Learn what a 6.35mm TRS stereo to dual TS mono Y splitter does, when to use it, and how it differs from other audio cables for your studio or live setup.

Quick answer

A 6.35mm TRS to dual TS Y splitter converts a single stereo signal into two separate mono signals, or splits a mono signal to feed two destinations. It is commonly used with mixers, audio interfaces, and amplifiers.

When you need a stereo-to-mono splitter vs. a simple Y cable

Many Y cables simply duplicate a signal without changing its wiring. A TRS-to-dual-TS splitter specifically breaks a stereo (tip-ring-sleeve) connection into two mono (tip-sleeve) connections. This matters when your source outputs stereo but your destination expects two separate mono inputs, such as sending a headphone output to two mixer channels.

If you only need to send one mono signal to two devices, a standard TS Y splitter may work, but the TRS-to-dual-TS design ensures correct channel separation and avoids phase issues.

Common use cases in a live or studio setup

In a recording studio, you might use this cable to route a stereo keyboard output into two mono channels on a mixer for independent EQ and panning. On stage, it can split a mono instrument signal to feed both an amplifier and a direct box for the front-of-house system.

The right-angle connectors on models like the 6.35mm TRS Stereo to Dual 6.35mm TS Mono Right Angle Y Splitter help keep cable runs tidy behind gear racks or pedalboards.

Frequently asked questions

Can I use a TRS-to-dual-TS cable to connect a stereo headphone output to two mono speakers?: Yes. The TRS plug carries left and right audio on the tip and ring, and the two TS plugs output those as separate mono signals. This works for powered monitors or amplifier channels that accept TS inputs.
Will this cable work for splitting a guitar signal to two amps?: It can, but note that a TRS-to-dual-TS cable is wired for stereo splitting. For splitting a mono instrument signal (like a guitar) to two amplifiers, a standard TS Y splitter is usually simpler and avoids potential grounding issues. If you only need to duplicate a mono signal, a TS Y splitter is often the better choice.
Does the right-angle plug affect audio quality?: No. The right-angle design is purely mechanical; it does not alter the electrical signal. It simply allows the cable to fit in tight spaces and reduces strain on the connector.
What length should I choose for my setup?: Consider the distance between your source and destination. Shorter lengths (1-3 ft) keep cable clutter low on a desktop or pedalboard, while longer lengths (6-10 ft) give flexibility for stage or studio routing. The featured cable is available in multiple length options. Measure your signal path before ordering to avoid excess cable or tension.
