Ⅵ: Failure Check

1. No sound output
 A. Check whether the power 5.1 AUDIO DECODER power is on or not.

 B. Check whether the input channels and output connections on the same channel (please use "S 'key to change, OPT1 --- D1 lights, OPT2-D2 lights, COX --- D3 lights)

C. Make sure the output device (PS3/XBOX360/DVD Player / HD Player) is set to digital audio output.

D. Make sure the 5.1 amplifier power on， and switch to the 5.1 audio input, turn on the volume.  

If connect 5.1 headphones, make sure connect USB-power access, and turn on the volume.

2. Noise
A. Make sure the cable is good

B. Are there unusual audio input

C. Check this noise is weather from 5.1 amplifier or headphones.
