  • Connect one Toslink source to three devices

Single-source optical splitter

The Monoprice 143391 takes one Toslink S/PDIF input and duplicates the signal to three optical outputs. It is built for users who need to send the same digital audio stream to a television, an AV receiver and a soundbar simultaneously.

96 kHz sampling rate

The splitter handles two-channel high-definition formats including LPCM, DTS and Dolby Digital at a 96kHz sampling rate. It also performs signal re-timing to maintain integrity across the three paths. Sources or sinks that require multichannel audio beyond two channels are not supported.

USB powered with 40 m reach

A USB connection supplies operating power, so no separate mains adapter is needed. Optical cables can run up to 131 feet (40 meters) with loss below .2 dB per metre, giving flexibility for component placement across a room. The unit does not amplify or switch signals; it only splits an existing Toslink feed.

Questions about this item

What does the 96 kHz sampling rate mean for my audio setup?

It means the splitter can pass stereo LPCM, DTS and Dolby Digital streams at up to 96 kHz without down-sampling, so surround sound from a Blu-ray player or game console stays intact across all three outputs.

How far can I run the optical cables from this splitter?

The unit can transmit a clean signal up to 131 feet (40 metres) over standard Toslink cable with loss below .2 dB per metre, so long runs to a distant AV receiver or second zone are practical.

What power connection does the splitter need?

It draws power from a USB port — plug the included micro-USB lead into a TV USB socket, a console port or any 5 V USB charger to keep the splitter running.
