Inputs and Outputs

The UCX provides 36 channels of audio - 18 I/Os. All channels can be  used at the same time. Up to 8 analog and 10 digital channels can be  recorded onto 18 separate tracks. All outputs can be used for ASIO  Direct Monitoring purposes.

Available I/O (channels) with different Sample Rates:


 Sample Rate  Analog  SPDIF  ADAT  Total In/Out 
 44.1/48 kHz  8/8  2/2  8/8  18/18 
 88.2/96 kHz  8/8  2/2  4/4  14/14 
 176.4/192 kHz  8/8  2/2  2/2  12/12 

Overview Analog I/O


  • Inputs 5-8 (TRS - balanced)
  • Output 1-6 (TRS - balanced)


  • Inputs: 1/2 (2 x XLR/TRS Combo - balanced)
  • Inputs: 3/4 (2 x TRS - balanced)
  • Outputs: 7/8 - Phones (TRS - Stereo)

Analog I/O

The UCX provides 8 analog I/O in a very flexible combination:

8 Inputs. On the rear: 4 balanced TRS. On the front:  2 XLR inputs with Mic/Line preamps (65 dB Gain) and 2 Hi-Z capable TRS  Line/Instrument inputs..

8 Outputs . On the rear: 6 balanced TRS outputs. On  the front: One additional TRS stereo phones (playback channels 7/8). The  high power phones output offers high volumes even with high-impedance  headphones.

Sound Quality . Equipped with a new 2011 A/D and D/A  high-performance converter design all I/Os operate at up to 192 kHz.  The AD/DA conversion supersedes the outstanding technical specifications  of the Fireface UC/400 with an impressive 114 dBA dynamic range on both  record and playback. The advanced multi-bit converter architecture  guarantees excellent S/N and THD specs across a wide analog level range.  In the best RME tradition and product philosophy, the UCX converters  and preamps have no characteristic "sound" of their own. They neither  add nor remove anything, but capture the original signal just as it is. 

Due to its efficient jitter reduction, RME's superior SteadyClockTM finalizes the state-of-the-art AD/DA conversion, even when clocking to an external digital source.

Low Latency Converters . All analog I/Os use a low  latency converter design with impressive 14 samples for the ADC, and 7  samples for the DAC, independent of the used sample rate. These values  are about a quarter of the Fireface UC/400 (43/28), and even outperform  much more expensive devices. A technical breakthrough that reduces the  overall latency of timing critical applications, in live situations, and  in computer-based recording studios. The converter latency is so low  (0.4 ms at 48 kHz) that it can be ignored, turning analog digital  monitoring into real analog-style monitoring!

Professional Level Support . A great converter needs  to support the common studio levels for the perfect adaptation to other  analog equipment without loosing headroom. Like all other RME devices  the UCX supports the common professional studio levels: -10 dBV, +4 dBu,  Lo / HiGain. The software-controlled reference levels, realized  discretely in the analog domain, ensure highest dynamic range and  fidelity.
- Inputs 3 to 8: -10 dBV, +4 dBu and Lo Gain (adjustable in two groups - channels 3/4 and 5 to 8).
- Outputs 1 to 8: -10 dBV, +4 dBu and Hi Gain (adjustable in two groups - channels 1 to 6 and 7/8).

All outputs can be used for ASIO Direct Monitoring purposes.

Microphone/Instrument Preamps with AutoSet


Quality over quantity . The UCX provides two high-end mic and instrument preamps - built right into the front.

Like the famous UFX ones, both preamps use core technology of RME's  Micstasy. A high-end preamp for supreme sonic demands and critical  applications, like professional recordings of classical and acoustic  music. The outstanding preamp design boasts extremely low distortion,  excellent signal to noise ratio and a perfectly flat frequency response.  A premium solution for transmitting and amplifying any audio source  truly unchanged, be it high-level stage or typical studio signals, lower  level and high-impedance instruments, or dynamic, condenser and ribbon  microphones.

The digitally controlled gain of up to 65 dB, adjustable in steps of 1  dB over a range of 55 dB, is individually set for each preamp with the  encoder knob on the front or in TotalMix FX on the host computer. All  level settings are 100% reproducible and can also be adjusted using a  MIDI remote controller.

