MME
Check Input verifies the current input signal against the settings in the record program. When
de-activated a recording will always be allowed, even with non-valid input signals.
TMS activates the transmission of Channel Status data and Track Marker information of the
SPDIF input. Check Input is valid for MME only.
Buffer Size
The setting Buffer Size determines the latency between incoming and outgoing ASIO and GSIF
data, as well as affecting system stability (see chapter 13). Under Windows MME this setting
determines the DMA buffer size (see chapter 8.5).
SyncCheck
'SyncCheck' indicates for
ADAT, SPDIF and word
clock input whether there
is a valid signal ('Lock' or
'No Lock'), or a valid and
synchronous signal
('Sync'). The 'AutoSync
Ref' display shows the
input and frequency of
the current sync source.
SPDIF In
Defines the input for the
SPDIF signal. 'Coaxial'
relates to the phono
socket, 'Optical' to the
optical TOSLINK input,
Internal to the jumper
CD/SYNC IN/AEB IN,
AES to the optional XLR
cable.
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 settings 'Professional',
'Emphasis' and 'Non-Audio', please refer to chapter 12.
Clock Mode
The card can be configured to use its internal clock (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 card will
change to the next available one. The currently used clock source and sample rate is displayed
in the AutoSyncRef display.
The automatic clock selection checks and changes between the clock sources ADAT optical,
SPDIF and word clock.
System Clock
Shows the current clock state of the HDSP system. The system is either Master (using its own
clock) or Slave (AutoSync Ref).
