TS vs TRS Cables (Differences Explained Simply)

• Can TS cables damage your audio gear?
• Learn the key differences between TS and TRS cables.
• Discover potential issues in using them interchangeably with our in-depth guide.

Understanding the differences between TS and TRS cables as a musician or audio enthusiast is essential. While seemingly identical in appearance, they have significantly different applications and can lead to less-than-ideal scenarios used in the wrong instance.

Each connector type is designed to carry a specific signal. For example, using a TS cable will cause noise and distortion when used instead of a TRS cable.

To cover it briefly, it can be summarised as so:

A TS cable has two conductors for unbalanced mono signals, while a TRS cable has three conductors for balanced mono signals or stereo signals.

Guitar cables are classic examples of TS, while TRS cables include balanced audio and headphone cables.

This guide will demonstrate what makes them different, use cases, and what they are designed for.

TS vs TRS Cables (Which Do You Need?)

The question of TS vs. TRS concerns whether you need a balanced or unbalanced signal. You can refer to the below table for a deeper look:

If you are looking for a guitar cable, your best bet is to get TS cable connectors. Typically, guitars output a mono signal, so even if you connect it to a TRS cable, it won’t necessarily lower your risk of interference.
TS cables are longer and easier to use if you’re playing your guitar on a stage. Ensure your guitar cables are never longer than 20 feet to prevent noise.

If your audio equipment requires a balanced or stereo signal, you must use TRS. TS cables can only output mono, unbalanced signals.

You should always check what kind of connector your device needs in the product manual. Many audio interfaces will also indicate what to plug in for the input, output, etc. However, in most cases, you’ll know immediately if you have the wrong cable—the jack won’t fit!

What Is A TS Cable?

A TS cable has two contact points: the Tip (T) and the Sleeve (S). The signal wire sends audio through the tip. The ground wire, which shields the signal from interference, passes through the sleeve.

TS cables are often used for instruments like electric guitars, guitar effects patch cables, keyboards, and single-switch amp A/B boxes.

They are called mono cables because they can only send one signal. So, if you want to use TS cables for stereo audio, you’ll need two cables.

TS cables are unbalanced. That means the audio signal is sent directly to whatever equipment it’s connected to, whether it’s a mixer, receiver, or musical instrument. While it’s simpler (and cheaper), it also means there’s a distortion and noise risk.

The longer your TS cables are, the more likely you are to run into issues with noise and interference. To avoid this, make sure that they are shorter than 20 feet.

What Is A TRS Cable?

TRS cables have three contact points: tip (T), ring (R), and sleeve (S).  That extra contact point makes a big difference because it enables a balanced audio signal. That’s why these are also called “balanced cables” or “balanced TRS”.

The tip has a positive wire, and the ring has a negative wire. When the audio signal passes through, both the wires gather any noise and interference. But since they have opposite polarities, the noise is canceled out. This helps produce a clean and pure audio signal.

Unlike TS cables, the TRS cable can be used with mono and stereo signals. So, it can be used with headphones or any equipment that requires balanced connections. It’s also safer to use TRS cables when you need to plug equipment into multiple devices. It can work with mono-balanced, unbalanced mono, etc. That can eliminate most guesswork over which connectors to use on the right channel.

What About TRRS Cables?

Aside from TS and TRS cables, you’ll also run into TRRS cables, which have a Tip (T), two rings (R ), and a sleeve. They follow the same principle as the other tip ring cables, with the difference being that they offer more channels.

These connectors have four conductors and are commonly used for smartphones, tablets, and computers. That’s because that extra channel allows you to use a microphone or mono balanced with video—essential for any multi-media device!

TRS cables can be used with a TRRS socket. The two often have overlapping standards, and your gadget will usually adjust to a TRS cable by shutting off its internal speaker. That’s why you can still converse on your phone, even using a stereo headset.

In instances when TRS cables don’t fit with your TRRS devices (or the more recent TRRRS, and endless variations of the tip ring sleeve) you can use an adaptor. Adaptors can fit over both TS and TRS connectors to work across all types of audio interfaces. Just remember that only a balanced cable can do stereo.

TS and TRS Troubleshooting

Even after plugging in your connector,  you still don’t hear any sound. Here’s what you need to check:

1. First, ensure your cable isn’t broken. Try taking it out and reinserting it or swapping it for a different cable.
2. You used the wrong cable. You may have used an unbalanced TS instead of a TRS connector. Double-check your product manual. To avoid this problem, label your line input and output so you know what connector to use.
3. You plugged it in the wrong place. You may have inserted an input cable into an output cable.
4. There’s a problem with the position. If two unbalanced cables TS are parallel, they can create a hum in the channel. Try placing them in a perpendicular position.

However, nine times out of 10, the problem lies in using the wrong connectors. As long as you get the right cables, you’ll get the desired results.
