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.
