19. Configuring the HDSP AES-32
19.1 Settings Dialog
Configuring the HDSP AES-32 is done via its own settings dialog. The panel 'Settings' can be
opened by clicking on the hammer icon in the dock. The mixer of the HDSP AES-32, TotalMix,
can be opened by clicking on the mixer icon in the dock.
The Hammerfall DSP’s hardware offers a number of helpful, well thought-of practical functions
and options which affect how the card operates - it can be configured to suit many different
requirements. The following is available in the 'Settings' dialog:
• Input selection
• Configuration of digital I/Os
• Synchronization behaviour
• State of input and output
• Current sample rate
Any changes performed in the
Settings dialog are applied immediately
- confirmation (e.g. by exiting
the dialog) is not required.
However, settings should not be
changed during playback or record
if it can be avoided, as this can
cause unwanted noises.
The status displays at the bottom
of the dialog box give the user
precise information about the current
status of the system, and the
status of all digital signals.
Quick Boot
All the card's settings described below are stored in a hardware memory, and are loaded immediately
after a power-on of the computer. In clock mode Master even the last used sample
rate is set. Directly after switching on the computer, a stable and predictable clock state is found
at the HDSP AES-32's outputs. This advanced technology completely eliminates disturbing
noises and clock network problems during power-up or re-boot.
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.
Clock Mode
The unit can be configured to use its internal clock source (Master), or the clock source predefined
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).
