NOTE:
When the RG-9's power switch is set to the OFF position and
the processor switch is also set to OFF, the signal which has
bypassed the processor
circuitry is made available at the
OUTPUT jacks. There will, however, be no output if the input
level control is set to the'0'position. Make sure that this control
is set to the'10'position.

* Dynamic Expansion
Dynamic expansion is defined as the sum of the downward
expansion (where small inputs are expanded down) and upward
expansion (where large inputs are expanded up). For deails, refer
to "Technical Outline" on page 7.
