When I first bought my soundbar, connecting it was flawless. In a few minutes, I had finished setting-up the soundbar and started using it. About two weeks ago, I got a call from a friend who had difficulties connecting his soundbar to his television set and needed a little help. Upon inspection, his TV set had no optical cable.

Now, I know most people have faced this problem; you recently bought a soundbar but connecting it to your TV seems to get in your nerves, well, connecting a soundbar to a TV is not as hard as you think. Below I will guide you in different ways to connect a soundbar without using an optical cable.

There are different ways you can connect your soundbar to your TV set, here are the different ways to achieve connectivity:

  1. Using HDMI with ARC support
  2. Using Wireless connectivity via Bluetooth
  3. Using traditional RCA cables
  4. Use of the Auxiliary (AUX)input


Connecting your soundbar to your TV is a rather simple process. However, before connecting your soundbar, your TV set will need to support ‘HDMI-ARC’ which allows audio to travel on both sides along the cable. ARC stands for ‘Audio Return Channel’ and was introduced in 2009 and lets you use HDMI as both an audio input and output.

Most HDMI ports that come on TVs are input only; this means the port will not be able to send anything from the TV, they only receive data.

If your TV set supports ARC, you will be able to connect all your kits (game consoles. Set-top boxes, etc.) to your soundbar and then use an HDMI cable to connect your soundbar to your TV set.

To connect your sound bar to your TV using HDMI, follow the following steps:

a. First, make sure both your TV and soundbar are turned on.
b. Locate the HDMI OUT port on your soundbar and plug in one end of the HDMI cable.
c. On your TV set, locate the HDMI IN (ARC) port and plug in the other end of the HDMI cable and you are ready to go!

With new soundbars, you will have to select HDMI option for sound to be played.

Does connecting a soundbar with HDMI come with its advantages? The simple answer is yes; using HDMI cable makes it possible to transmit large amounts of uncompressed audio data.

HDMI connections will also be able to process new sound formats like Dolby Atmos and DTS: X and can cope with sound systems from 5.1, to 7.1 surround sound and even higher.


When you connect your soundbar to your TV set via Bluetooth, you can be sure you will be free from the hassle of using cables.
So, how do you connect your soundbar to your TV with Bluetooth?

First, you have to make sure both your TV and soundbar support Bluetooth technology. To do this, you can:

• Read the specs of your TV or Soundbar
• Call or ask the maker’s sales support

If your TV or audio source lacks Bluetooth, you can use a TaoTronics BA10 Bluetooth transmitter to turn it into a Bluetooth capable device. Pair the transmitter to your soundbar, and you will hear audio from the TV from your Soundbar.

Different TV sets have different modes of accessing the Bluetooth option, so be sure to check your manual on how to do it. You can also call support to guide you on how to go about doing this.


If you have ever hooked up a VCR or CD player to your TV set, then you might be familiar with an RCA cable.

A simple RCA cable has three color-coded plugs extending from one end of the cable that connects to your devices. The wires are connected corresponding to their colors.

The colors used in an RCA cable are usually red and white or black for both right and left audio channels and yellow for video.

If your TV supports RCA inputs, you can follow the below steps to connect it to your soundbar.

1. Power off your Soundbar and TV before a connection
2. Check for the audio in port on your soundbar and plug the black end RCA cable in
3. Connect the white, and red RCA ends to their corresponding audio out ports on your TV set
4. Power on your TV and your soundbar

If this connection is successful, all TV audio will be sent to the soundbar and be output through the soundbar speakers.

You can also use the above steps to connect a soundbar to any other device that supports RCA like a game console, CD player, cable box, satellite receiver, etc.

Auxiliary input facilitates audio input and output from different electronics.

The main types of AUX output ports are 3.5mm jack on head units or your phone. Tthere is also another kind of jack, the 1/4″ jacks. Know the difference between 3.5mm vs 1/4″ jacks here.

The main benefit of using aux inputs is, you can use them with almost all audio devices.
