32. Operation
Activation of the Class Compliant mode
Remove USB cable from the UFX II. Press SETUP/REV. Turn encoder 1 until Options appears
in the display. Turn encoder 2 until Hardware/Diagnosis appears. Push encoder 2 several times
to select the entry CC Mode. Turn encoder 2 to activate CC mode. The UFX II reboots, after
which it will be in Class Compliant mode. The green CC state LED will light up as soon as a
USB connection is detected.
The option CC Routing offers two different routings of the playback signals. See chapter 35.
Connect the USB cable to the UFX II and the Lightning to USB adapter. Start the iPhone/iPad
and plug-in the adapter. If everything works as expected, the unit will enter CC host mode, indi-
cated by the green CC LED turning on. Audio playback will automatically be performed by the
UFX+, using analog outputs 1/2 and the phones outputs 9/10, 11/12 (with routing option Phones
activated).
Apps that support MIDI and are ready for Core MIDI will offer dialogs to select the desired UFX+
MIDI inputs and outputs.
32.1 Useful hints
If the unit is not in CC mode, the iPhone/iPad will detect an
incompatible USB device, and display a message saying
“Cannot Use Device – The connected USB device is not
supported”.
No sound: Incorrect output gain settings, see chapter 35. Note that the iPhone/iPad volume
control is inactive during USB operation.
If the unit does not enter Host mode: Remove and reconnect the Connection Kit.
Since 2016 Apple offers another version of the USB to Lightning Adapter, called Lightning to
USB 3 Camera Adapter. It has an additional Lightning port for power supply that charges the
iPhone/iPad even when used with the UFX II.
