As a musician, understanding the different types of audio cables is essential to achieving high-quality sound. Three common types of audio cables are TS, TRS, and TRRS cables. These cables differ in their connector design, the number of conductors, and their application. In this article, we will explore the differences between TS, TRS, and TRRS cables, their common uses, and how they affect audio quality.
TS Cables: The Basics
A TS (Tip-Sleeve) cable is the simplest type of audio cable. It has a single conductor that carries an unbalanced signal. TS cables are commonly used for instruments such as electric guitars, keyboards, and microphones that have an unbalanced output. They can be found with 1/4 inch and 3.5mm jacks.
TRS Cables: Balanced Audio and Stereo Sound
A TRS (Tip-Ring-Sleeve) cable has two conductors, plus a ground wire. TRS cables can carry either a balanced or unbalanced signal, depending on the equipment used. Balanced signals are commonly used in professional audio setups to minimize noise and interference.
TRS cables are often used for headphones, studio monitors, and other professional audio equipment that requires a balanced connection. 1/4 inch TRS jacks are commonly found in the studio, while 3.5mm TRS jacks are commonly found on portable devices.
Understanding the stereo field is also important when working with TS and TRS cables. TS cables are used for mono signals, while TRS cables can be used for both mono and stereo signals. When used for stereo signals, the left channel is transmitted through the tip conductor, and the right channel is transmitted through the ring conductor.
TRRS Cables: Audio and Microphone Integration
A TRRS (Tip-Ring-Ring-Sleeve) cable has three conductors plus a ground wire. TRRS cables are commonly used for smartphones and other mobile devices, allowing you to transmit audio and microphone signals over the same cable. The 3.5mm TRRS jack is most commonly used for these applications.
PRO TIP: Is the sound not working on your interface through your headphones? Are using a 3.5mm to 1/4" adapter for your headphones and is your headphone cable a TRRS? Chances are that the adapter you're using might not be compatible with your TRRS headphones. A different adapter solved the problem for us. Now, we have two 3.5mm to 1/4" adapters; one for TRS (3.5mm) to TRS (1/4") and one for TRRS (3.5mm) to TRS (1/4"). This is exactly why understanding how your cables work will help you diagnose issues faster so you can get back to what really matters; making music.
Balanced Signals: The Key to Noise-Free Audio
Balanced signals, which are commonly used with TRS cables, are designed to cancel out noise and interference. This is achieved by using two conductors carrying the same signal, but with opposite polarity. This is known as a differential signal.
When the signal reaches the receiver, the inverted signal is flipped back to its original polarity and combined with the original signal, canceling out any noise or interference that was picked up along the way. This is particularly important in live performances, where cables can pick up electromagnetic interference from lighting and other equipment.
Understanding the differences between TS, TRS, and TRRS audio cables is essential for musicians and audio professionals looking to achieve the best possible sound quality. By recognizing the appropriate applications for each type of cable, you can ensure a reliable and high-quality audio experience in both live performances and studio recordings.
