Output Format
Word – Single Speed
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, see Input Status.
SPDIF
The coaxial SPDIF output can have the Channel Status Consumer or Professional. For further
details please refer to chapter 23.2.
Options
DSP – EQ+D for Record
Switches EQ and Dynamics of all input channels into the recording path. In case Loopback has
been activated the EQ and Dynamics of the Output channel are within the recording path. See
also chapter 29.5.
SPDIF In - TMS
TMS activates the transmission of Channel Status data and Track Marker information from the
SPDIF input signal.
Word In - Termination
Checking this option terminates the word clock input internally with 75 Ohms.
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 the audio software is no
longer allowed to set the sample rate. However, an ASIO program can still set the sample rate
by itself.
During 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, SPDIF coax., Optical In). If the selected source isn't available (Input Status No Lock),
the unit will change to the next available one (this behaviour is called AutoSync). If none is
available then the internal clock is used. The current clock source is displayed as Current.
Pitch
More information on Pitch is available in chapter 8.2.
Input Status
Indicates for each input (Word, ADAT/SPDIF optical, SPDIF Coax.) whether there is a valid
signal (Lock, No Lock), or if there is a valid and synchronous signal (Sync). The third column
shows the sample frequency detected by the hardware (coarse recognition, 32 kHz, 44.1 kHz,
48 kHz etc.). In Clock Mode the clock reference is shown. See also chapter 32.1.
