RME ADI-2 Pro FS 2-Channel High-End AD/DA Converter, Black Edition

RME’s reference AD/DA converter is a host of devices all put together into one unit, with a simple and mostly automated way of using it right out of the box. A unit with the industry’s biggest footprint per feature ratio, excellent tech specs, crystal clear and transparent sound signature, and two extremely powerful headphone outputs. The new ADI-2 Pro FS R Black Edition features the AK4493 chip, slightly improved specs and comes with the new extended Multi-Remote Control (MRC).

Key Features

• A high-end AD/DA converter in professional studio quality
• A double headphone amplifier in true high-end quality
• A USB DAC like no other - the most versatile and capable one
• A high-end AD/DA frontend and headphone amp for iPad / iPhone
• A multi-format converter (AES, SPDIF, ADAT) with monitoring function
