When the function is set to LINE2 (Europe model) or LINE
•
(Except Europe model), the Surround setting is fixed to
5-channel STEREO, which is only for Service Test mode.
(In Normal mode, it is fixed to 2-channel STEREO.) In such
a case, do not check the sound through the headphones,
because headphone operation with 5-channel STEREO is
not guaranteed. If you wish to check the sound through the
headphones, use a function other than LINE2 (Europe
model) or LINE (Except Europe model).
