A Portable MD player with "Mobile 1-bit digital amplifier"
"
The 1-bit digital signal is sent to a constant voltage circuit directly from a high-order ∆Σ modulation circuit.
The amplifier transmits and amplifies the signal, and
allows extremely natural and clear sound with little
deterioration.
"
High-quality sound is achieved by vast improvements
in the sound resolution. The speed and the smoothness of rise of the sound are consequently ensured.
!
122-hour* playback and 57-hour* recording
"
The low power consumption LSI, consisting of the
ATRAC LSI and the high-order ∆Σ modulation circuit,
enables extended hours of playback.
(* Refer to "Specifications" on page 66.)
