Numerous unique features, well thought-out configuration dialogs, an industry-leading mixing engine and monitoring solution, professional DSP effects and class-leading analog circuits with latest digital converters put the Fireface UFX II at the very top of the range of computer-based audio interfaces.

Features

With exceptional flexibility and compatibility, the inclusion of DURec (Direct USB Recording), and RME’s famous low latency hardware and driver designs, the Fireface UFX II delivers a rich feature set that will appeal to users in both high end home studios and commercial audio production facilities.

With capacity for 60 audio channels (30 input and 30 output), support for sampling frequencies upward of 192 kHz, and the flexibility provided by USB connectivity, the new Fireface UFX II is an ideal solution to a wide range of recording, mixing, and monitoring applications.

The Fireface UFX II offers excellent flexibility that enables the interface to fit seamlessly into a myriad of production environments. Analog, ADAT, AES, SPDIF, and USB 2 are all standard on the Fireface UFX II. Equally impressive is the unit’s channel count: 12 analog, 16 ADAT, and 2 AES for 30 channels input and 30 channels output. Further, with support for USB 2 connectivity, the new Fireface UFX II can integrate with RME’s optional ARC USB remote controller.

RME’s Fireface UFX II incorporates premium AD/DA converters, optimized analog I/O circuits, as well as improved SNR and THD values to guarantee pristine, crystal clear and transparent audio. A new PAD-free mic circuit design with +18 dBu maximum input level and 75 dB gain range provides trouble-free operation for the most demanding recording environments.

Further, new low impedance, high power phones outputs (2 Ohms) with +19 dBu maximum output level provide ample output power and volume on any headphones - high or low impedance.

Improved DURec (Direct USB Recording)

The Fireface UFX II also includes DURec (Direct USB Recording), which is available on the front of the interface. It now offers second generation hardware with improved USB functionality and compatibility - providing greater reliability, even with slower or multi-partitioned USB thumb drives.

ARC USB Remote Control - Plug’n Play Plus

The ARC USB connects to your computer via USB, and talks to TotalMix FX directly. It has 15 freely assignable and illuminated buttons, one encoder wheel, and a TS jack to connect a foot switch.

The ARC USB is a USB 1.1 MIDI remote control for the Fireface UFX II. 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, TotaIMix FX will automatically detect the ARC USB, and communicate with it via simple MIDI remote commands to control the UFX II.

TotalMix FX

Since 2001, TotalMix has added unlimited routing and mixing to RME audio interfaces. Its unique capability to create as many independent submixes as output channels available, turned it into the most flexible and powerful mixer of its kind.

With supported hardware, TotalMix FX includes a complete effects system, which not only adds flexibility to the recording chain, but also makes latency saddled software solutions obsolete.

TotalMix FX can completely replace an external mixer, enabling the creation of multiple latency-free monitor mixes with EQ, Dynamics, Reverb and Delay for any outputs, incl. main monitors and headphone mixes for musicians.

TotalMix FX for iPad™ App

TotalMix FX for iPad™ adds full control over hardware mixer and DSP effects for Fireface UFX+, UFX II, UFX, UCX, 802, Babyface, Babyface Pro and MADIface Pro when in Class Compliant Mode, and lets you create, store and load complete mixes directly from the iPad™
