Setting the digital filter
used by the D/A converter
Display: DF>*****
This setting can be made for each input separately.
During SACD playback or during conversion to DSD format, this is
automatically set to the dedicated DSD filter.
OFF
With this setting, no digital filter is used in the D/A converter.
Using this setting, high frequency harmonic components will be
output. If noise occurs because of mixed modulation from high-
frequency harmonic components, for example, set "DF" to "FIR"
or "S_DLY" instead.
FIR1
The cutoff frequency of the FIR-type filter varies according to the
input sampling frequency.
FIR2
Regardless of the input sampling frequency, a FIR-type filter with a
cutoff frequency of about 80 kHz is used.
S_DLY1
The cutoff frequency of the S_DLY-type filter varies according to
the input sampling frequency.
S_DLY2
Regardless of the input sampling frequency, a DLY-type filter with a
cutoff frequency of about 80 kHz is used.
About the D/A converter digital filters
FIR-type digital filters
This type of filter has an established reputation for sound
quality and features tonal quality with both dense, rich sound
reverberations and crisp sound transients.
S_DLY-type digital filters
This type of filter has no pre-echo in the impulse response and
features natural sound attack and reduces reverberation for a
tonal quality that is close to the original.
Word input settings during CD/SACD playback
Display: WORD>***
Word synchronization does not function when external input
mode is used.
OFF
Word synchronization is not used.
ON
Word synchronization is used.
The word synchronization frequencies that can be input are 44.1
kHz, 88.2 kHz, 176.4 kHz and 10 MHz.
When using 10 MHz input, more time is required to lock
compared to other frequencies.
Setting analog output attenuation
Display: ATT>***
When set to ON, you can adjust the attenuation value using the
VOLUME buttons.
When set to OFF, the VOLUME and MUTING buttons are disabled.
When using this unit together with an ESOTERIC amplifier, set this
to OFF.
OFF
The VOLUME buttons cannot be used to control the volume.
ON
The VOLUME buttons can be used to control the volume between
0 and −99 dB.
