Brooks RM 909 Figure Eight Pattern Another name for Bi-directional Pattern (microphone pickup pattern picking up best from the front and back of the diaphragm and not picking up from the side of the diaphragm). Capacitance That property of a capacitor which determines how much charge can be stored in it for a given potential difference between its terminals, measured in farads, by the ratio of the charge stored to the potential difference. Brooks Hi Fi reviews Input Monitor A switch position and operational mode of the electronics of a tape machine where the signal at output of the electronics will be the same as the signal coming into the electronics. I

Short for the term High Frequencies (the audio frequencies from 6000 Hz and above). Byte A grouping of eight information bits. Brooks Hi Fi reviews Attenuation A making smaller: reduction of electrical or acoustic signal strength. Attack The rate the sound begins and increases in volume. Brooks RM 909 reviews Keying Input (Key Input) An input on a dynamics processing device to control the device by an external audio signal. Humbucker Pickups that are coupled together to get a certain sound. Field 1) In video, one half of a frame. 2) In computer-controlled devices a window display with functions and choices that the operator can make Level The amount of signal strength; the amplitude, especially the average amplitude.

A product created by the marriage of two different technologies. Meant here as the combination of a dynamic woofer with an electrostatic transducer. Delay Outboard sound equipment that can momentarily stores a signal being sent to part of a P.A. system so that delayed reinforced sound reaches the audience at the same time as live sound from the stage. Brooks RM 909 reviews High Hat A double cymbal on a stand which can be played with a foot pedal or by the top cymbal being hit with a stick. Amp 1) An abbreviation of the term Amplifier (A device which increases the level of an electrical signal. 2) An abbreviation of Ampere (the unit of current). 3) An abbreviation of amplitude (the height of a waveform above or below the zero line).
