Yamaha YSP-300 Owner's Manual page 39

This unit creates a sound field by reflecting sound beams on the walls of your listening room and by broadening the
cohesion of all the channels. Just as you would arrange the speaker position of other audio systems, you need to set the
beam angle to enjoy the best possible sound from this unit.
This unit employs the beam optimization and sound optimization features with the aid of the supplied IntelliBeam
microphone, allowing you to avoid troublesome listening-based setup and achieving highly accurate sound adjustments
that best match your listening environment. We call these two features
"lntelliBeam"
generically.
Beam optimization:
This feature optimizes the beam angle so that the parameter best matches your listening environment.
Sound optimization:
This feature optimizes the beam delay, volume, and quality so that the parameters best match your listening environment.
This unit performs a series of checks to optimize the beam angle, delay, volume, and quality. You can choose to optimize
all or part of the parameters.
