RME ADI-2 Pro Converter

ADI-2 Pro USB 2.0 24 Bit / 768 kHz, 2 in / 4 out Hi-Performance AD/DA Converter 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) 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. 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 The main PCB is an extraordinary ten-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. The whole analog circuit design is 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 selected to avoid 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. ...
