WELCOME TO THE ALLEN & HEATH The WZ16:2 continues ALLEN & HEATH's commitment to provide 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 userguide presents a quick reference to the function and application of the WZ16:2.
OVERVIEW OF THE The WZ16:2 offers the professional user an uncompromised feature set and performance for live sound engineering and recording. Built on the established tradition of innovative British design and manufacture you get a console that is both solidly reliable fora hard life on the road, and uniquely versatile to adapt to any audio mixing application.
Here are a few typical WZ16:2 applications. For clarity, the input sources, signal processing such as EQ, and the amplifiers are not shown: PA with Live Recording - Typical of the up-andcoming band playing the small venue. Simultaneous stereo and multitrack recording for the demo tapes. Extended Speaker System - Typical in a theatre with a wide stage, and a disco/club. Here, the A-B outputs feed a centre fill speaker and a sub-bass for extended low frequency performance.
INSTALLING THE CONSOLE The MixWizard Series features the ALLEN & HEATH Quick Change Connector (QCC) system. The rear connector pod may be hinged and locked into either of two positions: Rear connectors for desktop operation with the control panel sloped at a convenient 15 degrees, or Underside connectors for 19" rack mounting in a compact 10U space. The connector position can be easily changed at any time to fit your application.
CONNECTING MAINS POWER Refer to the SAFETY WARNING on page 3 of this User Guide. Check that the voltage indicated on the rear panel is the same as the mains supply in your area. Check that the correct mains lead with moulded plug has been supplied with your console. Read and understand the warnings and instructions printed on the rear panel and shown here. It is standard practice to turn connected power amplifiers down or off before switching the console on or off.

PLUGGING UP THE CHANNELS The MixWizard Series uses professional grade 3-pin XLR and 1/4" TRS jack sockets. We recommend that you use suitable quality cable and connectors and check your leads for reliable soldering and continuity before use. It is well known that most audio system failures are due to faulty interconnecting leads.
PLUGGING UP THE OUTPUTS L-R MIX INSERTS L-R MAIN OUTPUTS Use these sockets if you wish to insert external signal processing equipment into the LR mix post-mix amp and pre-L-R fader. This lets you check the effect of the inserted equipment using the console headphones or local monitor. For live sound it is common to insert graphic equalisers to adjust for the room acoustics. In recording you could plug in a compressor to prevent unexpected peaks overloading the recording.
INPUT CHANNEL PAD - Attenuates the input signal by 30dB. Affects both the XLR and jack inputs. Press this switch when the input signal is too high even with the GAIN control backed off. GAIN - Use this control with the PAD switch to adjust the channel input sensitivity to match the connected source (-60 to +10dBu) to the console operating level (0dBu). Use the PFL function to check that the signal reads an average '0' on the meters.
STEREO RETURNS Two stereo return inputs ST1 and ST2 are provided giving you a total of 20 inputs to the L-R mix. These may be used for returning the processed signal from the effects devices, monitoring and replaying your 2-track recording, expander or submix inputs, or for stereo intermission replay. AUX1 LEV - Sends the return signal (L and R combined into mono) to the Aux1 mix independent of the level to the main mix. This lets you feed effects to the performers monitor.
OPTIONS The MixWizard Series WZ16:2 has a versatile architecture designed to satisfy most live sound or recording applications you may encounterwithout modification. However, the following internal options are offered to provide alternative settings for those applications that may demand them. These options require resoldering of circuit board links and should only be carried out by competent technical personnel. Further information is available from your service agent or the WZ16:2 SERVICE MANUAL.
A- B O U T P U T The A-B output is an additional stereo/mono output that can be uniquely configured as either a separately controllable mix output, or a local loudspeaker monitor feed. MODE SWITCH - This switch is recessed under the panel to prevent accidental operation. It is operated using a pen tip or similar pointed object. In the normal up position A-B follows the main L-R mix. When pressed A-B follows the monitor switchbank + PFL to become a 'local' monitor in addition to the headphones.
