Troubleshooting—Continued
There’s no sound
• Only components connected to analog inputs can be
played in Zone 2/3.
Can’t access the server or Internet radio
• Check the network connection between the AV con-
troller and your router or switch.
• Make sure that your modem and router are properly
connected, and make sure they are both turned on.
• Make sure the server is up and running and compatible
with the AV controller (page 120).
• Check the “Network Settings”(page 121).
Playback stops while listening to music files on
the server
• Make sure your server is compatible with the AV con-
troller (page 120).
• If you download or copy large files on your computer,
playback may be interrupted. Try closing any unused
programs, use a more powerful computer, or use a
dedicated server.
• If the server is serving large music files to several net-
worked devices simultaneously, the network may
become overloaded and playback may be interrupted.
Reduce the number of playback devices on the net-
work, upgrade your network, or use a switch instead
of a hub.
Can’t connect to the AV controller from a Web
browser
• If you’re using DHCP, your router may not always
allocate the same IP address to the AV controller, so if
you find that you can’t connect to a server or Internet
radio station, recheck the AV controller’s IP address
on Network screen.
• Check the “Network settings” (page 121).
Can’t access the music files on a USB device
• Make sure the USB device is plugged in properly.
• The AV controller supports USB devices that support
the USB mass storage device class. However, play-
back may not be possible with some USB devices
even if they conform to the USB mass storage device
class.
• USB memory devices with security functions cannot
be played.
The sound changes when I connect my
headphones
• When a pair of headphones is connected, the listening
mode is set to Stereo, unless it’s already set to Stereo,
Mono, Direct, Pure Audio or DTS Surround Sensa-
tion.
The speaker distance cannot be set as required
• In some cases, corrected values suitable for home the-
ater use may be set automatically.
The display doesn’t work
• The display is turned off when the Pure Audio listen-
ing mode is selected.
How do I change the language of a multiplex
source
• Use the “Multiplex” setting on the “Audio Adjust”
menu to select “Main” or “Sub” (page 94).
The u functions don’t work
• To use u, you must make an u connection and an
analog audio connection (RCA) between the compo-
nent and AV controller, even if they are connected dig-
itally (page 42).
• While Zone 2 or Zone 3 is selected, the u functions
don’t work.
The functions Auto Power On/Standby and
Direct Change don’t work for components
connected via u
• These functions don’t work when Zone 2/3 is turned
on.
When performing “Audyssey MultEQ
®
XT
Room Correction and Speaker Setup”, the
measurement fails showing the message
“Ambient noise is too high.”.
• This can be caused by any malfunction in your speaker
unit. Check if the unit produces normal sounds.
