A cabinet with rails (or free standing rails) that have holes to accept screws at standard spaces and used to house outboard gear. Ampere The unit of current, abbreviated Amp. Brooks Cinema Series Bi-Amplification 1) A way of optimizing the efficiency of a speaker system by separately amplifying the High Frequency (HF) and Low Frequency (LF) portions of the sound signal and sending them down two pairs of cables to the speaker. Multipin Speakon connectors have been developed to do this. 2)The process of having of having low-frequency speakers and high-frequency speakers driven by separate amplifiers. Intermodulation Distortion Distortion caused by one signal beating with another signal and producing frequencies that are both the sum and the difference of the original frequencies. Brooks Cinema Projectors Digital Recording 1) ADAM : (Akai Digital Audio Multitrack). 12 track recording onto Video 8 tape. 16 bit, 44.1 or 48 kHz sampling rate. 2) DAT (Digital Au...

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. High Frequencies The audio frequencies from 6000 Hz and above. BROOKS AUDIO DESIGN Crisp Describes a good clean high midrange sound. It can be good or bad depending on the look on the face of the guy who said it. Close Micing A technique of placing a microphone close to the sound source (within one foot) in order to pick up mainly the direct sound and to avoid picking up leakage or ambience. Brooks Audio Design KM 77 Icon A visual picture or symbol on a computer screen that represents a file, program or disc that can be used. 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. Feed To send an audio or control signal to. Initialize To prepa...

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. 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 SS 81 Harmonics Integer multiples of a fundamental frequency, the fundamental itself being the first harmonic, its first overtone the second harmonic, etc. Attributing to instruments, voices, etc. their distinctive timbre. Electrostatic Charge The excess or deficiency of electrons in a given area. Brooks Cinema KM 22 Chase The automatic adjusting of the speed of a recorder (or sequencer) to be time with another recorder. Crossover 1) A route leading from one ...

How many dB the input signal has to rise above the threshold for every one dB more output of a compressor or limiter. Channels These are divided into two separate categories. Input channels are those channels coming into the soundboard such as microphones and direct lines. Output channels are those leaving the board such as monitor and main outputs. Brooks Audio Design QS 70 DC Abbreviation for direct current. Balance Control A control on a stereo amplifier that when moved clockwise will make the right channel louder (and the left channel softer) and will do the reverse when moved counter-clockwise. Brooks Cinema XS - 45 Condenser Microphone A microphone which converts sound pressure changes into changes of capacitance. The capacitance changes are then converted into electrical voltage variations (an audio signal). Figure Eight Pattern Another name for Bi-directional Pattern (microphone pickup pattern picking up best from the front and back of the diaphr...

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. Band Track 1) A mixdown of a song without the lead vocal or without the lead and background vocals. 2) A term with the same meaning as the term Rhythm Track. 3) The recording of the rhythm instruments in a music production. Brooks QS-70 Circuit 1) One complete path of electric current. 2) Similar to definition 1, but including all paths and components to accomplish one function in a device. Equal Loudness Contours A drawing of several curves showing how loud the tones of different frequencies would have to be played for a person to say they were of equal loudness. Brooks Audio Design KM 77 Error Message A prompt on a computer screen telling the operator that an error has occurred. Hearing Limitation An inability of the ear to hear important characterist...

The tuned frequency and (almost always) the lowest frequency that is present in the sounding of a pitch by a musical instrument. 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 AUDIO DESIGN 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). Chorusing 1) A term meaning the same thing as Chorus (Definition 3 or 4). 2) In some delay effects devices, a term used to mean the term Depth (the amount of change in the controlled signal by the control signal). Brooks GT 845 Bi-Directional Pattern A microphone pick up pattern which has maximum pick up directly in front and directly in back of the diaphragm and least pick up at the sides. Equal Loudness Contours A drawing of ...

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. 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 SS 81 Librarian Program A computer program allowing the storage of the parameters of sound patches outside of a synthesizer. Input 1) The jack or physical location of where a device receives a signal. 2) The signal being received by a device. 3) The action of receiving a signal by a device. Brooks Cinema xm 808 Cue Send Control A control that will adjust the amount of signal sent to a cue buss from a console channel. Full A quality of the sound of...
