Listening to External Components
Adjusting the Audio Input Level
If the sound from the component connected to the LINE IN 
jack is too loud or is too quiet when changing from another 
source to “LINE,” you can change the audio input level 
through the LINE IN jack (without changing the volume 
level).
While LINE is selected as the source...
Switching to LINE Automatically
—QP Link 
Quick Portable Link (QP Link) automatically switches the 
source to LINE as the auxiliary equipment connected to the 
LINE IN jack starts playback.
• Make sure to set the volume of your portable audio device 
loud enough so that the System can detect the sound signal.
• QP Link does not work when the System is operating on 
batteries.
To activate QP Link
When QP Link is activated, connecting a portable device to 
the LINE IN jack and starting playback performs the 
following:
• While listening to another source...
Changes the source to LINE automatically. (If you change 
from LINE to another source, QP Link will be canceled.)
• While the System is on standby...
Turns on the System and changes the source to LINE 
automatically (not applicable when the display is turned 
off).
To deactivate QP Link
Changing the QP Link Sensitivity 
You can change the LINE IN jack sensitivity if QP Link 
malfunctions by detecting non-playback signals such as 
switching noises from the auxiliary equipment.
While LINE is selected as the source...
LEVEL 1 Select this when the sound is too loud with 
“LEVEL 2” selected. This setting is 
recommended when connecting an audio 
device other than a portable audio device 
to the LINE IN jack.
LEVEL 2 Select this when the sound is too loud with 
“LEVEL 3” selected.
LEVEL 3 Select this when listening to a portable
