Brooks Audio Design

The opposition to current flow by the first circuits of a device. Error Correct Exact replacement of lost information bits in digital audio. Brooks GT 44 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. Imaging To make a representation or imitation of the original sonic event. Brooks SS 81 Cascade To set and interconnect two mixers so that the stereo mixing buss(es) of the first mixer feeds the stereo buss(es) of a second mixer. 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. ...

An abbreviation of Beat Per Minute (the number of steady even pulses in music occurring in one minute and therefore defining the tempo). Amplitude The strength of a vibrating wave; in sound, the loudness of the sound. Brooks Cinema ZL 44 Auxiliary Equipment Effects devices separate from but working with the recording console. Capacitor 1) A device consisting of two or more conducting plates separated from one another by an insulating material and used for storing an electrical charge. Sometimes called a condenser. 2) An electronic device that is composed of two plates separated by an insulator. Brooks QS 70 Hearing Limitation An inability of the ear to hear important characteristics of sound under certain conditions. Characteristics that can be affected include pitch, level, clarity, presence and direction. Key The control of a dynamics processing device by an external audio signal. Floppy Disk (Floppy Disc) A round flat object (usually housed in...

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. Golden Section A ratio of height to width to length of a room to achieve "good acoustics" and first recommended by the ancient Greeks. The ratio is approximately the width 1.6 times the height and the length 2.6 times the height Brooks XB 22 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" Boost To increase gain, especially to increase gain at specific frequencies with an equalizer. Brooks QS 70 Automation In consoles, a feature that lets the engineer program control changes (such as fader level) so that upon playback of the multitrack recording these changes happen automatically. Echo Send The outpu...

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. High Impedance Impedance of 5000 or more ohms. Brooks Cinema Series Feedback 1) The delayed signal sent back to the input of a delay line, used in repeat-echo effects. 2) The pickup of the signal out of a channel by its input or the howling sound that this produces. 3) In an amplifier, the phase reversed output signal sent back to its input, reducing gain but also distortion and noise. 4) This occurs when the sound coming out of the speakers goes back into the microphones, then back out the speakers, then back into the mics…and so on. This can build very quickly to a point where everyone in the room is holding their ears and screaming at you. It can also cause damage to the PA. Level Sets output volume of individual PA input channels. Usually positioned as sliders at the bottom of the soundboard. Brooks M ...

To make a representation or imitation of the original sonic event. Direct box Used in line to convert a high impedance signal into a low impedance signal. Brooks GS 15 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. Earth The British version of the term Ground (In electronics, a place that has zero volts). Brooks XT 20 Console A set of controls and their housing, which control all signals necessary for recording and mixing. Linearity The extent to which any signal handling process is accomplished without amplitude distortion. Headstock The area of the guitar at the end of the neck where the strings are tuned. Attack The rate the sound begins and increases in volume.

The frequency of the audio signal that is boosted or attenuated most by an equalizer with a peak equalization curve. 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. Brooks Cinema TX 509 Equalization 1) The process of adjusting the tonal quality of a sound. A graphic equalizer provides adjustment for a wide range of frequency bands, and is normally inserted in the signal path after the mixing desk, before the amplifier. See Feedback. 2) Any time the amplitude of audio signals at specific set of frequencies are increased or decreased more than the signals at other audio frequencies. Analog Recording A recording of the continuous changes of an audio waveform. Brooks Cinema RM 909 Condenser Microphone A microphone which converts sound pressure changes into changes of capacitance. The capacitance changes are then converted into...

Usually undesirable result of overloading sound equipment. Reducing the levels can remedy the situation. Integrated Circuit (IC) A miniature circuit of many components in a small, sealed housing with prongs to connect it into equipment. Brooks GS 15 Insulator A substance such as glass, air, plastic, etc., that will (for all practical purposes) not conduct electricity. Engineer 1) A technician in charge of a recording session; Also called Recording Engineer. 2) A person with an engineering degree. 3) A person with sufficient experience in the field to be equivalent to the education one would receive earning an engineering degree. Brooks Speakers Byte A grouping of eight information bits. High Impedance Impedance of 5000 or more ohms. In-Line Console A console with modules that have controls for all console sections in one long strip. Compression Driver The unit that feeds a sound pressure wave into the throat of a horn (in a horn loudspeak...
