High-pass Filter

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.
