FEATURES The DAS-R1 is a D/A Converter Unit to be used with the CDP-R1 CD player Unit, and forms a separate-type CD player System. The DAS-R1 converts the digital signal picked up from the Compact Disc in the CDP-R1 into an analog (audio) signal. With this separate configuration, since the vibrations and noise generated in the servo and digital circuits required for the CD player can be completely separated from the analog circuits, extremely pure quality is obtained in the resulting sound. Also, the DAS-R1 is designed to accept digital signals from a DBS (Direct Broadcasting Satellite) Tuner or a DAT (Digital Audio Tape) deck, etc. Twin linkage system to reduce phase reference Components loss The Twin Linkage system is a bi-directional linkage system between the CD player Unit and the D/A Converter Unit. In this system, a linkage to transmit the sync signal from the D/A Converter Unit to the CD player Unit is added to the conventional data transmission linkage from the CD player Unit to the D/A Converter Unit. With this system, since the crysi-j! oscillator which is provided in the CD player of conventional systems can be located near the D/A Converter section in the D/A Converter unit, the fluctuation of the phase Components output from the D/A Converter unit is eliminated from the audio signal. As a result, stable and enriched reproduction sound is obtained. Noise shaping for higher fidelity musical information In the Compact Disc format, 16-bit data is picked up from the Compact Disc 44,100 times per second. The digital filter provided with the DAS-R1 incorporates an 8 times oversampling system which improves the resolution by 8 times over normal resolution. The operation results are processed to 18-bit accuracy and then converted to 16-bit data, with no loss of high-resolution musical information, by means of noise shaping circuitry. This results in the reproduction of extremely high resolution sound. Overlap'staggered D/A conversion with extreme accuracy The overlap staggered D/A Converter is the heart of the DAS-R1 in which two D/A converters per channel operate with a shift in timing of half a period. With this system, the noise, or distortion, Components generated from both D/A converters are averaged and reduced, so that a harshless, warm tone is obtained. Standard coaxial digital inputs Two coaxial digital inputs (AUX1/AUX2), which conform to the Digital Audio Interface Format, are provided, so that the digital output signal transmitted from a DAT (Digital Audio Tape) deck or a CD player can be accepted. The DAS-R1 accommodates three types of sampling frequencies (32 kHz, 44.1 kHz and 48 kHz), and the corresponding one is automatically selected according to the input digital signals.
