How to Get Sound From Projector to Speakers?

Many modern projectors have built-in speakers. But if you need to cover a large room or want to obtain a higher-quality audio reproduction, you have to connect speakers to the projector. In this article, I will cover how to get sound from projector to speakers depending on the capabilities of these devices.

The Methods of Connecting Speakers to a Projector

There are wired and wireless methods of hooking speakers to a projector. Some of these connection types are also suitable for connecting a projector to a phone. Depending on the equipment you are using, you will encounter setting up a connection between the projector and:

  • Stereo speakers
  • Soundbar
  • Bluetooth speakers
  • A/V receiver

Types of connections to use a projector with speakers

As every projector and speaker set has different inputs and outputs, it will be fair to break down connection methods based on the available connectors:

  • 3.5mm jack inputs and outputs. – Audio jacks will let you send a stereo signal to a set of speakers or a soundbar.
  • RCA connectors. – If your projector has RCA connectors, you can hook it to stereo speakers (each speaker will need one cable).
  • S/PDIF connection. – It transmits the highest quality sound through the coaxial cable but will require you to use a medium between your projector and speakers since speakers are not built with it.
  • Optical/TOSLINK. – It is used for a soundbar to deliver a surround sound experience.
  • Bluetooth. – Works great for sending sound from projector to speakers wirelessly.

How to connect a projector to stereo speakers

Note that only active stereo speakers can be directly hooked to the projector via corresponding cables and adapters. If you have passive speakers or a complicated home theater system, you will need to use an AV receiver to pass audio to the speakers.

In case your speakers are wired together, you can use a single 3.5mm audio cable to connect them to a projector. However, most speakers use separate left and right channel RCA connections. So if the projector has one 3.5mm audio output and speakers – RCA inputs, you will need to get a 3.5mm to 2x RCA stereo audio splitter.

To connect speakers to the projector:

  1. Place your speakers in the desired location and plug them into the outlet.
  2. Connect the cable to the output on your projector.
  3. Connect another end of the cable to your speakers.
  4. Turn the projector on and regulate the volume.

Connecting a soundbar is similar to hooking stereo speakers to the projector, except you have one more connection option – TOSLINK (if both support optical connection). So, here is what you should do:

  1. Position the soundbar in the desired location and plug it into the power source.
  2. Connect the cable to the output on your projector.
  3. Connect another end of the cable to your soundbar.
  4. Turn the soundbar on and adjust the volume on your projector.

If you have passive speakers or a highly sophisticated home theater system, you will need to send a sound from your projector to speakers using an A/V receiver. Here is a quick outline of how you can do that:

  1. Hook all your speakers to a receiver using a speaker wire or coaxial cables.
  2. Connect all audio and video inputs you plan to use to a receiver.
  3. Insert an HDMI cable into one of the receiver’s video outputs.
  4. Plug the second end of the cable into the video input of your projector.
  5. Set the receiver source to your desired input, and get the video output to the projector.
