The Console Connectors
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 nothing 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 cables 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, Unbalanced 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 impedance 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.
