20. General

The OctaMic XTC is a UAC 2.0 Class Compliant device. Mac OS X has full UAC support built-

in, there is no driver installation required. Connect computer and OctaMic XTC with a USB ca-

ble. Mac OS X detects the new hardware as OctaMic XTC (serial number).

Under Mac OS X two modes are available: 8/4 channels at up to 192 kHz, and 24/24 channels

at up to 96 kHz, depending on what has been selected in Audio MIDI Setup. In both cases the

playback signal 1/2 can be copied to other outputs at the unit.

Firmware Update

The OctaMic XTC might receive improved features or bug fixes by a firmware update (currently

v47). This update will be available from the RME website, section Downloads, USB. Download

the tool, then unpack the zipped archive.

The Flash Update Tool updates the firmware of the OctaMic XTC to the latest version. Start the

Flash Update Tool. It displays the current revision of the OctaMic XTC firmware, and whether it

needs an update or not. If so, then simply press the 'Update' button. A progress bar will indicate

when the flash process is finished (Verify Ok).

After the update the OctaMic XTC needs to be reset by switching it off for a few seconds.

When the update unexpectedly fails (status: failure), the unit's Safety BIOS will be used from

the next boot on, the unit stays fully functional. The flash process should then be tried again.

is mostly done directly at the unit.

ternal, Mac OS X will set the

current sample rate.

configured for the system wide

usage. The Audio window

includes a menu to select the

sample rate. In 8/4 mode up to

192 kHz are supported, in 24/24

mode up to 96 kHz.
