Brooks Audio Design

The control of a dynamics processing device by an external audio signal. Error Correct Exact replacement of lost information bits in digital audio. Brooks Gt 44 Diaphragm A thin flexible membrane or cone that vibrates in response to electrical signals to produce sound waves. Distortion is usually referred to in terms of total harmonic distortion (THD) which is the percentage of unwanted harmonics of the drive signal present with the wanted signal. Generally used to mean any unwanted change introduced by the device under question. Full A quality of the sound of having all frequencies present, especially the low frequencies. BROOKS HI fi Blending 1) A condition where two signals mix together to form one sound or to give the sound of one sound source or one performance. 2) Mixing the left and right signal together slightly which makes the instruments sound closer to the center of the performance stage. 3) A method of panning during mixing where instruments are ...

1) The frequency that is the outer limit of one of the bands of a crossover. 2) In the Lexicon 480L delay/reverberation effects unit, the frequency at which the bass frequency reverb time is in effect rather than the mid frequency reverb time. Head 1) In tape recording, the transducer (energy converter) that changes the audio energy from electrical energy to magnetic energy and back; also the devices that apply magnetism to the recording tape for other purposes such as in the erase head. 2) The part of a device that immediately includes the transducer to change sound or audio signals from one energy form to another. Brooks Gt 44 Front Loaded A speaker cabinet where the speaker faces out toward the front. 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 KM 22 Cable, XLR A balanced cable used for low impedance microphones and sometimes for connections bet...

A slide control used to send out a control voltage to several VCA faders in individual channels, thus controlling the gain of several channels. Blending 1) A condition where two signals mix together to form one sound or to give the sound of one sound source or one performance. 2) Mixing the left and right signal together slightly which makes the instruments sound closer to the center of the performance stage. 3) A method of panning during mixing where instruments are not panned extremely left or right. Brooks KM 22 Group Faders The VCA faders of individual channels that are all controlled by a Group Master Fader (a slide control used to send out a control voltage to several VCA faders in individual channels). Insulator A substance such as glass, air, plastic, etc., that will (for all practical purposes) not conduct electricity. Brooks Cinema Projectors Integrated Circuit (IC) A miniature circuit of many components in a small, sealed housing with prongs to co...

British term for the term Feedback (the pickup of the signal out of a channel by the input of the channel or the howling sound that this produces). ID An index signal (digital data that gives the machine information of where selections start, their selection number, etc.) on a DAT or CD. Brooks Cinema DESIGN ZL 44 Folded Horn 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. Frequency Response How sensitive an electronic device (mic, amplifier, speaker, etc.) is to various frequencies; often communicated with a graph. Brooks GT 845 Assistant Engineer A less elevated version of the term Second Engineer. Experienced seconds often place microphones, operate tape machines, break down equipment at the session end and keep the paperwork for the session. Far Field The area from 3 feet away from the sound source ...

Feeding the output of an electric instrument (like an electric guitar) to the recording console or tape recorder without using a microphone. Assistant Engineer A less elevated version of the term Second Engineer. Experienced seconds often place microphones, operate tape machines, break down equipment at the session end and keep the paperwork for the session. Brooks GT 845 kHz An Abbreviation of kilo-Hertz. Cycles Per Second A unit used in the measure of frequency, equivalent to Hertz. Cycles Per Second is an outdated term replaced by Hertz in 1948. BROOKS HI fi Line 1) Short for line level. 2) A cable. CD-ROM An abbreviation of the term Compact Disc, Read Only Memory (A Compact Disc used to store digital data, such as large programs, that can be read by a computer). Absorption Short for the term Acoustical Absorption (quality of a surface or substance to take in, not reflect, a sound wave). Gain Control A device that changes the gain of an ...

The action of deforming a waveform during overload. Bi A prefix meaning two. Broom RM 909 Line In (Input, return) Where a signal enters the board or component. House Sync A synchronization signal such as SMPTE time code that is used by all recorders in the control room. Brooks KM 22 Cardioid Pattern A microphone pick up pattern, which has maximum pick up from the front, less pick up from the sides, and least pick up from the back of the diaphragm. Icon A visual picture or symbol on a computer screen that represents a file, program or disc that can be used. DC Abbreviation for direct current. Electric Current A more formal term meaning the same as the term Current (the amount of electron charge passing a point in a conductor per unit of time).

1) A room designed with very hard, non-parallel surfaces and equipped with a speaker and microphone. 2) Any artificial or electronic device that simulates the reverberation created in a room. Linearity The extent to which any signal handling process is accomplished without amplitude distortion. Brooks XM 204 Gain 1) Knob usually found at the top of each input channel on the soundboard. Used to set input levels of the separate channels to relatively equal positions. 2) The amount of increase in audio signal strength, often expressed in dB. Line Out (Line Output) Any output that sends out a line level signal, such as the output of a console that feeds a recorder. BROOKS HI fi Arc The visible sparks generated by an electrical discharge. Efficiency The acoustic power delivered for a given electrical input. Often expressed as decibels/watt/meter (dB/w/m). ESL �" Abbreviation for electrostatic loudspeaker. Expander A device that causes expansion...
