RCA cables transmit analog, or non-digital, signals. Because of this, they cannot be plugged directly into a computer or other digital device. RCA cables connect amplifiers to all sorts of devices.

Besides, Can I use yellow RCA cable for audio?

One colour, usually the yellow one, is responsible for the video signals. It only carries analogue video, no audio. The “composite video” refers to the yellow cable in the RCA cable bundle; yellow, red, and white.

Also, Is RCA or optical better?

Three of the most commonly talked about cables through the decades are RCA cables, optical cables, and coaxial cables. … Meanwhile, RCA cables are associated with analog signals. This is why optical cables offer superior sound quality and HDMI offers superior video and sound quality to RCA.

Herein, Is RCA good for audio? You’ll be fine with either cable. RCA and 3.5mm are meant to carry low-power analog audio signals, so they don’t need to be extra thick or especially capable. However, you’ll find that in most home audio setups, RCA is more commonly used because most audio equipment use RCA, rather than 3.5mm.

Should I use RCA or optical?

If the distance is sufficiently less than 50′, within the length of available optical cables, use optical. If not, you’ll have to use the RCA cables. If it sounds good, fine. If you get hum or RF rubbish, look for a better system.

24 Related Questions and Answers

Is red RCA left or right?

They are often color-coded, yellow for composite video, red for the right audio channel, and white or black for the left channel of stereo audio.

Can I plug RCA into YPbPr?

A cable with RCA connections can be used for SPDIF, audio, composite video and component video without any problems. … The same cables can be used for YPbPr and composite video.

Does the color of RCA matter?

A typical RCA connector on a cable can be used to transmit audio or video. Usually the yellow end denotes composite video (all the signals combined for the video), and the red and black ends are for audio, but it doesn’t matter – that is just to help you hook them up properly; a color code for you.

Does RCA sound better than aux?

The difference in sound quality is minimal. Since both 3.5 and RCA are unbalanced connection. They are still subject to noise from the common ground. 3.5 commonly use in headphone and portable music player.

Is coaxial better than RCA?

Coaxial audio cable is better than analog RCA cables if and only if you can use it. Fiber optic cable sends the same digital stream as coaxial audio cable. Only cons, decent audio cable has similar capacitance than coax and bandwidth to give away.

Can I use a RCA cable for digital audio?

The electrical signal pulses through the copper wire at the heart of the coaxial cable. … Because of the cost, you might be tempted to use a standard analog RCA audio cable to make a digital connection. Not a good idea. A traditional RCA cable isn’t shielded, nor does it have the bandwidth that coaxial cable provides.

Is RCA good quality?

The RCA cable is also used for connecting audio or stereo devices to transmit sound signals. In this case, the cable only transmits audio signals. It is usually of very high quality and should be like that for the signal to be of high quality.

Which is better Spdif or RCA?

RCA can be both audio and video, while SPDIF only transmits an audio signal. If you want better sound quality, though, then SPDIF is the better choice.

Are all RCA cables the same?

Now there are fundamentally two types of RCA cables: composite and component. They differ only in terms of quality or type of the signal they carry. The composite type has three lines including one for video and the other two for audio which is usually used with stereo devices.

What happens if RCA cables are backwards?

It will swap the left and right signals, reversing the sound field. With some recordings, this will make a big difference (a symphony orchestra with the strings on the right) while with others, it won’t make a difference that matters at all.

What is the blue RCA cable for?

Digital audio cables are orange. In a surround sound system, there are six additional cables to the usual red and white. If there is a center speaker, the cable will be green. Left surround and right surround speakers are blue and gray, respectively.

Can you plug RCA into RGB?

The Red-Green-Blue RCA ports are video only and cannot be plugged or connected to the RCA Yellow-White-Red ports. The Red-Green-Blue RCA ports are what is known as ‘Component Video’. Component video is pre-cursor to digital HD ports (HDMI usually).

Can you plug RCA into component?

You can use any RCA cable (they’re all the same thing even if they have different coloured heads) to connect composite or component video. What is important to know is that they’re not interchangeable – ie, composite out has to go to to composite in, and similar for component.

Can I use HDMI and RCA audio at same time?

You can use both at the same time. Plug in the streaming device with an HDMI cable for an immersive display and external speakers via RCA cables for surround sound. … The shorter the cable, the fewer issues it will face when passing a signal.

Can you plug RCA into aux?

If you have an line level RCA audio output it should work fine into any aux input. If the aux input has a 3.5mm stereo mini jack then you will need a cable with 2 RCA at one end and the stereo mini plug at the other. They also make adapters if you already have a cable you want to use.

Which cable is best for audio?

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.

Are coaxial and RCA the same?

Though coaxial audio cables resemble RCA cables in the shape and size of their connectors and can be interchangeable because they both have 75 ohm impedance and similar bandwidths, coaxial cables are thicker and have the same shielding as coaxial video cables to minimize interference.

Can you convert RCA to coaxial?

However, here we are talking about cabling which carries both video and audio signals. While it is possible to make an RCA to coaxial converter simply by producing a physical adapter to make the cables fit the socket, this won’t usually be enough to get the picture on to the TV set.

Which is better SPDIF or RCA?

RCA can be both audio and video, while SPDIF only transmits an audio signal. If you want better sound quality, though, then SPDIF is the better choice.
