📼🔌 Composite RCA • Composite RCA Cable
Composite RCA cables transmit analog signals using color-coded connectors. They’re used for video, mono/stereo audio, and AV combinations across legacy devices. Each variant serves a specific role in signal routing, with male/male cables for direct connections and male/female cables for extensions or gender swaps.
🔧 Cable Varieties
1️⃣ 1RCA Cable
- Single-channel analog signal
- Typically yellow (video), white (mono audio), or black (subwoofer)
- Used for composite video, mono audio, or digital coaxial audio
- Available in male/male and male/female formats
- Common in CCTV, DVD players, and subwoofer setups
2️⃣ 2RCA Cable
- Stereo analog audio
- Red = Right channel, White = Left channel
- Used for connecting CD players, turntables, TVs, and amplifiers
- Male/male for direct audio links; male/female for extending stereo cables
- Also used in Y-splitters and stereo patching
3️⃣ 3RCA Cable
- Composite video + stereo audio
- Yellow = Video, Red = Right audio, White = Left audio
- Standard AV cable for DVD players, game consoles, and VCRs
- Male/male for full AV connection; male/female for extending AV runs
- Often bundled with older devices or used in AV switchers

🧠 Signal Format Notes
- RCA = Unbalanced analog signal
- 1RCA = Composite video, mono audio, or digital coaxial
- 2RCA = Stereo analog audio
- 3RCA = Composite video + stereo audio
- ❗ No signal conversion—just transmission
- 🧲 Color coding helps prevent miswiring
⚠️ Things to Watch Out For
- 🚫 RCA is not compatible with HDMI, VGA, or optical without conversion
- 🔄 Match colors and channels—miswiring causes signal loss or distortion
- 📏 Cable length affects signal quality—use shielded cables for longer runs
- 🧯 Male/female cables are for extension, not signal conversion
- 🧪 Avoid using audio RCA cables for video—they may lack proper shielding
🛠️ Quick Tips for Beginners
- 🔍 Yellow = video, Red = right audio, White = left audio
- 🧭 Use male/male for direct device-to-device links
- 🧰 Use male/female to extend or adapt cable ends
- 🧪 Test signal before permanent install—especially with long runs
- 🎮 For retro gaming, 3RCA cables are essential for authentic AV output
