Group outputs are controlled by 100mm travel faders which offer a further 10dB boost
above the normal ‘0’ dB operating level. ON switches the group output on or off.
AFL (After Fade Listen) routes the post fader signal to the console meters and
headphone monitoring to allow checks for sound quality and mix level. The AFL
signal is sourced before the ON switch allowing the signal to be checked even when
the group is switched off.
Each group has a 4 segment LED peak reading meter providing signal presence
indication and peak warning which illuminates approximately 5dB before clipping.

Sometimes it is necessary to control more than one channel simultaneously, in the
case of a drum kit or a group of backing vocalists for example. Route the relevant
channels to groups instead of L-R, using the channel group routing switches and the
pan controls. The PAN control positions the signal in the stereo image with the L-R
switch routing the group output to the Left & Right masters. Ensure the group L-R
switch is “in” to route the group output to the L-R masters. In this way, the level of
several channels can be controlled by one group fader. It is possible to set up mono
or stereo subgroups using the channel and group PAN controls.

Each aux mix has a master level control that adjusts the output level to match
external equipment, or to trim the monitor or effects level without affecting the mix
balance. Up to +10dB of boost is available above the nominal ‘0’ position.

The Mix Wizard 14:4:2 features a bank of group GROUP/AUX REVERSE (REV)
switches, one for each aux bus located under aux send masters 1-6. These switches
are recessed to avoid accidental operation. Set using a pointed object or a pen tip.
This feature allows you to set the operation of the console for Front Of House, Stage
monitor or a combination of both. With the switches out, the groups operate in the
conventional manner, channel routing being possible with the group routing switches.
When the REV switches are pressed in, the group busses are routed to the AUX
send masters and the aux busses are routed to the GROUPS (Aux 1 to Group 1,
etc). Aux 5 & 6 are routed to L-R faders respectively. This configuration allows the
user to control up to six monitor mixes with the convenience of controlling levels on
faders. Outputs are on balanced XLRs for long cable runs and a signal processor
(equaliser, compressor, limiter, etc.) can be inserted into the signal path using the
group and left/right insert jacks.
The channel L-R and group busses are still operational but are now routed to aux
master controls and can be used for additional monitor or effect sends.
It is advisable to study the Mix Wizard 14:4:2 block diagram to fully understand this
flexible routing arrangement.
An example of an application using a combined configuration could be as follows :
Route submix channels 1-6 (drum kit) to groups 1 & 2. GROUPS 1 & 2 panned left &
right respectively and routed to L-R. AUX 3-4 set prefade (PRE) and aux send
masters reversed with groups 3-4 for stage monitor sends. Other channels routed to
L-R mix as normal. Aux 5-6 set post fader (POST)for effect sends. This shows the
versatility of the Mix Wizard 14:4:2. See DUAL MODE application diagram on
page 7.
