The A2D2 A/D converter from Drawmer boasts two stereo outputs with independent sample rates.
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.
