This unit creates a sound field by reflecting sound beams on the walls of your listening room and broadening the
cohesion between speaker 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 feature and the YAMAHA Parametric Room Acoustic Optimizer (YPAO)
technology with the aid of the supplied optimizer microphone, allowing you to avoid troublesome listening-based
speaker setup and achieving highly accurate sound adjustments that best match your listening environment.
The beam optimization is the automated feature of BASIC SETUP, which creates the best possible surround sound field
without manually setting the parameters for your listening room.
The YAMAHA Parametric Room Acoustic Optimizer (YPAO) technology performs the following checks and
automatically makes appropriate sound adjustments.
DISTANCE:
Checks the phase and the distance of each beam from this unit and adjusts the delay of each channel so that each sound
beam reaches the listening position at the same time.
EQUALIZING:
Adjusts frequency and levels of each channel’s parametric equalizer to reduce coloration across the channels and create a
cohesive sound field. YPAO equalizing calibration incorporates three parameters (frequency, level and Q factor) for each
of the seven bands in its parametric equalizer to provide highly precise automatic adjustment of frequency characteristics.
LEVEL:
Checks and adjusts the sound output level of each channel.
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.
