1 summed to aux 1, return 2 to aux 2 etc.). Each return can also be fed to the LR.
PFL switch and warning led.
Dual Functionality
WZ14:4:2+ excels as a F-o-H console, as a Monitor mixer, or as a combination of the two.
In F-o-H mode the 4 groups and LR feed auditorium speaker arrays, delay systems, dressing rooms, foyers etc, whilst the aux sends provide local monitors and fx.
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.
In monitor mode, the 4 segment meters monitor auxes 1-6, whilst the main 12 segment bargraph follows auxes 5 and 6.
2-Track Send and Return
Separate phono connectors and level trims are provided for 2-track recording from the LR mix. Selecting the LR replay button routes this signal to the LR mix for intermission replay.
Mono Output
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.

Aux Master Sends
Each of the 6 aux mixes has its own master level control. Up to 4dB boost is available to the impedance balanced output jacks.
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.
Monitor Select Switchbank
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.
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
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.

Stage Monitor
Typical amateur dramatics set-up with delay speakers compensating for acoustic delay and improving clarity to the rear of the hall. CD intermission replay, 2-track recording for the performers.
This example shows 4 floor wedges for the musicians and a stereo in-ear monitor for the lead performer. The engineer monitors the signals using a floor wedge similar to the stage monitors.
Multi-speaker system utilises the Left, Mono and Right outputs in conjunction with group outputs. Aux capability provides for FX and foldback requirements.
6 unique on-stage mixes are created. Insets allow graphic EQ’s to control each mix. The engineer uses the mono output to check on-stage sound.
Increasingly sophisticated sound control is required. Here, a music PA is controlled using L-R, and the congregation PA with delay compensation controlled using A-B.
Left, Mono, Right and Aux outputs are split between FoH, Monitor and FX duties. Monitors have inserts and long faders allowing professional monitor mixing from the FoH position.
