RME ADI-2 FS, 2-Channel Hi-Performance AD/DA-Converter

RME ADI-2 FS, 2-Channel Hi-Performance AD/DA-Converter

The ADI-2 FS is a compact and extremely flexible 2-channel Hi-End AD/DA-converter. The small 9.5" unit offers first-class AD/DA-conversion from/to SPDIF, AES and ADAT, at up to 192 kHz. Its ability to use SPDIF, AES and ADAT format provides outstanding compatibility. Whatever it is - simply get connected!

Balanced analog inputs and outputs, monitoring via headphone output, SteadyClock FS for optimal conversion quality, 3-stage hardware input and output level control and the additional modes D-D and A-A turn the ADI-2 FS into a universal tool and a flexible problem solver. Its pro-class sound qualifies it also as extension for other premium converters.

The ADI-2 FS is equipped with two servo-balanced analog line inputs via XLR/phones combo jacks, simultaneously usable balanced XLR and unbalanced phone jacks, an adjustable High Power headphone output on the front, an ADAT compatible optical SPDIF I/O, and a coaxial SPDIF I/O (RCA, AES/EBU compatible). These extensive connectivity options provide most flexible and uncompromised signal transmission.

The analog inputs use the advanced circuit design of the highly acclaimed ADI-2 Pro, thus offering outstandingly low noise and distortion as well as an extended frequency response. Three different settings for input and output levels provide perfect compatibility in the analog domain. A further highlight is SteadyClock FS, RMEs latest clock technology for maximum jitter suppression and lowest self-jitter. It guarantees superb sound quality completely independent from the quality of the current reference clock. The ADI-2 FS also uses the conversion technology of the ADI-2 Pro: the AK557x family and the AK4490 not only offer 192 kHz sampling frequency and lowest distortion, but also a dynamic range of 120 dBA.

But the ADI-2 has more to offer than tremendous sound. It also provides exciting digital connectivity. Its coaxial RCA SPDIF I/O has a switchable Channel Status to make it fully AES/EBU compatible (cable adapter required). The optical TOSLINK I/Os can handle up to 192 kHz and also serve as ADAT I/O, even at 192 kHz. An operation with SPDIF input and ADAT output or vice versa is supported, in both AD/DA and D-D mode.
