MIC / LINE IN The channel PAD (LINE) switch selects either the MIC XLR or
the LINE TRS jack as the input source. The XLR is normalled through the TRS jack.
This means that the XLR can be used for microphone or line level signals when noth-
ing is plugged into the jack socket. Both inputs are balanced but can be wired to work
with unbalanced signals when required.
WARNING: Do not connect unbalanced sources or ca-
bles to the XLR input when 48V phantom power is selected. To avoid loud
clicks always turn the channel off by pressing MUTE when switching +48V
on or off, and when plugging or unplugging cables.
STEREO LINE IN The WZ 3 14:4:2 has two stereo inputs for each of the two
stereo channels. ST1 and ST2 feed channel 11-12, ST3 and ST4 feed channel 13-14.
All inputs use TRS jacks. ST1 and 3 are unbalanced, ST2 and 4 are balanced, Unbal-
anced inputs automatically connect the TRS ring to ground for working with balanced
sources. The L input is normalled through the R input to accept mono signals.
INSERT A single 3-pole TRS jack carries the unbalanced insert signal. Tip = send,
Ring = return, Sleeve = common ground. The channel inserts are post-HPF, pre-EQ
and operate at 0dBu. The group (aux) and LR mix inserts are pre-fader and operate
at -2dBu. These should work fine with line level signal processing equipment such as
compressors, outboard EQ, delay units and so on. An example of a suitable cable is
shown here:
DIRECT OUTPUT The mic/line channel direct output is available on an imped-
ance balanced TRS jack. It is a line level signal operating at 0dBu. The source is set
using an internal option jumper for each channel. The factory default setting is pre-fade
(following the pre/post-EQ setting). This may be changed to post-fade if preferred.
The direct outputs provide a useful source for multitrack recording. Many users prefer
pre-fade sends for this application so that the live show fader movements do not affect
the recording which can be mixed later. Another application is channel effects sends.
For example, a reverb unit may be dedicated to work with the lead vocalist channel
only. Using a post-fade direct output instead of an aux send frees up that aux mix for
other purposes.
