<\/div>\nNearly 30 years of engineering excellence. A new benchmark in conversion.<\/h2>\n
Since 1996, RME has earned its reputation among audio professionals for delivering exceptionally detailed, transparent and dependable sound. Now, that experience has culminated in what is RME’s best-sounding converter to date<\/strong>: the new ADI-2\/4 Pro EX<\/a>.<\/p>\n Combining upgraded ESS conversion, the latest SteadyClock EX technology and an impressive range of tools for mixing, mastering and high-resolution audio archiving, the ADI-2\/4 Pro EX represents a significant evolution of RME’s reference-class converter and mastering hub.<\/p>\n But this is much more than a USB-DAC – it’s a powerful, reference-class conversion and monitoring hub designed for engineers who need to hear every detail and make confident decisions every time.<\/p>\n <\/p>\n At the heart of the ADI-2\/4 Pro EX are its new ESS converters: the ESS9823Pro ADC and ESS9039Q2M DAC. These bring improved noise and distortion performance over the previous model, delivering the kind of clarity, precision and transparency that critical listening demands.<\/p>\n The analogue inputs<\/strong> deliver an impressive signal-to-noise ratio of up to 127 dBA<\/strong>, with THD of just 0.000045%<\/strong> and THD+N of 0.000112%<\/strong>. With channel separation exceeding 130 dB, the ADC section is engineered to capture even the finest details with exceptional accuracy.<\/p>\n For engineers working with analogue mixers, consoles and outboard effects, this means being able to capture their sound with outstanding fidelity, preserving the detail, dynamics and character of the original signal. Whether you’re printing a mix bus, recording a hardware processing chain or archiving a valuable analogue source, the ADI-2\/4 Pro EX provides an exceptionally clean and accurate route into the digital domain.<\/p>\n The analogue outputs<\/strong> are equally impressive, achieving up to 126 dBA signal-to-noise ratio<\/strong>, with THD as low as 0.0000316%<\/strong> and THD+N of 0.00011%<\/strong>. Maximum XLR output level reaches +26.5 dBu<\/strong>, providing substantial headroom for professional studio equipment.<\/p>\n That headroom is particularly valuable when feeding high-end analogue processors, consoles and monitoring systems – the ADI-2\/4 Pro EX delivers a powerful and exceptionally clean signal, helping you get the best from the equipment downstream without compromising audio quality.<\/p>\n The quality of your conversion ultimately determines what you hear: with its exceptionally low noise and distortion, the ADI-2\/4 Pro EX provides a highly transparent signal path to your studio monitors and headphones, allowing you to hear fine details, subtle processing changes to EQ and reverb, and make the smallest mix decisions with the utmost confidence.<\/p>\n<\/div>\n <\/p>\n <\/p>\n Conversion performance is only part of the story. With clocking plays a vital role in the accuracy and stability of digital audio, RME\u2019s introduced the now critically-acclaimed SteadyClock FS with its original ADI-2 Pro mode. Now with the ADI-2\/4 Pro EX, RME takes things one step further with SteadyClock EX<\/strong>, the latest evolution of RME’s renowned clocking technology.<\/p>\n Factory-calibrated to an accuracy of \u00b11 ppm<\/strong>, SteadyClock EX provides an exceptionally precise internal reference. It also offers fine user adjustment, with a \u00b150 ppm trim range in 0.1 ppm steps, and RME’s distinctive ‘Sync without Sync’ capability.<\/p>\n For studios working across multiple digital sources and formats, robust clocking and jitter suppression are essential. SteadyClock EX is engineered to maintain reliable synchronisation and minimise the influence of incoming clock jitter, helping ensure that signals remain precise and dependable throughout the system.<\/p>\n <\/p>\n At its core, the ADI-2\/4 Pro EX is no doubt a specialist device: a high-end two-channel converter, designed to capture and reproduce audio with extraordinary accuracy. But its capabilities extend beyond conversion alone, with the flexibility to make it a valuable centrepiece in mastering rooms, high-end mix studios and smaller professional setups.<\/p>\n High-quality balanced analogue inputs and outputs provide the performance required for critical recording and playback, while digital connectivity includes AES\/EBU, coaxial and optical S\/PDIF, and an optical input compatible with ADAT. USB-C connectivity also allows the ADI-2\/4 Pro EX to operate as a standalone, class-compliant audio interface with any DAW, or integrate with an existing interface-based system via ADAT.<\/p>\n<\/div>\n <\/p>\n <\/p>\n For mix and mastering engineers, this opens up a range of possibilities. The unit can sit at the heart of a hybrid setup, providing the conversion between a DAW and external analogue processors, while also serving as a high-quality headphone and monitor controller. Its onboard parametric EQ, configurable routing and extensive monitoring options add further flexibility, allowing engineers to tailor the listening environment and signal path to suit their workflow.<\/p>\n RME’s software remote also provides comprehensive access to the unit’s settings, routing, EQ and monitoring functions directly from a Mac or PC, while the customisable wireless remote allows for essential controls when the device is racked away from the listening position.<\/p>\n The result is a product with a clear focus on reference-class two-channel conversion, but with the connectivity, processing and control to play a much broader role in the modern studio.