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 Foldback A European term for the signal sent to the stage monitors in a live performance. Brooks Cinema ZL 44 Electret Condenser A condenser microphone that has a permanently polarized (charged) variable capacitor as its sound pressure level sensor. Formant An element in the sound of a voice or instrument that does not change frequency as different pitches are sounded. Brooks QS-70 Librarian Program A computer program allowing the storage of the parameters of sound patches outside of a synthesizer. Beat 1) The steady even pulse in music. 2) The action of two sounds or audio signals mixing together and causing regular rises &.falls in volume. Guitar Processor A unit that will add effects to a direct guitar signal, including a simulated instrument amplifier sound and (often) delay and reverb effects. C...

A speaker design where the speaker points back into the cabinet and bounces around finally coming out large ports in the front. It is intended to maximize low frequencies in a relatively small cabinet. Central Processing Unit 1) The main "brain" chip of a computer that performs the calculations and execution of instructions. 2) The main housing of a computer that contains the "brain" chip as opposed to other pieces of the computer system such as keyboards, monitors, etc. Brooks TM-22 LED A light that allows current to flow in one direction only and emits light whenever a voltage of a certain level or beyond is applied to it. Integrated Circuit (IC) A miniature circuit of many components in a small, sealed housing with prongs to connect it into equipment. Brooks Speakers Linear The condition of obtaining a change at the output of the device which is proportional to the change occurring at the input. Active Crossover Uses active devic...

The property of an electric circuit by which a varying current in it produces a varying magnetic field that introduces voltages in the same circuit or in a nearby circuit. It is measured in henrys. Amplifier Sound equipment that converts the low voltage, low current signal from a tape deck, mixer etc. into a higher current signal suitable for driving speakers. See Power Amplifier, Crossover. Brooks XB 33 Electromagnetic Theory A statement of the principles behind electromagnetic induction: When a conductor cuts magnetic lines of force, current is induced in that conductor. 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 Brooks Cinema XS - 45 I/O Short for "Input/Output' and referring to: 1) An in-line console module that contains controls for the input section, output section and monitor section. 2) A module in electronic gear containing input and ou...

The acoustic power delivered for a given electrical input. Often expressed as decibels/watt/meter (dB/w/m). ESL �" Abbreviation for electrostatic loudspeaker. Ground Adapter Plug Adapts a three pronged electrical plug to a two pronged wall outlet. This bypasses the ground and may create a hum in the system. A lack of a good ground can cause mild electrical shock when touching a microphone. Brooks Cinema NZ 60 Bridge The bridge assembly, or just "bridge" is an area on the face of the guitar where the string meet or are connected to the face. 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 TM-22 Format 1) The number of tracks, their width, spacing and order for tape recording. 2) To prepare a digital storage medium so that it will accept and store digital information bits. Cue 1...

1) On a tape machine, the housing for and the channel circuitry which processes the signal to be fed to the heads, provide bias, and playback. 2) The branch of science dealing with the behaviour of electrons/charges in vacuums, gases, semiconductors and special conductors. Gate A dynamic processing device that turns a channel off or down when the signal drops below a certain level. Brooks QS 70 Effects Track 1) In film production audio, a recording of the mixdown of all the sound effects for the film ready to be mixed with the dialogue and music. 2) In music recording, one track with a recording of effects to be added to another track of a multitrack recording. Auxiliary Output or Send An additional output from a sound desk that can be used for foldback or monitoring without tying up the main outputs. Each input channel will have a path to the Aux buss. Also used for feeding a signal to an effects processor. See Auxiliary Return. Brooks Cinema ZL 44 Kick (Ki...

Refers to the speakers that face toward the audience. Also called the "main" speakers. Chorus Common type of effect that makes sounds fuller and thicker. Brooks Audio Design QS 70 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. I/O Short for "Input/Output' and referring to: 1) An in-line console module that contains controls for the input section, output section and monitor section. 2) A module in electronic gear containing input and output amplifiers for the device. 3) A digital port (connector) able to both receive digital data and output digital data. Brooks Cinema XB 33 Fade 1) A gradual reduction of the level of the audio signal. 2) A gradual change of level from one pre-set level to another. Ground Lifter An adapter that takes a three prong power cord and plugs into a...

1) Relative measurement for the volume (loudness) of sound. Also used to measure the difference between two voltages, or two currents. See Zero dB. 2) A numerical expression of the relative loudness of a sound. The difference in decibels between two sounds is ten times the common logarithm of the ratio of their power levels. Flat 1) Lower in musical pitch. 2) A slang term used to describe the sensitivity to frequency of a microphone, amplifier, etc., as being even at all frequencies, usually within 2 dB. 3) Refers to the frequencies on the EQ when they are arranged in centred neutral positions. Brooks Cinema Series Critical Distance The point a distance away from the sound source where the direct sound and the reverberant sound are equal in volume. Hypercardioid Pattern A microphone pick up sensitivity pattern where the least sensitive pick up point is more than 90 degrees but less than 150 degrees off axis (usually 120 degrees).
