The 4 time oversampling Z filter is carried.
While securing the phase response which was excellent with the digital filter which carries out oversampling of the sampling frequency (44.1kHz) to 176.4kHz, 4 times, and "Z filter" constituted from the 3rd Bessel filter excellent in the phase response, a passband is extended to 30kHz,The transient response property is improved.
The digital analog converter has adopted 2DAC scheme which adopts a digital analog converter for exclusive use as right and left, and has realized phase rotation zero.
The micro laser pickup is completely driven with the dynamic balance type arm.
The pickup has renewed optical system by the original replica technology and MC type focusing mechanism.
The whole compact-disk drive mechanism is carried with the perfect floating structure.
Independent equipment also of the tray lid currently united with the tray is carried out. The oscillation and the vibration are suppressed by separating an included compact-disk drive mechanism from a chassis, and float-izing a tray.
compact-disk drive mechanism "CDM-2" who adopted extensively as compact-disk drive mechanism the "high-density glass wool plastics" which is a material used for a medicine equipment etc. is developed and carried.
While investigating the thorough weight saving, the fall of resonance frequency is also realized.
The Marantz synchro REC functionality is carried.
If it combines with a cassette deck, a sound-recording start is controllable by the play switchpoint of compact-disk-45.
The remote control operation of the play of compact-disk-45 can be carried out in the combined use with remote control transmitter RMC-15, audio timer AT-333audio-video, and tuner ST-463.
If it combines with the model which carries a Marantz bus system functionality, a selector will switch to compact-disk position automatically only by pushing the play switchpoint of compact-disk-45.
Functionalities, such as a random access special NetWare program, a skip play, an index play, all-songs repeat / special-NetWare-program repeat, a three-step speed search, and a window switchover, are carried.
