This pedal is a parametric equalizer. Equalization, or simply EQ, in sound recording and reproduction is the process of adjusting the volume of different frequency bands within an audio signal. The circuit or equipment used to achieve this is called an equalizer. [1] [2] Most hi-fi equipment uses relatively simple filters to make bass and ...
The original stand-alone unit was called the ITI ME-230 (Mastering Equalizer 230) and was the first commercially available parametric EQ. [1] [4] Massenburg and Macneal type-set and printed a paper entitled “Parametric Equalization” in 1972 and Massenburg submitted it to the Audio Engineering Society in Los Angeles.
George Y. Massenburg (born Baltimore, Maryland c. 1947) is a Grammy award-winning recording engineer and inventor.Working principally in Baltimore, Los Angeles, Nashville, and Macon, Georgia, Massenburg is widely known for submitting a paper to the Audio Engineering Society in 1972 regarding the parametric equalizer.

Digital room correction may involve minimum phase algorithms, to maintain wavefront coherence over the intended frequency range.. The use of analog filters, such as equalizers, to normalize the frequency response of a playback system has a long history; however, analog filters are very limited in their ability to correct the distortion found in many rooms.
A television equalizer consequently typically requires more filter sections than an audio equalizer. To keep this manageable, television equalizer sections were often combined into a single network using ladder topology to form a Cauer equalizer. The second issue is that phase equalization is essential for an analog television signal.
The channel input strips are usually a bank of identical monaural or stereo input channels arranged in columns. Typically, each channel's column contains a number of rotary potentiometer knobs, buttons, and faders for controlling the gain of the input preamplifier, adjusting the equalization of the signal on each channel, controlling routing of the input signal to other functional sections ...
