Method High-speed linear access system. Dimensions Width 430 x Height 116 x Depth 333mm. CD player employing a newly developed 4-DAC, 18-bit conversion system. The D/A conversion section employs a 4DAC, 18-bit conversion system. This circuit employs 4 D/A converters, 2 each for Lch and Rch, and the D/A converters dedicated to the positive and negative signal sides of both channels are fully coupled by the newly developed 4DAC processor LSI, thereby eliminating zero-cross distortion in principle and achieving 18-bit high-resolution operation. The result is a high resolution operation of 18 bits, which significantly improves the ability to reproduce minute signals. This greatly improves the ability to reproduce minute signals.In addition, a 266-order high-precision 18-bit quadruple oversampling digital filter is used to remove unwanted high-frequency components, and by resolving the signal level from the conventional 16 bits to 18 bits, higher fidelity reproduction is possible. The line-out and headphone circuits employ classAA, a unique high sound quality circuit technology.
This ensures faithful waveform transmission even with complex connection loads, resulting in an ultra-low distortion rate and high resolution. A high-speed linear access system using linear motors is employed in the drive unit of the traverse mechanism that moves the pickups. High-speed access is achieved by refining a unique control system that makes full use of microcomputers, which improves operability and at the same time achieves high durability and quietness. In addition, the pickups are equipped with integrally molded glass lenses for superior signal readability and high reliability. A multi-layered base and a multi-layered top panel made of different types of metals are used to reduce vibrations that adversely affect sound quality. Floor vibration directly transmitted from the installation stand is reduced by adopting a multiple insulator configuration with four large insulators and a double floating optical deck. Two digital outputs, optical and coaxial, are provided. A digital output ON/OFF switch is provided to block the influence of the digital output during analog playback. The power supply circuit uses independent two-wire power transformers for the audio and digital servo systems to prevent the audio system from being affected by the fluctuating digital and servo circuits. In addition, a low-noise active servo power supply provides a stable power supply.An edit guide function is provided to automatically calculate and display the number of tracks, track numbers, and recording time that can be recorded on tape side A and side B simply by selecting the recording time (90 minutes/60 minutes/46 minutes) on the tape. Digital peak search is provided to automatically detect the peak level of the entire disc or programmed songs, and then repeat the peak level for ±3 seconds before and after the peak point, for a total of 6 seconds. This function makes it easy to set the optimum recording level on the deck side.
A wireless remote control is included. International Buyers - Please Note. Thank you for your understanding.
