6-13-2 Configure audio LPF (low pass filter)

The audio low pass filter is useful to cut off high tones (allowing low tones to pass) to

improve intelligibility of weak signals in close proximity to adjacent interference and to

remove hiss making listening for extended periods easier on the ears.

There are four available pass frequencies:

3KHz, 4KHz, 6KHz and 12KHz.

The lower the frequency the more limited the audio bandwidth. For highest fidelity for

listening, select 12.0KHz. The filter selection can be set to automode to select the proper

filter setting automatically.

The default is AUTO.

To access the configuration menu, push the FUNC key and then push the 7 key.
