DENON DCD-1000
¥ 55,000 (released in August 1985)
Commentary
A mini component size CD player that uses the W Super Linear Converter system.
It is equipped with a super linear converter originally developed by Denon.
This method reduces the D/A conversion error by adding a correction signal obtained by the conversion error detection and correction circuit in the converter to the analog signal, eliminating the 0 cross distortion peculiar to CD players.
In addition, the DCD-1000 solves the problem of the time difference between the left and right channels that occurs when the digital signal of the CD is recorded alternately on the left and right. The DCD-1000 uses a double sample-and-hold system, with a sub-sampling circuit for the left channel and alignment with the right channel.
The newly developed engineering plastic BMC (Bulk Mode Compound) containing glass fiber is used as the pickup base. In addition, the cabinet base is fully floated with a special structure containing Q-dump to cope with external vibration. The vibration of the CD itself is firmly supported by the magnet clamper.
By strongly fixing the ceiling surface, which is easily affected by external vibration, to the cabinet base, vibration resistance is dramatically improved.
The pickup unit uses a three beam system with stable tracking detection capability.
A newly developed IC with extremely fast response speed is used for the focus tracking servo circuit.
The power supply section is an independent system in which the digital system, servo system and audio system are supplied with current from independent power supply, and mutual interference between each circuit section is eliminated.
The amplifier section has a DC amplifier configuration.
Direct selection, quick selection, skip monitor, program performance of up to 9 songs, repeat performance of track program, and timer performance are available.
On the display, you can check the total recording time, track number, index number and elapsed time in the track.
The CALL key also allows you to reconfirm the program order before playing.
Equipped with deck and synchro terminals corresponding to the Denon concept series.
