5.2 Quick Start
 
After the driver installation (chapter 6 / 13) connect the TRS jacks or the XLR inputs with the 
analog signal source. The input sensitivity of the rear inputs can be changed in TotalMix (Input 
Channel Settings, +13 dBu / +19 dBu and Gain), assuring the highest signal to noise ratio will be 
achieved. Also try to achieve an optimum input level by adjusting the source itself. Raise the 
source’s output level until the peak level meters in TotalMix reach about –3 dB. 
 
The signal level of the front inputs can also be optimized directly at 
the Fireface. The key MIC/GAIN gives direct access to this setting, 
which is then controlled by the encoder VALUE. 
 
The digital outputs of the Fireface UCX II provide AES/EBU, SPDIF 
coaxial, SPDIF optical and ADAT optical at the respective ports. 
 
On the analog playback side (the DA side), a coarse adjustment of 
the analog output level at the rear jacks is again available in TotalMix 
(Output Channel Settings, Level), or the Channel Settings directly at 
the device. The big encoder VALUE controls the Main Out volume 
(default: Line Out 1/2). 
 
The output signal of channels 7/8, Phones, can also be controlled 
directly from the VALUE encoder. 
 
 
The Fireface UCX II can store and load its current state in 6 different 
memory slots, called Setups (SETUP/REV, Options, Load/Store all 
Settings). With this, the Fireface UCX II can be used stand-alone 
after setting it up accordingly, replacing lots of dedicated devices (see 
chapter 24). 
 
 
In online mode some settings are greyed out, as these should be changed only at the computer, 
in the Settings dialog or in TotalMix FX. These include the choice of sample rate and the mix 
settings. 
 
 
5.3 Menu and Navigation
 
The Fireface UCX II has a simple and clear menu structure, for fast and efficient operation di-
rectly at the device. In most cases, however, all settings will be done via the Settings dialog and 
TotalMix FX of the host computer. The operation on the device is typically limited to a direct 
adjustment of the monitoring volume (loudspeaker and headphones), the microphone gain, and 
DURec (Direct USB Recording). In stand-alone mode, all settings are available directly on the 
device. 
 
Navigation through the menus of the display and control of the settings is done via four quick 
select buttons and a rotary encoder with push function. 
 
Default in the display is the Global Level Meter screen, which shows the current signal levels for 
all I/Os. By pressing the encoder knob VALUE for half a second, only the analog I/Os (Analog 
Level Meter screen) are displayed, which makes the level display larger and thus easier to read.
