Yamaha RX-V3900 Parametric equalizer information, 144 En, ■Gain, ■Q factor, ■Frequency

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, 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).
