Don’t have HDMI or optical cables at hand?
Most people have HDMI cables today to connect soundbars and TVs. One reason to own an HDMI cable with a soundbar is the single cable can transmit audio and visual data in one go.
Let’s say, for some reason, you don’t have the optical cable and HDMI at hand. Or your television or speaker bar does not have the same slot for each.
When you can’t miss that TV show, but it lacks the confidence to blast off clear dialogues and sharp audible sounds, you must connect that audio bar by hook or by crook.
It’s time to gather your resources and look at the ports at the back of your television and soundbar. Any slot that matches them can connect the sound bar to the TV.
Things to consider before choosing an alternative to HDMI and optical cables
While HDMI and optical cables are optimum connections for TVs and soundbars, there will be times when they will not be available.
Whether it’s permanent or temporary, here’s what you must consider when choosing an alternative working connection.
1. Compatibility
The significant factor when choosing an alternative is compatibility. These two devices must have a common language that they understand.
They must talk within the same network or communicate with the same technology.
2. Audio quality
Consider the audio quality that each connection will deliver.
If the audio has to downscale to stereo, you may not benefit from the spatial audio advanced formats can offer.
Consider if the connection will lose audio data during transmission.
3. Ease of setup
I, myself, want a plug-and-play setup with less clutter.
If possible, choose a connection that will not require you to buy another device and complicate your setup experience.
4. Range and stability
Wired connections are more stable than wireless connections.
If you are considering wireless options, ensure there will be no interference when you mount the soundbar to your TV.
What are your options?
Go wireless.
You can skip checking the back of your audio bar if your TV and soundbar support Bluetooth or Wi-Fi.
It’s the best alternative to HDMI since this connection can preserve audio in its original form. And the best part of it all is you don’t have to deal with messy wires.
Some devices have built-in wireless connections. And some of them need adapters.
Nevertheless, it’s more challenging to find televisions without any means to connect to Wi-Fi or Bluetooth nowadays.
TVs have various ways to connect to Bluetooth.
But once you find it in your settings, you can activate your soundbar’s Bluetooth. Most speakers, even budget soundbars, connect automatically to audio sources.
Use the 3.5 mm cable.
Some TVs have slots for 3.5mm audio jacks – the ones you use for headphones.
But unlike a wireless connection, your soundbar may not deliver actual sounds, especially for advanced formats.
The cable can only transmit audio data through the right and left speakers. So you won’t enjoy that surround sound you get from a three-channel surround sound speaker.
You only need to plug in a 3.5mm cable to your monitor, and the soundbar will deliver a stereo version of the audio.
Check for your analog cables.
So you own an old TV, and none of the above is possible? Some modern soundbars still have analog or RCA cables.
These cables have color-coded jacks: white, red, and yellow. If your monitor has RCA input slots, you can connect your soundbar to it.
But like 3.5mm, these cables will process audio signals only for the left and right speakers.
Most modern surround speaker bars today are optimized to transmit signals only for HDMI, optical, and wireless connections.
If so, you can use an RCA-to-HDMI adapter, which converts RCA composite inputs into HDMI output.
This plug-and-play solution could save you from buying a new TV but does not guarantee delivering a true high-definition signal.
Try your coaxial cable.
Okay. We’re really going back about two decades from now. But if you have that old TV and still wish to use your soundbar, it must have the thread for coaxial cable. Let’s say– that old monitor without built-in internet.
Coaxial cables are those we use to connect the TV to the satellite. Now, you will not use it directly to your speaker bar, but your old VCR or DVD player can help you link it with the soundbar.
If you don’t want to go through all this stuff, you can use an HDMI-coax converter, splitter, or adapter. However, using this option means you will need another device or power source.
This option may complicate your TV-soundbar setup.
Arc or eArc
Now, let’s take more steps forward.
If you’re thinking of a more advanced audio soundbar setup, that minimalist audio setup with the immersive spatial audio experience, like having 7.1 channels.
Your best choice is connecting your TV using an HDMI with an Advanced Return Channel, known as ARC or eARC (upgraded).
If you are considering future-proofing your home entertainment system, get a soundbar with an ARC or eARC slot.
This connection can transmit the most advanced formats today: the Dolby Atmos and DTS: X.
Fortunately, those TVs released from 2018 onwards support this connection.
However, you cannot simply use an HDMI cable for this. You need specialized cables for this HDMI function labeled as High-Speed HDMI Cable, HDMI with Ethernet, or an Ultra HS HDMI cable.
Here’s another tip!
If your flat screen has an ARC port and your soundbar has an eARC slot, or vice versa, you may not enjoy the sound quality an eARC has to offer. They have to be the same eARC standard! However, they will work!
There are lots of ways to use your TV and soundbar without HDMI!
With the myriad of options available to connect a soundbar to a TV without HDMI, you can surely say that you do not have to depend on these cables alone.
However, there are reasons why every speaker bar available comes with an HDMI cable.
HDMI cable can transmit quality AV signals in one cable. The compatibility for advanced formats leads to a more dependable connection for both TVs and soundbars.
The good thing about audio bars today, as we see on our database, is the flexibility of different ports to make anyone’s purchase worthwhile.
Most manufacturers are racing to ensure their units support advanced audio formats and technologies to provide future-proof audio equipment.
The key to finding the right alternative to HDMI cables is knowing their limitations and which language the devices understand.
And for the curious, you have many chances to explore the possibilities of wireless connections and the versatility of today’s TV and booming soundbars.
