Optical Splitter 1x3 for SPDIF/Toslink

The J-Tech Digital JTDAT5CH takes a single optical fibre input and distributes it to three SPDIF or Toslink receivers. It handles Dolby Digital and DTS 5.1 surround sound as well as PCM stereo at 32, 44.1, 48 and 96 kHz. Setup is plug and play with no configuration required.

Sustained signal integrity over distance

Optical fibre cable loss is rated below 0.2 dB per metre, allowing clean transmission up to 130 ft. The unit includes over-voltage protection to guard against damage from mismatched power adapters. Signal retiming helps maintain timing accuracy during continuous operation.

Upgrade from single-output source devices

This splitter replaces the need to swap cables when feeding one source into multiple soundbars, AV receivers or recording interfaces. The jump is worth it when a DVD player, console or streamer must drive three zones simultaneously without quality loss. Buyers who need more than three outputs or analogue conversion should look elsewhere.

Questions about this item

Does the JTDAT5CH run hot or draw much power when it splits a signal all day?

The splitter has no fan and consumes very little power; it stays cool during continuous use because it only retimes and distributes the optical signal.

What cables and source gear do I need before the JTDAT5CH will pass audio to three zones?

You need one Toslink cable from a source such as a DVD player into the single input, plus three Toslink cables running from the outputs to each receiving device.

Will the JTDAT5CH work with my older AV receiver that only accepts PCM stereo at 48 kHz?

Yes — the splitter passes PCM stereo at 32 kHz, 44.1 kHz, 48 kHz and 96 kHz untouched, so a legacy 48 kHz-only receiver will receive a compatible stream.
