How to Use a Soundbar With a Projector
By Steve Lander
Some projectors have speakers so that you can include audio in your multimedia business presentations. However, because of the limited space inside the projector, the speakers are often placed close to the cooling fan, and therefore don't sound very good and aren't capable of producing audio that is loud enough for everyone to hear in a large conference room. To get better sound quality or more volume, you can connect your projector's audio output to a soundbar that combines speakers and amplification in one self-contained unit.
Select an appropriate audio cable to connect your projector to your soundbar. The cable needs to have a 3.5-mm stereo plug on one end for your projector. The end that connects to your soundbar needs either another 3.5-mm stereo plug or two phono plugs for a traditional analog audio connection, depending on which connection type your soundbar uses.
Press the "Power" button on your soundbar to turn it off.
Connect your projector to your computer as you normally would. If you are not using an HDMI connection, remember to use a 3.5-mm male-to-male stereo audio cable to connect your computer's Audio Out, Audio Line-Out or Headphone jack to your projector's audio input.
Insert the 3.5-mm plug on your audio cable into the Audio Out or Audio Output jack on your projector.
Insert the other end of the audio cable into the input on your soundbar. Depending on the model, do this with a single 3.5-mm plug or two phono plugs. If your soundbar has a dual-phono input, put the red plug in the jack for the right channel, and the black or white plug into the jack for the left channel.
Press the "Power" button on your soundbar to turn it on. Use its volume control to adjust it to an appropriate volume for your presentation.
