Grace Design will debut its 2-channel A/D converter option ($995) for the m201 preamp system at this week's 123rd AES Convention in New York City's Javits Center (booth #739). Designed to be seamlessly integrated into an m201 preamp, the new 24-bit/192kHz capable A/D converter is recommended for music production, post-production, broadcast and live performance applications.
The A/D option comprises a hardware module that's installed internally in an m201 chassis; its connectors are available through a rear panel slot. Operating controls and metering are supplied on a front panel assembly. Customers can order m201 preamps from the factory with the A/D option installed, or upgrade existing units.
The low-latency A/D converter operates at sample rates from 44.1 to 192 kHz at 24 bits. Four output connectors are available at the rear panel of the m201 and include two AES3 outputs on female XLRs, an AES3-id/S/PDIF output on BNC and a Toslink optical output. All outputs are active simultaneously. Professional and consumer formats are supported, as are single and dual wire AES3. In addition, two +4dBu line-level inputs are provided as XLR male connectors.
The A/D can be sourced from both of the m201's mic preamp channels, the M/S matrix L-R outputs and the line inputs. The latter allows the user to use the A/D as a high-definition, stand-alone A/D converter. External sync is available via BNC connectors for word clock and Digidesign LoopSync. The converter employs Grace Design's s-Lock dual stage PLL for stable, low-jitter audio performance.
Grace Design expects to ship production versions by mid-November. For more information, visit http://www.gracedesign.com/.
