D/A Converter Settings
A number of special settings are available for the
PDP 3000 HV
D/A converter;
they are designed to fine-tune the characteristics of your amplifier to suit your
listening preferences.
Calling up and operating
the menu
The menu is called up with a long press on the
button on the
remote control handset.
Use the
/
buttons to select a menu point.
The value can now be changed using the
/
buttons.
A second long press on the
button quits the menu.
The following set-up options are available according to what is currently being
played. For example, the SACD Oversampling settings can only be selected if
you are playing an SACD.
DSP set-up option
Oversampling (OVS)
The
PDP 3000 HV
can exploit four different filter types offering different tonal
characters:
OVS
long FIR
is a classic FIR filter with an extremely linear frequency response.
OVS
short FIR
is a FIR filter with improved peak handling.
OVS
Bezier / FIR
is a Bezier interpolator combined with a IIR filter. This process produces a
result very similar to an analogue system.
OVS
Bezier
is a pure Bezier interpolator
– offering perfect “timing” and dynamics.
Please refer to the Chapter
'Technical description - Digital filters /
Oversampling'
for an explanation of the different filter types.
Set-up option
SACD DAC Mode
All SACD discs are recorded using the DSD64 format. For this reason SACD
material is invariably played using a sampling rate of DSD64. In SACD mode,
the noise-shaping and signal processing procedures in the
PDP 3000 HV
are
optimised for the requirements of the SACD system. Depending on the
loudspeakers and amplifier system you are using, the process can be fine-
tuned in the following ways:
DAC Mode
SACD 1
High-frequency noise in the DSD signal is effectively filtered out. Universal
filter, suitable for all amplifiers and loudspeakers.
DAC Mode
SACD 2
This filter has a rather softer roll-off than the SACD1 filter. We recommend
this setting for high-bandwidth amplifiers, i.e. >= 100 kHz.
