The ADI-2 Pro EX represents the next evolution of RME’s all-in-one reference converter concept. Building on the proven design of the ADI-2 Pro FS R Black Edition, the new ADI-2 Pro EX offers professional users the famous, comprehensive functionality of the previous reference converter, but now updated with a redesigned chassis, enhanced output performance, and further comprehensive hardware protection.

Like the ADI-2 Pro, the ADI-2 Pro EX combines several devices in one: a high-end studio-quality AD/DA converter, a dual headphone amplifier, a multi-format converter (AES, SPDIF, ADAT) with monitoring features, a DSD recording and playback converter as well as an AD/DA frontend for audio measurements with up to 768 kHz sample frequency. With this range of functions, the new ADI-2 Pro EX presents itself as one of the most flexible converters on the market. The new ADI-2 Pro EX is equipped with the AK5574 analog-to-digital converter (ADC) and the AK4493 digital-to-analog converter (DAC).

What’s New in the EX Version

The EX version introduces substantial hardware and usability enhancements:

• Larger chassis with ventilation: Refined design and improved cooling efficiency, matching the ADI-2/4 Pro look.
• Upgraded with chrome feet from the ADI-2 DAC FS, adding a refined touch to the desktop setup.
• Lockable USB-C connection: Modern and robust (USB 2.0, no bus power), 1.8 m cable included.
• TS trigger output: Allows synchronized power control for external gear or amplifiers.
• Increased Phones output power in unbalanced and balanced mode.
• Channel-independent DC protection: New hardware circuit for maximum reliability.
• Advanced PSU protection: Fuse-less active circuitry detects and prevents wrong polarity and overvoltage conditions.
• Including lockable NT-RME-13: Light-weight, world-wide usable, universal power supply. Semi-grounded to prevent leakage current without ground-loop.

• Ultra-fidelity PCM/DSD 768 kHz AD/DA Converter

  As the most flexible converter available, the ADI-2 Pro EX offers balanced/unbalanced analog I/Os, double Extreme Power headphone outputs, 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).

• The RME ADI-2 Pro EX is an ultra-fidelity, multi-format 768 kHz AD/DA converter and USB audio interface. Retailing for around $2,499, it builds on the classic ADI-2 Pro FS R with a vented chassis matching the ADI-2/4 Pro style, increased headphone output power, a lockable USB-C port, and enhanced hardware protection circuits.
