PARAMETRIC EQUALIZER INFORMATION
112
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).
