ALPINE/LUXMAN D-102
¥ 59,800 (Released in November 1986)
Commentary
A CD player with a wireless remote control.
A 3-beam system is used for the pickup part.
In this method, the tracking error of the main beam is corrected by the sub-beam, and the servo gain is set according to the deviation of the information track. This allows the appropriate servo to work under all conditions and realizes excellent tracing.
Uses S. T. A. R. circuit for circuit design.
The D-102 is used in analog circuits such as power supply circuits and signal circuits. The SN ratio is improved by eliminating shared grounding and feeding lines and eliminating the shared impedance of each circuit.
Uses a one clock system.
In the D-102, the main clock is the clock of the D/A converter, and the microcomputer clock and the system clock are synchronized by sending the clock divided from the main clock. This prevents the beat phenomenon that occurs when multiple clocks of different systems are mounted, and suppresses sound quality degradation.
The power supply separates the digital and analog circuits, reducing the influence of high-frequency pulses transmitted from the digital circuit on the analog circuit.
It is equipped with a system remote control terminal I/O, and can be controlled by the Brid series AV surround controller separately from the included remote control.
Equipped with an 8-digit FL display.
It is equipped with functions such as 15-track random memory, 2-speed search, repeat all tracks, repeat program, and alarm clock playback.
Wireless remote control with 10 keys is included.
