Yamaha RX-V661 User Manual

You can enjoy good quality sound with the initial factory 
settings. Although you do not have to change the initial 
factory settings, you can change some of the parameters to 
better suit the input source or your listening room.

You cannot change the sound field parameter values when 
“MEMORY GUARD” in “OPTION MENU” is set to “ON” (see 
page 82). If you want to change the sound field parameter values, 
set “MEMORY GUARD” to “OFF”.
