Grace Design Introduces A/D Option for m802 Preamp

Grace Design will debut its 8-channel A/D converter option ($1,695) for the m802 remote controllable preamp system at the AES show in San Francisco this week, October 6, 7 and 8 at the Moscone Convention Center. The new 24-bit/192kHz capable A/D converter option is designed to be seamlessly integrated into a Grace Design m802 preamp system.

The A/D converter consists of a hardware module that’s installed internally in an m802 chassis; its connectors are accessible the m802’s rear panel. It will be offered in two versions.

The first version includes a DB-25 connector that provides two parallel 8-channel sets of AES3 format outputs in single-wire mode or eight channels in dual-wire mode. Four BNC connectors accommodate AES3-id and S/PDIF formats, providing a total of eight channels in single-wire mode or four in dual-wire. A word clock input and word clock/loop sync output are provided on BNC connectors.

The second version instead offers two optical connectors that allow two parallel 8-channel sets in ADAT format or eight channels of SMUX at 96 kHz. An A/D converter can be divided into three basic functional blocks: the analog input stage, the A/D converter and clock generation (or regeneration).

Grace Design expects to ship production units by mid-October. The company will be located at booth #1505 at this week’s AES show.
