What do the PGM meters show?

The PGM (Program) meters are designed to provide a visual representation of whatever is currently being monitored within a broadcast or recording environment. They are crucial for audio engineering, allowing the operator to assess the audio levels of the mixed signals that are going out to the audience or recording device. This means the meters can indicate the output of the entire mix rather than just specific channels or fader positions.

Monitoring in this context could include live broadcasts, recorded content, or any other media where audio levels need to be consistent and correctly balanced for optimal sound quality. Therefore, the key point is that the PGM meters reflect the overall output levels that are being sent to listeners or viewers, embodying a holistic view of the program's audio state at any given time.
