RME  kallar det Ultra Fidelity och inte High Fidelity. Med 768 kHz PSM/DSD  klocka konverterar denna lilla enhet både analog signal och digital  signal via usb eller AES3, coax/digital ADAT till analog signal av  högsta möjliga ljudkvalitet. Signalen förstärks enastående  hörlursförstärkare som har flera olika lägen beroende på om hörlurarna  är lätt eller trögdrivna. Det finns även en IEM output som betydligt  sänker signalen passande för känsliga IEM system. Varje utgång har bl.a  Gain, parametrisk EQ sk. crossfeed och loudness. MRC remote medföljer.

New Experience in Sound and Quality
RME’s  reference AD/DA converter is a host of devices all put together into  one unit, with a simple and mostly automated way of using it right out  of the box. A unit with the industry’s biggest footprint per feature  ratio, excellent tech specs, crystal clear and transparent sound  signature, and two extremely powerful headphone outputs. The new ADI-2  Pro FS R Black Edition features the AK4493 chip, slightly improved specs  and comes with the new extended Multi-Remote Control (MRC).

Ultra-fidelity PCM/DSD 768 kHz AD/DA Converter
As  the most flexible converter available, 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).

 

Analog or Digital - Options Galore
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.

Perfect Sound Capture and Reproduction
Aiming for  the absolute reference sound, any detail in the ADI-2 Pro is special  and has its own story. The main PCB is an extraordinary 10 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 under all conditions. The whole analog circuit design is fully  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 carefully selected to avoid any 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. 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 III technology  ensures perfect jitter reduction and stable clocking, no matter if  internal or external clocks are used.

High Resolution Display Operation
RME have incorporated many  unique features, not found on any comparable devices, like 5-band  parametric EQs for fully individual phones compensation, adjustable  Bass/Treble controls with quick access, a binaural crossfeed function,  adjustable loudness filter, selectable AD/DA filters, four discrete I/O  reference levels, auto reference level setting, auto balanced phones  mode, and many more. The display is not only used to control the unit,  but also shows warning and guidance messages.

Professional features such as M/S Processing, stereo width and phase  reversal up to full control and storage of all settings are included, as  well as RME’s famous Spectral Analyzer, a 30-band biquad filtered  analysis tool offering unprecedented musical visualization, perfectly  complementing the high-resolution IPS display.


 

Extreme Power Headphone Outputs
There is no use  in boasting about -110 dB THD, when such values are not available in  real world operation - for example when a 32 ohm headphone is connected.  RME's engineers therefore designed a new headphone output stage that  brings the full performance of the premium DAC to the phone jack - even  when using low impedance headphones. The Extreme Power design 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! The two, fully  separated stereo headphone outputs deliver the same 120 dBA SNR  performance as the line outputs, for a full hum and noise free listening  experience. THD is far below -100 dB (0.001%) even at full power, for  the most clear and detailed soundstage possible. 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 IEM up to planar.

Having two stereo outputs, balanced headphone operation is possible.  As RME's engineers were not satisfied with the existing techniques they  developed a new Advanced Balanced mode for the ADI-2 Pro, that removes  most limitations of standard balanced operation, and turns this mode  into a a fully new experience. The exclusive Advanced Balanced 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 a maximum output level of +28 (twenty eight) dBu.


 

The Reference Converter
The ADI-2 Pro is RME’s  reference AD/DA converter, USB DAC, USB interface and headphone amp.  It’s numerous use cases make it an ideal choice in many fields, from the  home user appreciating innovative solutions offering highest sound  quality, the studio owner asking for reference AD/DA conversion, the  Hi-Fi enthusiast demanding a flexible yet high-end headphone amplifier,  up to the industry using the portable device as front-end for  measurement systems.
 

New extended Multi-Remote Support (MRC)
The ADI-2  Pro 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 52 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!
