The container of air that is pressurized by the backward motion of a speaker driver. Loosely any type of relative frequency adjustment. A component designed to alter the frequency balance of an audio signal. Equalizers may be standard, graphic, parametric, or a combination of these types. The transmission of current or voltage from the output of a socket or device back to the input, where it interacts with the input signal to modify operation of the device.
Feedback is positive when it's in phase with the input, and negative when it's out of phase.
The reproduction of sound without altering the intensity of any part of the frequency range. A speaker designed to reproduce the full range of audio frequencies. Most full-range speakers can't reproduce very low or very high frequencies loud enough, but reproduce mostly midrange frequencies. The generation of harmonics by the circuit or device by which the signal is processed. Abbreviation of High Definition Television.
