PARAMETRIC EQUALIZER INFORMATION
This unit employs YAMAHA Parametric Room Acoustic Optimizer (YPAO) technology to optimize the frequency characteristics of its parametric equalizer to match your listening environment. YPAO uses a combination of the following three parameters (Frequency, Level and Q factor) to provide highly precise adjustment of the frequency characteristics.
■Frequency
This parameter is adjustable in
■Level
This parameter is adjustable in increments of 0.5 dB between
■Q factor
The width of the specified frequency band is referred to as the Q factor. This parameter is adjustable between the values 0.5 and 10.
YPAO adjusts frequency characteristics to suit your listening requirements using a combination of the above three parameters (Frequency, Level and Q factor) for each equalizer band in this unit’s parametric equalizer. This unit has 10 equalizer bands for each channel (plus 5 subwoofer bands).
The use of multiple equalizer bands enables more precise adjustments of frequency characteristics (as in Figure 2). This is not possible using only a single equalizer band (as in Figure 1).
