SyncCheck 
SyncCheck indicates whether there is a valid signal (Lock, No Lock) for each input (Word 
clock, ADAT1, ADAT2, SPDIF), or if there is a valid and synchronous signal (Sync). The Auto-
Sync Ref display shows the input and frequency of the current sync source. 
Options 
Check Input verifies the current digital input signal against the settings in the record program. 
When de-activated a recording will always be allowed, even with non-valid input signals. Check 
Input is valid for MME only. 
SyncAlign guarantees synchronous channels when using MME multitrack software. This option 
should only be switched off in case the used software does not work correctly with SyncAlign 
activated. 
TMS activates the transmission of Channel Status data and Track Marker information of the 
SPDIF input.  
With Interleaved activated, the WDM devices can also be used as 8-channel devices (see 
chapter 9.6). 
Clock Mode 
The card 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 system will change to the 
next available one. The current clock 
source and sample rate is displayed in 
the AutoSyncRef display. 
The automatic clock selection checks 
and changes between the clock sources 
Word Clock, ADAT1, ADAT2, SPDIF, 
LTC and Video (LTC/Video when using 
the optional TCO module). 
System Clock 
Shows the current clock state of the 
Fireface 800. The system is either Mas-
ter (using its own clock) or Slave (Auto-
Sync Ref).
