WZ20S User Guide 23
AUXILIARY MASTERS These provide six independent mix
outputs which can be used to provide foldback, cleanfeed and cue
monitors, effects and recording sends, zone feeds and any other
special mixes required.
AUX 1-6 Adjust the output level of each auxiliary mix. Turning the
control clockwise adjusts from fully off to +4dB boost. The normal ‘0’
position is marked.
MIX1 AND MIX2 MASTERS These are the main console
outputs. You can route each input channel to either or both outputs.
You can route MIX to create a stereo subgroup to MIX2 main output.
Both outputs provide master fader control, inserts, metering and
balanced XLR outputs. MIX2 provides additional TRS jacks and an
XLR mono output. This provides the flexibility to satisfy most audio
system applications. Refer to the section on applications later in this
User Guide.
MIX1 METERS A pair of meter bars display the post-fader left and
right output levels of stereo MIX1. Each meter has 12 LEDs to
indicate signal levels from as low as –30dB. Green and yellow LEDs
indicate normal operating levels. The top red LED lights at +16dB to
warn that you are within 5dB of clipping. Meter ‘0’ represents +4dBu
at the main outputs. The meters are peak responding. This means
that they have a fast attack and are able to display fast transients
accurately. With the output faders at their ‘0’ mark you should adjust
the mix so that the signal averages ‘0’ on the meters with highest
peaks no more than ‘+6’. This still leaves plenty of mix headroom.
MONITOR / MIX2 METERS A pair of meter bars displays the level of
the selected monitor source or PFL. With all selector switches up
these default to display the post-fader left and right output levels of
stereo MIX2.
MIX1 to MIX2 Routes the post-fader MIX1 signal to MIX2 to create a
stereo subgroup. Route all the channels you want to group to MIX1
only. Route the other channels to MIX2 only. Press the underpanel
MIX2 switch above the master fader to route MIX1 to MIX2. This is a
tamperproof switch to avoid accidental operation in situations where
MIX1 and 2 are used as independent outputs. It should be selected
using a pen or similar pointed object. MIX1 becomes a subgroup
giving you single fader control over all routed levels. You can also
insert a signal processor such as a compressor to affect all signals in
the group. MIX2 becomes the main output.
MASTER FADERS MIX1 and MIX2 each have a 100mm long throw
fader to adjust the output level. This is a stereo fader which adjusts
the left and right signals at the same time. The ‘0’ mark indicates
normal operating position. The fader can be set above or below this
depending on the output level required. A further 10dB of boost is
available at the top of its travel. However, if you find yourself normally
setting the fader in the lower half of its travel then the connected
equipment may be too sensitive for the operating level of the console.
With the fader set to its ‘0’ position adjust the input level trim of the
connected equipment accordingly.
The MIX1 and MIX2 insert points are pre-fader. The level of any
inserted processing equipment will be affected by the master faders.
The inserted equipment should be set to match the –2dBu operating
level of the console.
