• Supports HDMI ARC function: Use the ARC button on the front to enable/disable ARC mode; in ARC mode the HDMI ARC audio signal is available from the Toslink optical audio output, ARC audio is not supported by RCA L/R output.  ARC audio typically uses DD5.1CH AC3 format, a Dolby Digital receiver with optical input is needed for ARC application and the TV must have an HDMI ARC input port. Connect the HDMI output port of the UAEP to the HDMI ARC input port of the TV, connect the optical port of the UAEP to the receiver, use the ARC button to enable/disable ARC mode. When the TV is in ARC mode, the TV's own speaker will be disabled.
• UAEP model has three audio EDID settings: "Pass" to use TV's speaker for audio, "2CH" to use RCA L/R stereo analog output, "5.1CH" to use Toslink output with a Dolby Digital surround receiver.
• In the 5.1CH mode setting, if the HDMI source can support Dolby Digital Plus / DD+, then it will use DD+, but if your receiver doesn't support DD+, please manually disable DD+ in the HDMI source. Always check the user manual for details or contact the manufacturer for technical support.
