Setting items and their options
Upconversion setting
Display: UPCONV>***
o
This setting can be made for each input.
o
During Super Audio CD playback, the DSD signal is sent directly to
the D/A converter.
ORG (original)
The original input signal is sent directly to the D/A converter without
upconversion.
2Fs
32kHz, 44.1kHz and 48kHz sources are upconverted to double values
of 64 kHz, 88.2 kHz and 96 kHz, respectively, and then sent to the D/A
converter.
4Fs
32kHz, 44.1kHz, 48kHz, 88.2kHz and 96kHz sources are upconverted
to double or quadruple values of 128 kHz, 176.4 kHz or 192 kHz and
then sent to the D/A converter.
8Fs
32kHz, 44.1kHz, 48kHz, 88.2kHz, 96kHz, 176.4kHz and 192kHz sources
are upconverted to double, quadruple or octuple values of 256 kHz,
352.8 kHz or 384kHz and then sent to the D/A converter.
DSD
The signal is converted to DSD digital format, and then sent to the
D/A converter.
Note about the digital filter during PCM playback
FIR-type digital filters
This type of filter has an established reputation for sound quality
and features tonal quality with both dense, rich sound reverbera-
tions and crisp sound transients.
SDLY-type digital filters
This type of filter has no pre-echo in the impulse response and fea-
tures natural sound attack and reverberation for a tonal quality that
is close to the original.
Digital filter setting during PCM playback
Display: PCMF>***
o
This setting can be made for each input.
o
During Super Audio CD playback, this is automatically set to the
dedicated DSD filter.
OFF

o
Using this setting, high-frequency harmonic components will be
output. If noise occurs because of cross modulation from high
frequency harmonic components, for example, set “PCMF” to “FIR”
or “SDLY” instead.
