First, we need to make sure that your Snowball is properly plugged into the computer. It is advised to use the USBs on the computer itself rather than a splitter or dock of some kind. If this is not possible because of the computers location or all the USBs are populated, you can still use your dock or USB hub. This is only a recommendation.

Your Snowball microphone has three settings that can be changed with a single switch on the back. this is shown in the image below.

1. The first setting is a directional mode for when you want to talk directly into the microphone. This helps reduce noise coming from the sides and the back of the Snowball.
2. The second setting will reduce the volume of the audio going into the Snowball. This does not change any other setting.
3. The Third setting will set the Snowball into more of an omnidirectional mode. This means that it will pick up more sound around the sides and back of the Snowball and is recommended for live and recorded class sessions where the professor is not directly in front of the microphone. It is still recommended to point the Snowball in the general direction of what you want to pick up such as the rest of the classroom because the Snowball can still struggle to pick up sound directly from the behind.
    

Make sure you set your microphone settings on the computer to use the Snowball rather than the default microphone in the webcam. This can be achieved by right clicking the sound icon on the bottom right of your taskbar and choosing 'open sound settings'. 

Navigate to the input section of your sound settings and make sure the Snowball has been selected and make sure that the volume is most of the way up. This is shown in the images below.

If possible, please review your recordings and live stream sessions to make sure that your voice and the rest of the class is clearly audible for your remote students.
