phasized

@® SUBSONIC
FILTER SWITCH
The subsonic filter with the 15 Hz cutoff frequency is
actuated when this switch is depressed to the 15 Hz
(ON) position (the SUBSONIC indicator lights).
This filter serves to attenuate frequencies lower than
15 Hz with a 6 dB/oct slope and, therefore, it can be
used to suppress the ultra-low-range noise which is
generated
by record warp and other factors. This
noise cannot actually be heard by the ear but it can
cause cross modulation distortion and even speaker
damage.
Use
this switch
when
required
during
record play.
