S-Stage Dynamic Expansion Selector
'The expansion in the dynamic range can be switehed in
3dB steps from 4B to 16¢B with this Setting selector. By
combining the upward and downward expansion, it is
possible to produce the optimum expansion in the dynamic
range and also to select the expansion according to the

Faithful Reproduction Funct
The sensor section which produces the control signal is
Provided with an energy cistibuticn filter, to ersure that
Preserves Natural Impression
'Atiack and release characteristics of the audio signal are
preserved by a fast and slow response (mixed) double ac:
ton control signal that prevents unnatural impressions in
the reproduced sound.
Fluroscan is incorporated for the meter which indicates
the degree of the dynamic range's expansion. This
new kind
of display accurately tracks the processing action and it
allows readout of the expansion

Smart, Slimly Designed Styling
The processor has been slimly designed with the dynam
ic expansion moter, which employs a Fluroscan display, in
the center for a clean, fresh look. The height dimension of
the front panel conforms to the F1A* standard 2U size
format. Using the optional rack mount adaptors (JA-R1O4),
the processor can be installed in a rack confarming
to ELA,
the expansion function is not rigged by noise components,
However, expansion is not limited to instruments, whose
fundamental frequency is close to the center frequency of
the energy distribution filter, since all musical instruments
