Commentary
A CD player with a real 20 bit super linear converter.
The D/A converter is equipped with a real 20-bit S. L. C (super linear converter).
Unlike dynamic bit shift converters that use attenuators and switching circuits, this Real 20-bit converter has no nonlinear distortion factor, and the 0 cross distortion, which is a problem at low volume, is caused by the resistance error of the MSB, the most influential bit in D/A conversion. Therefore, the distortion is eliminated by correcting this MSB.
In addition, a 2D/A system with independent left and right channels has been adopted to eliminate the L/R time difference.
The digital filter uses an 8 x oversampling digital filter. By increasing the sampling frequency by 8 x, the band gap between the music signal and the noise signal is widened, making it easier to remove noise components.
This allows the use of lower-order analog filters to improve sound quality.
The analog circuits are L/R-independent configuration along the signal flow to eliminate mutual interference between channels.
The power supply circuit consists of five independent power supplies. One digital section, one pickup servo system, one display system, and two audio systems are supplied separately to prevent sound quality degradation due to mutual noise and voltage fluctuations.
A linear motor pickup is used for the pickup mechanism to enable high-precision tracing.
The pickup mechanical base is made of BMC (Bulk Molding Compound), which has high rigidity and excellent vibration damping characteristics. In addition, this mechanical base is made into a double floating structure with low-repulsion rubber and spring to increase the vibration absorption effect.
The chassis structure is a bi-breath, double chassis. The unique double chassis structure with inner and outer chassis prevents external vibration, increases rigidity and eliminates resonance. In addition, the bottom surface is covered with another reinforcing rigid metal from the outside of the external chassis to increase vibration isolation.
In addition, vibration from the top surface is suppressed by adopting large auxiliary rigidity metal for the top plate and inserting anti-vibration material between the top cover and the top cover.
It uses a remote control electric volume that can also be used as headphones.
Two digital output systems are mounted : optical and coaxial.
It is equipped with a new time search function, and it is possible to start the music by time designation and repeat performance between 2 points.
Equipped with auto-edit and auto-space functions.
Random play and program play up to 20 songs are available.
Compatible with 8 cm single CD.
Wireless remote control is included.
