Troubleshooting
No indicator lights are lit and the display is blank.
Check the power lead is securely plugged into the back of the
DD540. Check the power adaptor is plugged into a working,
powered wall socket.
The DD540 is on. It responses to the buttons on its front panel,
but there is no response from the remote control.
Ensure you are pointing the remote control’s infrared transmitter
squarely at the front of the DD540. Check there is nothing
obscuring the display of the DD540. Check the batteries in the
remote control are installed correctly; replace them with new
ones if required.
The DD540 is on but there is no sound heard from the AV
amplifier.
Check the digital audio source is operating.
Check the correct input is selected on the DD540. Check the
correct input is selected on the AV amplifier.
Check that the cable connections between the source and the
DD540, and between the DD540 and the AV amplifier, are
secure. Try alternative cables that are known to be working.
Check the DD540’s output configuration is correct for the cable
connections in place. Refer to
Typical Connections
on page 8
and also
Output Configuration
on page 14.
Does the digital audio signal from the source have a sample rate
of more than 96kHz? The DD540 can handle up to 96kHz. If the
frequency is higher, reduce the sample rate of the source.
If there is still no remedy after the above approaches, try this
test: Disconnect the source from the DD540. Disconnect the AV
amplifier from the DD540. Connect the source to the AV
amplifier directly using the same sockets that were used with the
DD540. If there is no sound, the issue is with the source or AV
amplifier. Refer to their documentation for more information.
