⚠️ Important Notice: 1-to-2 Signal Duplication Only & No Mixing Function

1. Stereo Audio Duplication (1 In to 2 Out): This Y-splitter cable is designed strictly to duplicate one 6.35mm (1/4") TRS stereo audio output into two identical stereo signals (e.g., sharing an amplifier or mixing console headphone output between two pairs of headphones or two monitors).
2. Cannot Mix Two Signals into One (Not a Mixer): This is a passive parallel cable and CANNOT combine two audio sources into a single input (e.g., plugging two electric guitars into one amplifier). Combining active audio outputs without a proper resistive mixer can cause signal clipping, impedance conflicts, and potential hardware damage.
3. Not a Stereo Left/Right Channel Breakout Cable: Both female jacks output identical dual-channel stereo signals. It does not split stereo into separate left and right mono channels.
4. Instrument Mono (TS) Note: When used with standard mono electric guitars or bass instruments (TS plugs), the single mono signal is mirrored to both outputs. It does not synthesize true multi-channel stereo effects.

Product Overview

Seamlessly expand your studio listening setup or stage monitoring with this professional 6.35mm (1/4 inch) TRS stereo Y-splitter cable. Engineered with a durable molded 1/4" male jack branching out to dual 1/4" female jacks across a 30cm (11.8-inch) flexible cord, this adapter allows two listeners to monitor the exact same high-fidelity stereo mix simultaneously. Whether sharing a headphone cue from an audio interface, splitting signals to dual studio monitors, or routing keyboard audio to two amplifiers, it ensures zero signal drop and crystal-clear acoustic fidelity.

Key Features

• 1-to-2 Stereo Signal Duplication: Clones any 1/4" stereo headphone or line-level output into two identical stereo feeds for collaborative monitoring and playback.
• Corrosion-Resistant Gold-Plated Contacts: Precision 24K gold-plated TRS connectors ensure maximum electrical conductivity, seamless mating, and long-lasting oxidation resistance.
• Oxygen-Free Copper (OFC) Core: High-grade OFC conductor wire minimizes signal resistance and prevents audio hum, buzz, and radio frequency interference.
• High-Flexibility Molded Strain Relief: Heavy-duty PVC jacket with integrated injection-molded strain relief withstands rigorous studio bending, pulling, and stage use.
• True Plug and Play: Passive design requires no software, external power, or battery—just connect your standard 1/4" audio cables for immediate stereo playback.

Device Compatibility

• Source Output Devices (1/4" TRS Male): Stereo headphone jacks on guitar amplifiers, audio mixing consoles, digital pianos, music keyboards, audio interfaces, DACs, AV receivers, and studio monitors.
• Receiving Devices (Dual 1/4" TRS Female): Studio monitor headphones, secondary amplifiers, stereo sound systems, external speaker monitors, and recording equipment (compatibility list is not exhaustive).
• Non-Compatible Applications: Combining two microphones, mixing two electric guitars into one input jack, or splitting unbalanced TRS into separate left/right TS feeds.

Common Daily Applications

• Dual Headphone Studio Monitoring: Allow a recording engineer and an artist to listen to the same stereo mix simultaneously without an external headphone amp.
• Stage & Rehearsal Split: Send a keyboard's stereo headphone feed simultaneously to personal in-ear monitors and a stage monitor amplifier.
• Music Education & Training: Connect two sets of professional 1/4" headphones to a digital piano or synthesizer for silent teacher-student lessons.

Frequently Asked Questions

Q: Can I use this Y cable to plug two guitars into a single amplifier input?
A: No. This cable is designed exclusively for duplicating one output into two destinations. It cannot combine or mix two audio sources into one input. Connecting two active instrument outputs together directly can cause severe signal distortion and electrical conflicts.

Q: Does this cable separate stereo sound into independent Left and Right mono channels?
A: No. Both female ports receive the full stereo (Left + Right) signal duplicated identically from the male plug. It is not an L/R breakout cable.

Q: Will connecting two pairs of headphones reduce the audio volume?
A: Because this is a passive audio splitter sharing the output power of the host source jack, connecting two pairs of headphones simultaneously may slightly reduce listening volume depending on the headphones' combined impedance. Increasing the master output volume slightly will achieve the desired listening level.
