14. Hardware Installation

• Connect the power supply to the Fireface and then to any suitable power outlet. Power-on

the Fireface with the rear power switch.

• Check the correct firmware version by a double click on the rotary encoder button. The

display PC means Windows, the display AP means Mac. The double click automatically

switches between both versions. Note: a change of state is only possible when the unit is

not connected to the computer.

• Connect computer and Fireface using the supplied USB cable.

15. Driver and Firmware

15.1 Driver Installation

After the Fireface has been connected, (see 14. Hardware Installation) install the drivers from

the RME Driver CD. The driver files are located in the folder Fireface_USB. Installation works

automatically by a double-click on the file Fireface USB.pkg.

RME recommends downloading the latest driver version from the RME website. If done, the

procedure is as follows:

A double-click onto driver_usb_mac.zip expands the archive file to Fireface USB.pkg. Instal-

lation works automatically by a double-click on this file.

During driver installation the programs Totalmix (TotalMix FX) and Fireface USB Settings or

Fireface Settings are copied to the Applications folder. They will automatically start into the

dock if a Fireface UCX is connected. A reboot of the computer is not required.

Possible reasons why a Fireface UC is not found after driver installation:

• The USB port is not active in the system (check in System Profiler, USB)

• The USB cable is not or not correctly inserted into the socket

• No power. After switching the Fireface on, at least the 7 segment display has to be lit.

15.2 Driver De-installation

In case of problems the driver files can be deleted manually by dragging them to the trash bin:

/Applications/Fireface USB Settings

/Applications/Totalmix

/System/Library/Extensions/FirefaceUSB.kext

/Users/username/Library/Preferences/de.rme-audio.TotalmixFX.plist
