Introducing the MixWizard The Allen & Heath MixWizard series of consoles includes several models. This user guide describes the WZ416:2 and WZ412:2 stereo models. For further information on the MixWizard series please refer to the Allen & Heath web site.
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: 19” Rack Mount For rack mounting, remove the two side trims and rotate the pod into the connector position preferred. Allow enough space for the cables and connectors behind the console.

Audio Connections The MixWizard uses professional grade 3 pin XLR and 1/4" TRS (3 pole) jack sockets. To ensure best performance, we recommend that you use high quality audio cables and connectors, and take time to check for reliable and accurate cable assembly. It is well known that most audio system problems are due to faulty or sub standard interconnecting leads.

The Console connectors MIC / LINE IN The channel PAD (LINE) switch selects either the MIC XLR or the LINE TRS jack as the input source. The XLR is normalled through the TRS jack. This means that the XLR can be used for microphone or line level signals when nothing is plugged into the jack socket. Both inputs are balanced but can be wired to work with unbalanced signals when required.
L, R, M OUT The main console mix outputs are on balanced XLR. These produce +4dBu when the meters read ‘0’. The M output can be switched to provide a mono sum of the post-fade L and R signals, or the AUX6 output. The L and R outputs typically feed the house PA system in live sound mixing, or a 2track recorder in studio mixing. In mono mode, the M output can provide an additional feed for a mono fill speaker or zone, or be used as the main feed into a mono PA.
The MONO Input Channel +48V PAD (LINE) 30 +48V Switches +48VDC to the channel input XLR for powering microphones or DI boxes that need phantom power. The power is current limited through 6k8 ohm resistors to pins 2 and 3. 40 0 20 GAIN 50 - 10 10 60 40 HPF HF WARNING: Do not connect unbalanced sources or cables to inputs with phantom power selected. To avoid loud clicks always mute the channel before switching +48V on or off and when plugging or unplugging microphones.
+48V PAD (LINE) 30 AUX SENDS These rotary controls adjust how much channel signal is mixed to the aux outputs. Each of the 6 auxes has its own control. They adjust from fully off to +6dB boost. Unity gain 0dB is marked at 3 o’clock position.
The STEREO Input Channel 0 -5 GAIN 5 -10 10 -20 16 ON TO TO 9-10 Dual stereo inputs Each of the two stereo channels has two stereo inputs which can be used separately, mixed together or split so that one feeds the channel, the other routes direct to LR. For example, you could mix two sound effects playback devices or two reverb returns together into one channel. This can be useful in saving channels, letting you mix many inputs in a small space.
The STEREO Effects Channel The MixWizard WZ416:2 and WZ412:2 feature a built-in stereo digital effects processor. The processed signal is routed back to the mix through the ST1 (ST5) stereo return channel. The two stereo effects mix together into the return channel. The ST1 (ST5) TRS jack inputs mix with the internal effects processor through the return channel. This allows you to have the internal and external effects devices returning their processed signals through one return channel.
The Master Section AUX MASTERS Each aux mix has a master level control that adjusts the output level to match external equipment, or to trim the monitor, effect or other send without affecting the mix balance. Up to +4dB boost is available above the normal 0dB position. PRE Note that the AUX5 and AUX6 master controls do not affect the level sent to the internal effects processor. They do affect the level available at the rear panel aux output sockets.
ST2 (ST6) RETURN This is a simple stereo return channel that routes to the main LR mix. The typical application is to plug in a CD or similar playback device for walk-in or background music. It can also be used as an additional effects return. Adjust the volume using the LEV control. Route the signal to LR by pressing the TO LR switch. The green LED lights to warn that the source is routed to LR. You can use the ST2 (ST6) input to monitor your 2-track recording.
Gain Structure How the levels between the different signal stages are set up is referred to as the gain structure. For best performance it is important that the connected source signals are matched to the ‘normal operating level’ of the console. Similarly the levels of the connected amplifiers and destination equipment should be correctly matched to the console outputs.

User Options REMOVE 4x M4 POZI SCREWS PER SIDE REMOVE SIDE TRIMS The MixWizard has a versatile architecture which should satisfy most applications you may encounter without modification. However, the following internal options provide alternative settings for those applications that may demand them. Access is required to the internal assemblies. pluggable jumper links are used in most places and also some links require cutting and soldering a solder bridge.

This is common for live recording to multitrack. The live mix fader movements do not affect the recording. Move the jumper from PR to PO to change to post-fade.
AUX master balance option The 6 aux outputs are impedance balanced as standard operating at nominal -2dBu and with +21dBu maximum drive. They provide similar interference rejection to electronically balanced outputs when connected to balanced equipment inputs. An electronically balanced option is available if you require nominal +4dBu and higher output drive up to +26dBu over very long cable runs.
