D/A Converter Settings
A number of special settings are available for the
MP 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
D/A converter options
Briefly press the

 

button on the remote control handset in order to call
up the D/A converter set-up options. This action opens a set-up window in
which the various options are displayed.
•
Now use the

DSP set-up option
Oversampling (OVS)
The
MP 3000 HV
can exploit four different filter types offering different tonal
characters:
•
Oversampling
1
(long FIR) is a classic FIR filter with an extremely linear
frequency response.
•
Oversampling
2
(short FIR) is a FIR filter with improved peak handling.
•
Oversampling
3
(Bezier / FIR) is a Bezier interpolator combined with a IIR
filter. This process produces a result very similar to an analogue system.
•
Oversampling
4
(Bezier) is a pure Bezier interpolator – offering perfect
“timing” and dynamics.

DSP set-up option
Output phase
With particular instruments or voices the human ear is certainly capable of
detecting whether absolute phase is correct or not. However, absolute phase is
not always correctly recorded.
In this menu item the phase of the signal can be changed from normal to
inverse phase and back.

The correction is carried out at the digital level, and has absolutely no adverse
effect on sound quality.
DSP set-up option
Bandwidth (BW)
In this menu item, the bandwidth of the analogue output filter can be switched
between 60 kHz (normal mode) or 120 kHz (
'
WIDE
'
mode).
The ‘WIDE
’
setting allows a more spacious music reproduction.
