It permits to reach the resistors to set subsonic filter cut-off frequency, the switch which activates
subsonic filter (SUBSONIC) and to insert VCA modules for the subwoofer volume remote control.
SUBSONIC FILTER ACTIVATION
Subsonic filter is activated through SUBSONIC switch under the setting panel.
• SUBSONIC switch permits to eliminate subsonic frequencies;
these sounds cannot be heard by human ears but cause useless
and damaging stress to amplifier and speakers. When it is on ON,
frequencies below the chosen cut-off one are eliminated.
Subsonic filter cut-off frequency can be adjusted through 4 Hz
steps; this occurs by replacing the special resistors located into a
socket which can be reached through the setting panel in the
amplifier bottom. The amplifier is given with 20 Hz cut-off
frequency.
