Adjusting DSP sound field parameters
You can adjust various parameters of the DSP sound field
programs.
The default parameters of the sound field programs provide
great sound, but it is also possible to fine-tune the
parameters to suit the acoustics of the room, individual
preferences, and program source. Parameter adjustment
is required for each selected sound field program.
