The compact disk player which carries a variegated
performance time edit function.
The auto edit function is carried, and
the special NetWare program of the span which does not exceed the time specified
first is created automatically, and is performed in an order from the music of
the beginning of a disk, or the specified music. Moreover, a special NetWare
program is made freely, checking residual time in the span of the specified time
by a manual edit function.
The auto fadeout functionality by a fadeout
key is carried.
The blank time for a minimum of 4 seconds can be automatically set up between the music and music to perform.
According to the residual time of a tapes, the "music display function
within residual time" which indicates the numbering of the music which
can be performed to within a time by blinking is carried.
In order to eliminate a digital noise, the digital
circuit and the analog circuit are connected by the optical-transmission scheme.
The optical-transmission scheme has adopted the L/R serial data, the latch
pulse signal, the clock signal, the control signal, etc. as six lines.
The 16-bit oversampling digital filter is adopted and the burden of an
analog filter is eased by extending the space character of a music signal and a
sampling noise.
In order to prevent the digital noise mixed in an analog
part via a power circuit, it dissociated from the coil of the power transformer
and the interference digital one / between analogs is eliminated.
The
digital output termination is carried.
In order to release an optical
pickup system from the influence of an oscillation, the vibration-proof design
optical chassis is adopted, and the original floating suspension of NEC is
absorbing the extraneous vibration and the internal oscillation by rotation of a
motor.
Three kinds of repeat functions, an index search, an intro scan,
24 music random program memory, 2 speed music search, and the skip song
selection functionality are carried.
The headphone jack with a volume is
carried.
The power-on start functionality which can be performed at a
timer start is carried.
Two analog output terminals, variable and a
fixture, are carried.
Wireless remote control with a ten key is
attached.
