Which device compares time codes and acts like a master clock?

• A. Timecode Master
• B. Clock Manager
• C. Synchonizor
• D. Master Clock

Answer: (C)

Synchronizing multiple devices requires a single timing reference and a way to keep all time codes in lockstep. A synchronizer does exactly that: it accepts time code from a master source, continuously compares the time codes across all connected devices to detect drift or misalignment, and, when used as the master timing reference, provides a stable clock signal that other gear lock to. This dual role—verifying time code alignment and distributing a common clock—keeps playback, capture, and dubbing precisely in sync, preventing drift and timing gaps.

A timecode source or master clock alone covers part of the job but not the full need. A timecode master mainly provides the code, not necessarily a shared clock or ongoing comparison. A master clock offers timing reference but doesn’t inherently manage time code alignment between multiple devices. A synchronizer encompasses both aspects, making it the best fit for devices that must compare time codes and act as the master clock for the system.
