RME Digiface AES - 30-Channel, 192 kHz
USB Bus-powered Audio Interface

The RME Digiface AES is a professional 14 input and 16 output channel USB 2.0 interface with 2 x Mic/Line analogue input channels and 4 x analogue output channels (2 XLR, one TRS phones) to complement its digital I/O section.

With an excellent set of digital connectivity, SteadyClock FS, full stand-alone operation and built-in parametric EQ, the Digiface AES shines as the perfect all-in-one solution for recording and playback of digital and analogue sources, as well as flexible playback/monitoring via TotalMix FX.

Bus-power compatibility meets flexible Analogue I/O Performance

The Digiface AES can be bus-powered over USB, doing away with the need for an external power supply. At the same time, the Digiface AES also ships with an included external DC-power supply for use in stand-alone operation, or as a secondary fail-safe against any potential computer failures.

For the main inputs RME uses the proven mic/line preamps in XLR combo configuration of the Babyface Pro FS. Two digitally controlled preamps provide individually switchable 48V phantom power. These circuits feature a gain range of 75 dB, adjustable in steps of 1 dB, including a relay-driven PAD, resulting in exceptional EIN (Equivalent Input Noise) performance as well as line overload protection, and enough gain for even the lowest level microphones.

On the back of the Digiface AES there are 2 balanced analogue outputs via XLR male to drive power amps, active monitor speakers, or recordings. The headphone output allows additional and independent high quality monitoring, providing sufficient output power and volume on high and low impedance headphones.

Connectivity & Features

Click image to enlarge

Versatile Digital Input and Output Connectivity

The comprehensive set of digital I/Os, centered around an AES/EBU input and output via XLR, also includes SPDIF coax, SPDIF optical or 8-channel ADAT.

All I/Os can be used simultaneously, turning the unit into a swiss-army-knife interface that receives and sends all common digital audio formats.

MIDI I/O via an included breakout cable completes the package.

Integrated SRC (Sample Rate Converter)

An integrated SRC (Sample Rate Converter) can be switched to one of the three inputs to solve clocking issues and to adapt to other sample rates.

This allows, for example, the device to be AES clock-synchronized from the main source and to listen to SPDIF independently at the same time.

Full Stand-alone Functionality

Convenient, direct access and control of all features is available directly from the front panel. Four select keys; an encoder; a high-resolution display with clear color output; and a well thought-out menu structure allow for quick changes and configuration of the device.

Six different device setups can be stored into internal memory, transforming the Digiface AES into totally different devices at the simple click of a button - especially useful in stand-alone mode. Furthermore TotalMix FX can also be controlled externally via MIDI.

Powerful Applications for Mixing, Monitoring and Measurement included

The Digiface AES also includes the powerful digital real-time mixer TotalMix FX. It allows fully independent routing and mixing of input and playback channels to all physical outputs. Independent stereo submixes plus a comprehensive Control Room section offer unrivalled monitoring capabilities and unsurpassed routing flexibility.

TotalMix Remote enhances the power of RME interfaces by enabling remote control via iOS, PC or Mac. With a straightforward set up process — simply enter the IP address of the computer you would like to control with TotalMix Remote and get going — users can quickly adjust any aspect of TotalMix FX on a host system while walking around the studio with their tablet, or from a control room located elsewhere in the facility.


Included Accessories

• USB 2.0 Cable, 1.8 m (6 ft)

• MIDI Breakout Cable

External power supply with locking connector

• Power cable


TotalMix FX & DIGICheck

The Digiface AES comes with the TotalMix FX DSP mixer offering comprehensive routing and monitoring options, as well as the DIGICheck Analyzer allowing to measure and analyze the digital data feed in both directions with maximum precision.

RME's DSP-based TotalMix FX mixer allows for fully independent routing and mixing of all 14 input and playback channels to all 16 physical outputs. Independent stereo submixes, plus a comprehensive Control Room section, offer unrivalled monitoring capabilities and unsurpassed routing flexibility.

Every input and output channel comes with a luxury feature set, comparable to that of a full-scale digital console. The effects per channel include 3-band parametric EQ (and adjustable Low Cut), MS Processing and phase reversal. The Reverb and Echo effects unit is available for all channels by a stereo send and return bus, all of which is offered even at 192 kHz operation.

Latency-Free Monitoring

The complete effects section not only adds flexibility to the recording chain , but even does away with the need for an external mixer or additional latency-inducing software. Latency-free monitor mixes can be easily created - complete with EQ and Reverb - e.g. for the main studio monitors and the headphone of the vocalist(s) in the recording room.


RME’s DIGICheck Analyzer is a free suite of professional audio analysis tools, providing users with additional measurements digital data feed in both directions with maximum precision.

The set of tools includes comprehensive multi-channel level metering (peak and RMS); a 30-Band spectrum/frequency analyser, plus correlation meter and vectorscope; a loudness metering tool for checking against the IT 1770 / EBU R128 standards commonly found in broadcast; and a Surround Audio Scope for surround sound level metering with extended correlation analysis, ITU weighting and ITU summing.

Network Control via TotalMix Remote

TotalMix Remote is a network remote control app for all RME audio interfaces and sound cards. Available as a free download via the RME website, TotalMix Remote allows for full control of the hardware mixer and effects section of the Digiface AES via a network-connected PC, Mac or Apple iPad, including wirelessly over Wi-Fi!

TotalMix Remote mirrors the current state of the host system on the iPad and Windows/Mac computers - the entire mixing state, the complete routing, all FX settings, up to the level meters, and everything in real-time.

TotalMix Remote supports up to three hosts with multiple interfaces each, allowing Apple's popular iPad and Windows/Mac computers to adjust all the mixer and FX settings from a distance, via Ethernet and Wi-Fi.

SteadyClock FS - FemtoSecond Clocking Technology

The RME Fireface UCX II also features RME's latest digital clocking and jitter rejection technology, 'SteadyClock FS'. Originally developed for RME's award-winning ADI-2 Pro FS range of high-end AD/DA converters, SteadyClock FS reduces the intrinsic jitter (when converting to and from analogue over all digital formats) to a new all-time low.

All clock modes provide excellent performance and astonishingly high-quality analogue conversion, allowing you to hear your mix exactly as it is. What's more, RME's digital format conversion occurs without any loss to the signal, and SteadyClock FS ensures your sonic image will never experience any kind of degradation. This helps to optimize recordings and mixes, ensuring the soundstage is replicated to the fullest depth and clarity.

Optional: RME ARC USB (Advanced Remote Control)

The RME Digiface AES can also integrate with RME's optional ARC USB remote control (sold separately).

When connected to a computer's USB port, the ARC USB provides users with quick access to all of the most used functions of TotalMix FX, with 15 user-definable buttons, a large encoder wheel, and a TS jack for connecting a foot switch.

The RME ARC USB is a USB 1.1 MIDI remote control - thanks to operating as a UAC 1 class device, it is natively compatible to Windows and Mac OS X. As soon as it is present in the operating system, TotalMix FX will automatically detect the ARC USB, and communicate with it via simple MIDI remote commands to control the UCX II.
