Microphones are analogue, speakers are analogue, storage is mostly digital and signal processing can be either analogue or digital, software or hardware based. At some point in the signal path, a high quality A/D converter is required, which faithfully reproduces analogue signals in the digital domain. Step up the new Drawmer A2D2... The A2D2 is a stereo A/D converter giving simultaneous dual stereo outputs at different selectable sample rates from 44.1kHz to 192kHz - so it is possible to have a main output at, say 192kHz with another at 44.1kHz as a low resolution copy. Features: [ Accurate 24 segment peak reading LED bar meters shows incoming signal level from -50dBfs to 0dBfs plus separate overload LEDs. [ Dual input configuration allows either a fully variable input level from -2dBu to +28dBu via front panel rotary controls or 24 turn precision presets for a fully calibrated input. [ Each digital output has selectable word length of 16 or 24 bits, with automatic dither generation. [ The internal low jitter clock generator is Grade 1 AES standard. [ External clock input. [ 3 word clock outputs to allow the A2D2 to act as master clock generator. [ Burr Brown analogue input stages. [ The A2D2 uses a linear power supply to minimise interference with the internal clocks. Technical Specifications: [ Input Level Range for 0dBFs: -2.0dBU to +28dBU [ Frequency Response: 20Hz to 20kHz +/-0.1dB [ Signal to Noise Ratio: > -101dB [ Sample Rate: 44.1, 48, 88.2, 96, 176.4, 192kHz/ 24Bit [ Digital Outputs: 2x AES/EBU, 2x S/PDIF, 2x TOSLink, 3x Word Clock [ Power Requirements: 115V or 230V, 16 VA [ Dimensions: 19", 1U [ Weight: 2.2 kg
