In a nutshell, a balanced interconnect has somesonic benefit over unbalanced. In equipment where you have bothoptions, it's wise to chose XLR over RCA. You willlikely see more balanced cables with XLR connectors,because they are generally more common for balanced audiofor this very reason..
Likewise, people ask, can RCA be balanced?
RCA Cables RCA Audio Cables are an unbalanced analog audioconnection that sends stereo audio over a right channel (red tip)and left channel (white or black tip). Because they're unbalanced,they typically don't run over 25 feet.
Secondly, what does XLR balanced mean? XLR and TRS cables are used to transmitbalanced audio from one balanced device to another.Unbalanced cables are less complicated, but they're much moresusceptible to noise problems.
Similarly, you may ask, do balanced cables sound better?
Aside from these exceptions, balanced cables area huge improvement over unbalanced. They have bettersignal-to-noise ratio, much lower impedance signals, andalmost no external noise or distortion.
Why are XLR cables better?
The XLR is used a lot because it is solid, andlocks the cable into the socket. The 1/4" TRS plugs are usedbecause they are physically smaller and cheaper. Depends on whatequipment you're connecting with them. If they're balanced on bothends, inserting the unbalanced option between them WILL degradeyour signal.

Unbalanced Cables and Signals A standard TS (or “tip-sleeve”) guitarcable is the unbalanced cable you'll run into on stage most.Standard RCA cables used for many AV components are alsounbalanced cables. Unbalanced wiring uses just twoconductors and is susceptible to picking upnoise.Do RCA cables affect sound quality?
Do RCA cables make a difference in soundquality? Only if they're broken, or unusually susceptible tonoise. Cables can do nothing to "increase"sound quality, but in some rare cases they can be designedso poorly that they pick up noise, or make poorconnections.Can I use unbalanced cables on balanced outputs?
Can I Use Unbalanced Cables with BalancedEquipment? You can — with some caveats. If you useunbalanced cable that doesn't carry the inverted signal,the initial signal is still carried across the cable,so it will work. It may just be noisier and the level may belower than if you used a true balancedconnection.What is a balanced signal?
Balanced audio uses three conductors to carry theaudio signal. Two of the conductors carry negative andpositive signals (audio is an AC signal), and thethird is used for grounding. With an unbalanced signal,there are only two conductors. Generally, +4 db, balancedsignal are the way to go for long cable runs.Should I use balanced or unbalanced cables?
Unbalanced cables certainly still have a greatvalue as well. You will need to use an unbalancedcable when your connections don't supportbalanced. Also many instruments (like guitars) have outputsthat only support unbalanced signals. Sometimes you don'thave a balanced cable so an unbalanced is your onlyoption.Do balanced headphone cables make a difference?
The current into and out of a two-wire network is alwaysequal and opposite. This means that the two-wire transducers usedin headphones always see fully-balanced current. Italso means that the headphone drivers are completelyignorant of the difference between single-ended andbalanced-drive voltages.Can you use XLR microphone cable for powered speakers?
The only exception for the use of XLRmicrophone cables for XLR speaker connections is whenpowered speakers are employed. These speakers containinternal amplifiers and speaker wiring, and are thereforeconsidered a line-level device for which a standard, balancedXLR microphone cable is perfectly suited.What is an XLR used for?
XLR cables are used in audio applications rangingfrom live shows to professional recording sessions. XLRcables have three pins and a circular connector. They are used todeliver balanced microphone and line-level signals over longdistances, so an XLR cable can be simply thought of as amicrophone cable.What are balanced interconnects?
Balanced interconnects use a three-wire system asopposed to unbalanced (RCA) which is a two-wire system (signal andreturn/ground wire). The other two wires in a balanced cableboth carry signal.Are microphone cables balanced or unbalanced?
TRS is a balanced connector type while TS isunbalanced connector type. TRS audio cables are greatfor mono balanced signals, but also stereo signals. The trueexample of a mono balanced signal use for that would be theline in or out from your audio interface which can be amicrophone.What does TRS mean in audio?
Tip, Ring, andSleeve
What is tip ring sleeve?
The three sections of the shaft are called thetip, the ring, and sleeve (a“standard” 1/4″ connector just has a tipand a sleeve). TRS connectors are used wherever it isdesired to have two conductors plus a ground (shield) in oneplug.What is a balanced amplifier?
Balanced means simply that each phase (voltagereference) of a signal has an equal impedance to ground. This canbe accomplished with a single ended amplifier with atransformer on the output; it does not require multiple amplifyingdevices (though multiple devices are used in somecases).
