The main downside to a coaxial digital connection is the potential transfer of electrical noise between your kit. Noise is bad news when it comes to sound quality, but it exists in all AV components to one degree or another. Unfortunately, using a coaxial connection enables noise to travel along the cable from the source to your amplifier. High-Speed Automotive HDMI Cable: This type supports the same features as High-Speed HDMI cables but is optimized for the automotive environment.

LG was the first manufacturer to go all-in with the new standard, producing the first 4K TVs to sport HDMI 2.1 ports in 2019. All LG's 2022 and 2023 OLED TVs have up to four HDMI 2.1 ports, with Samsung offering one on most models and four on its flagship sets. Meanwhile, much of Panasonic and Sony's 2022 and 2023 ranges also sport a mixture of ports. High-definition multimedia interface, best known as HDMI, is a modern trending technology forHD signal transmission. It guarantees the transfer of high-definition audio and video from your device to the screen. HDMI cables are easy to obtain, come in various lengths, and are affordable. Moreover, Optical cables give decent sound quality. They’re a better choice in the long run as they’re immune to electromagnetic interference. They are also good if you want to transmit audio signals for a longer distance. So, deciding on the correct cable type depends on what you’re looking for. Since the TV is sending audio to the sound bar, you need to connect the sound bar to an output on your TV.

HDMI ARC gives better sound quality than Optical and is the best option. HDMI ARC cable supports higher sound resolutions and video signals which an Optical cable can’t. If you can, connect these devices to a HDMI 2.1 input. Not all TVs have one, but if it's available you'll get access to better features, such as 120Hz refresh rate, assuming your console and TV support it. What about older devices? Optical Cables and HMDI ARC are made up of different materials. Copper is the primary material used in the production of HDMI cables. It is inexpensive and malleable, which makes the production process easy. Copper has also survived the test of time within the data transmission industry despite being susceptible to interference from electromagnetic waves. On paper, HDMI eARC also makes the handshake between compatible devices much smoother and negates the need to activate HDMI CEC (which doesn’t always work properly) - so operating multiple products shouldn’t require any extra steps to get things up and running. SDI video connections are switchable between standard definition, high definition level A and level B 3G-SDI, 6G-SDI and 12G-SDI. SDI VideoSampling

If your TV can transmit two audio signals simultaneously, one cable can transfer videos and send sound. You may use the HDMI cables for video transmission and the Optical cable for the audio signal. Yes, and it’s similar to the difference between optical and HDMI ARC. As great as HDMI ARC is from an improved bandwidth point of view, it too is limited. It can support Dolby Digital Plus, which is what virtually every streaming service today uses to deliver high-quality surround sound with or without Dolby Atmos. But that’s where it ends.Some devices don’t have an HDMI port for audio-visual connectivity. Optical audio can guarantee good signal quality across all the connected devices.Toshibawas the first to introduce Optical cables in the 80s, and they became the easiest way to transmit Dolby Digital and DTS to your AV receiver. HDMI ARC vs. Optical: Side-by-Side Comparison Connecting both types of wires couldn’t be easier, although HDMI (and optical, to an extent) are going to require a few tweaks in your TV or receiver’s settings. Passive HDMI Cable: Most HDMI cables are passive. That means one end goes into a source and the other goes to a home theater receiver or video display, and the signal is transferred. The cable is also bi-directional, meaning you can connect either end to an HDMI input or output connection. Passive HDMI cables should be able to provide a stable signal for lengths of up 15 feet.

As part of the process, you should consider enabling HDMI CEC (Consumer Electronics Control), so you can turn your TV on and control the volume on your soundbar or amp without the need for multiple remotes. A word of warning, though: turning HDMI CEC on can have some unwanted AV side effects, so you might want to experiment first. Picture the scene. You have a set-top box, games console and Blu-ray player all plugged into your TV via HDMI. There's also HDMI eARC - this works the same as HDMI ARC, but can send higher quality audio signals. It also has to be implemented correctly so it's always running of battery. Many claim they do but in reality they really don't. Sinewave batteries can just produce stable clean power when done correctly, which is often very expensive. Using HDMI ARC does not require a new HDMI cable. Any HDMI cable should be able to cope with the requirements – it’s only when we move on to eARC that this could (potentially) become an issue. But more on that later.so assuming that the dac is equal in quality i would convert at the receiver. I could be mistaken, but my impression is that analog signals, especially unbalanced, low level signals, are susceptible to noise whereas digital signals, especially optical, are not. So you want to keep your analog signal path as short as possible. We used the TENDAK HDMI Audio Extractor to extract HDMI from the Nintendo SNES console, separate the audio and video, then send the audio to Creative Sound BlasterX G5 and the video to a Dell DVI monitor. The HDMI audio extractor did a phenomenal job. We did not experience any issue at all. Firstly, using this HDMI audio extractor, you can extract HDMI signal from the HDMI input and convert it to multichannel audio (SPDIF) or 2-channel analog stereo audio output.

Pretty much this outside the fact that almost all HDMI cables shorter then 10 to 15ft max are copper. Really, you just need a well shielded cable although it's always a good idea to keep all cable runs as short as possible in my experience.The answer to this will depend on the kit you’re using. If it’s a straight choice between coaxial and optical, we’d go for the former. In our experience, a coaxial connection tends to produce better audio quality than optical, allowing for a higher level of detail and greater dynamics. This means that one can only access 5.1-channel surround audio. This is not something to pout over because it is satisfying by most standards. However, Optical audio doesn’t offer sound profiles such as 5.1.2 or 7.1, or 7.1.2. Moreover, Optical audio doesn’t support Dolby Digital Plus, TrueHD, or DTS HD. Can be used with a variety of devices, such as 4K Smart TVs, Xbox, PlayStation 4, Nintendo Switch, Apple TV, headphones, Sony BluRay player and so on
