18) SPDIF_IO (SPDIF In / Out Connector)
The SPDIF output is capable of providing digital audio to external speakers or compressed AC3
data to an external Dolby Digital Decoder. Use this feature only when your stereo system has
digital input function. Be careful with the polarity of the SPDIF_IO connector. Check the pin
assignment carefully while you connect the SPDIF_IO cable, incorrect connection between the
cable and connector will make the device unable to work or even damage it. For optional
SPDIF_IO cable, please contact your local dealer.
