ESOTERIC D-2 D/A Converter

In 1989, TEAC launched a D/A converter under the esoteric brand. While assuming a pair with the P-2, it is one that achieves excellent performance and functionality as a single D/A converter. In order to accommodate a variety of digital inputs, it is equipped with an auto-search mechanism to achieve a wide lock range with high accuracy.

A 45-bit 8-fold oversampling digital filter is used for the digital filter, and a newly developed noise shaper is installed to convert the calculated 45-bit gradation information into 18 bits, and the resolution below the noise level is achieved without truncating ultra-fine signals of 18 bits or less, and the linearity of the minute level is enhanced.

Equipped with a newly developed distortion shaper (ZD-II) that uses high-pass dither to achieve ultra-low distortion, it improves the signal-to-noise ratio, disperses the conversion error of the D/A converter, and further enhances the distortion shaping effect that achieves a significant reduction in distortion.
