Output Options
SPDIF Format
The SPDIF coaxial output signal can have the Channel Status Professional or Consumer. For
further details please refer to chapter 21.3.
Optical Out
The optical TOSLINK output can operate as ADAT or SPDIF output.
Clock Options
Word Clock I/O
– Single Speed
The word clock output signal usu-
ally equals the current sample
rate. Selecting
Single Speed caus-
es 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.
The word clock input usually
adapts to the current sample rate
range. For example a 48 kHz word
signal can be used to sync the
internal clock of 96 and 192 kHz.
When the option
Single Speed is
not checked the interface’s sam-
ple rate follows the external sam-
ple rate directly. A word signal of
192 kHz will cause the UCX II to
use 192 kHz internally. This fea-
ture is also called
Follow Clock .
Sample Rate
Used to set the current sample
rate. This is the same setting as in
the Audio MIDI Setup, just added
here for your convenience.
Clock Source
The unit can be configured to use its own clock (Internal = Master), or one of the input signals
(Word, SPDIF, AES, ADAT). 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 below.
Input Status
Indicates for inputs Word, SPDIF, AES and ADAT whether a valid signal (Lock, No Lock) or a
valid
and synchronous signal (Sync) is present. The third column shows the sample frequency
detected by the hardware (coarse recognition, 32 kHz, 44.1 kHz, 48 kHz etc.).
Short Safety Offset
Reduces overall latency by using smaller Safety Offsets (12 samples instead of 24 samples).
Change is performed in real-time. Smaller Safety Offsets might cause clicks and dropouts.
