This listening mode can be selected for all input signals. Processing that affects
sound quality is shut down, and sound closer to the original is reproduced. The
sound is reproduced with the sound field based on the number of channels
in the input signal. For example, a 2 ch signal is output only from the front
speakers.
Note that the sound adjustment is not available when this mode is selected.

This listening mode expands 2 ch or 5.1 ch input signals to 5.1 ch, 7.1 ch or
5.1.2 ch. This mode expands actual channels to more channels for playback
according to the configuration of the connected speakers. Also, even if there is
no speaker for expansion, for example when only front speakers are connected,
audio of surround channel or height channel is virtually created for expansion
playback.
