Which term refers to a device that compares time codes and acts like a master clock?

• A. Time Master
• B. Timecode Comparator
• C. Synchronizer
• D. Synchonizor

Answer: (D)

The device that compares time codes and acts as the master clock is called a synchronizer. It keeps all timing devices in step by monitoring the time codes from the source and then distributing a single, stable timing reference so every piece of gear follows the same tempo. This ensures that video and audio stay perfectly aligned across equipment, which is crucial in multi-device setups.

A timecode comparator would only check that time codes match, but wouldn’t by itself assume the master timing role or drive other devices. The term Time Master isn’t a standard label for this function, and Synchonizor isn’t a recognized device name (and is a misspelling). So the natural term that captures both comparing codes and providing the master clock reference is synchronizer.
