RME ADI-2 Pro EX Reference AD/DA Converter & Headphone Amplifier

The Next Generation of Absolute Audio Clarity

Experience the next evolutionary leap in reference-grade audio conversion. The RME ADI-2 Pro EX represents the pinnacle of RME’s legendary all-in-one converter engineering. Built upon the multi-award-winning foundation of the ADI-2 Pro FS R Black Edition, the EX version brings a completely redesigned chassis, massively upgraded output capabilities, and state-of-the-art hardware protection circuits to elite sound engineers, mastering studios, and ultra-high-end audiophiles.

Whether operating as a pristine studio-quality AD/DA converter, a dual-reference headphone amplifier, a multi-format digital converter (AES, SPDIF, ADAT), or an ultra-precise frontend for acoustic measurement systems, the ADI-2 Pro EX delivers unmatched transparency up to a staggering 768 kHz sample frequency.

What’s New in the EX Version?

RME has refined every detail of this new flagship unit to enhance cooling, performance, connectivity, and hardware longevity:

• Redesigned Ventilation Chassis: A larger enclosure featuring precision-engineered cooling vents, beautifully matching the aesthetic of the premium AD-2/4 Pro series while maximizing long-term component stability.

• Upgraded Desktop Aesthetics: Now standard with RME’s iconic chrome isolating feet (adapted from the ADI-2 DAC FS) for a refined, premium presence on your studio desk or high-fi rack.

• Lockable USB-C Port: Equipped with a rugged, modern lockable USB-C connection (USB 2.0 protocol, externally powered) to eliminate accidental disconnects. Includes a high-grade 1.8-meter matching cable.

• Synchronized TS Trigger Output: Integrated 3.5mm TS trigger out allows for seamless, synchronized remote power control of external amplifiers, active monitors, or peripheral gear.

• Boosted Headphone Amplification: Substantially increased output power across both balanced and unbalanced phone modes, driving even the most demanding high-impedance planar magnetic headphones with absolute ease.

• Next-Gen Hardware Protection: Features a new channel-independent DC protection circuit alongside an active, fuse-less Power Supply Unit (PSU) protection system that instantly guards against overvoltage and incorrect polarity.

• Hum-Free Semi-Grounded Design: Designed with a sophisticated semi-grounded topography to eliminate leakage currents entirely without introducing unwanted ground loops.

• Premium Power Solution: Packaged with the lockable, ultra-lightweight, and world-ready NT-RME-13 universal power supply.

Key Applications & Use Cases

• Mastering & Recording Studios: Pristine AD/DA conversion and clock architecture ensure that what you track and mix is exactly what you hear, keeping your sonic transients 100% intact.

• Hi-Fi Audiophile Listening: Use the class-leading dual headphone outputs to independently tune, EQ, and power separate sets of monitors or headphones with unmatched separation.

• Acoustic & Audio Measurement: An incredibly stable, ultra-linear analog stage provides an ideal, transparent hardware frontend for demanding reference measurements up to 768 kHz.

• Digital Format Interfacing: Fluidly route and bridge digital signals across AES/EBU, SPDIF, and ADAT ecosystems.
