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
