3.1.8 OptiSample® (RCD-777 only)

The CD-77 Compact Disk Processor offers 6 user-selectable methods of Sampling that can be cycled through during playback by pressing the OptiSample® button (RC10) on the RCD-777. The sampling options are:

a. Digital Master I – this mode directly takes the data extracted from the CD and re-clocked to generate the music signal. Due to the complete lack of digital or analogue filtering, the treble frequencies are slightly rolled off, making the sound somewhat soft and laid-back. For the same reason, the mid- range and below is very natural and realistic. The reproduction of impulses is undistorted. This mode often helps to tame overly-bright recordings.

b. Digital Master II (default) – this mode is identical to Digital Master I but complements this with a special analogue filter which corrects the roll-off in the treble frequencies. As a result, the tonality is more accurate in the treble. We therefore recommend this mode as the benchmark with which to enjoy music.

c. Oversampling 2x – this mode engages the Digital Filter with an oversampling factor of 2, thus performing the least digital processing possible (except for no digital processing). The original data from the CD is in effect discarded and re-placed with a re-computed version. This new version of the music is mainly linearly scaled up using a whole number as scaling factor and resolution/edge enhanced.
