The most flexible interface on the market
The Fireface UFX III packs a host of powerful connections that enable seamless audio performance and recording. On the front panel, there are four high-quality XLR/TRS combo inputs, two stereo headphone jacks with +19 dBu output level, MIDI I/O, and a USB 3 port - allowing independent recording of up to 80 channels (with the DURec function). At the back of the unit are two optical ADAT I/Os, an AES/EBU I/O, eight balanced analog outputs with line level (including XLR stereo monitor outputs), another MIDI I/O, and an optical MADI interface (SC) with 64 bidirectional channels. An additional Word Clock connection is also available via BNC connectors for use as coaxial MADI input or output.
Expand your system with ease
The flagship Fireface UFX III boasts comprehensive connectivity to ensure you can integrate your interface into any recording, mixing or live situation you'll face. Expanding your analog channel capabilities, MADI is employed on the rear of the interface, enabling you to connect, route and mix channels through the digital domain for more flexibility than ever before. Multiple external MADI devices can also be connected in series.
The Fireface UFX III comes equipped with some of RME's hallmark features to further improve MADI flexibility. For instance, even when in USB 2 mode (which only supports up to 30 channels I/O), MADI I/O is still accessible through RME's integrated hardware mixer TotalMix FX. Additionally, the Word Clock I/O (BNC) can also be converted to MADI I/O (coaxial). The device even offers a specialized "split mode" that allows for the simultaneous utilization of both MADI I/Os - with 32 channels on optical and coaxial for each.
The complete mixing and monitoring solution
Included with Fireface UFX III is TotalMix FX DSP, offering comprehensive routing and monitoring options. Encompassing everything you need to balance, pan and sculpt a mix, TotalMix FX comes with EQ, dynamics processing, reverb and delay, all with latency-free monitoring in main monitors or headphone outputs! This can all be analysed with the included DIGICheck Analyzer, allowing you to measure data in both directions in real time with maximum precision. Ideal for keeping an eye on output levels to avoid clipping or for checking your frequency balance.
TotalMix Remote is an external controller designed to manage the hardware mixer and effects featured in RME audio interfaces through TotalMix FX. With TotalMix Remote, users can access and control the entire mixing console's state, routing, FX settings, level meters, and more in real time on both iPad and Windows/Mac computers. Whether at a distance or nearby, TotalMix Remote allows users to easily adjust and customize all mixer and FX settings via Ethernet and WiFi.
DC-Coupled outlets
Where other interfaces feature AC-coupled outputs, capacitors are used to filter extremely low frequencies. This can have an adverse on the output for your interface and cause unwanted artefacts in the subfrequencies. Fireface UFX III has been designed with DC-coupled outlets, allowing you to send CV or gate information to DC-enabled input devices such as synthesizers, modular equipment or other studio hardware, all without interfering with the sound quality of your outputs.
USB-3 Class Compliant Performance
The Fireface UFX III is equipped with two distinct modes of operation to suit different needs: driver-based USB 3 and Class Compliant. As a widely adopted standard natively supported by popular operating systems like those from Windows, Mac OSX, and Linux distributions, Class Compliant mode requires no proprietary drivers and can be directly recognized once the CC firmware is loaded. This makes for a seamless integration experience without any additional installations or downloads required.
What's more, the Fireface UFX III stands out as RME's first audio interface with full USB 3.0 support in Class Compliant mode. This unlocks access to all channels for driverless operation on Linux, Mac, and even iPadOS when connected to an iPad Pro via USB C. With recording and playback capabilities of up to 94 channels through TotalMix FX for iPad and system-level access, the Fireface UFX III provides musicians and producers with unparalleled flexibility and functionality. Choose the Fireface UFX III for a hassle-free experience and exceptional performance in Class Compliant mode.
Direct USB Recording with DURec
Integrated into all inputs and outputs, Fireface UFC III enables the user to record directly to a thumb drive or hard drive via the onboard front-mounted USB port. Independent from your computer, the internal processing powers the data transfer to ensure the highest-speed transfers with immaculate stability to ensure your files are not tarnished. Transforming your interface into a dedicated recording device, DURec USB recording is perfect for live recordings on stage or for recording rehearsals or jam sessions.