<\/p>\n <\/p>\n <\/p>\n Accurate monitoring doesn’t stop at the main speakers. The ADI-2\/4 Pro EX also features powerful headphone amplification, giving engineers another highly revealing way to assess their work.<\/p>\n Its balanced headphone output delivers up to 3.85 W per channel into 32 \u03a9<\/strong>, with up to 1.15 W per channel into 300 \u03a9,<\/strong> providing substantial drive for even the most demanding of headphones, while selectable output modes help accommodate different headphone types and sensitivities.<\/p>\n With exceptionally low output impedance and high signal-to-noise performance, the headphone stages are designed to deliver clean, controlled and detailed monitoring.<\/p>\n Whether you’re checking edits, evaluating low-level details, working late without speakers or carrying out critical listening, the ADI-2\/4 Pro EX gives you a serious monitoring option.<\/p>\n<\/div>\n <\/p>\n <\/p>\n One of the most interesting additions is the integrated RIAA equalisation<\/strong>, making the ADI-2\/4 Pro EX a highly capable solution for vinyl enthusiasts and professional archivists alike. Vinyl archiving becomes surprisingly straightforward, allowing for compatible Moving Magnet (MM) cartridges to be connected directly to its analogue inputs.<\/p>\n Selectable input gain and balanced input impedance options add further flexibility, including 47 k\u03a9 and 94 k\u03a9 settings for compatible cartridge configurations.<\/p>\n Simply connect the turntable’s left and right RCA outputs to the ADI-2\/4 Pro EX using RCA-to-TS adapters, attach the turntable’s earth wire to the rear-panel GND screw, and enable RIAA mode in the input settings. Select the appropriate gain for your cartridge – +26 dB is a good starting point for most MM pickups – and you’re ready to record.<\/p>\n The ADI-2\/4 Pro EX takes care of the necessary RIAA equalisation internally, with exceptional accuracy of better than \u00b10.05 dB across 20 Hz\u201320 kHz. Its adjustable gain accommodates different cartridge output levels, while the input meters make it easy to check recording levels and avoid overload.<\/p>\n Prefer using a dedicated phono preamp, mixer or amplifier with a phono stage? No problem. Simply connect its line-level outputs to the ADI-2\/4 Pro EX, leave the internal RIAA processing switched off, and select the appropriate input reference level to match the connected equipment.<\/p>\n Once connected, select the ADI-2\/4 Pro EX as your recording device in your preferred audio software and choose your desired recording format. For high-resolution PCM archiving, sample rates up to 192 kHz are supported when using the internal RIAA mode, making it possible to create exceptionally detailed digital transfers of your vinyl collection.<\/p>\n <\/p>\n The ADI-2\/4 Pro EX also brings a number of practical additions compared with its predecessor. A lockable USB-C connection provides a secure link to a Mac, PC or iPad, whilst improved hardware protection includes enhanced headphone DC protection, independent channel safety, and advanced power-supply protection.<\/p>\n There’s also a dedicated grounding screw, compatibility with RME’s RM19-III rackmount<\/a>, and extended reference-level settings down to -35 dBu, providing greater flexibility when integrating equipment with lower-level analogue outputs into your studio setup.<\/p>\n As mentioned above, RME’s dedicated software remote gives you full control of the ADI-2\/4 Pro EX from your Mac or PC via USB<\/strong>, providing convenient access to its extensive settings, routing, EQ and monitoring functions directly from your computer, removing the need for front panel menu-diving.\u00a0<\/p>\n Then there’s the customisable wireless remote – whether you’re adjusting monitoring levels, switching between inputs and saved configurations, or fine-tuning your sound, the ADI-2\/4 Pro EX gives you the flexibility to work the way you want.<\/p>\n<\/div>\n <\/p>\n <\/p>\n RME’s commitment to precision doesn’t stop at the hardware. The ADI-2\/4 Pro EX also works with DIGICheck NG<\/strong>, RME’s measurement and analysis software for supported RME hardware, giving engineers an extensive collection of tools to examine audio in detail.<\/p>\n From classic VU metering<\/strong> and precise level measurement to stereo analysis, frequency measurement and real-time spectral visualisation, DIGICheck NG provides valuable insight into what’s happening across your signal chain.<\/p>\n Its tools include a Vector Audio Scope for examining stereo image and phase correlation, a Spectroscope with scrolling spectrogram display, an Oscilloscope and Frequency Measurement, alongside a range of metering and analysis instruments.<\/p>\n Whether you’re checking stereo width and phase relationships, monitoring levels through a mastering chain, investigating frequency content or examining the dynamics of a mix, DIGICheck NG puts a powerful suite of analysis tools at your fingertips.<\/p>\n It’s another way RME gives engineers more than just outstanding conversion: a complete set of tools to help them make informed, confident decisions about their audio.<\/p>\n <\/p>\n <\/p>\n The ADI-2\/4 Pro EX brings together upgraded ESS conversion, SteadyClock EX, powerful headphone amplification, flexible connectivity and sophisticated processing in one exceptionally capable unit.<\/p>\n For mastering engineers, mix engineers, studio owners and serious audio enthusiasts, it offers a compelling combination of reference-class performance and everyday practicality.
