master clock

A master clock is a precision timekeeping device that serves as the authoritative time source for a system, synchronizing all other clocks or timing mechanisms connected to it.

In buildings, a master clock sends signals to secondary clocks throughout the facility so they all display identical time.

In electronics and computing, the master clock generates the fundamental timing signal that coordinates operations across circuits or networked devices.

The studio's master clock ensures all digital audio equipment stays in perfect sync.
