■ Equipped with analog waveform reproduction technology AL24 Processing in the playback system
AL24 Processing , an analog waveform reproduction technology that reduces quantization distortion and supports high-bit and high-sampling of next-generation media . It is equipped with this high-quality digital technology . AL24 Processing greatly improves the calculation processing accuracy and reproduces the input 16-bit digital data with 24-bit quality. This enhances the ability to play music at low levels, such as when the music disappears quietly or when it starts with silence .
■ Equipped with high-precision multi-24bit D / A converter
A multi-bit 24-bit D / A converter is used to faithfully perform D / A conversion of 24-bit high-quality data obtained by AL24 Processing . The multi-24bit D / A converter is not easily in-band quantization distortion level is constant regardless of frequency, enabling clear sound reproduction with little noise. increase. Furthermore, in principle, it reproduces minute signals realistically in combination with ΛS.LC, which eliminates zero-cross distortion. It even expresses the subtle nuances of transparent
■ We adopt high-performance ATRAC-IC
The heart of the sound quality of MD recorders, ATRAC, is equipped with a high-precision ATRAC-IC that can input and output 24-bit data. Combined with the block floating arithmetic processing, which has significantly increased processing power compared to the past , rich expressive power and minute level signal reproduction are realized .
■ High-quality recording with a 24-bit A / D converter
The A / D converter is equipped with an enhanced dual-bit ΔΣ 24-bit A / D converter to achieve high-precision recording. As a result , while reproducing a rich sound field with excellent sound image localization and depth, the linearity is secured at a minute level and the high S / N is acquired .
