Commentary

CD player equipped with AL24Processing.

It is equipped with AL24Processing, which is an analog waveform reproduction technology inheriting the conventional ALPHA Processing technology.
In AL24Processing, the lower bit data is generated by double the arithmetic circuit of the lower bit data generation part, and by internal arithmetic processing, the lower bit 8 bit data is generated, and the upper 16 bits are added to obtain 24-bit quality output.
First, the AL24 processor receives 16-bit CD data. The rate of change extraction unit extracts the 1 LSB change portion from this data. The intelligent adaptive processing circuit generates the missing 17-24-bit data based on the extracted timing. The low-order bit is generated for each 1/256LSB change point, the high-order bit is added to the low-order bit and synthesized to obtain 24-bit quality data.
It also supports 96 kHz sampling frequency.

A multi-24-bit D/A converter is installed to faithfully D/A convert 24-bit data.
The Multi 24-bit D / A converter is not affected by variations in the power supply voltage (current), and the in-band quantization distortion level is constant regardless of frequency, enabling clear sound reproduction with less noise.
In addition, this D/A converter has a 4 dac configuration in which two D/A converters are used for each channel in differential operation, and in combination with Lambda S. L. C, which in principle eliminates 0 cross distortion, it realizes transparent sound even for very small signals.

The power supply uses a dual trans configuration that separates the audio and digital transformers to minimize interference from the digital to the audio system.
An extra-thick inlet type AC cable is also used for the power cable to reduce the impedance of the power supply.

The power transformer section uses a cast metal base with excellent vibration damping characteristics to eliminate the effect of vibration from the transformer, which is the source of vibration, on sound quality.
In addition, the use of a center mechanical mount with high structural stability, a mechanical cover that reduces the effect of vibration from the drive mechanism to the circuit, a double-structured top cover and a triple-structured bottom cover completely eliminates sound degradation caused by vibration from inside and outside.

Uses S. V. H. loader.
In addition, the loader is coated with a highly vibration-resistant protein coating, and a double-mechanical guide mechanism is used to hold both sides of the loader in metal.

Digital servo is used for the servo circuit.
The digital servo system detects and adjusts the disc condition to achieve the optimal servocontrol for each disc being played.

There are two analog outputs, fixed and variable.
It also has two digital output systems, one coaxial with the other.

OFC wire is used for the power cable.

We use carefully selected parts including ICs such as D/A converters, resistors, capacitors, and wiring materials.

Wireless remote control is included.
