Audio Master Clocks Fundamentals and Application Notes — Part 2

What devices need clocking?
 
In a simple system featuring one audio interface with built-in mic preamps connected to a computer-based DAW, the interface clocks the DAW since the most clock-critical element of the audio chain is the A/D converter, as that’s built in to the interface. If you were to add an external digital device to the equation (reverb, multi-effects processor etc), it should be configured to work as a clock slave to the interface.
 
Following that logic, even in bigger and more complex studios, it’s generally best to use an A/D as the master clock. If there’s more than one of these you’ll need to decide which one to use as the master, and everything else will have to be slaved to that. It’s quite possible that there will be audible differences between various configurations, because most A/Ds will perform slightly differently when configured as clock master and slave.

Antelope Audio Isochrone OCX Master Clock Helps Ensure System Clarity During Austin Music Festival
