GROUPassignment section
The XR-20 offers a flexible group assignment arrangement. Each of the four
Groups can be assigned to Left, Right and Mono busses, 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 OUTjacks 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 but-
tons are down.
GroupPK / SIG LED indicators
These two-color(green & red) LEDs are used to monitor
each of the group’s signal levels. Signal present (green) is monitored pre-fader. Peak
(red ) is monitored at the preamp and both before & after the fader.
AFL buttons for Groups 1, 2, 3 & 4
Each of the four groups has an AFLbutton 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 - left, even -
right. The Peak (red) LEDs are illuminated to show AFLstatus.
