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 2-
track recorder in studio mixing. In mono mode, the M output can provide an addition-
al feed for a mono fill speaker or zone, or be used as the main feed into a mono PA.
Used with a mono PA the L and R mix can provide a pair of subgroups, each with rout-
ing using the channel PAN controls, inserts and faders. Configured to provide the
AUX6 mix, the M output is ideal for driving a sub bass speaker system when working
with an 'aux fed subs' PA. This provides the sub feed with its own per-channel mix on
balanced XLR and with dedicated fader alongside the main LR faders for proper control
of the house volume.
AB OUT A pair of impedance balanced TRS jacks can be configured to provide an
additional LR mix or engineers monitor send. These operate at -2dBu line level. A
front panel recessed 'mode' switch determines the source to the AB output. This may
be set to follow the console monitor system and therefore feed an independent local
stereo monitor or even engineers wedge speaker. When set to follow the LR mix, the
factory default source is taken post LR fader. An internal option jumper is available to
change this to pre LR fader.
The unique AB output feature provides the MixWizard with a host of possibilities...
independent 2-track recording feed, broadcast feed, zone and delay fill feeds, local
monitor, engineers wedge monitor and more.
AUX OUT 1-6 Each aux send is available on an impedance balanced TRS jack oper-
ating at -2dBu line level. An internal option is available to fit a balanced line driver IC
to provide an electronically balanced output operating at +4dBu. Note that it is not
usual to require this option as the impedance balanced standard drive provides signifi-
cant interference rejection when feeding balanced equipment inputs.
The aux sends are typically used to feed stage monitors, effects devices such as reverb
and delay, and for special mix requirements.
FOOTSWITCH Mutes and unmutes the ST5 (ST1) effects return channel, ideal for
Footswitch
bypassing the effects between songs. Note that this affects the internal processor and
also any external effects device that may be plugged in to these return inputs. Use a
momentary or latching footswitch as required. Shorting a TS or TRS jack tip to sleeve
turns the mute on.
USB II OPTION A blank plate is fitted here as standard. The USB II option kit is
available from Allen & Heath. Refer to OPTIONS later in this guide.
