ION

This unit employs YAMAHA Parametric Room Acoustic
Optimizer (YPAO) technology, together with the
Parametric EQ settings (see page 89), to optimize the
frequency characteristics of its parametric equalizer to
match your listening environment. YPAO uses a
combination of the following three parameters
(Frequency, Gain and Q factor) to provide highly precise
adjustment of the frequency characteristics.

Frequency

This parameter is adjustable in one-third octave
increments between 32 Hz and 16 kHz.

Gain

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, Gain and Q factor) for each
equalizer band in this unit’s parametric equalizer. This unit
has 7 equalizer bands for each channel.
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).
