MICROPHONE NOISE GATE
The RS-600 Series are the first beltpacks to offer an onboard full-function
Microphone Noise Gate. The Microphone Noise Gate allows you to restrict or
“gate” background noise at the beltpack’s microphone, so that it does not
transmit to the intercom line.
With Noise Gate activated, the beltpack microphone operates as a very flexible
voice-operated switch, which only transmits sound when it detects your voice.
When you stop speaking, the switch shuts off, preventing external background
noise from reaching the intercom line.
Four parameters determine how the gate operates: Range, Threshold, Attack, and
Release. Each parameter is on a scale ranging from a maximum setting to a
minimum setting, as shown in Figure 13. To select a relative value on the scale,
move the slider to the appropriate place on the scale.

As you set the values for the four parameters, you can hear the audio change in
your headphone if your beltpack is connected to the computer and online.
Because all of the noise gate settings work together, adjusting the noise gate in a
live setting works best.
If it is not practical to set the noise gate values in a live setting, you can
experiment with settings by preprogramming a different group of noise gate
settings into each Mode on a beltpack. You can try different range, threshold,
attack, and release settings for each Mode, and see which Mode works best in
your particular environment.
T HRESHOLD
Threshold sets the audio level at which the gate opens and closes. Typically you
set the threshold value at the level of your voice, so that when you speak into the
beltpack’s microphone, the noise gate switch opens to allow audio onto the
intercom line, and when you stop speaking, the gate closes so that no audio
transmits to the intercom line.
