GROUP Assignment Section
The X 18R and X 20R offer a flexible group assignment arrangement. Each of the four
Groups can be directly assigned to Left, Right and Mono buses, in any combination.
M - Mono assignments for Groups 1, 2, 3 & 4
Each of the four groups has a Mono assignment button for routing its
post-fader signal to the Mono mix bus.
L - Left Assignments For Groups 1, 2, 3 & 4
Each of the four groups has a Left assignment button for routing its
post-fader signal to the Left mix bus.
R - Right Assignments For Groups 1, 2, 3 & 4
Each of the four groups has a Right assignment button for routing its
post-fader signal to the Right mix bus.
Group Master Faders 1, 2, 3 & 4
Each Group has a master fader for adjusting its overall level. These signals show up at the
Group OUT jacks on the rear panel and can be assigned to the Left, Right and Mono buses.
They also feed the Solo system when the Group AFL buttons are down.
GroupPK / SIG LED Indicators
These two-color LEDs are used to monitor each of the group’s signal
levels. Signal present (green) is monitored pre-fader. Peak (red) is moni-
tored at the preamp and both before & after the fader.
AFL Buttons For Groups 1, 2, 3 & 4
Each of the four groups has an AFL button for monitoring through the
SOLO system. The signal assigned to the Solo bus is picked up after the fader. The groups
show up in stereo in the Solo system - odd to left, even to right. The Peak (red) LEDs are
illuminated to show AFL status.
