Aux pre/post EQ For convenience, this option
is a recessed front panel switch per channel. No
internal access is required. The up position is post-
EQ, pressed is pre-insert and pre-EQ. Note that this
setting affects all pre-fade sends from the channel,
including auxes and direct output.
Direct output source Factory default is pre-
fader. This is common for live recording to
multitrack. The live mix fader movements do not
affect the recording. Move the jumper from PR to
PO to change to post-fade. Post-fade is appropriate
when using the output as a direct channel effects
send.
Channel Aux pre/post settings Factory
default is Aux 1-4 = switched, Aux 5-8 = switched,
Aux 9-10 = switched pre/post fader. You can
change the setting of Aux 1-2 from switched to
permanently pre-fade or post-fade if preferred.
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.
Return Aux pre/post settings The stereo
returns feed Auxes 1, 2 and 9-10. Factory default is
the post-fader so that the fader becomes a master
for all feeds from the return. This may be changed
to pre-fade if you prefer. Move the two jumpers from
G to F.
Talkback mic +48V Factory default is +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 OFF 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.
