Technology / Home Audio / Parametric Equalizer: A multi-band equalizer enabeling control of at least three essential 'parameters' of the internal bandpass filter sections. These parameters being: amplitude, center frequency and bandwidth. This allows the user to not only control the amplitude of each band, but also to shift the center frequency and to widen or narrow the width or coverage of the affected section of the aural spectrum. Regulation is done by either rotary and slide controls. Other types of parametric equalizers exist which allow control of center frequency, but not bandwidth. For rotary control units, the most common term is quasi-parametric. For units with slide controls the popular term is paragraphic. The frequency control may be continuously variable or switch selectable in steps. Cut-only parametric equalizers (with adjustable bandwidth or not) are called notch equalizers, or band-reject equalizers.
Technology / Home Audio / Quasi-Parametric: A type of equalizer. A quasi-parametric (also known as 'semi-parametric') EQ will allow control over the frequency and gain of each band of equalization, but not the number of frequencies controlled ( MORE
Technology / Home Audio / Equalizer (EQ): A class of electronic filter circuits designed to augment or adjust electronic or acoustic systems. Equalizers can be fixed or adjustable, active or passive. Most consumer audio equallizers divide the MORE
