Operating Basics
The Microphone Setup allows you to optimize the microphone input
settings for your particular configuration. Choose Standard Microphone if
you have an ordinary desktop microphone. Choose Headset if you have a
wearable microphone that is positioned directly in front of your mouth.
You can launch the Setup Wizard from the Control Panel to help you to
automatically set proper microphone input volumes and ensure that your
voice input(s) are working correctly. As you speak into the microphone, the
Sound Meter indicates the audio signal that your computer is receiving.
The Noise Reduction enhancement helps to eliminate ambient noise from
the voice input signal to provide a clean and clear signal to applications.
This feature can be used with any microphone.
The audio controller can be powered down when the audio function is idle.
To enable the Audio Power Management, follow the steps below.
1. Click the Power Management tab.
2. Select the Normal Power Savings in the Power Mode pull-down list.

Region selection
Telecommunication regulations vary from one region to another, so you will
need to make sure the internal modem’s settings are correct for the region
in which it will be used.
If the No Power Savings is selected, the audio controller always runs.
