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.

WZ14:4:2+

10 Mic/Line Inputs

◆

High gain, low distortion preamps

match all signals, from -60dBu.

distance miking to +10dBu high level electronic instruments.

◆

Individually selected +48V.

Phantom Power on all mic/line inputs.

◆

Jack inserts on each input provide

easy access for gates, compressors etc.

◆

100Hz low-cut filters.

◆

Exceptional 4 band EQ with 2 mid sweeps, with overlapping frequency for complete corrective and creative access to all frequencies. EQ bypass switches enable easy in/out comparisons and eliminate noise on untreated signals.

◆

Peak and PFL warning LED.

◆

6 aux sends on individual controls. Auxes 1-4 and 5-6 can be set pre or post fade for monitor feeds or fx processing. Aux levels provide up to 6dB boost when needed. Sends are taken post EQ, post on switch, though internal links can enable changes to the default settings if required.

◆

Channel ON switch with LED.

◆

Pan controls with centre detent allow panning across groups and LR

◆

100mm smooth throw faders for precision control and up to +10dB extra boost.

◆

Direct outs are provided post-fade for multitrack recording and special feeds.

2 Stereo Inputs

◆

Independent A and B sources on phono and 1/4” jack connectors respectively.

◆

4 band EQ.

◆

Routing to all 6 auxes, with internal links allowing selected auxes to be configured as stereos.

◆

Outputs to busses, with the stereo image positioned via a balance control.

◆

Peak and PFL led and switch.

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.
