TS vs TRS Cables – What’s the Difference?


A ‘TS’ cable stands for ‘Tip Sleeve’ and is generally used for mono and unbalanced signals such as a guitar or bass. Whereas, a ‘TRS’ cable is short for ‘Tip Ring Sleeve’ and can be used for balanced mono as well as stereo signals. 

If you have been to a recording studio or observed the sound desk at a music festival, you may have observed various types of cables with different heads. While a standard TS and TRS cable may appear similar at first glance, they have very different purposes and the circuitry is completely different.

Read on to find out what exactly are TS and TRS cables and when to use them:

What’s The Difference Between a TS and a TRS Cable?

  • A TS cable is used for unbalanced audio signals whereas a TRS cable can be used for a balanced or an unbalanced signal.
  • A TS cable is used for mono signals and a TRS cable is used for either mono or stereo signals.
  • TRS cables have lower noise interference than TS cables.
  • TS cables carry one audio signal through a single connector. This is why they are also known as ‘mono’ cables. Unofficially, they are also referred to as ‘instrument’ cables. 
  • TS cables cannot transmit balanced audio since they have only one conductor, located at the end. This is known as the “tip”. 
  • TRS cables are often referred to as “headphone” cables since they can have two (stereo) audio signals.
  • Good quality TRS cables are generally more expensive than TS cables. 

What Are TS Cables Used For?

TS cables are used to connect instruments such as guitar, bass, or even microphone to an amplifier. Guitar pedals and footswitches, loudspeaker outputs, line outputs, and even electronic keyboards need TS cables to connect them to sound output. 

Historically, TS cables were used by telephone operators when connecting calls between people. This is why they are still called “phone” jacks or cables by many people today.

The connector of a TS cable is 6.35mm (¼ inch) in size. It is a two contact plug where the tip is insulated from its adjacent body and sleeve.. 

TS outputs can be found on audio interfaces and need TS cables for you to connect the interface to a speaker or any other audio output device.

TS cables are also used for many different Euroracks, Moog synthesizers, and other modular synthesizers. 

What Are TRS Cables Used For?

TRS cables are used for devices such as microphones, headphones, and even mixing desks.

In some devices such as camcorders and portable DVD players, a TRS connection is required for mono audio and video together. LCD monitors will built-in speakers generally require a 3.5mm male TRS to connect to an audio interface.

Interestingly, TRS cables are also used in home security systems. They provide protection from  power surges and radio frequency interference. 

Is Guitar A TRS Or TS?

A guitar has a TS output and thus, TS.

Although TS cables often have noise interference because they are unbalanced, most instruments and audio units still require them. This is because switching to balanced cables would require additional complex components and the process would be expensive. This would thus potentially increase the price of instruments even more. Hence, even though balanced outputs are a great idea they are impractical to implement.

Since TS cables are shielded, they do not produce an unmanageable amount of noise. Good quality cables not only last for a long period of time but also have minimal interference. If you have been using high-quality cables and still experiencing issues, then you should look into your amp because that could be the main culprit. 

Why Don’t Guitars Use Balanced Cables?

Guitars don’t use balanced cables because this would require changing the standard circuitry, output jack, and additional components. This would make it an expensive process and hence not much research has gone into output jacks that require balanced cables to produce sound.

Humbucker pickups were created for electric guitars to cancel the sound produced by single-coil pickups. Thus, guitars today do not produce large amounts of unwanted noise interference even though they use unbalanced cables.

Professional guitar players who use many different guitar pedals will often plug their pedalboard into a DI (Direct Injection) box that is connected to their guitar. A DI box converts an unbalanced signal into a more usable one. This is a much cheaper alternative to changing the guitar’s circuitry. 

TRS cables are better suited for instruments such as microphones which produce a high interference. They require a balanced output which can then go into a mixing desk or an audio interface.

Will A TRS Cable Work As A Guitar Cable?

Yes, a TRS cable will work as a guitar cable but it will still not conduct a balanced signal.

This is because even when you plug a balanced TRS cable into your guitar, the guitar is capable of producing only an unbalanced signal. 

So if you are planning to use a TRS cable to get rid of noise, this method will not work. However, in an emergency when you don’t have a TS cable, a TRS can work as a replacement. 

While there is a slim chance of damage to the amp or the guitar when using a TRS cable, one may have connection issues. You need to ensure that the parts of the connector are touching the correct parts within the circuit.

Are TRS Cables Shielded?

Yes. TRS cables are shielded.

In addition to two conductors, TRS cables also have a shield. This shield creates a Faraday cage which reduces electrical noise from affecting the signal. The shield also prevents electromagnetic radiation from affecting other devices surrounding it. 

If you have a frayed TRS cable lying around or one that no longer works, you can open it up to see the shield covering the conductor when you take it out of the jacket. 

How Do You Know If A Cable Is TS Or TRS?

It is sometimes easy to get confused between a TS and a TRS cable because they can look quite similar.

One of the major differences between the two is that a TRS cable will have an additional ring around the tip sleeve. Since there are two conductors (and a shield) in a TRS cable, there are two rings.

A TS cable, on the other hand, has one ring. 

Summary

Both TS and TRS cables can be of different sizes. Some of the common ones are ¼” and ⅛”. While a TS cable only processed unbalanced and mono audio, a TRS cable is capable of balanced audio in both mono or stereo format.

This is why your audio interface has many different options for output whereas your guitar has only one. 

Although many advancements have been made in the field of technology, musical equipment follows a global standard. Uprooting this system would not only be expensive but can also create a whole lot of unnecessary troubles when recording a song or even performing live.
