🎚️🔌 1/4" • XLR Audio Adapter

These adapters convert 1/4" plugs into XLR connectors, enabling signal flow between devices with different audio standards. TRS versions support balanced audio for clean, noise-resistant transmission, while TS versions carry unbalanced signals for instruments and legacy gear.
 
🔧 Adapter Variants & Use Cases
🔌 1/4" TRS Stereo Male → XLR Male
Use Case: Send balanced line-level signal from mixer/interface to XLR input
Devices: Audio interface → powered speaker, or mixer → XLR patch bay
Ideal for clean signal routing with minimal interference
🔌 1/4" TRS Stereo Male → XLR Female
Use Case: Connect balanced 1/4" output to microphone-level XLR input
Devices: Mic output → Mixer input
Common in field recording and live sound setups
🔌 1/4" TS Mono Male → XLR Male
Use Case: Send unbalanced instrument-level signal to XLR input
Devices: Guitar → XLR DI box, or keyboard → mixer
Used when balanced routing isn’t required
🔌 1/4" TS Mono Male → XLR Female
Use Case: Connect unbalanced 1/4" output to XLR mic input
Devices: Mic output → Synth input
Useful in budget setups or legacy gear integration
 
🖥️ Compatible Devices
🎤 Microphones, mixers, and audio interfaces
🎹 Keyboards, synthesizers, and instruments
🎧 Headphone amps and monitor controllers
📼 Field recorders, cameras, and broadcast gear
🛠️ Patch bays, DI boxes, and signal processors
 
✅ Common Uses
🧠 Connect balanced TRS outputs to XLR inputs for clean audio
🎚️ Adapt unbalanced TS instruments to XLR-based systems
🛠️ Bridge studio gear with mismatched connector formats
🔁 Extend cable runs using XLR infrastructure
🧪 Test signal paths between 1/4" and XLR endpoints
 
🧠 Signal Format Notes
⚙️ TRS: Tip-Ring-Sleeve = balanced audio (hot, cold, ground)
⚙️ TS: Tip-Sleeve = unbalanced audio (hot, ground)
⚙️ XLR: 3-pin balanced (pin 1 ground, pin 2 hot, pin 3 cold)
📡 Balanced = better noise rejection over long runs
📉 TS adapters may introduce hum or interference in noisy environments
 
⚠️ Things to Watch Out For
🚫 TRS ≠ TS—don’t mix formats without checking signal type
🔌 Adapter direction matters—match male/female ends to cable and port
🧯 XLR inputs may expect mic-level signals—line-level TRS may clip
📉 TS to XLR may not support phantom power—avoid with condenser mics
🧪 Always test adapters before live use—some are wired differently
 
🛠️ Quick Tips for Beginners
🧠 Identify TRS by two black rings; TS by one ring
🔍 Use balanced TRS → XLR for long cable runs
🧲 Choose metal-bodied adapters for durability and shielding
🧼 Clean contacts gently—dust can cause crackling or dropouts
🏷️ Label adapters by format and direction—especially in live rigs
