When you set the threshold value to “minimum,” the gate opens when it detects
low-level sounds, and all sounds above that level transmit through the
microphone to the intercom line. When you set the value to “maximum,” only
very loud sounds open the gate, and only sounds above that level transmit
through the microphone to the intercom line.
When you set the value at any midpoint on the scale, only the sounds above that
midpoint transmit through the microphone to the intercom line.
Note: In most situations, you set the threshold so that the noise gate closes to block out
as much background noise below the level of your speech as possible.

The “detect” light illuminates when the audio level in the beltpack’s microphone
goes above the set threshold. This light appears just below the noise gate settings
on the screen. Using this light helps you to set the threshold to the appropriate
value.
In practice, you usually set the threshold at the level of your voice speaking into
the microphone, so that the microphone only transmits when it detects your
voice, and gates out all or most background noise. To do this, speak into the
beltpack’s microphone, and adjust the threshold value so that the detect light just
goes out when you are not speaking. For more detailed instructions on setting
this value, see “Setting the Noise Gate Values” on pages 5-10 and 5-11.
Experiment with the threshold value to get the best balance between voice level
and background noise level.
A TTACK
Attack determines how quickly the noise gate opens when you start speaking.
Moving the slider down on the scale causes the noise gate to open more quickly.
Moving the slider up on the scale causes the noise gate to open more slowly.
Adjusting this value affects how quickly the microphone picks up and transmits
the sound of your voice, resulting in less choppy background noises, especially if
other beltpack users are using noise gates on the same channel.
Adjust this value so that the noise gate opens early enough not to cut off words at
the beginning of sentences.
R ELEASE
Release determines how quickly the noise gate closes when you stop speaking.
Moving the slider up on the scale causes the noise gate to close more slowly.
Moving the slider down on the scale causes the noise gate to close more quickly.
Adjust this value so that the noise gate doesn’t close too early and cut off words at
the end of sentences.
R ANGE
Range determines to what extent the gate closes to block out the signal. Since the
noise gate “closes” when you stop speaking, the sounds filtered out are
background noises.
