Talk-over Control Using PCS
The MPS 602 also features talk-over to automatically reduce program audio volume
when microphone audio is present. When the switcher detects an audio signal from the
Mic input, it immediately reduces or "ducks" the program audio volume. When microphone
audio is not detected for a period of one second, it increases the program audio level at a
rate of 3 dB per second until the program audio returns to the original volume level.
Ducking is adjustable from 0 to 30 dB (default: 6 dB) and Mic level threshold, the level at
which ducking is initiated, is adjusted from 0 to 30 dB (default: 8 dB).
To adjust microphone threshold and program audio ducking levels using the PCS software
