YAMAHA CDX-800

Commentary

This is a CD player that uses 8 times over sampling and 18 bit high bit system just like the high-end model.

The digital filter is equipped with an 8 fsx 18-bit digital filter. The digital filter has 225 + 41 + 21 orders of operation order and achieves 8 times oversampling by high-precision digital operation.
By raising the sampling frequency of CD from 44.1 kHz to 352.8 kHz, which is eight times higher than that of CD, this digital filter shifts sampling noise, which adversely affects audio signals, to a higher frequency range. Furthermore, the digital filter itself has characteristics of -100dB or less for out-of-band noise and ± 0.0001 dB or less for in-band ripple. Both digital filters have achieved high performance of 16 bit resolution or less. This reduces the occurrence of pre-echo and post-echo, which affect sound quality.

The D/A converter uses an 18-bit left / right independent twin D/A converter.
In order to eliminate quantization errors, this D/A converter receives the 18-bit output of a digital filter and performs D/A conversion with a resolution four times higher than that of conventional D/A converters. This realizes more faithful D/A conversion the minute signal level where the number of bits decreases.

Equipped with a high-bit direct switch, pure DAC direct output without passing a low-pass filter is possible.

The pickup unit has a built-in head amplifier to improve S/N ratio when reading signals.
In addition, the servo circuit is equipped with a 2-way computer servo, which automatically switches between fast response and slow response, reducing disturbance in digital signal processing and improving tracing capability.

It is equipped with a tape-edit function that allows you to dub your favorite songs in the desired order according to the length of the cassette tape.

Equipped with coaxial digital output.

0.4 dB step digital volume is mounted.
This volume has a dynamic range of 120 dB by 20-bit operation.

Equipped with a headphone port linked to digital volume.

Equipped with 2 speed monitor search, it is possible to fast forward and fast backward while playing. With this function, it is slow at first, and if you keep pressing it, it becomes fast.

Equipped with an index search.

One touch direct music selection is possible with 10 keys on the main unit or 24 keys on the remote control.

Equipped with 3-mode program functions of manual, delete and auto (random).

Equipped with 4-mode repeat function between 1 song / all songs / program / A and B.

It can be used with an external timer to play back an alarm clock. Since it is equipped with program backup, you can play your favorite songs.

Equipped with 24 songs music calendar.

Equipped with an 8-digit FL display with volume level display.

There are 2 color variations of titanium and black.
It also comes with a full 46-key remote control for each color.
