Brooks Audio Design

An electric guitar or device played like an electric guitar that puts out MIDI signals that can be used to control synthesizers and sound modules. Line Level 1) An amplified signal level put out by an amplifier and used as the normal level that runs through the interconnecting cables in a control room. 2) A low level signal such as the signal in a guitar cord. Most parts of a PA require a line level signal. Remember, however, that speaker outputs are not line level. Plugging speaker outs into line ins will result in damage to the equipment Brooks Audio Design QS 70 High Impedance Cord (High Z) A big word for instrument cable. These cords generally have quarter inch male ends. they tend to loose signal strength at lengths longer than 25 feet. 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). Brooks Cinema xm 808 Equalizer (Parametric, Graphic) This is used ...

An abbreviation of Audio Engineering Society. Error Detection The process of discovery that sonic information bits have been lost in digital audio. Brooks Cinema Projectors Linearity The extent to which any signal handling process is accomplished without amplitude distortion. Cut 1) One selection (one song) on a pre4ecorded music format. 2) A term with the same meaning as Mute (to turn off a channel or a signal). 3) To reduce gain of a particular band of frequencies (with an equalizer). 4) To not pass a particular band of frequencies (said of a filter) Brooks GT 845 Effects Electronic boxes (usually rack mounted) added to a PA system to subtly change and enhance the signals going through it. Examples include; Reverb, Delay, Compressor, Chorus. Attack The rate the sound begins and increases in volume. Electric Instrument Any musical instrument that puts out an electrical signal rather than an acoustic sound. Board 1) Another, less formal...

1) A route leading from one side of the stage to the other, out of the audiences view. 2) An electronic filter in a sound system that routes sound of the correct frequency to the correct part of the speaker system. Different speakers handle high frequencies (tweeters) and low frequencies (woofers). Sometimes known as a crossover network. An active crossover splits the signal from the mixing desk into high, mid and low frequencies which are then sent to three separate amplifiers. 3) An electrical circuit that divides a full bandwidth signal into the desired frequency bands for the loudspeaker components. Corner Frequency Same as Cut-Off Frequency (the highest or lowest frequency in the pass band of a filter). (NOUN) Brooks SS 81 Foot Switch A switch placed on the floor and pressed by a musician to do various functions. Assistant Engineer A less elevated version of the term Second Engineer. Experienced seconds often place microphones, operate tape machines, break ...

Trade name for a series of noise reduction systems that have become standard on many tape playback machines. Many film soundtracks are produced using this process. Different varieties are found from Dolby B on most personal cassette players, to Dolby SR and Digital, the current state of the art for cinema. A/D An abbreviation of Analog to Digital Conversion (the conversion of a quantity that has continuous changes into numbers that approximate those changes), or Analog to Digital Converter. Brooks XB 33 Input/Output Module A set of controls, on one housing, for an in-line console that has two channels (one for recording and one for monitoring) and has controls for all console sections. Consumer Format (Consumer DIF) A standard adopted by IEC for sending and receiving digital audio based on The AES Professional Interface. Brooks Cinema XB 33 IC Abbreviation of Integrated Circuit (A miniature circuit of many components that is in small, sealed housing with prong...

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. Light Emitting Diode 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. Brooks Audio Design QS 70 House Sync A synchronization signal such as SMPTE time code that is used by all recorders in the control room. AES An abbreviation of Audio Engineering Society. Brooks GT 845 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. Horn 1) The part of the speaker that emits midrange and higher range frequencies. 2) A speaker or ...

A Compact Disc used to store digital data, such as large programs, that can be read by a computer. Gain Structure The way in which the gain varies in the stages or sections of an audio system. Brooks Cinema KM 22 Error Message A prompt on a computer screen telling the operator that an error has occurred. Coax Two-conductor cable consisting of one conductor surrounded by a shield. Brooks TM-22 Far Field The area from 3 feet away from the sound source up to the critical distance. Guitar Controller An electric guitar or device played like an electric guitar that puts out MIDI signals that can be used to control synthesizers and sound modules. Clip The action of deforming a waveform during overload. Acoustic Amplifier The portion of the instrument which makes the vibrating source move more air or move air more efficiently; this makes the sound of the instrument louder. Examples of acoustic amplifiers include: 1) The body of an acoustic guitar, ...

A balanced cable used for low impedance microphones and sometimes for connections between some parts of the PA. Commonly referred to as a "mic cord". Howlback 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). Brooks Cinema GT 845 Chip 1) A slang term with the same meaning as the term IC (a miniature circuit of many components that is in small, sealed housing with prongs to connect it into equipment). 2) The thread cut away from the master lacquer to make the groove, while disc recording. Cord (Speaker, Mic, Instrument) Used to connect a sound system together. Each type of cord is made for a specific purpose and should not be used in place of another type of cord, not even if they look alike. Also see "cable" Brooks Cinema NZ 60 Cut-Off Frequency (Turnover Frequency) 1) The highest or lowest frequency in the pass band of a filter. 2) The hig...
