The RME ADI-2/4 Pro SE is a flagship AD/DA converter and headphone amplifier, engineered for mastering-grade performance, high-end hi-fi, and reference-level studio use. Building upon the success of the ADI-2 Pro series, the ADI-2/4 Pro SE combines RME’s most advanced conversion technology with enhanced analogue circuitry, extended connectivity, and an upgraded design, making it a premium solution for critical audio tasks.
At its core, the ADI-2/4 Pro SE features dual AKM AK4493 DACs operating in a dual-mono configuration, providing superior channel separation, lower distortion, and increased signal-to-noise ratio. It supports PCM playback up to 768 kHz and DSD256 via USB and DSD128 via AES or SPDIF, delivering exceptional clarity across all modern high-resolution audio formats. On the input side, it includes two high-grade analogue-to-digital converters capable of capturing sources with extraordinary precision, enhanced further by RME’s proprietary SteadyClock FS technology for ultra-low jitter and clocking accuracy.
A standout feature of the RME ADI-2/4 Pro SE is its fully symmetrical analogue signal path, using discrete and servo-balanced I/O stages that maintain the highest fidelity throughout the conversion process. The front panel offers an intuitive user interface with a high-resolution colour display, rotary encoder, and direct access buttons for fast parameter adjustment. RME has also included user-definable DSP features such as a 5-band parametric EQ, crossfeed, and loudness compensation, making it easy to tailor playback to your environment or preferences.
Headphone amplification is equally refined, with two independent outputs: a dedicated Extreme Power output for over-ear models and an IEM output with ultra-low noise and near-zero output impedance. Each is optimised for the respective use-case, capable of driving everything from sensitive in-ear monitors to high-impedance studio headphones with ease and accuracy.
Connectivity is comprehensive: dual analogue mic/line combo inputs with phantom power, XLR and TRS balanced line outputs, SPDIF coaxial and optical I/O (switchable to ADAT), USB 2.0, and AES3. The RME ADI-2/4 Pro SE can operate in multiple modes, including USB interface, standalone converter, or digital monitor controller, and features robust power management for global use.
Housed in a robust, full-metal chassis with a sleek, modern design, the RME ADI-2/4 Pro SE reflects German engineering at its finest. Whether used in mastering studios, audiophile listening rooms, or high-precision measurement setups, it delivers uncompromising audio quality, reliability, and versatility.
