Extraordinarily Flexible 2-channel High-end AD/DA Converter

The RME ADI-2 is a both compact and extremely flexible 2-channel Hi-End AD/DA-converter. The small 9.5" RME ADI-2 offers top notch AD/DA-conversion from/to SPDIF, AES and ADAT, at up to 192kHz. Its ability to use SPDIF, AES and ADAT format provides outstanding compatibility.

RME ADI-2 at a Glance:
  • Balanced inputs and outputs, and monitoring via headphone out.
  • SteadyClock for optimal converter quality, 24-bit/192kHz.
  • Digital Connectivity
  • Clear layout makes the ADI-2 easy to use out of the box.
  • Runs on a wide range of power supplied.
Balanced inputs and outputs

The ADI-2 is equipped with a balanced stereo line input via two Neutrik XLR/phones combo jacks, a balanced stereo line output with XLR plus separate and simultaneously active phone jacks, as well as an adjustable headphone output.


The analog inputs and outputs use the same circuit design as RME's famous ADI-8, guaranteeing outstandingly low noise and distortion. Three different settings for the input and output levels each provide perfect compatibility on analog domain. A further highlight is SteadyClock, a proprietary clock technology for maximum jitter suppression. SteadyClock guarantees superb sound quality completely independent from the quality of the current reference clock. The ADI-2 uses the latest generation of AD/DA-converters capable of up to 192kHz sampling frequency at a S/N ratio of 110dB.

Digital Connectivity

The RME ADI-2 has more to offer than tremendous sound, it also gives you exciting digital connectivity. The RME ADI-2's transformer-balanced coaxial (RCA) SPDIF I/O has switchable Channel Status to make it fully AES/EBU compatible. The optical TOSlink I/Os can handle up to 192kHz and also serve as ADAT I/Os with up to 96kHz sample rate. You can even use the RME ADI-2's SPDIF input and ADAT output or vice versa in AD/DA mode.

Clear Layout and Distinct Labeling

The clear layout and the distinct labeling of the RME ADI-2's front panel with its functional buttons, the informative status displays, a six-LED level meter as well as the tidy functional back panel make the RME ADI-2 easy to operate the ADI-2 right out of the box. Protective rack handles and a strain-relief for power cord and audio cables are further useful details that make the ADI-2 even more unique.

Wide Range Of Power

Following the 'Universal Power Supply' philosophy of RME's Digiface, Multiface, QuadMic and OctaMic, the ADI-2 comes with an external switching power supply. Its additional internal switching power supply has been specially designed and optimized for audio applications. It accepts any voltage from 7 to 30 V, be it AC or DC, and even runs on batteries and rechargeable batteries.

RME ADI-2 Features:
  • 192kHz sampling frequency at a S/N ratio of 110dB.

Much clearer recordings

I'd been using the built-in converters on my Focusrite Saffire24 (with the Black Lion mod). I decided to up my game and get this ADC. I was not attracted to the Babyface CUTE form factor and have no attraction to Apple-ish things, so I bought the ADI-2. It was a learning curve to get the ADI-2 to work through the Saffire's ADAT In port (Saffire has cryptic routing software, and the buttons on the front of the ADI-2 are kind of mysterious also), but I was pleased to hear that the vocals are now quite a bit clearer than the old ones, which sound almost like there was a wool sock wrapped around the mic. Now I can lay down tracks that are pretty close to studio quality and I didn't have to spend a lot of money.

No Thing Can Beat It On The Price

i was using tc electronic impact twin it was not so bad but after getting this and open an old session i knew the truth that i was wrong in some movement in my mix .... i recommend this for any one you will get more details and wide stereo image

I bought this unit to improve the converters that I have on my impact twin. I'm using Rokit 8's and the difference was huge between the converters. These make everything so clear. I can't imagine going back to my old converters.You do not need a monitor controller for these. It is possible to adjust the level of the outputs via the headphone knob.

Amazing product

I give this 5 stars. I was using a neve portico with a brauner phanthera, into a digi002. And since upgrading my converter to this the sound has improved so much. I felt like all the digital grain and harshness just vanished on the a/d and on the d/a no more mud and grainyness coming from the speakers. This thing really does blow away the digi 002 in terms of converters.

What an amazing little box.

I can't say enough good things about this converter. If you mix outside your DAW and want to bypass your on-board converters then the ADI-2 is a must have. Even at 48k it sounds unbelievable. I've made a million mixes without a high quality converter but no more. Go outside your box to your analogue gear and back without losing anything. You also get 2 channels of high quality tracking to your DAW.
