Signal distribution

This SMUGDESK optical splitter takes a single Toslink input and sends the same digital audio stream to three separate outputs at once. It lets one source — such as a TV, console or media player — feed multiple soundbars, amplifiers or receivers without swapping cables. The unit handles LPCM 2.0, DTS and AC3 formats for multi-channel sound. No driver or software is required, so it works immediately after connection.

Build integration

The splitter sits between your source device and up to three playback units, removing the need for a switch or manual cable changes. Its compact housing fits on a crowded TV shelf or rack without blocking neighbouring ports. Because it is purely passive, it adds no power brick or extra cable to the installation. All three outputs stay active simultaneously, freeing you from choosing which zone hears the audio.

Thermals and power

Passive optical circuitry means the device draws no external power and generates no measurable heat during normal use. There are no fans, so operation is completely silent in any listening environment. The fiber-optic links eliminate ground-loop hum and electromagnetic interference that can affect analogue connections. Signal integrity remains stable across all three outputs without degradation.

Questions about this item

Does the splitter handle LPCM 2.0 without degrading the signal over long listening sessions?

Yes, the unit maintains synchronized output on all three channels with pure digital optical transmission and no audio degradation during distribution.

Will the device stay cool and silent when left running continuously?

The compact housing has no fan or power supply, so it generates no audible noise and remains at ambient temperature during all-day use.

Which cables must I already have to connect my TV and two soundbars?

You need three Toslink optical cables — one from the source to the input and one from each output to the playback devices.
