Mic Volume and Mute
The MPS 602 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). Mic level threshold, the level at which
ducking is initiated, is adjusted from 0 to 30 dB (default: 8 dB). Both are adjusted with SIS

commands (see

on page 52), or using the PCS software application (see
Using PCS
on page 41).
To adjust microphone threshold and program audio ducking levels via RS-232 or USB:
1.
Adjust program audio for nominal listening levels (see
page 17).
2.
Turn on the microphone by pressing the Mic Mute button (mute Indicator goes out).
3.
Speak into the microphone in a normal voice. The main program level drops
immediately.

If the microphone consistently cuts off the beginning of speech, or cuts out sections
of audio, adjust the threshold level (see
b.
If the program level is too high during talk-over, but is the proper level for times
where talk-over is not active, adjust the ducking level (see
ducking level in talk-over mode

Stop speaking into the microphone. The main program audio gradually (within 2 to 4
seconds) increases to the previous level. If not, increase the threshold level (see
talk-over threshold
on page 52).
