🔊💡 Optical • Optical Audio Splitter

These splitters take a single optical (Toslink) digital audio input and distribute it to multiple outputs—either 3 or 5—allowing simultaneous playback across soundbars, receivers, DACs, and wireless transmitters. They preserve digital fidelity and are ideal for hybrid AV setups, multi-room audio, and synchronized playback.

Example: Smart TV → soundbar + AV receiver + wireless headphone base
Signal: Digital optical (SPDIF/Toslink)
Audio Formats: PCM, Dolby Digital, DTS
Power: Requires external power (USB or DC barrel)
Note: Maintains signal quality across all outputs
2️⃣ 1x5 Optical Audio Splitter
Use Case: Distribute one optical source to five devices
Example: Blu-ray player → soundbar + receiver + DAC + Bluetooth transmitter + secondary amp
Signal: Digital optical (SPDIF/Toslink)
Audio Formats: PCM, Dolby Digital, DTS, LPCM2.0
Power: Active splitter with dedicated power input
Note: Ideal for full AV rigs or audio testing environments

🧠 Signal Format Notes
Connector Type: Toslink (SPDIF optical)
Signal Type: Digital audio only—no analog passthrough
Audio Support: PCM, Dolby Digital, DTS, LPCM2.0
❗ Does not support Dolby TrueHD or 7.1CH formats

⚠️ Things to Watch Out For
🔌 Requires external power—check voltage and connector type
🔄 All connected devices must support the same audio format
🧯 Not bidirectional—only splits one input to multiple outputs
📏 Use high-quality optical cables to minimize signal loss
🧪 Avoid passive splitters for multi-output setups—active splitters preserve fidelity
 
🛠️ Quick Tips for Beginners
🔍 Look for “active” splitters with power input for best results
🧭 Match audio format across all devices (e.g., PCM or Dolby Digital)
🎧 Use 1x3 for small setups; 1x5 for full AV rigs
🧪 Test each output individually before full deployment
🧩 Label outputs for easy routing and troubleshooting
