RME's anniversary reference AD/DA converter is a host of devices all put together into one unit, with a simple and mostly automated way of using it right out of the box. A unit with the industry's biggest footprint per feature ratio, excellent tech specs, crystal clear and transparent sound signature, and two extremely powerful headphone outputs.

• High-end AD/DA converter in professional studio quality
• Double headphone amplifier in true high-end quality
• AD/DA frontend and headphone amp for iPad / iPhone
• Multi-format converter (AES, SPDIF, ADAT) with monitoring function
• DSD record and playback solution
• AD/DA frontend for audio measurement at up to 768 kHz sample rate

Ultra-fidelity PCM/DSD 768 kHz AD/DA Converter
As the most flexible converter available, the ADI-2 Pro offers balanced/unbalanced analog I/Os, double Extreme Power headphone outputs, SteadyClock III, 4-stage hardware input and output level control, DSP-based signal processing, external power supply operation, Class Compliant USB compatibility, sample rates up to 768 kHz as well as DSD record and Direct DSD playback (256 / 11.2 MHz).

Analog or Digital - Options Galore
The ADI-2 Pro includes two servo-balanced analog inputs on combo XLR / TRS jacks, two separate balanced and unbalanced outputs on XLR and TS, two stereo Extreme Power headphone outputs on the front, an optical SPDIF I/O that also understands ADAT, and coaxial SPDIF (RCA) and AES I/O (XLR) via an included breakout cable. This universal set of I/O options offers superior quality and flexible connectivity to those who take a no-compromise approach to audio.

The USB 2.0 port is fully Class Compliant (UAC 2) for connection with compatible iOS devices, and is also used for firmware updates. Including an external switched power supply with lockable connector, the ADI-2 Pro can be easily powered from battery, opening up mobile applications as well as galvanically isolated use cases.

As a computer interface the ADI-2 Pro offers a stereo (2 in / 2 out) and a multichannel mode (6 in / 8 out). Compatibility with Mac OS X comes right out of the box. Under Windows the ADI-2 Pro uses RME's MADIface series driver, for full WDM and ASIO compatibility and highest performance.

Perfect Sound Capture and Reproduction
Aiming for the absolute reference sound, any detail in the ADI-2 Pro is special and has its own story. The main PCB is an extraordinary 10 layer design with custom copper thickness, guaranteeing finest undisturbed sound as well as ample but separated power for the phones outputs. Internal power supply stages and precise regulators use a super-low-noise design to not degrade performance through the power rails. Selected SoundPlus operational amplifiers maintain highest SNR, lowest THD and high slew rate under all conditions. The whole analog circuit design is fully symmetrical and balanced throughout - and DC-coupled. The only capacitors in the signal path perform DC protection at the analog input sockets, and have been carefully selected to avoid any sonic impact.

The 4-channel AD-converter, supporting 786 kHz sample rate and DSD recording, is used in a dual mono design, with 3 dB improved signal to noise ratio. Two premium DACs are used for two separate stereo outputs. Internal audio processing like EQs, Crossfeed and spectral analysis, is done by a high performance DSP with 2.17 Giga FLOPS (2882 MIPS), delivering enough computing power to work even at 768 kHz sample rate.
