D/A converter with distortion shaper ZD-II

Description
A D/A converter released by TEAC in 1989 under the Esoteric brand.This unit is designed to be paired with the P-2, but also offers excellent performance and functionality as a stand-alone D/A converter.It is equipped with an auto-search mechanism to support various digital inputs, and achieves a wide lock range with high accuracy.

The digital filter is a 45-bit 8x oversampling digital filter,In addition, a newly developed noise shaper is installed to convert the accurately calculated 45-bit grayscale information to 18 bits,Even ultra-fine signals of 18 bits or less are not discarded, and the resolution below the noise level is realized, enhancing the linearity of the minute level.

Newly developed distortion shaper (ZD-II) with high-pass dither for ultra-low distortion ratio improves S/N ratio and disperses D/A converter conversion errors, further enhancing the distortion shaping effect for significantly lower distortion ratio.
Spec
Condition Excellent working order. Cosmetical condition is 7/10.
