The previous three examples have covered some of the most common clocking methods and are intended to help you
understand the basic principles of digital clocking. Note that there are many other ways in which proper clocking can
be established between digital audio devices and this chapter cannot cover every conceivable scenario. If your studio
uses more advanced clocking devices such as a "house" master clock, please refer to that device's user guide to learn
more about how it can be configured to work with ProFire 2626.
