When the function is set to LINE, 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 LINE.
