Digital optical is a type of audio connection in home theater systems and stereo systems for automobiles. Digital optical is a physical connection that uses fiber optics to transfer audio data from a compatible source device to a compatible playback device using a specially designed cable and connector.
Is optical audio better?
Both optical cables and HDMI cables are capable of transmitting multi-channel, high quality audio, with major advantages over more traditional analog audio connectors. However, HDMI supports newer, higher resolution audio standards, like Dolby TrueHD, and DTS HD Master Audio. Optical cables do not.
How does digital optical audio work?
A digital optical cable transmits digital signals as on/off pulses of red light that go between the components. The light itself is a basic LED light, not a laser light. Optical cables are immune to the effects of Radio Frequency Interference (RFI) and Electromagnetic interference (EMI).
What is the difference between optical and digital audio?
What is the difference between a digital optical and digital coaxial connection for audio? A Digital Optical connection uses a fiber optic cable. The digital audio bit stream is transmitted using pulses of light through this optical cable. A Digital Coaxial connection uses a cable that has RCA-type connectors.
Is HDMI or optical sound better?
If you’re looking for the best audio quality, HDMI is your choice. While an optical cable can still pass surround sound and super high-quality audio, thanks to the added bandwidth in the latest HDMI versions (2.0) you’ll be able to pass higher resolution and audio.
How do I use digital audio on my TV?
For Android TV™ or Google TV models, if the audio system is not compatible with Dolby Digital or DTS, perform the following steps. Open the Settings screen. How to access Settings. Select Sound, Display & Sound, or BRAVIA Settings. Select Audio output. Select Digital audio out, then set to PCM.
What cable gives best sound quality?
And, in our experience, compared to optical, a coaxial connection does tend to sound better. That’s because it has greater bandwidth available, meaning it can support higher quality audio up to 24-bit/192kHz. Optical is usually restricted to 96kHz.
Is optical better than Bluetooth?
Bluetooth transmission depends on the bandwidth of the radio transfer technology, hence the need for signal compression. Whereas for optical audio, there is no compression of the signal. Therefore, optical audio quality will be better than Bluetooth audio as compression introduces some losses.
How do I know if my TV has optical audio output?
You can check if your devices support TOSLINK audio cabling by looking on the back of the device for the distinct TOSLINK port. 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.
What is the best way to connect a soundbar to a TV?
The best way to connect your soundbar to your TV is with an HDMI cable. This is because HDMI transfers audio digitally, which means it will be raw and uncompressed. Also, HDMI cables can handle the most high-end soundbars, including ones that support surround sound.
How do you connect a soundbar to a TV without an optical cable?
There are many ways to avoid using HDMI or optical connections. You can connect wirelessly with Bluetooth, or use a 3.5 mm AUX cable, RCA cables, or even an auxiliary device that converts coaxial cable to another kind of connection.
Can you use optical audio with HDMI?
Both HDMI and optical pass digital audio from one device to another. 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.
Do I need an optical cable for my soundbar?
If your TV or soundbar doesn’t have an HDMI connector, you need to use an optical cable. This small port gives your TV a new sound experience. Keep in mind that an optical cable doesn’t support HD audio formats such as Dolby TrueHD and DTS-HD Master Audio.

Do all TVs have optical output?
Before you go out to buy cables, it’s worth checking the back of your TV, most TVs have an optical connector, but not all TVs support digital coaxial.
Can I connect speakers directly to my TV?
Some Android TV™ or Google TV™ models can be connected with speakers via Bluetooth. For more details about Bluetooth connection, refer to the article below.
Do all tvs have digital audio output?
It has a fiberoptic (TOSLINK) digital output — this is actually required on any television that calls itself an “HDTV.” This would use a standard fiberoptic cable, but only if your home theater system has an available fiberoptic input.
Is optical louder than HDMI?
The major difference is that HDMI cables can pass higher resolution audio which includes formats found on Blu-ray like Dolby TrueHD and DTS HD Master audio. Fiber optic cables won’t be able to transmit these high-res sound formats. You will get quality sound only as you get with HDMI cable.
Is optical audio superior?
Optical cables transfer video or audio data between sources. Optical digital audio connections send superior audio signals between devices. They are always a good choice for your audio system. They are usually more expensive than coaxial cables but transfer audio signals more effectively.
Does optical cable affect sound quality?
So if you’re getting a Dolby Digital signal, and it’s not cutting out, your optical cable is fine. 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.
