Accuphase DP-80
¥ 260,000 (released in July 1986)
Commentary
As the first CD player of Accuphase, this CD transport was released as a pair with the digital processor DC-81.
The pickup section features a linear motor mechanism for fast and smooth operation, and a specially developed 8-bit microprocessor for quick music selection in less than one second.
The main body of the mechanism is mounted on a base of high-rigidity ceramic mixed special resin to prevent resonance. In addition, the mechanism is floated from the chassis to cut off the transmission of vibration. Thus, the mechanism is also floated from the disk table to minimize external vibration to the main body of the mechanism.
The timing of all operations is controlled by a single master clock so that there are no beats that would be a problem with two types of devices : digital signal processing and microprocessor.
The digital outputs include a 75-ohm coaxial cable based on the standard format and a fiber output terminal for optical transmission developed for the DC-81. The transmitter has a transmission capacity of 7Mbit/sec and can deliver high-quality digital signals to the processor. It also includes a full-fledged line filter to reduce unwanted radiation through the power supply.
The exterior uses gold-like scratch hairline finish panels and natural Persimmon sideboards.
Includes a full-featured wireless remote control.
