Yamaha RX-V661 Parametric equalizer information, 107 En, ■Gain, ■Q factor, ■Frequency

Parametric equalizer information

This unit employs Yamaha Parametric Room Acoustic Optimizer (YPAO) technology, together with the Parametric EQ settings (see page 75), 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.

■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.

■Gain

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, 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).
