![]() ![]() ![]() There is a setting on the microphone control panel and another on the speaker control panel. On a Windows 10 PC, we can adjust the sound settings to listen to the mic through the speakers. Although we do not recommend the more complicated route of setting this up through the system control panel settings, we include those directions here for Windows 10: Either adjust the sound control panel settings (complicated) or use software that controls the audio automatically (much easier). In order to allow the microphone to play through the computer speakers on a Mac or PC, there are two options. If you already have another microphone plugged into the computer, for instance in a web-cam, you may also need to specify which mic to use. Simply plugging the microphone into the computer's microphone jack should allow you to record audio, but this sound generally does not automatically play through the computer speakers, which would tend to produce feedback. There will likely be more to getting the wireless microphone, or any microphone for that matter, to work with your computer as a PA system in real time. Such adapters are inexpensive and easy to find. Some microphones, for example, have the larger 1/4 inch plug. Of course, an adapter might be necessary depending on the specific devices used. If you already have a higher quality microphone that you prefer to use, this should work fine in place of a microphone that comes with any wireless microphone system. Many wireless microphone kits come with both. ![]() But the lavalier mic might be more comfortable for the speaker. The headset mic might produce a better sound because it is even closer to the speaker's mouth. Hand-held microphones or microphones in web-cams tend to be awkward or be too far from the speaker to produce the clearest sound. The computer probably has a stereo mini jack.īe sure to plug the receiver into the microphone jack, not the headphone or aux jack.Ī lavalier or lapel mic is a good choice because sound tends to be better if the microphone is close to the speaker's mouth. An adapter (shown here) might be needed to allow the receiver to fit the computer microphone mini jack. The receiver could have a mini plug or a 1/4 inch plug. In this image, we see a lavalier (lapel) mic. Microphone type: lavalier (lapel) or headset.Some of the features one should be aware of are: Many different wireless microphones can be purchased at a reasonable cost. Although no software is required to make this work, there is free software available that can make this much easier to set up.Ī wireless microphone has two principal components, a transmitter that the microphone is plugged into and a receiver that plugs into the computer or sound system. Since we are only projecting voice, we can use a very inexpensive wireless microphone system ($20-$50). A wireless mic has the advantage of mobility for the teacher, making it much easier to move around the room if necessary. We will set up the PA system using a wireless microphone and a classroom computer. Although it would be nice to be able to use one's cell phone to set up such a system, we have found that this produces a delay that makes the cell phone unusable as a mini PA system. Our inspiration for this was the advantage of amplifying the teacher's voice during the COVID-19 pandemic to improve communication through a mask and to reduce virus spread when a loud voice is projected. It could also work for mini conferences or workshops. This can be used for a large classroom if a microphone system is not otherwise available. In this lesson we will go through the process of setting up an inexpensive classroom public address system. Wireless Sound - Setting Up an Inexpensive Classroom PA System ![]()
