Scenario 3: Creating a Synchronized “Digital Loop”
In certain scenarios, you may need to send digital signals to an external device while simultaneously receiving
signals from that device For example, if you have connected an external A/D – D/A converter or digital effects
processor to your ProFire 610, you will need to simultaneously send and receive digital audio through the
S/PDIF ports
In this case, either device (i e , the external digital device or your ProFire 610) can be configured as the clock
master while the other device must be configured as the slave device

Certain devices automatically lock to any incoming S/PDIF signal and do not give users
the option of selecting the clock source of the device. If your 3rd party device operates
this way, ProFire 610 should be configured as the clock master for proper operation.
In Figure 3 below, ProFire 610 is configured as the clock source (master) while the digital effects processor
synchronizes to the incoming S/PDIF signal.
