🔊🔀 RCA • RCA Splitter

These splitters duplicate or merge RCA signals, allowing one source to feed multiple destinations or combining multiple inputs into one. They’re used in stereo audio setups, subwoofer distribution, and analog video routing. Each format serves a distinct purpose in signal flow and device compatibility.
 
🔧 Splitter Varieties
1️⃣ 1x Male RCA → 2x Female RCA
Use Case: Split one RCA output into two inputs
Example: AV receiver sub-out → two powered subwoofers
Signal: Mono or stereo depending on color-coded channel
Note: Common for duplicating signal to multiple playback devices
2️⃣ 1x Female RCA → 2x Male RCA
Use Case: Merge two RCA outputs into one input
Example: Dual audio sources → single speaker or amp input
Signal: May cause signal blending—use with caution
Note: Not ideal for true mixing—best for passive signal merge
3️⃣ 1x Female RCA → 2x Female RCA
Use Case: Join two male-ended cables into one input
Example: Extend or reroute RCA cables in modular setups
Signal: Passes signal from either cable to single destination
Note: Useful in patch bays or flexible AV routing
 
🖥️ Compatible Devices
📼 DVD players, VCRs, and tape decks
📺 TVs and projectors with RCA inputs
🔊 AV receivers and stereo amplifiers
🎧 Subwoofers and powered speakers
🎮 Game consoles and retro systems
🧪 Audio/video testing rigs and patch panels
 
✅ Common Uses
🔄 Duplicate mono or stereo RCA signal to multiple devices
🎧 Split subwoofer output for dual bass setups
🧩 Merge two RCA sources into one input (with caution)
🛠️ Extend or reroute RCA cables in modular AV environments
🧪 Prototype analog signal paths across legacy gear
 
🧠 Signal Format Notes
RCA Connectors
Red = Right audio
White = Left audio
Yellow = Composite video
Mono vs Stereo
Mono splitters duplicate single-channel signal
Stereo splitters split left/right channels separately
❗ Splitters do not amplify—signal strength may drop slightly
🔄 Passive splitters do not isolate signals—may cause interference
 
⚠️ Things to Watch Out For
🔌 Merging signals (2→1) can cause distortion or impedance mismatch
🧯 Not suitable for mixing—only passive duplication or merge
📏 Use short, shielded cables to minimize signal loss
🔄 Match color-coded channels to avoid phase or channel swap
🧪 Test signal integrity before live or critical use
 
🛠️ Quick Tips for Beginners
🔍 Identify connector gender before buying (male vs female)
🧭 Use 1xM→2xF for splitting; 1xF→2xM for merging
🎧 Label channels clearly in stereo setups
🧪 Test with known mono/stereo source to confirm routing
🧩 Keep a mix of splitter types in your AV toolkit
