The compact disk player which adopted 2DAC and
18-bit conversion system.
Newly developed 2DAC and 18-bit conversion
system are adopted as a D-A-conversion part.
In this circuitry, the digital
analog converter is carried in each Lch/Rch, and an 18-bit high resolution has
been obtained by controlling the data sent to each digital analog converter by
18-bit processor LSI. The reappearance capacity of a minute signal is conjointly
improved sharply with the high resolution by an 18-bit 4 time oversampling
The classAA scheme original with the output buffer
amplifier of an audio circuitry is adopted, and the stable waveform transmission
which does not receive the ill effect of a connected load is realized.
Moreover, digital one / analog separation power circuit is adopted as a
power circuit, and the ill effect to the analog circuit is protected from the
In order to stop the ill effect by the oscillation from
the outside, the BMC mechanism base which has the thermal resistance of 200
degrees C and the outstanding periodic-damping property in an optical deck part
is adopted. The high vibration proof effect is acquired by carrying out the
floating of this deck.
In moreover, the actuator of the traversal mechanism
to which a pickup is movedThe high speed linear-access system by a linear motor
is adopted, and while the original control system which made full use of a
microcomputer realizes a rapid access, a high endurance and silence are acquired.
The edit guide functionality is carried, the number of music, the sequence
of music, and sound-recording time which can be recorded on a tapes A side
/ B side only by choosing the enrolment time (90 minutes, 60 minutes, 46
minutes) of the tapes to record can be calculated automatically, and it
can display on a display device.
Moreover, it is also possible to program music, specifying
sound-recording time arbitrarily and checking the residual time of a tapes.
After carrying the auto peek search and carrying out the autmatic
detection of the peak level of disk all songs or special-NetWare-program music,
peak-point order }3 seconds can be repeated and performed. The optimal recording
level by the side of the deck can be easily set up by utilizing this
The large-sized function-logic-diagram multi-display
which can display a music matrix display device, 4 mode time, etc. is carried.
The coaxial digital output termination is carried.
Functionalities which reproduce only the intro fractions of a repeat /
A-B repeat, a random play, and music for 15 seconds at a time, such as a music
scan, 2 speed manual search, a skip, and an index search, are carried.
If the power-on timer is carried and the disk is contained at the time
of the power source ON, a play will be started automatically.
headphone jack which carries a variable volume is carried.
27 key full
remote control is attached.
