Ultra-Fidelity PCM/DSD 768 kHz DA Converter

The ADI-2 DAC includes an improved SteadyClock, a fine-tuned to perfection analog circuitry, new MRC remote control, Extreme Power headphone output and a very special IEM output. It has all the bells and whistles that made the ADI-2 Pro famous, including its perfectly transparent sound signature and full DSP processing with Bass, Treble, Loudness, 5 Band Parametric EQ, Crossfeed and much more. With its simplified operation and stunning design it is the ideal center piece from home listening up to studio reference playback.

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.

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 and Direct 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.

Improving DA
The updated ADI-2 DAC uses AKM's AK4493 in a special circuit variant developed by RME engineers that allows the chip to perform at its best. With noise levels of 123 dBA, distortion less than -120 dB, or THD+N of -116 dB, the device delivers outstanding measured values. Even the IEM output, with -118 dBu already the world's lowest noise headphone output, improves to a sensational -121 dBu. In addition, there is 4 dB of digital headroom, so that even high intersample peaks do not produce any audible distortion. Finally, the device now also offers a clear reserve in volume setting. +2.5 dB result in a still undistorted analog output signal.

New extended Multi-Remote Support (MRC)
The ADI-2 DAC remote control provides buttons for standby on/off, volume, balance, bass and treble, input selection (optical, coaxial, USB), mute, on/off loudness, bass/treble and EQ. In addition, there are four programmable buttons that provide access to 32 different functions and commands for maximum flexibility. There is no other converter or comparable device with such a sophisticated, easy to use and at the same time versatile remote control!

SteadyClock FS
With SteadyClock FS the focus was put on reducing the self jitter of SteadyClock to new lows, by improving its second, analog PLL circuit, and referencing both Direct Digital Synthesis and PLL to a low phase noise quartz crystal. The self jitter measured through DA conversion now reaches levels that usually are only available in master quartz clock mode, while SteadyClock still always runs in PLL mode - no matter if internal or external clock, sound is exactly the same (again). The low phase noise oscillator driving the updated circuit reaches jitter specs lower than a picosecond (ps), an area called FemtoSecond. Hence SteadyClock FS.
