TransAudio Group has announced the availability of the Drawmer A2D2, an AES Grade 1 dual stereo output analog-to-digital converter. The stereo A/D converter offers dual simultaneous stereo outputs, each with separately selectable sample rates, and additionally provides three word clock outputs, allowing the A2D2 to also act as a master clock generator.

For maximum flexibility, the stereo A/D converter in the A2D2 provides simultaneous dual stereo outputs that may each be selected to different sample rates, including 44.1, 48, 88.2, 96, 176 and 192kHz. This permits, for example, the output of a high-resolution 192kHz version with a simultaneous lower resolution 44.1kHz version. Each digital output has a selectable word length of 16 or 24 bits, with automatic dither generation.

Level control of the dual Burr Brown analog input stages is via fully variable front panel rotary controls, operating over the range of -2dBu to +28dBu, or 24-turn precision presets for a fully calibrated input. Accurate 24-segment peak reading LED bar meters display incoming signal levels from -50dBfs to 0dBfs and also include separate overload LED indicators.

The A2D2 incorporates an AES Grade 1 standard low jitter clock generator and offers three word clock outputs to allow the unit to act as master clock generator. An external clock input allows the user to select an alternative clock source without having to re-route clock cables. The A2D2 uses a linear power supply to minimize interference with the internal clocks.

Noted Brad Lunde, president of TransAudio Group, the US distributor for Drawmer "A good sounding A to D converter that delivers two different digital outputs at different sample rates is unique. I don't know of another converter that delivers a 96 or 192 main output and a 44.1 copy at the same time."

US MAP price: $1,975.00
