Both HDMI and optical pass digital audio from one device to another. Both are better than analog (the red and white cables ). Both cables can be had pretty cheap. The biggest difference is that HDMI can pass higher-resolution audio, including the formats found on Blu-ray: Dolby TrueHD and DTS HD Master Audio.
Digital optical and digital coaxial connections are used to transfer audio signals from a DVD player to an Audio /Video (A/V) receiver or digital recording device. A Digital Optical connection uses a fiber optic cable . The digital audio bit stream is transmitted using pulses of light through this optical cable .
If you want to connect a soundbar to the TV without HDMI or optical , you have two options: go high-tech with a wireless connection or mid-tech with 3.5 mm aux or RCA cables . You can also use an auxiliary device to convert coaxial cables to another type of connection .
Distinguished Member. Dolby Digital is compressed so PCM is better. Dolby True HD, DTS HD MA, Atmos and DTS X are also lossless, so should be similar quality to PCM . If the source audio is stereo, it should only be coming from your front left and right speakers unless you use an up mixer.
HDMI cables can carry both audio and video. It eliminates the need for another cable . On the contrary, when you opt for an optical cable , you will need a second type of cable to transmit your video signal. The total cost of the two cables may end up being more than one HDMI cable .
Higher quality aux cables can also help as they’re better shielded. Optical isn’t foolproof either. In terms of value for money, aux cables are usually cheaper, more versatile, and most commonly found on modern devices than their digital counterpart.
In our experience, a coaxial connection tends to produce better audio quality than optical , allowing for a higher level of detail and greater dynamics.
You can have video from HDMI at the TV’s resolution, and have audio coming from your receiver via optical , which is what I did, or you can have both audio and video going straight to your television, but you can ‘t have both.
The optical cable is a digital audio only cable that sends it’s signals over light making it a fibre optic cable . If you wanted a 7.1 surround sound system you would need to use a HDMI cable instead, but as a soundbar is not a surround sound system this is not required.
Connect one end of the HDMI cable (sold separately) to the HDMI IN port on your TV . Connect the other end to the TV OUT (ARC) port on your sound bar . Then, connect an optical audio cable from the TV’s Optical digital audio out to OPTICAL IN on your sound bar (this is necessary to hear the TV audio).
Connect a Coaxial Digital Cable, Optical Digital Cable, or Audio cable to the Audio Output jack on your TV . Connect the other end of the cable to the corresponding jacks on the A/V receiver or home theater system. Depending on your device, the audio input may be labeled TV INPUT or VIDEO INPUT.
The optical jack is designed to output sound when the video you’re watching contains digital audio (PCM or Dolby Digital® technology). This feature is available on certain digital broadcasts and streaming video, and isn’t supported on standard cable or analog stations.
You will only need to connect your Samsung smart TV’s analog stereo outputs , usually referred to as RCA outputs , to your external audio system such as home theater. Below are the steps to follow: Using the analog stereo cables at your disposal, connect the mini-stereo plug (3.5mm) to your TV’s audio output .
However, if you don’t have HDMI as an option, then an optical audio cable is a good way to transfer the audio between devices. You will be able to hear standard stereo audio and 5.1 surround sound transmissions over an optical connection. Some older devices with HDMI ports don’t support the transfer of audio via HDMI.
