Marantz CD880J 90,000yen(around the 1988 time)

The compact disk player developed by the basis of the theme of playing a music more faithfully.

The 4 time oversampling digital filter and 2DAC scheme of a 16-bit are adopted.
Furthermore, paying attention to improving the basic performance of the LSI itself, TDA1541A and system-application-architecture7220 P/B are named "A version", and are carried.

compact-disk drive mechanism who was carried in LHH1000 and realized Ryo Oshige and quantity rigidity by a die-casting frame in the mechanism,CDM-1MK2 developed based on CDM-1 making full use of the know-how of the ultralight pickup accumulated through the old mechanism development and silence-izing is adopted.
The swing arm scheme of one beam is adopted as a pickup, a weight saving is carried out as much as possible to the whole mechanism's weight hardened by die-casting, and play ability is conjointly raised with the precise servo system.

The original ARC (Alminum Raft Ceiling) structure is adopted.
With the aluminum top cover of 2 piece structures which omitted the shape of Raft (raft), while increasing an intensity, the oscillation mode was diffused and the vibration is prevented.
Moreover, aluminum die-casting is adopted as a chassis and the vibration and the oscillation are further reduced combining a large-sized insulator and sub- wood panel.

In order to prevent the cross interferencee of a digital circuit and an analog circuit, it becomes independent about a digital circuit, an audio circuitry, a servo circuitry, a display-device circuitry, etc., respectively, and is considered as the substrate layout which banished the wraparound of the noise.

The large-sized power transformer excellent in the Europe regulation was carried in the power-source part, and the mass electrolytic capacitor for audios of 6,800 micro Fx2 is adopted.
Moreover, the digital circuit and the analog circuit were made into the coil according to full independence, and the wraparound of the noise generated from a digital circuit is prevented.

The digital output of optical 2 systems is carried as the coaxial (75-ohm coaxial).
Moreover, analog output carries the variable output which is interlocked with a master volume in addition to a fixed output.

compact-disk filing bank FTS (Favorite Track Selection) is carried.
If memory is once disappeared and carried out with the filing system of compact disk which chooses and memorizes a favorite track even if it turns OFF a power source, it is filed eternally.
