When the “detect” light goes out, the microphone has gated noise below the
threshold level, so that you no longer hear it.
5. Speak into the microphone. The detect light illuminates when the
microphone detects your voice, or any sound above the threshold.
6. Readjust the threshold value so that the detect light just comes on when you
are not speaking, without cutting off the beginning of the first word.
7. Set the attack value depending on how quickly you want the noise gate to
open and transmit your voice. Talk into the microphone as you adjust this
value so that you can hear how adjustments affect the audio output in your
headphone. (Note that the detect light turns on when the gate opens.)
8. Set the release value based on how quickly you want the noise gate to close and
gate background noise after you stop speaking. If you talk into the
microphone as you adjust this value, you can hear how adjustments affect the
audio output in your headphone. (Note that the detect light turns off when
the gate closes.)
9. Adjust the range value to a comfortable level. At the maximum value, all noise
below the threshold is gated. At the minimum value, no noise below the
threshold is gated. Your operating environment determines the optimum
value.
10.If abrupt audio level changes occur as the noise gate opens and closes, either
reduce the Range value or activate Level/Noise Gate Smoothing by clicking
the box next to it on the Headset Options screen (see Figure 16). Activating
this feature smooths out abrupt audio level changes. Again, you can hear the
effect of Noise Gate Smoothing in your headphone.
LEVEL/NOISE GATE SMOOTHING
When you receive your beltpack, the Level/Noise Gate feature is not activated.
To activate this feature, click the box next to Level/Noise Gate Smoothing on the
Headset Options screen, as shown in Figure 16.
Figure 16: Level/noise gate smoothing
The Level/Noise Gate Smoothing feature prevents abrupt changes in volume
when you operate either the Noise Gate, or a beltpack’s volume controls.
For example, if you abruptly increase or decrease the incoming headphone
volume by turning the knob on your beltpack, the listen-level smoothing feature
prevents abrupt changes. This feature causes a slight lag in response times to
adjustments made with the beltpack’s volume knob.
The noise gate smoothing feature increases the noise gate’s attack and release
times to gradually change the overall outgoing signal.
