Your TV has a Toslink output, but you are using two amplifiers. Therefore, the Toslink cable needs to be split from one to two. An additional amplifier could be a surround system, a soundbar, or an amplifier in the kitchen, for example. Very practical for home use or for professional audio distribution. With an improved 192 kHz sampling rate for the best sound reproduction. Supports the S/PDIF and Toslink standards. Supports uncompressed two-channel LPCM (Linear Pulse Code Modulation) audio signals. Supports compressed two-channel and multi-channel Dolby Digital and DTS audio signals.
