Clock Mode
Word Clock – 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.
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, AES, ADAT1,
ADAT2). If the selected source isn't
available (Input Status No Lock), 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.
Input Status
Indicates for each input (Word, AES,
ADAT1, ADAT2) 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 hard-
ware (coarse recognition, 32 kHz, 44.1
kHz, 48 kHz etc.).
