ROLLOFF Setup Screen
The ROLLOFF setup screen controls
the low frequency audio response of
the IFBT4 by moving the 3 dB corner
of a 4 pole lowpass digital filter. The
50 Hz setting is the default, and should be used
whenever wind noise, HVAC rumble, traffic noise or
other low frequency sounds may degrade the quality of
the audio. The 35 Hz setting may be used in the
absence of adverse conditions, for a fuller bass
response.
Press MENU to return to the Setup window.
