Output Format
Word
The word clock output signal usually equals the current sample rate. Selecting Single Speed
causes the output signal to always stay within the range of 32 kHz to 48 kHz. So at 96 kHz and
192 kHz sample rate, the output word clock is 48 kHz.
Optical
The optical TOSLINK output can operate as ADAT or SPDIF output. The Channel Status is
fixed to Consumer state.
Note: The optical input detects the incoming format automatically.
SPDIF coax.
The coaxial SPDIF output can have the Channel Status Consumer or Professional. For further
details please refer to chapter 24.2.
Options
SPDIF In - TMS
TMS activates the transmission of Channel Status data and Track Marker information from the
SPDIF input signal.
Clock Mode
Sample Rate
Sets the currently used sample rate. Offers a central and comfortable way of configuring the
sample rate of all WDM devices to the same value, as since Vista this is no longer supported to
be done by the audio program. However, an ASIO program can still set the sample rate by it-
self.
At ongoing record/playback the selection is greyed out, so no change is possible.
Clock Source
The unit can be configured to use its own clock (Internal = Master), or one of the input signals
(Word, Optical, SPDIF coax., LTC = Slave). If the selected source isn't available, the unit will
change to the next available one (AutoSync). If none is available then the internal clock is used.
The current clock source is displayed to the right.
Pitch
More information on Pitch is available in chapter 8.2.
Input Status
Indicates for each input (Word, optical, SPDIF coax.) whether there is a valid signal (Lock, No
Lock), or if there is a valid and synchronous signal (Sync). The second row shows the sample
frequency measured by the hardware. In Clock Mode the clock reference is shown. See also
chapter 31.1.
The About tab includes information about the current driver version as well as the current firm-
ware version of the Fireface UC.
