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 additional 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 routing 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.
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 operating 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 significant 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.
MIDI IN
A standard 5-pin DIN MIDI input socket is provided. This is
used with external MIDI equipment or a MIDI equipped PC to control the
built-in effects processor mute, presets and parameters. Free software
can be downloaded from the Allen & Heath web site for PC editing of the
parameters via MIDI.
FOOTSWITCH
Mutes and unmutes the ST5 (ST1) effects return
channel, ideal for 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.

Sys-Link II option kit is available from Allen & Heath. Refer to OPTIONS
