Sum Switch
The Sum switch causes Control Room Inputs to
be additive instead of mutually exclusive
(X-OR). When active, the Sum switch tempo-
rarily bypasses any Trim values currently ap-
plied to any of the inputs.
The Sum switch latches on, allowing you to se-
lect the inputs to be summed. The Sum switch
lights to indicate that it is active.
Submixer Output
When the To Monitor switch in the Line Sub-
mixer controls is engaged, the stereo output
from the Submixer is routed internally and au-
tomatically summed with the Left and Right
channels of the current Control Room Input se-
lection, and are excluded from the C, Ls, Rs, and
LFE channels. Any Trim values applied to the
current input are also applied to the summed
Submixer output.
