The ADI-2 Pro from RME is a versatile reference-class AD/DA converter which can be used as a USB audio interface, USB DAC with Extreme Power headphone amplifiers, or format converter with digital monitoring. Housed in a compact, half-rack enclosure, it delivers pristine 32-bit/768 kHz audio quality to audio engineers and audiophiles alike, for studio, home, and mobile applications ranging from analog/digital recording, PCM/DSD recording and playback, precise audio measurements, or as a high-fidelity frontend and headphone amp for iPhone/iPad/Android devices.
The ADI-2 Pro is equipped with six input sources and eight output paths, for simultaneous 2-channel analog-to-digital input conversion and 4-channel digital-to-analog output conversion. The I/O options include two servo-balanced analog line inputs, two separate balanced and unbalanced analog outputs, one optical S/PDIF I/O which also supports two channels of ADAT operation, and, via the included digital breakout cable, one coaxial S/PDIF I/O and one AES/EBU I/O.
The unit supports all sample rates between 32 kHz and 768 kHz, and delivers a flat frequency response with an impressive 124 dBA signal-to-noise ratio. The company's SteadyClock III efficiently suppresses jitter in all clock modes, ensuring that the AD/DA conversion's sonic quality remains consistent, independently from the quality of the incoming clock signal.
The two Extreme Power headphone outputs provide high-end monitoring options optimized for low- and high-impedance headphones. They feature an Advanced Balanced mode which delivers a balanced signal path from the DAC straight to the phone, with optimized frequency response and a maximum output level of +28 dBu. A powerful DSP adds all kinds of useful audio processing, including 5-band parametric EQ, fast Bass/Treble adjustment, Crossfeed, and a sophisticated Loudness function.
The ADI-2 Pro features a high-resolution ISP LCD panel which eases operation and displays signal metering of all I/Os, current digital states of S/PDIF, AES, USB, a 30-band analyzer, and more. The unit can be used as a standalone, and operated with three push-button encoders and four buttons to access dedicated menus.
