Grace Design a802 A/D Converter Option for m802 (AES/EBU Out with Word Clock)

Includes 2 sets of 8 channel AES3 outputs on DB25, Word Clock in and Out, and 1 set of AES3-id outputs on 4 BNC connectors.The m802 A/D converter card option provides m802 users with state of the art A/D conversion for the most demanding music recording applications. The purpose for this new card is to provide A/D conversion technology capable of matching the transparent, musical character of Grace's mic preamplifiers, with the combination of the two creating a new level of true audio purity.

The A/D converter employs a fifth order delta-sigma modulator and a low pass filter that exhibits very wide dynamic range and low latency. With a more gentle slope digital filter than other A/D chips, it is the most musical of the high end converter ICs. It is capable of 120dB dynamic range with distortion and noise artifacts at less than -110dB. Separate power supplies for the analog and digital portions of the A/D converter ensures that the precision delta sigma modulator will not be affected by other surrounding circuitry. As well, the differential inputs provide additional input noise rejection.
