33. Operation
Activation of the Class Compliant mode is done in two ways.
Via TotalMix FX
: The interface is connected to Mac or PC and can be controlled by TotalMix
FX. Check the entry Activate CC mode on disconnect in TotalMix FX Options. As soon as the
connection to the computer is interrupted, the Fireface 802 boots into Class Compliant mode.
Upon reconnection to the computer the CC mode is automatically disabled.
Note: When the computer enters standby mode (sleep) the interface will not change to CC
mode, as there is no disconnection – just a temporary one until the computer is switched back
on.
Via Advanced Remote Control*
: Remove FireWire and USB cable from the 802, turn off the
unit. Connect the ARC, push and hold keys Prog and A (Talkback), then turn on the 802. The
unit boots into CC mode. With the keys Prog and B (Mono) the 802 boots into normal mode.
Connect the USB cable to the 802 and the Camera Connection Kit. Start the iPad/iPhone and
connect the Camera Connection Kit. If everything works as expected, the unit will enter CC host
mode, indicated by the blue USB LED turning on. Audio playback in iTunes will automatically be
performed by the 802, using analog outputs 1/2.
Apps that support MIDI and are ready for Core MIDI (available since iOS 4.2) will offer dialogs
to select the desired 802 MIDI inputs and outputs.
33.1 Useful hints
If the unit is not in CC mode, the 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 or wrong routing, see chapter 34. Please note that the
iPad/iPhone 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 Fireface 802.
