SPDIF In
Defines the input for the
SPDIF signal. 'Coaxial'
relates to the RCA socket,
'ADAT1' to the optical
TOSLINK input.
SPDIF Out
The SPDIF output signal is
constantly available at the
phono plug. After selecting
'ADAT1' it is also routed to
the optical TOSLINK out-
put. For further details
about the settings ‘Profes-
sional’, ‘Emphasis’ and
‘Non-Audio’, please refer to
chapter 26.2.
SPDIF Freq.
Displays the sample rate of
the signal at the SPDIF
input.
I/O Box
Disconnect interrupts the communication between I/O-box and PCI or CardBus card. In case
the Digiface has been configured using the Settings dialog and TotalMix, Disconnect allows to
use it Stand-Alone (without a connected computer), after a power supply has been attached.
The status display below shows the current state of the I/O-boxt:
Error: I/O-box not connected or missing power
Detected: The interface has found an I/O-box and tries to load the firmware
Connected: Communication between interface and I/O-box operates correctly
Disconnected: Communication between interface and I/O-box has been interrupted, I/O-
box continues operation
Clock Mode
The unit can be configured to use its internal clock source (Master), or the clock source pre-
defined via Pref. Sync Ref (AutoSync).
Pref Sync Ref
Used to pre-select the desired clock source. If the selected source isn't available, the unit will
change to the next available one. The current clock source and sample rate is displayed in the
AutoSync Ref display.
The automatic clock selection checks and changes between the clock sources Word Clock,
ADAT optical, ADAT Sync and SPDIF.
Word Clock Out
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
sample rate, the output word clock is 48 kHz.
Time Code
Time Code from the input ADAT Sync. Not available for the Digiface under OS X.
