Rme - ADI-2/4 Pro EX

Designed for the mastering studio, the RME ADI-2/4 Pro EX converter utilises the latest ESS converters, with a resolution of up to 32-bit / 768 kHz. Its signal-to-noise ratio of 127 dBA and low distortion ensure accurate reproduction, which is particularly useful when mixing decisions depend on subtle differences.

For headphone monitoring, the Extreme Power amplification offers three modes optimised for headphones and in-ear monitors, with connection detection and dedicated protection circuits. The headphone outputs can operate in balanced mode without muting the rear outputs, making it easier to monitor multiple audio paths. The very low noise floor enhances the perception of detail, even with sensitive earphones.

Analogue and digital connections make it easy to integrate the ADI-2/4 Pro EX into a variety of set-ups, from XLR and TRS sources to AES, SPDIF and ADAT formats. Two analogue inputs and four digital-to-analogue output channels cover a range of conversion, monitoring and playback needs. The independent outputs also allow separate signals to be sent to headphones and equipment connected to the rear panel.

The on-board DSP allows you to fine-tune your listening experience without the need for additional external devices, thanks to a 5-band parametric equaliser, quick bass and treble adjustments, Crossfeed and the Loudness function. The 30-band analyser and peak indicators help you monitor the signal in real time. The IPS display brings all this information together in a clear interface, which is useful for keeping track of the settings.

On a computer, the USB-C audio interface operates in 2-in/2-out stereo mode or 6-in/8-out multichannel mode. Native compatibility covers macOS, iOS, Linux and Windows 10 from version 1709 onwards, with ASIO and WDM support on Windows via the MADIface driver. The DigiCheck software is used to measure and analyse digital audio streams, whilst ADI-2 Remote makes it easy to adjust settings.

New features in this version include a lockable USB-C connector, enhanced electrical protection and factory calibration of the internal clock to ±1 ppm. Fine-tuning of the sampling rate also enables precise synchronisation with external devices. For vinyl sources, RIAA equalisation in Line mode and selectable input impedances of 47 kΩ or 94 kΩ expand the digitisation options.
