What is the best cable to use for connecting my soundbar to my TV?
The best cable to use for connecting your soundbar to your TV depends on the type of soundbar and TV you have, as well as the audio quality you want to achieve. If your soundbar and TV both support HDMI, an HDMI cable is usually the best option. This is because HDMI can carry both audio and video signals, making it a convenient and high-quality choice.
However, if your soundbar or TV doesn’t have an HDMI port, you may need to use an optical or coaxial digital audio cable instead. These cables can carry high-quality audio signals, but they may not be as convenient as HDMI since they require a separate connection for video. It’s also worth noting that some soundbars may have wireless connectivity options, such as Bluetooth or Wi-Fi, which can eliminate the need for a cable altogether.
What is the difference between an optical and coaxial digital audio cable?
An optical digital audio cable, also known as a TOSLINK cable, uses light to transmit audio signals through a fiber optic cable. This type of cable is commonly used to connect soundbars to TVs, and it can carry high-quality audio signals, including surround sound. Coaxial digital audio cables, on the other hand, use a copper cable to transmit audio signals.
In terms of audio quality, both optical and coaxial digital audio cables can deliver high-quality sound. However, optical cables are generally more resistant to interference and can transmit signals over longer distances. Coaxial cables, on the other hand, are often less expensive and can be more convenient to use, especially if you already have a coaxial cable lying around.
