GND terminal.
A DTS-CD is being played back.
The record is being played on a turntable
with an MC cartridge.

Remedy

Set the playback component properly referring to its
instruction manuals.

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."
Connect your turntable to this unit through an MC-
head amplifier.
When the component connected to the output jacks of
this unit is not turned on, the sound may be distorted
or the volume may decrease due to the nature of AV
receivers. Turn on all components connected to this
unit.
Set it to a higher value.
Remedy
Disconnect some of the HDMI components.
