FR-2 Field Memory Recorder (Chapter 5: Recording/playback)
The FR-2 is equipped with the high-pass filter circuit. The cutoff frequency is 100
Hz and the filter slope is -12 dB/oct. The [HPF] switch, which selects ON or OFF of
the high-pass filter, is provided for each channel.
The filter is useful to eliminate the wind noise during location recording or unnec-
essary low frequency noise when recording a voice or sound.
