Audio Setup for Projectors

How are projectors connected to speakers?

You need to connect your speakers and projector via an RCA cable to have audio follow the video. This standard red and white cable has two prongs on it (red for the right speaker; white for the left).

However, some projectors may only have a 1/8-inch audio jack. If your projector only has this, your speakers will need a 1/8 inch input, or you will need to buy a cable converting 1/8 inch audio to RCA jacks.

You can connect your projector to speakers in these ways:

  • Bluetooth.
  • An optical digital audio cable.
  • A 3.5mm audio cable.
  • An RCA cable.
  • Another way you can set up your projector’s sound is by plugging in speakers directly into your laptop or computer, sending the signal to the projector instead of the projector. But that is not what we are talking about here.

Types of connections you can use to connect a projector to speakers

You can use a wide variety of different types of cables to connect your projector and speakers.

An RCA cable has two prongs, one red and one white, for the right speaker/left speaker connection.

There is a digital optical connection between the projector and speakers. A digital optical connection is much better than RCA cables, which is the best way to connect a projector and speakers.

You can have a speaker with Bluetooth capability; if your projector is also Bluetooth enabled, you can connect it to the speaker.

There is also the possibility of a standard headphone jack connection compatible with both speakers and your projector.

How to Connect a Projector to Stereo Speakers

  1. Locate the speakers where you want them and connect them to power or insert the batteries.
  2. Connect one of the audio output options on your projector to an audio cable.
  3. Connect the other end of the cable to your speakers.
  4. Adjust the volume on your projector to suit your needs.

How to Connect a Projector to a Soundbar

Connect your projector to a soundbar using an RCA cable.

Turn both devices on simultaneously, then adjust volume levels until they are balanced for optimal sound quality.

How to Connect a Projector to an A/V Receiver

Connect your projector to an A/V receiver using a digital optical cable.

How to Connect Bluetooth Speakers to Your Projector

Power up your equipment and ensure that it is working properly before you connect anything.

Turn on your projector, then connect to the Bluetooth speaker via the control panel.

Adjust volume levels so you can hear both devices’ sounds appropriately.

How to Connect Standard Speakers or Headphones Directly to Your Projector Using a Cable Adapter

Connect one end of your cable adapter to the headphone jack on your projector.

Connect the other end of your cable adapter to a set of standard speakers or headphones.

Adjust volume levels to ensure that audio is appropriate for everyone in attendance.

Frequently Asked Questions About Connecting A Projector To Speakers
