The 752BD features our unique ATF2 (Adaptive Time Filtering) upsampling technology which was developed in conjunction with Anagram Technologies, Switzerland.
All incoming audio data, such as CD quality 16-bit/4.1kHz, is upsampled to 24-bit/192kHz using a high-end 32-bit Analog Devices DSP (Digital Signal Processor) and five Wolfson audio DACs (digital to analogue convertors). "Polynomial Curve Fitting Interpolation" provides a much more accurate upsampled audio soundwave than traditional upsampling processes. And a unique timing system buffers audio data to almost eradicate digital jitter. Vital – as jitter, common in digital audio devices, loses vital detail, often leaving digital audio sounding flat and lifeless.
