D/A Converter Settings
A number of special settings are available for the MP 2500 R D/A converter;
they are designed to fine-tune the characteristics of your amplifier to suit your
listening preferences.
The following settings can only be called up if PCM-encoded audio is
being played.
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 / buttons to select a set-up option.
In each case the displayed option can be altered using the /
buttons.
Press the button again to leave the menu.
The MP 2500 R can exploit four different filter types offering different tonal
characters:
Oversampling FIR long is a classic FIR filter with an extremely linear
frequency response.
Oversampling FIR short is a FIR filter with improved peak handling.
Oversampling Bezier / FIR is a Bezier interpolator combined with a IIR filter.
This process produces a result very similar to an analogue system.
Oversampling 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.
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.
