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.
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.

through the R connection so that a mono source can be used when
nothing is plugged into the R jack socket.
EXT 1 and 2 LINE IN
EXT1 (balanced) and EXT2 (unbalanced) using TRS jacks. 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 mic/line insert
signal. Tip = send, Ring = return, Sleeve = common ground. The channel
insert is post-HPF, pre-EQ and operates at 0dBu. The LR mix insert is
pre-fader and operates 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.
This means that the XLR can be used for
