Drawmer introduces A2D2 dual-output A/D converter
May 9, 2008
UK-based Drawmer has introduced the 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 provides three word clock outputs, allowing the it to also act as a master clock generator. The TransAudio Group distributes Drawmer in the United States.
The stereo A/D converter in the A2D2 can select independently among 44.1kHz, 48kHz, 88.2kHz, 96kHz, 176kHz and 192kHz sample rates for its two stereo outputs. 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. A linear power supply minimizes interference with the internal clocks. In addition, an external clock input allows the user to select an alternative clock source without having to reroute clock cables. For more information, visit
