I have a yamaha noob question, whats the Parametric Equalizer for in a non technical explanation? What does that thing do?
More simplified:
An equalizer adjusts frequencies in a given signal. The simplest one is a tone control adjustment.
More advanced is the one with separate adjustments for bass and treble. Even more advanced is a graphic equalizer, which typically allows adjustments for 5 to 10 frequencies.
The most advanced is the parametric equalizer, which provides the most accuracy by allowing adjustments to 3 parameters: amplitude, center frequency, and bandwidth ("Q").
What does parametric equalization do?
Your listening room changes the original sound as recorded on the video disc. To compensate for a listening rooom's deficient design, parametric equalization adjusts the sound so that what you hear is as close to the original quality as possible.
