What is the proper clock connection between an HD Audio Interface (96 I/O, 192 i/O) and a Legacy
Interface (888|24, 882|20, etc...)?
Connect the Ext. Clock output port on the HD Audio Interface to the Slave Clock In on the Legacy peripheral. The
Legacy peripheral will switch to Slave mode once the proper clock is received from the HD Audio Interface. Always
use the Ext. Clock Out port of the same I/O to which the Legacy peripheral is attached.
If using multiple MIX-series audio interfaces chained off of a single HD Audio Interface, connect the Slave Clock Out
of the first interface to the Slave Clock In of the second interface.
