The MP 3100 HV can exploit four different filter types offering different tonal
characters:
OVS long FIR (1)
is a classic FIR filter with an extremely linear frequency response.
OVS short FIR (2)
is a FIR filter with improved peak handling.
OVS Bezier / FIR (3)
is a Bezier interpolator combined with a IIR filter. This process produces a
result very similar to an analogue system.
OVS Bezier (4)
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.
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.
Please refer to the Chapter 'Technical description - Digital filters /
Oversampling ' for an explanation of the different filter types.
