Channel Jumper Options
Several link options are available to satisfy user
preferences. These require removal of the console
base panels and replugging of 2way jumpers on the
circuit boards. It is not necessary to remove
assemblies from the console. To avoid damage to
the internal assemblies this work should be carried
out by competent technical personnel.
Pre-fade Source. The source for the pre-fade aux
sends may be changed by repositioning jumper
links on each mono and stereo channel. The
default factory setting is pre-insert, pre-EQ, post-
mute. This is usually preferred when mixing
monitors from front-of-house. Select the source as
pre-insert, pre-EQ, or post-EQ by setting one
jumper. Select pre or post mute by setting another.
Set pairs of links on the stereo channels to affect
left and right signals.
Direct Output Source. The default factory setting
is post-fade. This can be changed to pre-fade.
Pre-fade follows the source as described above.
An additional option sources the output from the
AUX1 send control. This provides a post-fade
direct output with level trim. If preferred, the
channel feed to the AUX1 rotary master can be
disabled so that adjusting the direct output level
does not feed the mix. Note that this does not
affect the AUX1 send to the fader master when aux
mode is selected. Select the source as pre-fade,
post-fade, or post-fade with AUX1 trim by setting its
jumper. Set another jumper to turn the AUX1 feed
to the rotary master on or off as required.
2-TRACK Jumper Options
The 2-track output is sourced from the main LR mix.
The factory default setting is post master LR faders.
If you want to source pre-insert, pre-fader then
replug the internal jumper links on the LR MIX
circuit board as shown below. For stereo recording
from a three channel LCR mix, or by creating a new
balance from the groups, use the MATRIX outputs
instead.
