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 and
192 kHz sample rate, the output word clock is 48 kHz.
Buffer Size
The setting Buffer Size determines the
latency between incoming and outgo-
ing ASIO and GSIF data, as well as
affecting system stability (see chapter
13/14).
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).
System Clock
Shows the current clock state of the
HDSP system. The system is either
Master (using its own clock) or Slave
(see Pref. Sync Ref).
Output Format
Double Speed: Sample rates in the
range of 64 kHz to 96 kHz can also be
transmitted using the standard 48K
frame. Note that when selecting
Double Wire the number of output
channels is reduced to 8.
Quad Speed: Sample rates in the range of 128 kHz to 192 kHz can also be transmitted using
either the standard 48K frame, or the 96K frame. Note that when selecting Double Wire the
number of output channels is reduced to 8. When selecting Quad Wire the number of remaining
output channels is 4.
For further details about the settings 'Professional', 'Emphasis' and 'Non-Audio', please refer to
chapter 22.2.
Input Status
SyncCheck indicates whether there is a valid signal (Lock) for the inputs Word Clock and AES 1
to 8, or if there is a valid and synchronous signal (Sync). The System Clock Mode display
shows the input and frequency of the current sync source. Each input has its own frequency
measurement and display of the input signal's current sample rate.
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
System Clock field.
About
This tab includes information about the driver and the card's firmware version.
Lock Registry uses a password to prevent changes of the settings stored in the registry. All
settings are still changeable temporarily. As the settings are always loaded from the registry
when starting the computer, this method provides an easy way to define a specific initial state of
the HDSP system.
