All inputs get amplified while transmitting audio signals. While browsing for soundbars you’ll hear from many salesmen that the inputs don’t amplify. You should just smack their faces or just walk away. If the input doesn’t amplify, you can’t control volume level. So, keep this in mind that sounds from optical inputs will surely be amplified.
Optical cables can transmit up to 5.1 surround channels very well. With the optical cable, you can connect different media components directly to the TV. The optical cable transmits the audio signals from the TV to the soundbar via optical output. You can change the sources with the remote of your soundbar.
Usually, the soundbars use 2 kinds of technologies to stream virtual surround sound.
The first kind is “sound expander” technology. This system allows the sound coming from the speaker to sound to fill up a larger space. In reality, they are only expanded stereo sound not the “surround sound”.
The second type is “virtual sound” technology. It’s truly surround sound. This technology provides expanded the stereo experience. At the same time, this technology can simulate the sound that comes from many directions. The system doesn’t require multiple speakers to stream audio. You will find this soundbar as 4.1, 5.1, 7.1 channel surround soundbars.
If your TV doesn’t have any inputs for optical cable, then just use HDMI connections. HDMI connection is definitely a better alternative. By the HDMI connection, you can even transmit 7.1 or more surround channels. This connection also allows you to transmit the uncompressed high fidelity streams.
To connect the soundbar to your TV via HDMI follow the steps:
Connecting the soundbar with the TV by optical cable is relatively easy than other ways. But many TV doesn’t have the input for optical cable. If your case is similar, use HDMI connection alternatively. HDMI connection is not so difficult. Rather, by HDMI connection you can join two or three media components with your TV. I think from the primer, you’ve got the facts about how to use HDMI cable. So, quickly connect your TV to the soundbar and enjoy the best quality audio.
