The RME Digiface AES is a versatile USB 2.0 interface that provides professional-quality audio recording and playback. It has 14 inputs and 16 outputs, including two analogue inputs and four analogue outputs. The digital I/O section is complemented by XLR and TRS phones. 

The RME Digiface AES is equipped with TotalMix FX, which offers flexible playback and monitoring. It also comes with DIGICheck Analyzer, a tool enabling users to measure and analyze the digital data feed precisely.

All 14 input and playback channels may be routed and mixed independently to all 16 physical outputs with the TotalMix FX DSP mixer. Furthermore, the Digiface AES has luxury features like a 3-band parametric EQ, MS processing, and phase reversal for each input and output channel. In addition, users may construct monitor mixes with EQ and Reverb using the latency-free monitoring capability.

The Digiface AES audio interface may be powered by USB or by the provided external DC-power supply for stand-alone operation or as a backup fail-safe against potential computer problems. The Babyface Pro FS's proven mic/line preamps in XLR combo mode are used for the primary inputs, with individually switchable 48V phantom power.

The Digiface AES includes an AES/EBU input and output via XLR, SPDIF coax, SPDIF optical, or 8-channel ADAT. All I/Os can be used at the same time. The kit is completed with MIDI I/O through a concurrent breakout connection.

TotalMix Remote is a network control programme with all RME audio interfaces and sound cards. TotalMix Remote controls Digiface AES's hardware mixer and effects section through a network-connected PC, Mac, or Apple iPad. In addition, the inbuilt SRC (Sample Rate Converter) may be switched to one of the three inputs to overcome clocking difficulties and adjust to different sample rates.

The Digiface AES features RME's latest digital clocking and jitter rejection technology, 'SteadyClock FS.' SteadyClock FS reduces intrinsic jitter to a new all-time low, allowing clock modes to provide excellent performance and high-quality analogue conversion. Moreover, the device's clocking and format conversion occur without signal loss, ensuring the sonic image is never degraded.

The front panel provides convenient, direct access and control of all features. In addition, the device has four select keys, an encoder, a high-resolution display with clear colour output, and a well-designed interface.
