The pit information read from the disk is turned into a digital signal by the signal processing LSI and sent to the digital filter and D/A converter, but during this time the digital signal generates jitter, which causes the digital signal to fluctuate little by little on the time axis. The original information contained in digital signals is a coded numerical sequence that is not affected by the transmission system, but when transmitted as an electrical signal, it is a sequence of pulse signals. For this reason, the digital signal that has passed through many circuits fluctuates irregularly, with the pulse width being longer or shorter than originally intended, resulting in the clock having jitter and the signal time during D/A conversion. This will deteriorate the axis accuracy.In the digital sink IC, the digital signal once generated by the signal processing LSI is re-timed to the precision of the master clock just before the D/A converter. This is a system in which the master clock, which determines the time axis accuracy of the signal, is directly connected to the D/A converter. By adjusting the timing to the precision of the clean master clock that does not include jitter, the digital signal is reorganized, and the D/A converter is outputting. Since the effects of jitter do not extend beyond the D/A converter, phase-accurate and faithful D/A conversion is possible.The digital filter is equipped with CXD-1244, an 8fs45bit noise-shaping digital filter. In addition, the CXD-1244 achieves in-band ripple characteristics of within ±0.00001dB and an echo level of -124dB or less through its 45-bit high-order processing capability.The CXD-1244 performs extremely high-precision calculations with a calculation bit length of 45 bits. However, since D/A converters can only have a finite number of bits, rounding errors occur and remain as quantization noise. To solve this problem, we have adopted a high-resolution D/A converter with excellent characteristics and introduced a noise-shaping method, which is incorporated into the CXD-1244. Noise shaping incorporates lower-bit information, which would normally be lost due to rounding errors, into upper data by taking advantage of the time interval caused by oversampling.Equipped with digital de-emphasis function. With digital de-emphasis, the de-emphasis processing that was conventionally performed in the analog circuit section is performed by digital processing inside the digital filter, eliminating sound quality deterioration caused by parts and circuits and obtaining ideal gain and phase characteristics. Masu.The D/A converter IC is equipped with a high-precision linear D/A converter. This is a high-speed operation type that supports the data output speed of an 8fs digital filter, enabling more advanced D/A conversion. This improves linearity for minute-level signals. In addition, this D/A converter is a single-chip IC with highly stable conversion operation, and linear operation is achieved from the most significant bit to the least significant bit. Not true. This eliminates the need for additional circuits such as gain switching, simplifying the analog circuit section. Furthermore, a dual configuration with independent left and right channels eliminates phase shifts between channels.The servo circuit is equipped with S Servo III. The S Servo III removes harmful noise components through a low-pass filter and sends a smooth servo current to the servo circuit to reduce the impact on the audio circuit. Furthermore, unnecessary vibrations of the optical system mechanism are suppressed.Remote control includedWEB No.2010410000121808[Display based on the Secondhand Goods Business Law: Shizuoka Prefecture Public Safety Commission No. 491160001440] ?Note only for products that are turned on.?????????????Products that do not turn on are not eligible?
