Digital Filter - Teac Esoteric DV-50 Owner's Manual

DVD VCD CD MP3
This switch changes the digital filter for the 2 channel high quality
analog audio output terminal.
RDOT:
This is a digital filter using Fluency theory. The RDOT filter has
a slow roll-off and natural extended audio characteristics and
provides frequency multiplication.
FIR:
This FIR-type digital filter also provides frequency
multiplication. It has a sharp roll-off and firmly-defined bass
characteristics.
RDOT+FIR:
This combines the RDOT and FIR filters, allowing the best
characteristics of each filter to be used.
< During playback of a SACD, the DSD filter is selected
automatically, and the DSD indicator lights instead of the UP
CONVERT indicators.
