Controls / Indicator
1 EXPANDER switch
When this switch is turned ON the dynamic
range is increased.
2 LPF (Low-Pass Filter)
FREQUENCY control
This control adjusts the frequency band
output from this unit.
3 INFRASONIC switch
Ultralow frequencies that cannot be
reproduced even by a subwoofer speaker
do not become sound but become
unnecessary oscillations, which affect the
sound by causing distortion, etc. Setting
this switch to "15 Hz" or "25 Hz" cuts the
frequencies below the respective
frequency.
This improves the reproduction
performance of the speakers by eliminating
unnecessary oscillations which will not
become sound.
