According to the analog audio signal fed to the [ANALOG IN] connector, set the LINE-MIC
switch to "LINE" or "MIC". When you select "MIC", set the phantom power switch to "48V",
"DM" or "T12" appropriately according to the microphone connected.

The PD204 is equipped with the high-pass filter circuit. The cutoff frequency can be adjusted
within the range between 50 Hz and 300 Hz, while the filter slope can be selected between
-6 dB/oct. and -12 dB/oct.
The filter is useful to eliminate the wind noise during location recording or unnecessary low
frequency noise when recording voice or sound. You can make filter setting for each channel
individually.

By using the limiter when recording microphone sound, the signal level is prevented from
exceeding a certain level. In result, the signal level fluctuation is suppressed. By default, the
threshold of the PD204 limiter is set to -12 dB under the 24-bit full-scale level (all bits are
ON) and the compressed ratio is set to 1:5. The limiter attack time is fixed to 5 ms, while the
release time is fixed to 200 ms. You can set limiter parameters using the "Limiter parameter"
menu item in the "SYS SETUP" menu of the MENU mode (see page 156 for details).
