NOTE:
When the RG-9's power switch is set to the OFF position and
the processor switch is also set fo OFF, the signal which has
bypassed the processor circuitry is nnde available at the

SELEcToR
This selector selectsmaximum gain boost value with
respectto the input level, i.e.: ratio of gain increase
between large input signal
and small ipput signal.
Max-
imum gain boost increases
as the selector is turned
clockwise.Set the selector
to the most desirable
position
while listening
to the reproduced
sound.
* DynamicExpansion
Dynamic expansion is defined as the sum of the downward
expansion (wheresmall inputs are expandeddown) and upward
expnsion (wherelargeinputs are expanded
up).
