1.XLR Cable And RCA Cables-Pins On The Connector

First off, what do RCA and XLR stand for?

RCA denotes the Radio Corporation of America, XLR denotes the External Line Return Cable, both are styles of electrical connectors.

You will find XLR cable on professional audio, video, and stage lighting setup. The XLR cable has three pins- positive, negative and ground and circular connectors, the pins on the two sides face the male- connector and female connector.

The one in the middle (Pin 1) is always the ground signal on the XLR pinout. RCA cable has only one pin. The pins help in transmitting balanced or unbalanced signals.

2.Sound Transfer Over Distance

XLR cables pass balanced audio. RCA cable transmits unbalanced audio. If you want to connect your guitar to a nearby amplifier, you may go for RCA cables. It carries signals using two wires- a sign and a ground.  The signal wire sends the audio signal to the destination. The ground wire is like a reference line. But along the way, it picks up unwanted noise from the surrounding. So it is best suited for short distance audio transfer.

XLR cables can send balanced audio signals over long distances. Along with the ground, two wires carry the copies of the message of opposite polarity. They are Hot and Cold wires. As the cold wire gets to the end of the cable, the signal polarity reverses. The two signals are in sync now. As the signals move, they pick up noise but get canceled due to CMRR (Common Mode Rejection Ratio).

3.XLR Cable And RCA Cables-Voltage Signal

The spectrum of voltage that the cables transmit also varies. While XLR cables can carry signals of the energy of 4V, RCA cables can send signals of 2V. The 4V is the signal difference between the two voltage signals applied at the two wires. Each sign has a max amplitude of 2 V.

You may change an RCA cable to a balanced XLR cable using suitable cheap adapters. Connect the signal from the center pin of the RCA plug to the hot pin of XLR cable. Then connect the earth wire to the ground. But if you attempt to convert XLR to RCA, you will lose all the noise reduction benefits. You will get unbalanced audio signals: XLR cables generally carry 4V audio signals, and RCA can transfer 2V signals. It is difficult to control the loudness in XLR to RCA conversion.

5. XLR Cable And RCA Cables-Podcasting Studio

If podcasting is what attracts you, then focus on high-quality content and audio. The signal should be free from noise, high audio quality, and should be a balanced signal. You will, of course, not want a cheap cable to ruin the quality of your audio. XLR cable excels in noise reduction, which will enhance the quality of your audio chain in your podcast. It is because of these facts that XLR cables are also known as microphone cables.

6.Stereo Sound System

A stereo sound system can create an effect of multidirectional sound sources. RCA cables can handle the stereo sound system better than any XLR cable, RCA cables can connect devoices like VCRs, DVD players, or TV sets. RCA cables are the simplest and the best way of connecting your TV set to external speakers. RCAs can carry only stereo sound.

It will enable you to get a superior experience of a movie on a TV or a laptop. The RCAs carry two channels- left and right. Red and white usually mark the two cables. These cables connect the output port of the TV to the input port of the speakers. You can also use RCA cables to produce high-quality stereo sound in your car.

7.Recording Studio

Do you have a recording studio? Are you looking to get clear audio? Sure, you can get a great microphone. Or the top-quality machine. The one thing you cannot miss out, though, is an XLR cable.

XLR cables have gained the popularity of microphone cables, and they carry a balanced audio signal. They reduce noise by using Common Mode Rejection Ratio technology. Thus, the quality of the signal it carries is better.

In recording houses, you do not want to compromise on the quality of sound.  Recording studios would like to get rid of all surrounding noise. They focus on extracting good quality audio signals. XLR cables, with their 3-pin design, can meet the requirements of recording studios. You will feel the difference as soon as you use it.

8.Home Theatre Setup

Perfect matches give the best experience. Adorned your home with a high-quality home theatre? You shouldn’t focus on the video alone. Sure, 4K looks excellent. But what about the audio? Wouldn’t you want some great surround sound?

You need to use some quality cable to get the proper audio signals. Otherwise, the quality of the sound produced will not be as excellent. Poor cables will allow a lot of unwanted noise to interfere and degrade the sound quality. Weak links in your audio system will not let you enjoy the music to its full extent. RCA cables are perfect in-home theatres.

They do not let noise hamper the sound, as audio transmission in home theatres is over a short distance. RCA cables allow you to optimize your sound system without exceeding your budget. The shielding around the cable will prevent electromagnetic and radio interference. RCA cables will let you enjoy sound music and clear pictures of home theatre. You may need eight audio channels of RCA for this, but a single XLR cable cannot handle home theatres.

9.Live Performance

Are you looking to set up a stage? You wouldn’t want things to go wrong.

You need no noise interruptions-high sound quality. Balanced signals. Long-distance transmissions. And your stage is all set to unfurl the curtains. Be it live music shows or open-air theatres, or stand-up comedy shows, and the audience loves good sound quality. And what better than XLLR cables? The cables meet all the above conditions and more.

Connect them to good quality speakers and amplifiers. Watch the live performance rock. Feel the crowd going awestruck by the sound. XLR cables make the sound loud, noise-free, booming, clear, crisp, and pleasant to the crowd.

Audio cabling comes in these two basic analog cables- XLR cables and RCA cables. RCA bears out in the home theatre and stereo sound system. It also works great in other short distance audio transfer. Also, XLR cables go a long way in noise reduction. They top the list in recording studios and podcast stations.

The cable-type depends on the purpose you will use it for. The specifications depend on the applications of the cable. RCA and XLR, both these types of cable, find great use in projects.
