ESOTERIC D-2 D/A Converter

This D/A converter was released by TEAC under the ESOTERIC brand in 1989, and while it was designed to be paired with the P-2, it also offers excellent performance and functionality as a standalone D/A converter. The D/A converter is equipped with an auto search mechanism to accommodate various digital inputs, and achieves a wide locking range with high accuracy.

A 45-bit 8x oversampling digital filter is used for the digital filter, and a newly developed noise shaper is used to convert the accurately calculated 45-bit gradation information to 18 bits, so that even ultra-fine signals of 18 bits or less are not truncated and the resolution below the noise level is achieved. The resolution below the noise level is achieved without truncation of ultra-fine signals below 18 bits, and the linearity of fine levels is enhanced.

The newly developed distortion shaper (ZD-II) with high-pass dither for ultra-low distortion improves the signal-to-noise ratio and disperses the conversion error of the D/A converter, further enhancing the distortion shaping effect for a significantly lower distortion rate.
