The subsonic filter is a High-pass filter with a
very low frequency cut-off for the subwoofer
output. With this function used, overdriving the
subwoofer and subwoofer amp can be reduced.
Inaudible, low frequency energy below 15 or 30
Hz (selectable) can be reduced using this
feature.
Notes:
• Setting the switch to the "OFF" position
leaves your subwoofer open to possibly
damaging subsonic frequencies.
• This switch is provided on the rear panel.
