'Advanced AL24 processing,' the latest technology for high sound quality
The DCD-SA1 employs Advanced AL24 processing, the ultimate analog waveform
reproduction technology developed by DENON, for use during PCM signal input
(during stereo signal processing). In addition to the data expansion of
existing AL24 Processing Plus technology, up-converted sampling is used to
achieve natural interpolation without losing original data. Greater
optimisation in digital processing algorithm has also been achieved for
ringing-free pulse response and for pulsive music data and attack sounds.
This enhances naturalness in the reproduction of spatial information such as
the delicate nuances in the music, the locations of the performers, and the
breadth, height, and depth
of the concert hall.
