31. General
The Fireface UCX II operates in two different modes: driver-based USB2 and Class Compli-
ant . The latter describes a standard that is natively supported by operating systems like Win-
dows, Mac OS X and Linux. No proprietary drivers are required, the device will be directly rec-
ognized when the CC firmware is loaded. The natively available features will be limited in com-
parison to those provided by the RME driver for the UCX II. For example there will be no hard-
ware settings, no (Total) Mix and no settings for the effects. However, on the iPad (iOS) the
UCX II can be fully controlled by the optional app
TotalMix FX for iPad .
The Class Compliant mode can be activated and deactivated directly at the unit, as long as it is
not connected to a Mac or PC: SETUP/REV, Options, Hardware/Diagnosis, CC Mode On.
Neither Windows nor Mac Class Compliant support is relevant, though, since there are dedicat-
ed and matured drivers for both OS X and Windows, which provide ALL the device's features at
lowest latencies. The main reason for implementing Class Compliant mode was to allow con-
necting the UCX II to an
Apple iPad ® !
The UCX II provides the iPad with the professional analog I/O connections it lacks. Superb mi-
crophone preamps with EQ, dynamics, even with the AutoSet feature, in addition to professional
balanced line outputs, and hi-power headphone outputs which also excel with high impedance
phones. Plus level and gain adjustments, AES and ADAT I/O, reverb, echo, zero latency moni-
toring, digitally via USB, without any limitation in quality, at up to 96 kHz and 24 bit. And of
course a Sysex-capable MIDI I/O.
DURec, the direct USB recording on USB memory stick or portable external hard drive, is also
available in Class Compliant mode. Especially in regard to recording on the iPad it is not only a
world-wide unique and extraordinary feature, it also proves to be some
thing you don’t want to
miss in real-world usage.
TotalMix FX for iPad also provides full support for the optional ARC USB, an Advanced Remote
Control specifically for the UCX II, making operation and handling of the iPad DAW even more
easy and comfortable.
