What to know before starting:
It is a good idea to keep your TV and sound system manual. If you can’t find them, download them from the manufacturer’s website. Bear in mind that we have been talking about attaching the TV output connectors to the speaker input connections. The manuals tell you where to find these ports and what options your TV has. Other things to keep in mind are that you need to configure some settings on the TV to tell us to use external speakers, not the small ones we are trying to avoid. If you do not have such an option, you can turn off the volume on the TV completely and use the volume control for your external speakers.
Using RCA Cable:
An RCA cable is one of the simplest ways to connect your TV to your speaker system. They have stereo sound only (2 channels – left and right), do not surround the sound. This is useful if you are using basic stereo or 2.1 speakers. If you use surround speakers, they will only play stereo sound. A pair of cables and connectors is a pair, usually marked red and white. These cables place your speaker or subwoofer unit in the case of 2.1 speakers, from the red and white port on the back of your TV (RCA output port) to the input speaker. You should refer to the manual for TVs and speakers to find out where these ports are located.
Using 3.5mm analog cable:
If your TV does not use RCA connectors for audio output, it may have a headphone output (3.5mm port). You can use it to connect your TV to the speaker. They are similar connectors used in phones, tablets, laptops, etc. For this, you need to use the 3.5mm audio jack on the TV end and the RCA jack on the speaker end. If your speakers use 3.5mm (instead of RCA connectors) for input connectivity, you can use a 3.5mm to 3.5mm cable. This method is also suitable for basic multimedia speakers, but you cannot get surround sound using this cable.
Using an HDMI (ARC) cable to connect a TV to a receiver or soundbar:
HDMI is one of the most preferred methods because it suffers from surround sound with some RCA or 3.5mm connector methods, without any quality loss. Sound speaker setup without HDMI input is likely to support receiver and soundbar surround. Your TV needs an HDMI output port to detect HDMI-ARC. Connect the cable between the two devices using the HDMI cable.
Using an HDMI cable through the TV to your receiver or soundbar:
If you are using a receiver or amplifier setup with HDMI input ports, an HDMI cable will also be used. If your TV does not have an HDMI output port, you can channel your sources (laptop, gaming console, set-top box) through the receiver/amplifier or soundbar using the HDMI cable, and output another HDMI cable from that device to your TV. That way, you can use the remote control of the receiver or soundbar to switch between inputs rather than the TV. You can still hear all the audio through the speaker setup used. If HDMI-ARC is not an option or you want to play music on your receiver / amplifier-powered speakers without ever having to operate your TV, this is easy.
Using Optical Cable:
Optical cables are rarely used, but they offer the same functionality as HDMI. If your TV has an optical output, connect to a receiver or soundbar if the TV is supported. You can transmit surround sound by doing this. These cables are thinner and more discrete than a thin HDMI or complex RCA cable setup. You may need to change the settings of your TV or source to send audio via optical cable.
There are a few simple ways to connect those TVs to their speakers. We recommend choosing a good soundbar or surround sound speaker, amplifier-receiver setup. And if you have not yet regained the image quality of your TV, you must consider.
