16 WZ 3 20S User Guide
AUX SENDS These rotary controls adjust how much channel
signal is mixed to the aux outputs. Each of the 6 auxes has its own
control. They adjusts from fully off to +6dB boost. Unity gain 0dB is
marked at 3 o’clock position. Auxes 1-4, 5-6 are switched pre/post.
These settings may be changed if preferred by repositioning internal
jumper link options. They offer many different combinations of pre and
post-fade sends, and a post-EQ option for the pre-fade sends. More
detail is provided in OPTIONS later in this guide.
Pre-fade aux sends are not affected by the channel fader movements.
These are typically used to feed stage monitors. In most cases users
also prefer that the monitor sends are not affected by inserted
processors or the channel EQ. Post-fade aux sends follow the channel
faders and are typically used to send a proportion of the channel signal
to an effects device such as reverb or delay. Note that post-fade
sends may be preferred when the console is configured in monitor
mode so that the faders become ‘masters’ for all monitor mixes. Pre or
post-fade sends may also be used for special applications such as
recording, zone feeds, clean feeds and aux fed subs.
PRE When pressed, the pre-fade channel signal is sent to the
associated auxes. When released, the post-fade signal is sent. Auxes
1 to 4 and 5, 6 are grouped for pre/post switching. You can change
this by repositioning the internal option jumpers.
PAN Positions the channel signal between L and R in the stereo
mix. The centre position (mono image) is detented for quick resetting.
MUTE When pressed the channel signal is turned off. This affects
the feed to the LR mix, pre and post-fade aux sends and direct output,
but does not affect the insert send. The red indicator lights when the
channel is muted.
PFL Press PFL to listen to the pre-fade channel signal in the
headphones or AB monitor (if configured) without affecting the main
outputs. The console main LR meters are interrupted with the channel
signal. The red PK indicator half lights to show that PFL has been
selected on that channel. Selecting more than one PFL at the same
time mixes those signals together in the monitor.
PEAK The red indicator illuminates when the channel pre-fade
signal is within 5dB of clipping. This gives you enough warning to
reduce the GAIN control before you hear signal distortion.
SIGNAL The green signal presence indicator lights when the
channel pre-fade signal is greater than -12dBu.
FADER Controls the channel level feeding the main LR mix and
post-fade aux sends. It also affects the direct output if this has been
set to post-fade using the internal option jumpers. The fader provides
+10dB maximum boost above its normal unity gain 0dB position.
A switched fader option is available. This replaces the standard
channel fader with a high quality dual rail Alps K-fader with fitted micro-
switch for on-air lamp or equipment start switching. See OPTIONS.
Important note on setting channel levels: Use PFL to set the GAIN
controls for correct signal level through each channel. Use the faders
to balance each signal in the mix. These are typically operated around
their -20 to 0 positions according to the mix. We do not recommend
setting the faders to ‘0’ and mixing using the GAIN controls.
