RME ADI-2 Pro EX

RME ADI-2 Pro EX is the next-generation reference converter built on the foundation of the ADI-2 Pro FS R Black Edition, now with a redesigned chassis, upgraded headphone output power and comprehensive hardware protection circuits that address real-world reliability demands. In a single desktop unit it covers AD/DA conversion at studio reference level, dual headphone amplification, multi-format digital I/O (AES, S/PDIF, ADAT), DSD recording and direct DSD playback up to DSD 256 (11.2 MHz), and a measurement-grade frontend running up to 768 kHz PCM. The clock architecture and ultra-linear analog stages carry over unchanged — the same bedrock that made the ADI-2 Pro line a standard reference in mastering and acoustic measurement environments.

Hardware Protection Built for Production Reality

Channel-independent DC protection means a fault in one channel cannot take out the other — and cannot damage connected speakers or headphones. The fuse-less active PSU protection circuit detects reverse polarity and overvoltage before they reach the electronics, a meaningful step up from passive fuse-based designs. The TS trigger output lets you sequence power to external amplifiers or monitors automatically, removing the manual on/off ritual that protects speaker drivers. The lockable USB-C connector (USB 2.0, no bus power) with a 1.8 m cable included prevents accidental disconnection mid-session. The bundled NT-RME-13 power supply is semi-grounded to cut leakage current while avoiding ground loops — relevant in any studio with multiple grounded devices.

Dual Headphone Monitoring and Measurement Frontend

Increased output power in both unbalanced and balanced mode means the ADI-2 Pro EX drives low-impedance IEMs and high-impedance planar headphones without clipping the output stage at usable listening levels. Two independent headphone outputs with separate EQ, crossfeed and level control allow a recording engineer and a musician to monitor entirely different mixes simultaneously from one box. The 768 kHz PCM ceiling makes it a capable frontend for acoustic measurement and transducer testing, replacing standalone measurement hardware in many workflows. Compatibility with the new RME RM19-III rackmount bracket integrates the unit into 19" racks without adapters.
