USER GUIDE
INTRODUCTION
The WZ14:4:2+ continues ALLEN & HEATH’s commitment to providing high quality audio mixing consoles engineered to meet the exacting requirements of today’s audio business. It brings you the latest in high performance technology and offers the reassurance of over two decades of console manufacture and customer support.
This user guide presents a quick reference to the function and application of the WZ14:4:2+. We recommend that you read this guide fully before starting. For your convenience, the manual contains information about applications, installing and connecting the console and its input and output sections. Front and rear panel drawings are included with a technical specification. A system block diagram is printed on the rear cover. For further information on the basic principles of audio system engineering, please refer to one of the specialist publications available from bookshops and audio equipment dealers.
Whilst we believe the information in this guide to be reliable we do not assume responsibility for inaccuracies. We also reserve the right to make changes in the interest of further product development.
SERVICE AND TECHNICAL SUPPORT
We are able to offer further product support through our world-wide network of approved dealers and service agents. You can also access our Web site on the internet for information on our product range, assistance with your technical queries or simply to chat about matters audio... To help us provide the most efficient service please keep a record of the console serial number, and date and place of purchase to be quoted in any communication regarding this product.
SAFETY WARNING!
Mains electricity is dangerous and can kill. Mains voltage is present within the console. Do not remove the covers with mains electricity connected. To ensure your safety, mains earth
is connected to the chassis through the power lead. Do not remove this mains earth connection.
To avoid the risk of fire, replace the mains fuse only with the correct value and type as indicated on the connector panel.
GENERAL PRECAUTIONS
Your WZ14:4:2+ is ruggedly constructed to withstand the rigours of the road whether location mixing or live gigging. However, you will extend the life of the console and preserve its cosmetics by applying these simple common sense precautions.
Prevent damage to the controls and cosmetics by avoiding drinks spillage, tobacco ash, smoke, 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.
Protect from excessive dirt, dust, heat and vibration when operating and storing.
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.
TRANSPORTING THE CONSOLE
WZ14:4:2+
The console may be transported as a free-standing unit or mounted in a rack or flightcase. Ensure that the connector pod is secured in place with the locking screws fitted to prevent movement. Use adequate packing if you need to ship the unit.
USER GUIDE 5
OVERVIEW OF THE MixWizard 14:4:2+
The WZ14:4:2+ combines uncompromised features with impressive performance for live sound engineering and recording. Built on the established tradition of innovative British design and manufacture, WZ14:4:2+ is solidly reliable for a hard life on the road and uniquely versatile for any audio mixing application. The WZ14:4:2+ is equally at home alongside top of the range live sound consoles such as the ALLEN & HEATH GL4000, in use in theatres, houses of worship, conference and club installations, home and recording studios, or multi-tasking with equipment hire companies. Check out the key features:
The Mix Wizard QCC (Quick Change Connector) system lets you quickly rotate the connectors for rear access desk top operation, or for underside access as required when mounted in a compact 10U 19” rack space.
MSP (Minimum signal path) for transparent audio is achieved by careful circuit design using high grade, low noise discrete and IC components aimed at providing the shortest signal path from input to output.
The 10 mic/line input channels each feature a 4 band EQ with 2 mid-sweep controls for source correction or enhancement equalisation, a 100Hz lo-cut filter, an EQ IN switch and individual phantom power switching on the rear panel for inputs channels, and a global on/off switch on the front panel. In addition, 6 auxiliary sends with up to 6dB of boost may be switched Pre/Post fader in groups 1-4 and 5-6. The input pre-amplifier provides a wide 70dB gain range for soft and loud signal sources. Cable matching is no longer a problem as each input offers both professional XLR and metal TRS jack sockets for any signal level, mic or line. A smooth action 100mm long travel fader with PAN control, ON switch and LED, Pre Fade Listen (PFL) switch, L-R, & groups 1-2, 3-4 routing switches and PEAK (PFL) LED indicator complete the input channel. INSERTS for effects patching and DIRECT OUTPUTS for multitrack recording are also provided on the rear panel.
The 2 full facility stereo input channels feature dual inputs, A (RCA phonos) and B (jacks) each with individual gain control and on/off switching. A 4 band EQ with HF and LF shelving together with two fixed frequency peak/dip mid controls MF1 and MF2 providing 15dB of cut or boost.
A further 4 stereo returns ST1-4 each with feeds for AUX and L-R routing bring the total number of input connections up to 26.
The Master section includes 100mm GROUP and L-R master faders each with AFL, balanced XLR connectors on all outputs and INSERTS for signal processing. The MONO output is on balanced XLR with mode switching for either LR sum (mono) output or PFL/AFL for an engineer’s listen wedge speaker. The groups also feature individual PAN controls with L-R and ON switches.
Above the groups, the AUX SEND master level controls provide an extra 10dB boost and AFL switches for monitoring. The GROUP/AUX reverse switch bank is located below the aux master section. Mode switching enables the user to reverse the aux outputs with the group outputs to configure the console for either FOH operation or on stage monitoring or both. This provides aux masters on balanced XLRs with inserts and fader control. The groups are redirected to the Aux master level controls and are on balanced TRS jacks. Individual mode switching for each Aux/Group is available permitting a wide variety of applications. Refer to the MODE SWITCHING section on page 16.
A useful oscillator allows a tone or pink noise signal to be sent to key outputs for system checking/alignment. Refer to Page 18 for details.
A headphone socket with level control is provided together with two 12 segment bargraph level meters for L & R signal monitoring.
2-Track recording and playback is set with the individual send and return level controls with routing for replay to the L-R mix. An XLR socket is provided for the talkback mic with a trim control for talkback to aux 1-2, 3-4, 5-6 in pairs.
A rugged all metal construction features all-metal jack sockets combined with individual circuit boards secured to the front panel via all rotary controls. No-nonsense solid build ensures on-the road reliability.
