Introducing the MixWizard WZ4 14:4:2 The Allen & Heath MixWizard series of consoles includes several models. This user guide describes the WZ414:4:2 4 group model. The 2 bus WZ412:2 and WZ416:2 consoles are described in separate publications. For further information on the MixWizard series please refer to the Allen & Heath web site. The MixWizard is a compact console designed for professional sound mixing.
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 INPUT 1 2 +IN MIC - IN 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.
GROUP (Aux), 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 PFL/AFL engineer’s wedge output. The L and R outputs typically feed the house PA system in live sound mixing, or a 2-track recorder in studio mixing. In FOH 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 +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. (LINE) 0 20 30 40 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.

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. Auxes 1-4, 5-6 are switched pre/post.
The STEREO Input Channel Dual stereo inputs GAIN 0 -5 5 -10 10 -20 OO 16 ON TO TO 11-12 GAIN LR (ST1+ST2) -5 0 5 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 GROUP/AUX Masters AUX MASTERS Each aux mix has a master level control that adjusts the output level to match external equipment, or trims the monitor, effect or other send without affecting the mix balance. Up to +10dB boost is available above the normal 0dB position. AUX AFL Press AFL to listen to the post-level aux mix in the head- AUX 1 +10 OO AFL REV GRP1 TO LR PAN L R PK! +6 0 SIG 1 MUTE AFL phones and local monitor without affecting the main outputs.
The Master Section Console Monitor Comprehensive engineer’s headphones and local monitoring is provided. MIC IN TALKBACK TRIM PHONES MIN Select either LR or 2-track return as the default source using the L-R / 2TRK switch. Pressing PFL or AFL elsewhere on the console automatically overrides the current monitor source with the signal from the channel or mix selection. The red PFL/AFL active indicator illuminates and the console meters display the active signal.
TALKBACK, SIGNAL GENERATOR and MATRIX TALKBACK Individually assignable talkback is available to all the main outputs. Plug in a suitable cable or gooseneck microphone. A good quality dynamic or condenser vocal microphone is recommended. Note that +48V phantom power is available at the XLR as standard. If you prefer, this can be disabled by repositioning an internal jumper link.

User Options 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.
Aux pre/post insert / EQ Factory default for the mono channel pre-fade auxes is pre-insert, pre-EQ. This is popular with many users mixing monitors from FOH. It prevents the channel EQ and inserted compressors affecting the monitor mix. Move the jumper from A to B to change this to post-insert, post-EQ if preferred. Note that auxes are always post-mute. MONO CH - AUX PRE/POST EQ PR PO PR PO DIR AUX Direct output source Factory default is pre-fader. This is common for live recording to multitrack.
Output balance options The aux and matrix 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.
