D-5/D-50
FEATURES
Extremely compact size for easy transport
By
connecting
the
optional
Sony
EBP-9LC
battery
case,
this
CD
jacket-sized player can be operated on batteries, which enables you
to enjoy the sound of Compact Discs anywhere you want.
High performance and fidelity
Flat frequency response (20--20,000 Hz), low wow and flutter (lower
than the measurable limit), wide dynamic range (more than 90 dB),
minimal
distortion
(less
than
0.008%)
and
high
channel
separation
(more
than
85
dB)
are
achieved.
Listening
to
the
sound
reproduction
is
just
like
being in the concert hall.
Full-logic “feather touch” operation
At the lightest touch, the "feather-touch” function keys enable you
to switch directly from one mode to another.
AMS and SEARCH function
The AMS (Automatic. Music Sensor) function for locating the
beginning of a selection on the disc and the SEARCH function for
locating the desired point in a particular selection.
Digital readout display
The track number and the playing time elapsed of the selection
playing is shown on the LCD(Liquid Crystal Display) window. With
one touch of the REMAIN button, this time display will change to in-
dicate with a minus sign how many selections and how much
playing time are left on the disc.
Non-contact signal readout system
Because a laser beam is employed for signal pick-up, there is no
physical contact with the disc, which means no wear.
In addition, because the pit pattern is recorded below the surface of
the disc, it is not necessary to be constantly on guard against dust,
making the disc easy to handle.
