What is an On Air Sign?

An on air sign is a visual indicator that a broadcast is currently being transmitted live. The sign is typically placed outside of a recording studio or control room and is activated when a program or recording session is in progress. The sign is usually illuminated and may be accompanied by other indicators, such as a red light or a "live" graphic on a video monitor.

Where is an On Air Sign Used?

On air signs are commonly used in radio and television studios, as well as in other types of recording facilities such as podcast studios, film studios, and music production studios. They are typically located near the entrance of the studio or control room and are visible from outside the room. In addition to indicating when a program is live on air, on air signs may also be used to indicate when a studio is in use for other purposes such as recording or editing.

Famous References to the On Air Sign
