Press the FILTER button on the front panel or D.FILTER
button on the remote control unit to select a digital filter
type FLAT or PULSE.
Click noise may happen from speakers
or headphones when changing the digital
filter. It is recommended to change the
filter after volume down.
Note: Digital filter type is always FLAT when DSD
signal is played, and PULSE is not available.
Note: When the display is "off " by dimmer setting
pressing once the FILTER button will return the
display brightness to the default "brighter " and
show the current digital filter type. Press the
button again to change the digital filter type.
FLAT digital Filter is very common in digital audio items.
The frequency response is almost perfect, but such filter
cause "ringing " in the time domain. Some energy of a
pulse signal is distributed in the time domain, before and
after the pulse centre. Any ringing before the signal does
not exist in nature.
PULSE digital filter avoids the problems in the time
domain and thus has a very good response in the time
domain. The frequency response of the PULSE digital
filter shows a soft roll-off at high frequencies. This results
in about -2dB at 20kHz with an input sampling frequency
of 44.1kHz. For higher sampling frequencies the roll-off is
irrelevant and the " PULSE " filter is the best choice. For
44.1kHz and 48kHz the better result may depend on the
whole system as well as personal preferences.
