RME ADI-2 Pro EX 2-Channel 768 kHz AD/DA Converter

RME ADI-2 Pro EX 768 kHz AD/DA Converter

The RME ADI-2 Pro EX 768 kHz AD/DA Converter combines reference-grade analog-to-digital conversion, digital-to-analog conversion, USB audio interfacing, headphone amplification, and digital format conversion in one compact desktop unit. It supports PCM sample rates up to 768 kHz and DSD recording and playback for precision studio, mastering, and measurement workflows.

Designed for engineers, mastering rooms, hi-fi listeners, and technical audio users, the ADI-2 Pro EX is ideal for buying a professional AD/DA converter, upgrading a studio monitoring chain, or adding a high-end USB DAC and headphone amp. Its balanced analog I/O, digital connectivity, and onboard processing support demanding production and listening environments.

RME builds the ADI-2 Pro EX around SteadyClock FS clocking, AK5574 ADC conversion, AK4493 DAC conversion, and Class Compliant USB-C operation. Its DSP functions, dual Extreme Power headphone outputs, multi-format digital I/O, and hardware protection features make it a flexible reference tool for professional audio systems.
