Hooking up your projector to a soundbar might sound tricky if you’re new to home theater gear. You just want to enjoy big movies with great sound, right? Don’t worry, finding the best way to connect projector to soundbar is simpler than you think.
We’ll walk through the easiest steps so you can get your setup working without any fuss. Let’s make your home cinema sound amazing.
Connecting Your Projector And Soundbar
Many people want to get better sound for their movie nights. Projectors offer a big screen, but their built-in speakers are often weak. A soundbar can make a huge difference, bringing movies and games to life with richer audio.
But how do you get the sound from the projector to the soundbar? This guide will show you the most common and effective methods. We’ll cover the simplest ways first.
Understanding Audio Output And Input
Before we connect things, let’s quickly talk about ports. Your projector sends video and sometimes audio out. Your soundbar needs to receive that audio.
The key is to find the right ports on both devices. Projectors usually have audio output ports, and soundbars have audio input ports. Matching these is the first step to getting sound working.
Method 1 The Simple HDMI Connection
For many modern setups, the best way to connect projector to soundbar is using an HDMI cable. This is often the most straightforward method because HDMI carries both video and audio signals.
How HDMI Works
HDMI stands for High-Definition Multimedia Interface. It’s a digital connection that can send clear picture and sound all at once. If your projector has an HDMI output and your soundbar has an HDMI input, you’re in luck.
Steps For HDMI Connection
- Turn off both your projector and your soundbar.
- Find the HDMI OUT port on your projector. This is usually labeled clearly.
- Find an HDMI IN port on your soundbar. Some soundbars have multiple HDMI inputs for different devices.
- Connect one end of an HDMI cable to the projector’s HDMI OUT port.
- Connect the other end of the HDMI cable to the soundbar’s HDMI IN port.
- Turn on your soundbar first, then turn on your projector.
- On your soundbar, select the HDMI input you used. For example, if you plugged into HDMI 1, choose HDMI 1 on the soundbar’s settings.
- You might also need to tell your projector to send audio through HDMI. Check your projector’s audio settings. Look for an option like “HDMI Audio Out” or “Audio Output” and select HDMI.
This method is great because it’s one cable and it handles everything. If your soundbar also has HDMI ARC (Audio Return Channel), it can be even simpler. ARC lets audio go back from the TV or projector to the soundbar using the same HDMI cable.
HDMI ARC Explained
HDMI ARC is a special feature on some HDMI ports. If your projector has an HDMI ARC port and your soundbar also has an HDMI ARC port, you can use a single HDMI cable for both video to the projector and audio back to the soundbar. This simplifies things a lot.
How to Use HDMI ARC
- Make sure both your projector and soundbar have ports labeled “HDMI ARC”.
- Connect these two ARC ports with a single HDMI cable.
- Turn on both devices.
- On your projector, go to settings and ensure HDMI ARC is enabled.
- On your soundbar, select the ARC input.
This is often considered the best way to connect projector to soundbar if both devices support it because it’s so clean.
Method 2 Using An Audio Extractor
What if your projector doesn’t have an HDMI audio output or an ARC port? Or what if your soundbar doesn’t have enough HDMI inputs? An HDMI audio extractor can help.
This device takes the HDMI signal, splits the audio, and sends it to your soundbar while sending the video to your projector.
What An Audio Extractor Does
An audio extractor acts as a middleman. You plug your video source (like a Blu-ray player or streaming stick) into the extractor. The extractor then sends video to your projector via HDMI and sends the audio out through a separate port, like an optical or analog audio port.
Steps For Using An Audio Extractor
- You will need an HDMI audio extractor, an HDMI cable, and either an optical audio cable or analog audio cables (like RCA cables).
- Turn off all devices.
- Connect your video source (e.g., streaming device) to the HDMI IN port of the audio extractor.
- Connect an HDMI cable from the HDMI OUT port of the extractor to your projector’s HDMI IN port. This sends the video.
