5 Ways to Connect External Speakers to Epson Projector

Connecting Your Laptop or A Streaming Device to External Speakers

If using a laptop or a streaming stick as your projector’s input source, you can connect your external speakers to the input device instead of the projector.

This is usually the route when your Epson projector doesn’t have a sound output port. For example, a laptop, Fire Stick, or Roku can connect to the soundbar wirelessly.

The final output is more than satisfactory since you no longer have to rely on your Epson projector’s built-in speakers. (If your Epson projector doesn’t have a sound port, it likely has an integrated speaker system.)

Connecting Your Epson Projector to External Speakers

Using AUX Cable

If your Epson projector has an AUX (auxiliary) port, plug in the two male connectors of a 3.5mm cord into the projector and external speakers.

If you don’t have an AUX cable handy, look at these 3.5mm AUX to RCA or 3.5mm AUX cables.

Here is how to connect the devices using the cables:

Step 1: Plug in the power cords of your projector and external speakers and turn on the devices. Dial down the speakers’ volume when setting up things to prevent unpleasant audio noises.

Step 2: Connect one end of the 3.5mm cable to the projector’s AUX output port and the other to the speakers’ 3.5mm port. If the speakers use RCA ports, use the line with the RCA connectors and plug the suitable color connectors into their corresponding ports on the audio device.

Using Passthrough Feature (HDMI ARC/eARC) to Connect to a Soundbar

If your Epson projector supports HDMI ARC/eARC, use the passthrough feature. You’ll need an HDMI cable to get rolling. Here are the setup instructions:

Step 1: Hook one end of the HDMI cable to your projector’s HDMI ARC/eARC port. The other end goes into your soundbar’s ARC/eARC port.

Step 2: Connect the input/source device (laptop, gaming console, or streaming device) to your soundbar’s HDMI IN port.

Step 3: Head to the projector’s sound settings. Choose the Sound Output Device setting and set it to ARC so that the audio output changes to the soundbar from the projector.

Wireless Connection (Bluetooth) to Bluetooth Speakers

Some Epson projectors support Bluetooth functionality, letting users wirelessly connect speakers to the device.

Setting up the wireless connection is pretty straightforward.

Power on your Bluetooth speaker and projector. Then, turn on the projector’s Bluetooth function.

Scan for available Bluetooth devices to connect to. If your speakers have Bluetooth turned on, they should appear in the Epson projector’s “devices available to connect” list.

If the above information seems vague, here are step-by-step instructions:

Step 1: Plug in your projector and power it on.

Step 2: Hit the Menu key on the projector control panel or remote to access the device’s primary menu.

Step 3: Choose Settings and hit Enter.

Step 4: Choose HDMI Link and hit Enter.

Step 5: Next, choose Audio Out Device and then Projector.

Step 6: Go back to Settings by pressing Esc.

Step 7: Choose Bluetooth > Bluetooth Audio.

Step 8: Toggle on Bluetooth and go back to the Bluetooth menu.

Step 9: Put your Bluetooth speakers on discovery or pairing mode.

Step 10: Choose your wireless speakers from the list on the screen a wait for a few seconds. The devices are now connected.

The next time you turn on your projector and wireless speakers, they will connect automatically. To link another set of Bluetooth speakers, follow the steps above.

Step 1: Insert one cable end into the projector and the other into your speaker.

Step 2:Link the source device (laptop, gaming console, or streaming device) to your projector through HDMI.

You can control the audio volume using the projector remote control.

Epson and other projector manufacturers know their devices’ audio chops are not the best, and provisions must be made to connect the device to external audio hardware.

You only have to know how to connect the projector to discrete audio gear, the cables to use, enable Bluetooth for wireless connectivity, etc.

Hopefully, this article provided all the information you needed to connect your Epson projector to wireless or Bluetooth external speakers.
