Connect and Adjust Your Headset


These instructions are based on typical Windows PC components. Your exact equipment may vary.


In order to use the two-way audio features in Wimba, it is recommended that you use a headset with both headphones and a microphone, which should look something like the headset shown. This document explains how to connect your headset to your PC computer.


Headsets are available from the Academic Technology Center (ATC) for a small fee. WPI community members can purchase a headset by visiting the ATC in Fuller Labs 117 or contacting the ATC at 508-831-5220 or


You can also use a phone connection (long distance charges do apply) or speakers and a microphone which are built into some laptop computers or external speakers and an external microphone, but the sound is often better when a headset is used. The ATC has external microphones available for check out from the equipment inventory.

Identifying Headset Plugs

Your headset has two plugs at the end, one for the microphone and one for the headphones. They might look like the following:

The headphones plug (1) can be identified by one of the following characteristics:

The microphone plug (2) can be identified by one or more of the following characteristics:

Once you know which plug is which you can find the matching jacks on your computer to plug them in.

Identifying Computer Jacks

The jacks on your computer are typically located on the back of your desktop computer or on the side of a laptop computer. Newer desktop computers may have jacks in the front. Sometimes they are in different places depending on the make and model of your computer. These jacks should be color coded and they may also be labeled with small graphics (which may not look the same as the ones on your headphones).

Here are examples from two typical desktop computers of different ages:

Here is an example from a typical laptop:

On your computer, the headphone jack is almost always green and the microphone jack is pink or red. The blue jacks in the first two photos are not the correct ones.

Headset Volume/Mute Controls

Your headset may be equipped with controls on the cord. If so, there is usually a rotating volume control and a mute switch similar to the one shown below:

After plugging the headset into your computer, be sure that the volume is turned to about halfway and that the microphone is not muted.

Adjusting Microphone Volume

You can adjust your microphone volume within Wimba Classroom by using the speaker slider in the media bar.

  1. Click the icon that looks like a person's torso to view the slider.

  2. While speaking into your microphone (press control on your keyboard), drag the slider arrow up or down to adjust your mic volume.

    When you are speaking, the green/yellow/red bar on the right side of the status bar indicates the volume of your microphone. If your volume is frequently in the red zone, your microphone is probably too loud. If your volume is in the low end of the green zone, your microphone is probably too soft.
