Source-Connect 3.9 Pro and Pro X are compatible to connect with all 3.0 versions and up, except for some Remote Transport Sync, Q Manager and codec limitations. Source-Stream requires that both sides of the connection are on Source-Connect 3.9 and have Source-Stream enabled. Contact Support if you have connection questions.

Clock issues with certain digital audio connections

The Mac Pro computers known as ‘Nehalem’ and ‘Westmere’ do not always support correctly locking to an external clock source. This can be problematic when connecting via an optical/digital method to external hardware such as the Digi192. Please contact Support for other options.
