The sound is poor or distorted.
< Are the cables to the source and to the power amplifier making a good connection? If necessary
withdraw the cable from the connector and plug it back in again (turn the power off before doing
this).
< For analogue audio sources, is the input sensitivity on the ‘Input Trims’ page in the Set-up Menu
reduced excessively? Check that the input is not clipping by using the ‘Analogue Settings’ page.
< Have you selected the correct size of speakers to suit your system? Use the ‘Speaker Sizes’ page
in the Set-up Menu.
Sound comes only from some of the speakers.
< Ensure that you have a surround-sound source selected and playing.
< Ensure that the DVD player has been set to put ‘Bitstream’ or ‘Raw’ audio out on the digital
output.
< Does the display window indicate that the disc you are playing is a multi-channel recording?
< Are all the speakers connected correctly to your power amp., and are the connections secure?
< Have you selected ‘Stereo’ in the mode selection?
< Is your speaker balance correct?
< Are all amplifiers turned on and all channels are working correctly?
< Have you configured your AVP700 to include all the speakers in your system?
Unable to select Dolby Digital or DTS decoding modes.
The AVP700 can apply Dolby Digital or DTS decoding only to sources that have been encoded in
those formats.
< Ensure that a digital source is selected and connected.
< Is the source playing appropriately encoded (Dolby Digital or DTS) material?
< Ensure that the DVD player has been set to put ‘Bitstream’ or ‘Raw’ audio out on the digital
output.
Hum on an analogue input.
< Are the cables to the source and to the power amplifier making a good connection? If necessary
withdraw the cable from the connector and plug it back in again (turn the power off before doing
this).
< Are the connections inside the source cable connector broken or badly soldered?
< If the hum originates only when one particular source component is connected, is an aerial,
cable or dish connection to this source ground isolated? Contact your installation contractor.
If the above items fail to fix the problem, try switching the ground lift switch on the back panel.
There is radio or television reception interference.
Where is the interference is coming from? Switch off each source component in turn, then any other
equipment. When the interference disappears, the problem component has been found.
Try re-arranging cabling from the suspect source away from other cabling and ensure that the
cabling used is high quality, specified for its purpose and properly screened.
If the problem persists, please contact your installer or dealer.
The source switching changes randomly or freezes on one source.
Check that there are no static or impulse interference problems caused by nearby power equipment
switching, e.g., heating or air conditioning control. Switch the AVP700 off, wait ten seconds, then
switch it on again to clear an operating problem. Contact your installer if the problem returns or
persists.
A particular input cannot be selected in Zone 2.
Ensure that you have not blocked that particular input. See the ‘Access’ line of ‘Zone 2 Settings’ in
the Set-up Menu.
When Zone 2 is put into stand-by, the main zone is also turned off.
Check that the ‘Zone 2 Stand-by’ line of ‘Zone 2 Settings’ in the Set-up Menu is set to Local Only.
No Zone 2 audio when playing DTS film.
Many DVD players cannot output a stereo decoded version of a DTS signal – the analogue outputs
are muted when playing back DTS films. If you want to watch a DVD in both the Main zone and
Zone 2, try using the Dolby Digital sound track.
No centre image (vocal) in Zone 2 when using the multi-channel input.
Most DVD/SACD players are unable to provide a two-channel down-mix of source material at
the same time as decoding a multi-channel audio stream. Therefore, only the front left and right
channels from the multi-channel mix will be available in Zone 2.
To overcome this, play the stereo mix from the DVD-audio disc instead.
Strange aspect ratio of video in Zone 2.
Most DVD players can decode video only to one aspect ratio at a time. For example, if you are using
wide-screen in the main zone, then wide screen information will also be fed to Zone 2.
To overcome this, either set the film to 4:3 for the main zone when you want to use Zone 2 as well,
or change the Zone 2 display to a wide screen capable type.
Unable to adjust bass and treble controls.
Bass and treble is not available in ‘Direct’ mode. For Analogue Stereo and Digital Stereo modes,
check that the ‘Auto Stereo Tone Bypass’ line of ‘Speaker Eq’ in the Set-up Menu is set to
NO .
Digital signal drops out when other electrical appliances turn on (heating, fridge, etc.).
If a poor quality or incorrect cable has been used for the digital inputs, they can pick up electrical
noise. Change the cable to a 75Ω low-loss coaxial type.
Check the connections have not oxidised. Clean the connectors with contact cleaner if they appear
oxidised.
