TRS Cables

What is a TRS Cable?

TRS vs. TS: Why Does It Matter?

A TS (Tip-Sleeve) cable only has two conductors and is primarily used for mono instrument signals like electric guitars. In contrast, a TRS cable features a third conductor, allowing it to function for:

• Balanced connections, reducing unwanted noise and interference
• Stereo audio transmission, separating left and right channels
• Insert cables, splitting audio signals for effects loops and processing

Using a TS cable where a TRS is required can result in loss of signal quality, improper grounding, or a non-functional connection.

Are TRS Cables Balanced?

A common misconception is that TRS cables are inherently balanced, but the truth is that the interface determines whether a connection is balanced or unbalanced. To achieve a true balanced connection, both devices must support it, ensuring noise rejection and interference reduction in professional audio systems.

TRS Cable Sizes & Compatibility

TRS cables come in multiple sizes, with the most common being:

• 1/4" (6.35mm) – Standard for pro audio gear, studio monitors, and mixers
• 1/8" (3.5mm) – Used for headphones, smartphones, and portable audio devices
• 3/32" (2.5mm) – Less common, mainly found in older mobile and communication equipment

Before purchasing, verify the correct size for your equipment to ensure compatibility and optimal signal transfer.

Choosing the Right TRS Cable for Your Needs

When selecting a TRS cable, consider:

• Shielding & Build Quality – Higher shielding prevents interference
• Gold-Plated Connectors – Enhanced durability and conductivity
• Cable Length – Longer cables may introduce signal loss if unbalanced

Whether you're setting up a recording studio, live performance rig, or professional broadcast system, high-quality TRS cables ensure reliable, noise-free audio transmission.
