BlueRigger Toslink Optical Audio Splitter 1-in-3

BlueRigger's active Toslink audio splitter converts a single optical SPDIF output into three independent fiber-optic outputs for sharing one digital source with multiple devices.

If you need to feed the same digital audio signal from a TV, game console, or Blu-ray player to several receivers, soundbars, or Bluetooth transmitters at once, this compact, powered splitter simplifies the setup. The unit uses an aluminum-alloy housing and low-loss fiber components to reduce signal degradation and supports common stereo and surround formats used by home theater equipment.

How many devices can I connect at once and what equipment do I need?

The BlueRigger splitter accepts one Toslink optical input and provides three optical outputs so you can route audio to up to three receiving devices simultaneously. It requires the included USB power cable to operate; a USB power source is needed (USB wall adapter not included).

• 1 optical input (Toslink) to 3 optical outputs
• Includes USB power cable — plug into a TV USB port or USB power adapter
• USB AC adapter is not supplied; use a standard 5V USB adapter

Which audio formats and channels does this splitter support?

This active splitter handles SPDIF digital audio formats commonly used in home AV setups, including LPCM and Dolby Digital/DTS up to 5.1 channels. It does not transmit 7.1-channel formats such as Dolby TrueHD or Dolby Digital Plus over Toslink fiber.

• Supports Dolby AC3 (5.1), DTS, PCM, LPCM2.0, ADAT
• Frequency compatibility: 32 kHz, 44.1 kHz, 48 kHz, 96 kHz
• Not compatible with 7.1CH Dolby TrueHD or Dolby Digital Plus via optical

Will the audio quality suffer when splitting the signal?

The splitter is an active device that regenerates the optical signal before distributing it, which helps preserve signal integrity across all three outputs. Its aluminum shell and precision fiber connectors reduce attenuation and interference compared with passive splitters.

• Active electronics restore and amplify the optical signal
• Aluminum-alloy casing for heat dissipation and durability
• Low-loss fiber core and hardened connector heads minimize errors

How easy is installation and what devices are compatible?

Installation is straightforward: connect your source’s Toslink cable to the input, run up to three Toslink cables to your receivers, and plug the included USB power cable into a 5V USB power source. The splitter works with a wide range of consumer gear commonly found in living-room AV systems.

• Compatible with TVs, Apple TV, cable boxes, Xbox, PS4, CD/DVD/Blu-ray players
• Works with soundbars, AV receivers, Bluetooth transmitters, DACs
• Compact footprint fits on media racks or behind equipment

Who is this for: homeowners, gamers, and small AV installers who need a reliable way to share one optical audio output among multiple devices without re-plugging cables. It’s especially useful for multi-zone listening, connecting both a soundbar and a Bluetooth transmitter, or routing a console’s audio to a receiver and a recording device simultaneously. BlueRigger backs the product with lifetime warranty and U.S.-based support, making it a practical choice for anyone looking to expand optical audio connectivity in a home entertainment setup.
