DENON DCD-1800R
¥ 159,000 (released in January 1985)
Commentary
A CD player developed with the best of DENON's technology.
The D/A converter is equipped with a super linear converter developed by DENON.
In this circuit, the correction signal from the conversion error detection correction circuit is added to the signal converted and output by the selected high-precision and high-stability D/A converter to reduce the conversion error, completely eliminating the 0 cross distortion.
Uses a high-precision 11th order analog filter composed of carefully selected parts to eliminate harmonic components peculiar after D/A conversion.
A linear drive tracer, which is a mechanism for broadcasting business equipment, is adopted for the pickup mechanism part, and high-precision and high-stability tracing capability is obtained.
The amplifier section uses a DC amplifier with a servo circuit using high-precision parts.
Large transformers and condensers are used for the power supply.
In addition, the three independent power supply configuration eliminates interference between sections, and the conversion of digital circuits to ICs greatly reduces current consumption and reduces complicated wiring to improve the S / N ratio of audio circuits.
Equipped with a centralized display that allows you to check track number, index number, minutes and seconds, track number of the next song, etc.
It is equipped with functions such as direct selection, program performance of up to 15 songs, index search, intro search, skip monitor, program call, repeat all songs / program songs / between A and B, and quick selection.
Equipped with timer playback function, can be used in combination with an optional timer.
Equipped with a headphone port with volume.
Equipped with side wood.
There was a wireless remote control sold separately.
