Scenario 2: ProFire 2626 Slaved to an Optical Input
If you prefer to use another device as clock master, you will need to configure that device to act as master and select
that device’s input on ProFire 2626 as the sync source. This locks (or “slaves”) ProFire 2626 (and any other devices
connected to ProFire 2626) to that master device.
In Figure 2 below, a digital multi-track recorder with an ADAT optical output is configured as clock master. ProFire 2626
and other devices (a DAT machine and another multi-track recorder, in this case) receive and lock to the clock of the
“master” ADAT device.
