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. 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
engineer’s 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. A switch option is available to
isolate these outputs using built-in relays, for example for mic live ‘on-air’
lamp switching.
The unique AB output feature provides the MixWizard with a host of
possibilities… independent 2-track recording feed, broadcast feed, studio
booth monitor, 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, sub mixing to another console, and for special
mix requirements.
SYS-LINK II OPTION A blank plate is fitted here as standard. The
Sys-Link II output option kit is available from Allen & Heath. This lets the
WZ
3 20S become a ‘slave’ console expanding the number of inputs on
another ‘master’ console using just one connecting cable. Refer to
OPTIONS later in this guide.
REMOTE (USER CONNECTIONS) A blank plate is fitted here as
standard. A 25-pin D-type connector may be fitted here and custom wired,
for example to interconnect the fader start switching option or for remote
switching of the AB output relay.
