General Precautions

WIRE COLOUR

European USA/Canada

Damage : To prevent damage to the controls and cosmetics avoid placing heavy

objects on the control surface, scratching the surface with sharp objects, or rough handling and vibration.

Environment : Protect from excessive dirt, dust, heat and vibration when operating and

storing. Avoid tobacco ash, smoke, drinks spillage, and exposure to rain and moisture. If the console becomes wet, switch off and remove mains power immediately. Allow to dry out thoroughly before using again.

Cleaning : Avoid the use of chemicals, abrasives or solvents. The control panel is

best cleaned with a soft brush and dry lint-free cloth. The faders, switches and potentiometers are lubricated for life. The use of electrical lubricants on these parts is not recommended. The fader and potentiometer knobs may be removed for cleaning with a warm soapy solution. Rinse and allow to dry fully before refitting them.

Transporting : The console may be transported as a free-standing unit or mounted in a

rack or flightcase. Protect the controls from damage during transit. Use adequate packing if you need to ship the unit.

Hearing : To avoid damage to your hearing do not operate any sound system at

excessively high volume. This also applies to any close-to-ear monitoring such as headphones. Continued exposure to high volume sound can



cause frequency selective or wide range hearing loss.

Introducing the MixWizard

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

20S consoles are described in separate publications. For further information on

16:2 and WZ312:2 stereo models. The 4 group WZ314:4:2 and stereo

the MixWizard series please refer to the Allen & Heath web site.

The MixWizard is a compact console designed for professional live 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.

Both models feature a 4 band semi-parametric EQ and high pass filter per mic/line channel, 6 aux sends with combinations of pre/post switching, 100mm faders, a built-in dual effects processor with parameter control using Allen & Heath PC software, dedicated mono output with separate fader and innovative operating mode for aux fed sub systems, additional AB stereo output, comprehensive metering and engineers monitoring, dual redundant backup supply input, and a lamp socket.

The WZ stereo return inputs, a total of 20 input connections. The WZ

16:2 provides 16 mono mic/line inputs and 2

12:2 provides 10 mono mic/line inputs, 2 full

channel dual stereo inputs, and 2 stereo return inputs, a total of 22 input connections.

The base of the console can be removed to access a host of internal option jumpers. These set user preference for the aux, direct output and AB sources.

The aux 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 output card which allows the console to be linked to other Allen & Heath consoles.

Software for editing the effects parameters using a PC computer can be downloaded free from the Allen & Heath web site.

Other accessories available include the Allen & Heath MPS12 backup power supply and LEDlamp gooseneck lamp with built-in dimmer.

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:

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.

Connecting Power

EXTERNAL DC IN

RECOMMENDED ALLEN&HEATH POWER SUPPLY

REFER TO USER GUIDE FOR DET AILS

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.

WARNING: THIS APPARATUS MUST BE EARTHED

OFF

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.
