Buy this to feed one optical source to three speaker units at once. If you need to choose between several sources into one output, this is the wrong direction of box.

Overview
A buyer with one optical source and several speaker units gets a small box that duplicates that signal. Signal enters on a single TOSLINK input and leaves on three outputs that carry the same audio, so every connected unit plays the same thing at the same time. Inside, integrated circuits copy the stream instead of a mechanical split, and the included adapter supplies power.
Feeding several speaker units from one optical output is the job here, and the duplication happens electronically so the three outputs stay identical to the input. The limitation is directional: it cannot select between sources, and it is not the three input to one output switch that looks similar. Check the model number before ordering.
Who it's for
Rooms where a single digital audio source has to reach more than one speaker unit at the same time. The box does nothing for anyone who needs source switching, and it will not help a setup with only one destination.
Pros and cons
- Duplicates one optical input to three outputs
- Handles Dolby Digital and DTS surround signals
- Supports PCM stereo at rates up to 192kHz
- Circuit based splitting, no mechanical parts
- Cannot switch between multiple inputs
- Optical cable not included
- No surround format beyond Dolby Digital and DTS 5.1 listed
Performance notes
The result depends on the source format and the receiving units: a stream the connected speakers can decode passes through, while anything outside the listed formats will not. Because the copies are made electronically, output level and timing stay matched across the three ports.

Frequently asked questions
What do I need to set up the ViewHD VHD-TS1X3?
The box, the included power adapter and your own optical cables. The listing includes the splitter, a universal adapter with a US plug and a user manual, and it says nothing about optical cables, so plan on supplying those yourself.
How is this different from the VHD-TS3X1?
The two units look similar but run opposite directions. This model takes one optical input and sends it to three outputs; the other takes three inputs into one output. Check the model number on the box before you order.
Can it split a signal to three speakers at the same time?
Yes. One optical input is duplicated to three outputs, and all three carry the same audio as the input, so the connected units play the same content together.
Which audio formats pass through the splitter?
Dolby Digital and DTS 5.1 are supported, along with PCM stereo at 32, 44.1, 48, 96 and 192kHz. Formats outside that list are not covered by the listing.
Does the splitter need external power?
Yes. It runs from the included DC5V adapter, which accepts 100 to 240V and comes with a US plug, so a nearby outlet is required.
