🎛️ 3.5mm • 1/4" Breakout Audio Splitter

This splitter converts a stereo 3.5mm TRS signal into two mono 1/4" TS outputs—typically left and right channels. It’s used to route audio from phones, tablets, or laptops into mixers, recorders, or powered speakers with discrete mono inputs.
 
🔌 Splitter Varieties
🔹 1x 3.5mm Male → 2x 1/4" Male
Form: One 3.5mm stereo plug → Two 1/4" mono plugs
Use Case: Split stereo output from a mobile device into two mono inputs
Examples:
Phone → mixer L/R channels
Laptop → stereo DI box
Tablet → dual powered speakers
Note: Each 1/4" plug carries one channel (Left or Right)

🧠 Signal Format
3.5mm TRS (Tip-Ring-Sleeve):
Tip = Left audio
Ring = Right audio
Sleeve = Ground
1/4" TS (Tip-Sleeve):
Tip = Mono signal (Left or Right)
Sleeve = Ground
Breakout Behavior:
Left channel → one 1/4" plug
Right channel → other 1/4" plug
 
⚠️ Things to Watch Out For
🔄 Not bidirectional — designed for stereo → dual mono only
🧬 TRRS incompatibility — won’t pass mic/control signals
📏 Signal loss — passive splitters may reduce volume
🔊 No stereo summing — each channel stays isolated
🎛️ Impedance mismatch — may affect volume balance
 
🛠️ Quick Tips for Beginners
🔍 Count the black bands: 2 = TRS (stereo), 1 = TS (mono)
🧠 Use for stereo playback into dual mono inputs
⚡ Don’t use to combine two mono outputs into one stereo input
🧰 Label L/R ends to avoid channel confusion
🎛️ Test with headphones or meters before live use
