The first time you use the Start Mic Cam feature, you will be presented with some setup wizards that will help you properly setup your camera and microphone. The Microphone Settings Wizard is detailed below:

Note: When prompted by Adobe Flash Player Settings, you will need to "Allow" access to your microphone in order to broadcast via VoIP.

1) The first step in properly setting up your microphone is to make sure that it’s plugged in and that no other software applications are using it.

2) The next step would be to determine if you will be using a headset to broadcast your audio.

3) Now it's time to test your speakers. This is especially necessary if you plan on passing the broadcasting rights to anyone else during your webinar. 

If you have a USB headset or built in microphone, then you will want to look for a USB device entry or for the name of the headset you are using.

5) Finally, you will want to adjust the volume settings for your microphone to ensure that you are providing the best audio experience for your attendees. The volume level will provide a graphical representation of your current volume as you speak into your microphone. Generally, you will want to adjust your volume so that you occasionally see a little yellow when you are making a strong point, without reaching red.
