What does a normal moving audio level meter indicate if the air monitor speaker falls silent?

A normal moving audio level meter reflects the signal levels of audio being processed, which indicates that audio content is present and functioning as intended. Therefore, if the air monitor speaker falls silent but the audio level meter is still moving, it suggests that there is still potential audio content being transmitted, and listeners may still be hearing programming that is not being output through the monitor speaker.

This situation could arise from various factors including issues with the monitor speaker itself, but it does not imply that the overall transmission of programming has stopped. Even though the listeners may not hear anything through the monitor, the content could still be reaching the audience through other means, such as radio transmission where the audio level shows activity.

If the transmitter were off, or the programming had truly ended, the audio level meter would also drop to silence, indicating no audio is being transmitted. Additionally, stating that your equipment is malfunctioning would imply a broader and more serious issue, rather than just a problem with monitoring. Thus, B is the most accurate interpretation of the situation.
