The ADI-2 DAC is the home and hi-fi optimized version of the ADI-2 Pro, a studio AD/DA converter of the highest quality. With many fresh ideas, innovative features and numerous useful functions, the ADI-2 DAC quickly became the reference. Thanks to its combination of high-end DA conversion with two exceptional headphone IEM outputs and a remote control, it has received countless enthusiastic reviews for its sound, flexibility, and technical capabilities.

The current version of the ADI-2 DAC comes with an extended remote control, a further improved DA conversion and an adapted analog output stage for even better noise and distortion values. To address the home and HiFi users, RME exchanged some of the Pro's studio features with typical home and HiFi ones. With an adapted feature set and much simplified operation RME proudly presents the ADI-2 DAC. Built on the technology, concept and features of the ADI-2 Pro, the DAC concentrates on DA conversion in top high-end quality, along with two exceptional headphone and IEM outputs.

The DAC
Packed into the compact half 19” format factor, this little gem is filled with the finest high-end electronics, offering a reference class conversion from SPDIF coaxial, SPDIF optical (ADAT compatible) and USB to RCA, XLR, TRS and mini-TRS.

As the most versatile DAC available, the ADI-2 DAC offers balanced/unbalanced analog I/Os, an Extreme Power headphone output, a super low noise IEM output, SteadyClock FS, 4-stage hardware 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 playback. The SPDIF input signal can even be recorded via USB - as one would expect from RME the DAC is a true 2 channel Full Duplex audio interface.
