YAMAHA CDX-890

Commentary

CD player using PRO-BIT system.

Equipped with Yamaha's original PRO-BIT (Precise Reproduction of Original Bit) system.
PRO-BIT converts 16-bit data read from a CD into 20-bit data by calculating the correction value for quantization error based on the time series change of the data. Specifically, approximately 20000 patterns of Yamaha's 20-bit recorded data and 16-bit data obtained by truncating the lower four bits of the data are stored in an LSI and compared with 16-bit data read from a CD to calculate the correction value for 20-bit data. This greatly reduces the conversion error at the minute level.

The D/A converter is equipped with Yamaha's original I-PDM DAC.
In this method, each waveform pulse is handled independently, and even if the output pulse waveform is not ideal, distortion does not occur in principle, and high-purity analog signals can be obtained.

Uses LiD power supply with excellent low-impedance capability.

The servo circuit uses an intelligent digital servo to trace in an optimal state according to the state of the disk set in the tray.

The influence of vibration is reduced by a brass mechanical base, a highly rigid chassis with double bottom, and a disk tray with Exaine material.

Equipped with two digital output terminals that are coaxial with the optical system.
In addition, variable and fixed lineout output terminals are mounted.

It is equipped with tape program, autospace function and synchronous REC function.

It is equipped with 3 stage dimmer control which can change the brightness of the display.

Wireless remote control is included.