Each channel can be individually switched to 48V phantom power. LEDs  for signal, clip and activated phantom power give a complete overview on  the unit's status.

The two TRS inputs on the front will alternatively operate as Hi-Z  inputs. Directly plug in up to two guitars or other instruments - no  other hardware is required.

AutoSet . The UCX offers a unique RME feature which  was previously available only in the high-end microphone preamp Micstasy  and the UFX. Usually a limiter is used during the recording to prevent  clipping of the A/D converter stage. But analog processing would not  only spoil the excellent technical specifications of the UCX mic preamps  but also alter the original sound.

Thanks to digitally controlled gain the UCX can reduce the gain  automatically, thus providing perfect protection from overload with no  degradation of the audio signal, which does not have to pass any  additional electronic circuitry. Additionally AutoSet does not cause any  of the control noises known from usual limiters. SNR and THD stay  completely unchanged.

Example: In a recording session, the recording engineer asks the  vocalist or guitarist to sing or play a reference part and sets the UCX  preamp gain to an unusual high level (e. g. 50 dB). AutoSet will  automatically reduce the gain when the level reaches -6 dBFS. The  reduction is done in a musical way, based on the intensity and duration  of the input signal. Manual gain adjustment becomes obsolete most of the  time, but the gain can still be set manually. AutoSet can be switched  on for each of the 4 front panel mic and instrument preamp channels  individually.

Digital I/O, Word Clock & MIDI


SPDIF: The UCX provides a coaxial SPDIF I/O working at up to 192 kHz.

ADAT: One 8-channel ADAT I/O expands the UCX by 8  channels available simultaneously with the analog channels. They can be  used to connect an 8-channel AD/DA converter, a mixing console, or to  insert an effect device. The ADAT I/O supports sample rates with up to  192 kHz (S/MUX4). Using an external converter like the ADI-8 QS, the UCX  will provide 16 analog inputs and outputs, 12 with a sample rate of 96  kHz, and still 10 at 192 kHz.

SPDIF: The ADAT I/O can be used as optical SPDIF I/O, making the UCX connections even more flexible. 

Word Clock & MIDI: A word clock input and output  (BNC) with switchable termination plus two MIDI I/Os on a breakout  cable complete the I/O list and turn the Fireface UCX into a  professional audio system with universal usability.


TotalMix FX

Features/Differences to classic TotalMix:

  • New design and improved usability
  • Improved Control Room section for the main output (studio  monitors) and phones. Cue for quick listening to other outputs.  Separated monitor panel. 
  • Four mute, solo and fader groups each.
  • Switchable mono and stereo channel view
  • New channel options: Stereo Width, MS Processing, Phase L/R
  • Trim Mode: Adjusts the volume for all routed signals of a  channel. This option allows to modify the volume of all sends of a  channel simultaneously, equalling a hardware's trim functionality. 
  • Unlimited Undo and Redo
  • FX Sends and Returns: One send bus for every input/playback channel with Reverb/Echo
  • Expandable channel view for channel settings, EQ and Dynamics setup
  • Slim channel mode for selected or all channels, to save space or give a meter bridge view
  • 2-Row Mode: reduces the height of the mixer to two rows for smaller displays
  • Extended Matrix window with mono/stereo mode, Undo/Redo, display of phase and mute


The UCX provides the complete effects engine of the Fireface UFX - all effects are available at all sample rates.

The DSP-based TotalMix mixer supports fully independent routing and  mixing of all 18 input and playback channels to all 18 physical outputs.  Up to 9 totally independent stereo submixes plus a comprehensive  Control Room section offer unrivalled monitoring capabilities and  unsurpassed routing flexibility.

And there is more: TotalMix FX delivers hardware mixing/routing with lots of new features and a highly improved usability. 

Every input and output channel comes with a luxury feature set,  comparable to a full-scale digital console. The effects per channel  include 3-band parametric EQ, adjustable Low Cut, Auto Level,  Compressor, Expander, MS Processing and phase reversal. The Reverb and  Echo effects unit is available for all channels by way of a stereo send  and return bus. The UCX easily surpasses the competition by offering all  these effects even at 192 kHz operation.