- Connect an optical audio cable or analog audio cables from the audio extractor’s audio OUT ports to your soundbar’s audio IN ports. If using optical, make sure your soundbar has an optical IN port.
- Turn on your soundbar, then your projector, then your video source.
- Select the correct inputs on your projector (HDMI) and soundbar (Optical or Analog).
This method works well when direct HDMI connections aren’t possible. It’s a bit more complex with extra cables, but it reliably separates the audio.
Method 3 Using The Headphone Jack (Analog Audio)
Some older projectors and soundbars might rely on analog audio connections. This typically involves using the headphone jack on your projector.
How The Headphone Jack Works
Most projectors have a 3.5mm headphone jack. This port is designed to send audio out to headphones. You can use a special cable to connect this to your soundbar’s analog audio input.
Steps For Using The Headphone Jack
- Turn off both devices.
- Find the headphone jack (often marked with a headphone icon or “AUDIO OUT”) on your projector.
- Find an AUX IN or LINE IN port on your soundbar. This is usually a 3.5mm jack.
- You will need a 3.5mm to 3.5mm audio cable (sometimes called an AUX cable).
- Plug one end of the cable into the projector’s headphone jack.
- Plug the other end into the soundbar’s AUX IN port.
- Turn on your soundbar and select the AUX input.
- Turn on your projector.
- You may need to adjust the volume on both the projector and the soundbar for optimal sound.
This is a simple method for older equipment. However, analog audio can sometimes be lower quality and more prone to interference than digital connections like HDMI.
Method 4 Optical Audio Connection
Optical audio, also known as TOSLINK, is a digital audio connection. Many modern soundbars have optical inputs, and some projectors can output audio this way, often through an audio extractor.
How Optical Audio Works
Optical cables transmit sound as pulses of light. This provides a clean digital signal. It’s a good option when HDMI isn’t available for audio.
Steps For Optical Audio Connection
- Turn off both devices.
- If your projector has an optical audio OUT port, connect an optical cable from it to the optical IN port on your soundbar.
- If your projector does not have an optical OUT port, you might need an HDMI audio extractor that has an optical audio OUT port. Connect your video source to the extractor, send video to the projector via HDMI, and connect an optical cable from the extractor’s optical OUT to the soundbar’s optical IN.
- Turn on your soundbar and select the optical input.
- Turn on your projector or video source.
- Ensure your projector is set to output audio via optical if it has that option.
Optical is a reliable digital method. It’s a great alternative if HDMI ARC or direct HDMI audio isn’t an option.
Troubleshooting Common Issues
Sometimes, things don’t work right away. Don’t panic! Here are a few things to check.
No Sound At All
- Double-check all cable connections. Make sure they are pushed in firmly.
- Verify the correct input is selected on your soundbar.
- Check the audio output settings on your projector. Make sure it’s set to send audio through the correct port (HDMI, Optical, Headphone).
- If using HDMI ARC, ensure ARC is enabled in both devices’ settings.
- Try a different cable. Cables can sometimes fail.
Sound Is Delayed (Lip Sync Issues)
This is common with different audio and video processing times.
- Look for an “Audio Delay” or “Lip Sync” setting on your projector or soundbar. Adjust it until the audio matches the video.
- If using an audio extractor, some extractors have a delay setting.
- The simplest connection (like HDMI ARC) often has fewer delay issues.
Low Volume
- Turn up the volume on your soundbar.
- Also, turn up the volume on your projector’s audio output if it has a volume control.
- Ensure you are not using a volume-limited headphone jack setting on the projector.
Choosing The Right Connection For You
The best way to connect projector to soundbar really depends on the ports available on your specific devices.
- For most modern setups: HDMI or HDMI ARC is the easiest and highest quality.
- If HDMI ARC isn’t available but you have HDMI ports: A direct HDMI connection sending audio might work.
- For older projectors or limited ports: An HDMI audio extractor is a very useful tool.
- As a fallback or for older gear: Optical audio or the headphone jack can work.
