Securely connect one end of the optical digital cable to the optical out on your TV . Connect the other end to the optical in on your home theater or stereo system. The optical cable works properly if you see a red light on both ends.
The Bottom Line: Most Blu-ray, game consoles, and similar devices do allow for HDMI cables. However, Digital Optical cables can provide sound that is equally as good if your device does not allow for HDMI use .
A fiber optic cable is simply several small strands of polished plastic specifically designed to transfer light. The digital audio signals are transmitted through the cable as pulses of light. They’re immune to electrical interference, and the signal holds up better over longer distances.
Connect the end of the HDMI cable that is not attached to your Roku player to an available HDMI input on your TV . Connect an optical cable to the optical output on your Roku player. Connect the opposite end to an optical (or S/PDIF) input on your AVR or soundbar. Note: Only some Roku players include an optical port.
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.
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 .
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.
The audio signal stays in a digital format using either of these cables. The differences between the two connections are as follows: A Digital Optical connection uses a fiber optic cable. The digital audio bit stream is transmitted using pulses of light through this optical cable.
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.
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.
Both HDMI and Optical cables are all going to give the same quality signal. The build quality of the cable may differ, but the signal it carries won’t. There are different types of optical , but again, other than better build quality, a fibre-optic is the same whatever the price.
Yes. The Ultra is the only current 4K Roku device to have an optical output , so it can pass surround soundtracks to any device with a matching input. With the Premiere+ and Premiere, your receiver or sound bar has to pass 4K and/or HDR signals via HDMI, and most such devices sold before 2016 do not.
Yes, the TCL Roku TV features an optical digital audio output . An optical audio cable , sometimes called a TOSLINK cable , is needed to connect to the sound bar. If the sound bar doesn’t have an optical audio input, the headphone jack on the back of the TV can be used to run analog audio to the sound bar.
