PARAMETRIC EQUALIZER INFORMATION 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 one-third octave increments between 63 Hz and 16 kHz. ■ 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. ■ Level This parameter is adjustable in increments of 0.5 dB between -20 and +6 dB. 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).

PARAMETRIC EQUALIZER INFORMATION
120
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 one-third octave
increments between 63 Hz and 16 kHz.
■
Level
This parameter is adjustable in increments of 0.5 dB
between –20 and +6 dB.
■
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).