Two DSPs ensure an impressive performance even in extreme  applications. As usual with RME, TotalMix is available with all channels  at all sample rates, completely unlimited. The second dedicated DSP  only renders effects, and therefore always has sufficient resources. For  example, at 48 kHz 36 EQs, 36 Low Cuts, 26 Compressors and Echo can be  activated. With activated Reverb and Echo still 36 EQs, 36 Low Cuts and  16 Compressors are available.

The FX-DSP uses automatic overload surveillance. As soon as no effect  can be added anymore the TotalMix surface will clearly signal this  condition. When changing to higher sample rates the UCX automatically  deactivates all effects that exceed the DSP's performance - the DSP will  never be overloaded. This also prevents any possible damage to  loudspeakers due to distortion.

The complete effects section not only adds a lot of flexibility to  the recording chain, but makes latency burdened software dispensable.  TotalMix can easily replace any external mixer, e. g. to create  different latency-free monitoring mixes with EQ and Reverb for the main  studio monitors and the headphone of the vocalist(s) in the recording  room.

Furthermore, the DSP hardware calculates RMS and Peak levels for all 54 level meters, so there is zero CPU load on the host.

The main functions of TotalMix can be remote controlled via MIDI with any Mackie Control compatible controller.


Monitor Controller . Optional Remote Control


Thanks to the multi-functional rotary encoder and the optional  Advanced Remote Control the UCX is not only a perfect desktop level  controller for the main monitors and phones. The integrated TotalMix FX  high-end mixer provides an impressive set of monitoring control features  for modern Mix-In-the-Box studios or live mixing sessions. Among them  Dim, source selection, monitor switching, integrated Talkback, a  flexible Cue setup, Mute and Mute FX, Mono, Speaker B switching and much  more.

Contrary to 3rd party external monitoring controllers, the built-in  UCX solution preserves the original sound, as its hardware outputs stay  directly connected to the studio monitors, avoiding another device with a  possible signal alteration in the signal path.

The flexibility of RME's DSP-driven TotalMix FX monitoring tool set  is impressive: any physical output can be assigned to the directly  knob-controlled monitor outputs (Main out, Speaker B, Phones 1, 2 ...) -  any output can be used. The functions Talkback, Listenback, Mono and  Dim will work automatically for the assigned outputs in the expected  way. Cue mixes can be sent to a predefined output, an external input can  be assigned and monitored with a simple click. Convenience for any  studio or live situation at its best.

The UCX provides an integrated connector on the back for RME's remote controls.

The optional  Advanced Remote Control (ARC) provides one big wheel dial, a button for level storage/recall, and  seven freely programmable buttons - six with LED - for nearly all  TotalMix FX functions. Just assign all frequently used TotalMix  functions to these buttons.

The remote comes with a flexible, 5 m (16 ft.) long cable.


Hammerfall-X-Core: USB & FireWire

RME is the only manufacturer that doesn't use a third party USB or  FireWire audio technology, but its own, self-developed Hammerfall Audio  Core with an outstanding performance and uncompromised pro audio  features. RME integrated the latest and most sophisticated version of  RME's bus technology, the Hammerfall-X-Core - combining both, USB 2.0 and FireWire - within one half-rack sized interface.

USB 2.0. Like other RME USB 2.0* interfaces the  Fireface UCX has been optimized for highest performance under Windows  and Mac OS. It uses a special customized firmware for each operating  system, and provides revolutionary ultra-low latencies even with  multiple channels.

* The Fireface UCX is compatible to USB 3 chipsets.

FireWire . The completely redesigned FireWire  technology of the HFX-Core provides the UCX with the same exceptional  compatibility and performance as RME's USB solution. The UCX does not  have any FireWire chip inside - the complete bus technology is  programmed into the FPGA and remains under direct control. If ever  necessary, it can be updated anytime by a simple firmware update.


Class Compliant Mode

The Fireface UCX is the first fully professional audio interface with the option to be used as Class Compliant interface. 

