Adjusting surround effect

This unit features YAMAHA's unique "Virtual 3D" technology, which provides a virtual surround sound effect with only two
speakers. In the sound field of the "Virtual 3D" mode, two virtual rear speakers are provided as well as two front speakers (L,
R) to achieve the surround-sound effect.
To optimize the surround-sound effect, adjust the volume of each speaker in the sound field by listening to a series of test
tones.
