Aux pre/post EQ
Factory default for the mono
channel pre-fade auxes is pre-insert, pre-EQ. This is
popular with many users mixing monitors from FOH.
It
prevents
the
channel
compressors affecting the monitor mix. Move the
jumper from A to B to change this to post-insert,
post-EQ if preferred, for example when using
corrective EQ affecting FOH and monitors. Note that
auxes are always post-mute.
Direct output source
fader (as set for the pre-fade auxes).
common for live recording to multitrack. The live mix
fader movements do not affect the recording. Move
the jumper from C to D to change to post-fade.
Post-fade is appropriate when using the output as a
direct channel effects send.
Channel Aux pre/post settings
default is Aux 1-4 = switched, Aux 5-6 = switched
pre/post fader.
You can change these settings for
different combinations of permanent or switched
pre/post fade auxes by repositioning the links. Note
that these are solder links on the mono channels.
Refer to the system block diagram to explore the
possibilities. Make sure you set all mono and stereo
channels the same.
To avoid possible future
confusion when the console is used by other
operators, we recommend you only change these
settings if absolutely necessary.
Stereo/Mono aux source
channels feed the auxes with a mono sum of L+R.
This can be changed so that L feeds the odd
numbered auxes, and R the even.
preferred when using odd/even auxes as stereo
pairs. Factory default is the mono setting.
Talkback mic +48V
phantom power turned on for the front panel
talkback mic XLR input. The option jumper is behind
the TB mic XLR on the L Master board. If you prefer,
phantom power can be disabled by repositioning the
jumper to the GND position.
Note that phantom power should not harm non-
powered dynamic microphones as long as balanced
connections are used.
WARNING:
Do not connect unbalanced
sources or cables to inputs with phantom power
selected. To avoid loud clicks do not press the
TALK switch when plugging or unplugging the
talkback microphone.
