The D2A Digital Converter from Henry Engineering is a 24-bit, high resolution digital-to-analog audio interface that can convert an AES-3 digital audio stream at up to 192 kHz to professional stereo analog outputs. It can be used in various professional environments, including broadcast stations, recording studios, performance venues, and more.
The unit's AES digital input is transformer isolated to prevent ground loops, hum, and noise. In addition, the D2A can auto-lock to standard sample rates from 32 to 192 kHz, and has a low-jitter clock recovery. Furthermore, its XLR outputs are calibrated to +4 dBu with over 22 dB of headroom. The front panel trimmers are designed to accurately calibrate your output levels. Notably, a Lock LED confirms a valid AES input signal.
A headphone amplifier is built into the D2A digital converter with separate volume control, and a 1/4" stereo headphone jack. In fact, the headphone output is buffered from the main line outputs and uses circuitry identical to the line outputs on the unit to ensure accurate monitoring.
The D2A converter is powered by an internal power supply that uses a toroid transformer and is triple-regulated to ensure a low noise floor. Meanwhile, the 40V rails enable operation with liberal headroom and freedom from clipping distortion. The D2A digital converter is 1/3 rack wide and can be mounted using an optional rack shelf.
