My surround speakers connecting to the optical port are not working?

  • Products Affected

The Digital Optical Audio (S/PDIF) port on the TS3 Plus supports “Pass-Through” method to the surround sound speaker system which has a standalone 5.1 channels receiver/decoder. For example, the Logitech Z906 speaker system. This can enable audio files or videos with AC3 format to be sent from the TS3 Plus to the speaker’s receiver through optical connection.

If you have any problem to output surround sound through TS3 Plus’ S/PDIF port, please contact CalDigit’s regional support team and provide your setup.
