Styled in a black finish, the RME ADI-2 Pro FSR BE is a versatile reference-class AD/DA converter that can be used as a USB audio interface, a USB DAC with Extreme Power headphone amplifiers, or as a 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 use as a high-fidelity front-end and headphone amp for iPhone/iPad or other mobile devices.
The ADI-2 Pro FSR BE 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 and 768 kHz and delivers a flat frequency response with an impressive 124 dBA signal-to-noise ratio. The company's SteadyClock technology 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.
