Set "Bass Out" to "Both."
Set "EXTD Surround" other than "Off" or "Auto."
Set the playback component properly referring to its
operating instructions.
Connect the audio cables properly. If the problem
persists, the cables may be defective.
1) When only noise is output
If a DTS bitstream signal is not properly input to this
unit, only noise is output. Connect the playback
component to this unit by digital connection and play
back the DTS-CD. If the condition is not improved,
the problem may results from the playback
component. Consult the manufacturer of the playback
component.
2) When noise is output during playback or skip
operation
Before playing back the DTS-CD, display the option
menu after selecting the input source and set
"Decoder Mode" to "DTS."
Set "Memory Guard" to "Off."
Disconnect the power cable from the AC wall outlet,
wait about 30 seconds and then plug it in again.
Make sure all speaker cables are connected correctly.
Move this unit further away from such equipment.
