When the mouse pointer is on “Master Device” a submenu listing the hardware units (SSL
Soundscape audio cards) installed in the PC is displayed. Clicking the name of a card selects it as
the Master Device. The Master Clock mode of an SSL Soundscape audio card can only be set to
“Internal” if that card is the Master Device.
The “Master Device” should provide the Master Clock reference for all SSL Soundscape audio
cards installed in the computer and used by the SSL Soundscape Mixer software. However, it can
itself operate as a Clock Slave device, locked to a Master Clock signal provided by an external
device (e.g., a digital mixing console).
Master Clock
When the mouse pointer is on “Master Clock” a submenu is displayed for each installed SSL
Soundscape audio card. Clicking the name of a Master Clock source in a submenu selects that
Master Clock source for the corresponding card. The available Master Clock sources available are
different depending on the Soundscape hardware configuration. For instance, in the screenshot
below, Unit 1 is an SSL Soundscape Mixpander connected to an XLogic Alpha-Link MADI SX.
NOTE: Most problems encountered when transferring multi‐channel digital audio signals are
caused by incorrect routing or clock settings.
Internal
When “Internal” is selected, the Sample Rate is set by the on board Master Clock Generator of the
XLogic Alpha-Link unit. Other digital devices connected to the SSL Soundscape hardware should
be set to operate as Master Clock Slaves.
AES/EBU-A 1-2, AES/EBU-A 3-4, AES/EBU-A 5-6, AES/EBU-A 7-8
These options are available when the SSL Soundscape Mixpander is connected to an XLogic
Alpha-Link MADI SX.