The Class Compliant mode is a standard that is natively supported by  operating systems like Windows, Mac OSX and Linux distributions. No  proprietary drivers are required, the device will be directly recognized  when the CC mode is activated by the button on the front panel.

The Class Compliant mode allows for connecting the UCX to any Apple iPadTM !

The iPad is not only an attractive mobile music creation and  recording platform, but a closed hard- and software system without  common driver problems and interferences from 3rd party hardware, like  graphic or network cards. It provides stability, a good realtime  performance and an easy handling. 

The UCX provides the iPad with the professional analog I/O  connections it lacks. Superb microphone preamps with EQ, dynamics, even  with the AutoSet feature, in addition to professional balanced line  outputs, and a hi-power headphone output that also excels with high  impedance headphones. Plus level and gain adjustments, SPDIF/ADAT I/O,  reverb, echo, zero latency monitoring, digitally via USB, without any  limitation in quality, at up to 96 kHz and 24 bit.

 The UCX adds another special feature: Instead of using the  jitter-prone USB clock, it works with its own internal SteadyClock. Many  USB audio devices extract clock for DA conversion from the USB data  packets, running in slave mode (adaptive mode), with comparably high  jitter values, especially since most won't offer active jitter  suppression. The UCX works in clock mode master (asynchronous mode),  both during recording and playback, thus achieving the exact same sound  quality with an iPad as under Windows and Mac OSX. 

Supported Inputs and Outputs . When connected to an  iPad, the analog mic/line input 1 works with mono apps, inputs 1 and 2  with stereo apps (both dual mono and stereo), and up to 8 inputs with  8-channel applications, like MultiTrack DAW and Music Studio. Garage Band supports all inputs, but only two at a time. Auria can record all 18 inputs simultaneously.

Playback will use analog outputs 1 and 2, or even more channels if  the app supports such operation. The UCX can optionally copy the iPad  playback channels 1/2 to outputs 7/8 and SPDIF/ADAT, for easier  monitoring. All outputs can be processed independently (volume, EQ,  dynamics, FX return).

Audio Routing and Processing . The UCX is also a  very powerful tool in CC mode, and can even be pre-configured via  TotalMix FX under Windows/Mac. Apart from the current configuration up  to 6 previously saved configurations can be loaded from the setup  memory, allowing for a quick reconfiguration without a connected host  PC/Mac.

The input signal will pass through all activated functions of the  TotalMix FX input channel, namely settings, EQ, and Dynamics, and is  then sent to the iPad. Like under Windows and Mac, the input fader  controls direct monitoring to any output. The FX send control for  echo/reverb is also active. The iPad's output signal passes through all  activated functions of the TotalMix FX hardware outputs, namely  settings, EQ, and dynamics. The third row's fader sets the output level.

Additional Features

SteadyClock . RME's unique jitter suppression  technology guarantees perfect sound quality throughout, making the  device completely independent from the quality of external clock  signals. Due to the highly efficient jitter reduction, the UCX  converters operate independently from the quality of the external clock  signal, as if they are working with internal clock all the time -  guaranteeing a pristine sound quality! 

SteadyClock allows the Fireface UCX to control the sample rate freely  on its own. The settings dialog includes a direct choice of the video  and audio world's most often used sample rates.

ICC . Intelligent Clock Control not only displays  every clock status, but will also retain the last valid input sample  rate in case of failure of the external source. Other renowned RME  technologies like SyncCheck offer a quick detection of clock problems.

DIGICheck . The UCX comes with RME's unique software  tool box for metering, testing, measuring and analyzing digital audio  streams. It provides a multi-track recorder, calculates the level meters  peak and RMS in hardware and is able to analyze and display playback  data from any software, no matter which format the software uses.*

Stand Alone Operation with Setup Recall .  Additionally internal memory allows for the permanent storage of six  different states of the unit. Therefore the Fireface UCX is able to  operate fully stand-alone, without any connected computer. In  stand-alone operation it can transform into totally different devices by  the simple click of a button. Furthermore, in this mode TotalMix FX can  also be controlled via MIDI. Application examples include: 8-channel  AD/DA converter, 4-channel mic preamp, monitor mixer, digital format  converter, analog/digital routing matrix.
