Functionality for the Audio Professional & Audiophile
The RME ADI-2 Pro FS R boasts high-grade components and intelligent circuitry throughout its half-rack design. RME has incorporated many unique features, not found on any comparable devices:
- 5-band parametric EQs for individual phones compensation
- Adjustable Bass/Treble controls with quick access
- Binaural crossfeed function
- Adjustable Loudness Filter
- Selectable AD/DA Filters
- Four discrete I/O reference levels
- Auto reference level setting
- Extreme Power Headphone Outputs
- Auto balanced phones mode
The Extreme Power Headphone Outputs bring the full performance of the premium DAC to the phone jack — Even with low-impedance headphones. It excels with 0.1-ohm output impedance, a maximum output level of +22 dBu, and a maximum output power of 1.5 Watts — Per Channel!
Two, fully separate stereo headphone outputs deliver the same 12- dBA SNR performance as the line outputs, for a full hum and noise-free listening experience. The Extreme Power design also incorporates current limiting, power surveillance, overload detection and DC protection. A low power mode and a high power mode are provided, for a perfect match from IEMs up to planar magnetic headphones.
A new Advanced Balanced mode removes most limitations of standard balanced operation and turns this mode into a fully new experience. This mode delivers a balanced signal path from the DAC straight to the phone, with 3 dB gain in Signal to Noise Ratio, smoothed out deviations in components, optimized frequency response, super low output impedance (0.2 ohms) and maximum output level of +28 dBu.
Included with the RME ADI-2 Pro FS R is a remote control that provides buttons for standby on/off, volume, balance, bass and treble, input selection (optical, coaxial, USB) mute, on/off loudness, bass/treble and EQ. There are also four programmable buttons that provide access to 52 different functions and commands for maximum flexibility.
- M/S Processing
- Stereo width & Phrase reversal up

Ultra-fidelity PCM/DSD 768 kHz AD/DA Converter
As the most flexible converter available, the RME ADI-2 Pro FS R offers balanced/unbalanced analog I/Os, SteadyClock FS, 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).
It includes two servo-balanced analog inputs on combo XLR / TRS jacks, two separate balanced and unbalanced outputs on XLR and TRS, 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 a lockable connector, the RME ADI-2 Pro FS R can be easily powered from a battery, opening up mobile applications as well as galvanically isolated use cases.
Compatibility with Mac OS X comes right out of the box. Under Windows the ADI-2 Pro FS R 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 RME ADI-2 Pro FS R is special and has its own story. The main PCB is an extraordinary 10-layer design with custom copper thickness, guaranteeing the finest undisturbed sound as well as ample but separated power for the phones outputs.
The 4-channel AD-converter, supporting 768 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.
For easy operation a high quality Sample Rate Converter has been added, switchable to the AES or SPDIF input, solving any clocking problem between those. And RME’s latest SteadyClock FS technology ensures perfect jitter reduction and stable clocking, no matter if internal or external clocks are used. This helps to optimize recordings and mixes because the soundstage has more depth and clarity. The RME ADI-2 Pro FS R delivers listeners excellent performance and high-quality analog conversion.

F.A.Q
How do you connect an RME ADI-2 to a computer?
Use the Standard USB socket to connect your RME ADI-2 Pro FS R to a computer. The ADI-2 Pro FS R operates as a Class Compliant device in 2-channel mode or 8-channel mode and can be directly used with Mac OS X and iOS. For Windows, the RME MADIface series driver adds WDM and ASIO.
Are there firmware updates for RME products?
Yes! Firmware updates are available on RME's website under Downloads, USB. If there is a firmware update for your unit, download the tool that matches your operating system, then unpack the zipped archive, and following the directions to begin the process of updating your unit.
What is DSP?
DSP stands for Digital Signal Processing or a Digital Sound Processor. DSP technology is found in almost every consumer audio device on the market, and this technology acts like a computer's CPU. It's where all the processing occurs for digital audio signals. DSP is usually designed on a chip - and like all chips - can come in a variety of sizes, performance variations, and prices. More powerful chips can "do the math" quicker and more efficiently than lower-tiered DSP chips, so performance will correspond directly to the price. All of this technology is built to make your music sound better. Your wireless headphones, standalone DACs, and even your room correction gear all have DSP as an integral part of making your audio sound the best it can.
What is DigiCheck?
DigiCheck is a free software tool on Windows that is offered with any RME audio interface that analyzes levels, channel status and bit stream content, the true hardware sample rate, and much more. It's the secret weapon to high-resolution audio measurements, great for metering, testing, measuring and analyzing digital audio streams.
