Dear friend,
Thanks for your message. Sincerely sorry for the inconvenience caused to you! No worry, I'm here to help you.
To use the item, you may need to insert the Optical cable into the toslink port, and connect it to an amplifier. Then you connect the R/L port to your DVD or LED TV. Then you connect the power supply to the wall charger.
If you not mind, could you please kindly try it again?
Thanks for your understanding!
Coco:)
