Go to Parts and Accessories. 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. Turn on your TV.
Both can pass multi- channel audio, like Dolby Digital. 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. These formats can’t get transmitted across optical.
How to Remove an Audio Optical Cable Turn around the first device from which you want to disconnect the optical cable . Locate the optical cable you want to remove . Grip the head of the plug and gently pull it away from the port until it comes out. Roll up the cable and follow its path to find the port it is plugged into on the other end.
What Does an Optical Digital Audio Cable Do? An optical digital audio connection is used to send digital audio signals between devices. It supports uncompressed PCM stereo audio, and 5.1/7.1 Dolby Digital and DTS multichannel audio for people with surround sound systems.
Unlike other cabling standards, the optical audio system uses fiber optic cables and laser light to transmit digital audio signals between devices. The port is typically labeled “ optical audio ”, “TOSLINK”, “ Digital Audio Out ( Optical )” or something similar , but you certainly don’t need a label to identify it.
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.
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.
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.
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.
How do I remove my optical audio cover ? Examine the end of the optical cable. Note the presence of a translucent plastic cap covering the lens. Grip the very end of the plastic cap with your fingers. Pull straight back to remove the cap. Insert the optical cable into the connected devices. Push the cable in until it clicks into position.
There’s just a little tiny plastic edge you should be able to get your fingernail under and wedge it out. Or a jewelers screw driver or a decent pair of tweezers. When something like that happens to me, then I just get a small pair of needle nose pliers, and slowly move it back and forth. Until it comes off.
So yes, compared to Bluetooth specs to date, the optical will be of better quality. Neither will be as good as HDMI cable, which allows eight channels at 192kHz sampling and 24-bits/sample to be transferred, uncompressed.
1- Optical Audio – Toslink Cable 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 .
If you’re transmitting PCM, the audiophile answer is that different optical cables can cause different amounts of jitter. The reality is, the digital-to-analog converter in your gear has vastly more effect on the sound. Could a “better” optical cable result in audibly better PCM sound? Doubtful.
