Troubleshooting

No “Source” indicated - Is the 132k upsampling feature on?  Is the balanced input
active?  Both can result in no source LED lit.  Next, check for bad cable, or cable
plugged into the wrong output on the transport.

No sound - Check that source is valid audio source.  Change to a standard CD just
to be sure.  Check that analog outputs are connected to the “outputs” not the
“inputs”.

Still no sound - connect an analog output from the source directly to the volume
control.  Verify that the rest of the system is working.  Now move the same analog
output to the analog input on the LINK.  Add a new cable from the analog output to
the volume control.  Disconnect the digital inputs and confirm that the system still
works.  Now plug in a digital source.  You should hear a click and the front LEDs
should light.

96K source indicates 48k on front panel - Check setup menu of DVD player.  Digital
output should be set for 96k output.  Some models do not support this feature.

DVD-A source indicates 48k - DVD-A players must be upgraded to provide a true
192K output.  Production players downmix to 48K.

Balanced Input not working - Check configurations - is XLR  connector plugged

into balanced or 192k input.
