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 INPUT +IN 1 2 MIC - IN 3 TIP +IN RING -IN LINE 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 a master console or house PA system in live sound mixing, or a 2-track recorder in studio mixing. In mono mode, the M output can provide an additional feed for a mono recording, fill speaker or zone, or be used as a mono sub mix feed into a master console or PA.
The MONO Input Channel +48V PAD (LINE) 30 0 20 +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 GAIN 50 - 10 10 60 40 HPF HF -15 3k +15 4k 1k 700 HM 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 adjusts 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 0 -5 GAIN 5 -10 A 10 -20 16 ON TO LR TO CHANNEL 0 -5 GAIN 5 -10 B 10 -20 Dual stereo inputs Each of the eight 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 EXT1 and EXT2 Inputs The WZ320S provides two additional stereo inputs for signals such as effects returns, sub mix sources, sound effects and CD players. EXT1 features a fader and independent sends to auxes 1 to 4. EXT2 is a simple input that routes direct to the LR mix through the TO LR switch. AUX 1 +6 AUX 2 +6 AUX 3 +6 AUX 4 EXT1 AUX SENDS The signal can be routed to Auxes 1 to 4. These sends are not affected by the EXT1 fader which returns the signal to the LR mix.
The Master Section AUX 1 AUX 1 +4 STEREO 1-2 AUX 2 AUX 2 +4 AUX 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.
PHONES EXT2 LEV 0 TO LR L R With the mode switch in its up position, the LR mix is selected as the source to the AB output TRS jacks. Factory default setting is post-LR fader. If preferred you can change this to pre-LR fader by repositioning internal option jumpers so that the LR master fader movements do not affect the output. In LR mode the AB output provides an additional main mix output ideal for independent fill speaker control, 2-track recording, broadcast feed, booth monitor and so on.
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.
WZ320S Application Notes The WZ320S is well suited to many high performance live, recording and installed sound applications including multi source stereo mixing, multi output sub mixing, club systems, small broadcast, production mixing… and more. The following notes present suggestions for these applications. Of course, you may find different or better ways to suit the particular requirements of your application.
Multi Output Submixing The WZ320S is built to the same high standard as top end consoles used in major live sound applications. Its all steel construction, together with individual circuit cards, make it ideal as a professional sidecar to the FOH console. It provides a versatile 4 mono, 8 dual stereo format for sub mixing a wide variety of sources. Typical applications include on-stage stereo keyboard mixing, and sub mixing effects returns to the main FOH console.

User Options – Channel Cards 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. For user convenience, pluggable jumper links are used in most places.

They provide similar interference rejection to electronically balanced outputs when connected to balanced equipment inputs.
User Options – AB Output Relay Switching The AB output routes to its TRS connectors through a relay which is normally switched on. A remote switch may be wired to solder pads on the connector circuit card to switch the relay off and isolate the output. One application is in a broadcast studio where a booth monitor should be muted when its local mic is live. In this case the relay would be wired to a micro-switch on the mic channel fader.
