35. Front panel operation
The front panel operation is identical to the one under Windows and OS X, or standalone opera-
tion. The display therefore gives the usual easy access to all features and offers a quick editing
of: input gains, playback levels, routing and monitoring, echo, reverb, EQ, dynamics, sample
rate, status of the optical output (ADAT/SPDIF), and much more.
36. Audio Routing and Processing
In Class Compliant mode, the UCX II features operation very similar to normal operation with
TotalMix FX, with two major differences:
 There is no second TotalMix row (no software playback channels), hence no individual
routing or mixing of playback channels (unless the optional app TotalMix FX for iPad is used).
These will always be connected either straight to the physical outputs (CC Mix 20 Ch.), or
have an additional signal copy, see below.
 The input effects EQ/Dyn will always be active in the recording path
The UCX II can be pre-configured for CC mode via TotalMix FX under Windows/Mac by saving
up to 6 configurations into its setup memory, see next chapter.
The input signal will pass through all activated functions of the TM FX input channel, namely
settings, EQ, and Dynamics, and is then sent to the iPhone/iPad. Like under Windows and Mac,
the input fader setting controls direct monitoring to the specified outputs. The FX send control for
echo/reverb is also active.
As in normal TotalMix FX use, the options Stereo Width, MS Proc and Phase L/R are NOT
within the recording path, but in the monitor path. This is technically determined and can not
be changed.
The iPhone/iPad output signal passes through all activated functions of the TM FX hardware
outputs, namely settings, EQ, and dynamics. Configuring the Phones output is done by output
channels 7/8.
CC Mix Modes
The CC Mix modes can be activated at any time and do not influence the mixer state loaded via
the Setups, as Mix modes only influence the playback routing. The current routing can easily be
checked and verified with the level meter display.
The unit offers four different
Mix modes to ease using the CC mode without TotalMix FX for
iPad . They copy playback signals to various channels.
TotalMix App . Locks various settings in several menus to avoid conflicts with TotalMix FX for
iPad , in case the app is not in background mode. Note that all copy modes are automatically
disabled when the TotalMix app is detected.
8 Ch. + Phones. 8 channels of playback. Channels 1/2 are copied to Phones, SPDIF and ADAT
1/2. Channels 3/4 are copied to AES and ADAT 3/4, channels 5/6 and 7/8 to ADAT 5/6 and 7/8.
8 Ch. Playback . Same, but no copy of 1/2 to Phones, so the output Phones (7/8) is available for
separate playback.
20 Ch. Playback. No copy mode active, all 20 channels are available separately.
