RME Audio DSP System Multiface User Manual page 14

Clock Source
The unit can be configured to use its own clock (Internal = Master), or one of the input signals
(Word, SPDIF, ADAT). 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.
SPDIF In
Defines the input for the SPDIF signal. 'Optical' relates to the optical TOSLINK input, 'Coaxial' to
the RCA socket. TMS activates the transmission of Channel Status data and Track Marker in-
formation. In case these information are not required the feature should be turned off. The Sam-
ple Rate of the incoming SPDIF signal is displayed as well.
SPDIF Out
The SPDIF output signal is constantly available at the phono plug. After selecting 'Optical' it is
also routed to the optical TOSLINK output. For further details about the setting 'Professional',
'Emphasis' and 'Non-Audio' please refer to chapter 23.2.
SyncCheck
Indicates whether there is a valid signal (Lock, No Lock) for each input (ADAT, SPDIF, Word
Clock), or if there is a valid and synchronous signal (Sync).
Word Clock
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.
I/O Box
Disconnect interrupts the communication between I/O-box and card. In case the Multiface 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.
I/O Box State
This field displays the current state of the I/O-box.
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
Time Code
Time Code from the input ADAT Sync. Not available for the Multiface II.
The tab About includes two more, global options:
Lock registry
Default: off. Checking this option brings up a dialog to enter a password. Changes in the Set-
tings dialog are no longer written to the registry. As the settings are always loaded from the
registry when starting the computer, this method provides an easy way to define an initial state
of the HDSPe AES.
Optimize Multi-client Mixing
Default: on. Unchecking this option might solve compatibility problems in seldom cases, but will
also introduce short noise burst when multi-client playback starts.
