The most powerful & portable RME Audio USB Interface

Whether working in your home recording studio or bouncing around different gig venues, the Fireface UCX II is an incredibly portable interface. At only 2 lbs and no wider than 8.5", the modular design of the Fireface UCX II makes it easy to travel with, taking up minimal space within your audio system setup. The Fireface UCX II houses two microphone preamp/line preamps in XLR combo configuration on the front panel, along with two digitally controlled line/instrument inputs, followed by a headphone jack, various control buttons, a display, and the main volume knob. At the rear are a set of ten analog balanced line inputs and outputs— MIDI I/O, ADAT I/O, AES/EBU—and SPDIF I/O, USB 2.0 as well as a switchable word clock I/O.

This unique audio system is capable of transferring analog and digital audio data directly to Windows and Mac computers. The latest plug-and-play technology, RME USB allows you to transport audio with the lowest latency and industry-leading stability. Numerous unique features like a well-thought-out Settings dialog and an integrated routing solution realize a quick, comfortable, and efficient operation of the Fireface UCX II.

Full Stand-alone Functionality

Control all device states directly from the front panel of the Fireface UCX II for convenient, direct access to all features. Use the four keys, high-resolution clear color display, and well-thought-out menu structure to quickly change and configure the device's settings. Additionally, internal memory allows for the permanent storage of six different states of the unit, allowing the Fireface UCX II to operate fully stand-alone. In stand-alone operation it can transform into totally different devices by the simple click of a button.

The Fireface UCX II operates in two different modes: driver-based USB2 and Class Compliant. The Class Compliant Mode is a standard that's used natively, supported by operating systems like Windows, Mac OSX, and Linux Distributions. No proprietary drivers are required to use this mode as the device will be directly recognized when the CC firmware is loaded. Note: The natively available features will be limited in comparison to those provided by the RME driver for the Fireface UCX II.

Powerful Technology for Mixing, Monitoring and Measurement included

The RME Fireface UCX II comes with the TotalMix FX DSP mixer offering comprehensive routing and monitoring options. 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, including main monitors and headphone mixes for musicians. The additional TotalMix Remote is a remote control for TotalMix FX, controlling the hardware mixer and effects in RME audio interfaces. The 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. Easily adjust all the mixer and FX settings from a distance, via Ethernet and WiFi.

The Fireface UCX II is also equipped with DigiCheck, RME's secret weapon of high-resolution audio measurements. The DigiCheck Analyzer allows you to measure and analyze the digital data feed in both directions with maximum precision. SteadyClock FS is RME's reference-class digital clocking technology that suppresses jitter guaranteeing perfect sound quality throughout your entire mixing process.

DURec is an integrated digital recorder that allows you to record on USB thumb drives and hard drives with up to 2TB capacity via the rear USB port. The recording functionality is provided by the internal DSP, and is therefore independent from a connected Windows or Mac computer. This USB port can alternatively be used for direct connection of RME’s optional ARC USB remote control.

DC-Coupled Outputs - CV/Gate Voltage Control

The RME Fireface UCX II stands out from other audio interfaces due to its unique DC-coupled outputs. While most interfaces traditionally use AC-coupled outputs with capacitors to filter out extremely low frequencies, the Fireface UCX II takes a different approach.

While the low frequencies associated with AC-coupled outputs are often undesirable for audio—eating into headroom and potentially causing damage to other equipment—one instance where DC-coupling remains desirable is the world of modular synthesizers, where static or slow-moving signals are used for control over various parameters such as pitch note values or LFOs.

All of the Fireface UCX II line-level outputs are fully DC-coupled, allowing control voltages (CV) or Gate information to be sent to modular synthesizers (such as the popular Eurorack and Moog/MOTM/Synthesizers formats) and other studio hardware. By offering DC-coupled outputs, the RME Fireface UCX II enables a more versatile and integrated approach to working with modular synthesizers and studio equipment, making it an ideal choice for electronic musicians and producers who require this level of connectivity and control.
