Boulder, CO (November 8, 2007)–Grace Design has launched its 2-channel, A/D converter option for the m201 preamp system. Designed to be integrated into an m201 preamp, the new 24-bit/192 kHz-capable A/D converter is targeted for audio professionals in music production, audio post, broadcast and live performance applications.
Physically, the A/D option consists of a hardware module that’s installed internally in an m201 chassis and whose connectors are brought out to a rear-panel slot. Additionally, the operating controls and metering for the A/D are supplied on a front-panel assembly. The m201 preamps can be ordered from the factory with the A/D option installed or can be upgraded on existing units.
The low-latency A/D converter operates at sample rates from 44.1 to 192 kHz at a bit depth of 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 +4 dBu 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 MS matrix L-R outputs and the line inputs. The latter allows the user to utilize the A/D as a high-definition, standalone A/D converter solution. External sync is available via BNC’s for Word Clock and Digidesign LoopSync. The converter employs Grace Design’s s-Lock dual-stage PLL for stable, ultra-low jitter audio performance.
The front panel includes dual 20-segment LED peak reading meters that display true digital peak values over a 60 dB range. Two input sensitivities are user-selectable from the panel, and each can be calibrated individually.
