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. Compression Driver The unit that feeds a sound pressure wave into the throat of a horn (in a horn loudspeaker). Brooks Hi Fi reviews Electromagnetic Induction or Pick Up The generation of electrical signal in a conductor moving in a magnetic field or being close to a changing magnetic field.

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. Humbucker Pickups that are coupled together to get a certain sound. Brooks HI FI projectors Electrons Negatively charged particles, which revolve around the centre of atoms. The movement of such electrons down a conductor causes electrical current. Gain Structure The way in which the gain varies in the stages or sections of an audio system. Brooks RM 909 reviews Crossover, Passive Used inside of full range speaker cabinets to separate highs, mids, and lows and send them to their respective speakers within the each cabinet. These are not as efficient as active crossovers because they require all frequencies to draw from the same source of amplification. Bank 1) A collection of sound patches (data as to the sequence and operating parameters of the synthesizer generators and modifiers) in memory. 2) A group of ...

A prompt on a computer screen telling the operator that an error has occurred. Generating Element The portion of the microphone that actually converts the movement of the diaphragm into electrical current or voltage changes. Brooks RM 909 reviews kHz An Abbreviation of kilo-Hertz. Binary A numbering system based on two. In binary there are two symbols used ("l" and "0"). Brooks HI FI projectors Delay (Digital, Analogue) 1) Effect used to create echo…echo…echo…echo…echo… 2) In more advanced systems used in very large venues, delay can be used to time the arrival of the signal to the speakers in the back of the room so that people in the back hear the sound coming from those speakers at the same time that the sound coming from the speakers in the front of the room arrives. Centre Frequency The frequency of the audio signal that is boosted or attenuated most by an equalizer with a peak equalization curve. Crisp Describes a good c...

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 Audio Tape) Cassette-like system which has much higher quality than standard audio cassettes. Widely used in gathering sound effects, for news gathering, and for playback of music. 3) DCC (Digital Compact Cassette) Rival to DAT which also plays standard audio cassettes. 4) MiniDisc : Uses computer disk technology, rather than tape. A laser heats an area of magnetic disk which is then written to by a magnetic head. When cooled, the magnetic information is read from the disk by laser. Tracks can be named, and are instant start. Very theatre-friendly system. 5) Direct to Disk : Uses the hard disk present in most PCs as the recording medium. 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). B...

A setting of a digital delay/reverb effects unit that approximates concert halls. Hall programs are characterized by pre-delay of up to 25 ms. Bottom The bass frequencies (as in "needs more bottom end"). Brooks HI FI projectors Attack The rate the sound begins and increases in volume. Fret Buzz A buzzing sound made when a note is not properly fretted. Common with cheap guitars or beginning guitar players. Brooks Hi Fi reviews 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. Balls 1) The depth and thickness of a sound, usually on the bottom end of the EQ (as in "needs more balls"). 2) The strength of the voice on th...

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. Clock Signal The signal put out by a circuit that generates steady even pulses or steady codes used for synchronization. Brooks HI FI 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 Audio Tape) Cassette-like system which has much higher quality than standard audio cassettes. Widely used in gathering sound effects, for news gathering, and for playback of music. 3) DCC (Digital Compact Cassette) Rival to DAT which also plays standard audio cassettes. 4) MiniDisc : Uses computer disk technology, rather than tape. A laser heats an area of magnetic disk which is then written to by a magnetic head. When cooled, the magnetic information is read from the disk by laser. Tracks can be named, and are instant start....

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. Generation A term used to describe the number of times that the recorded audio signal has been copied. Brooks RM 909 reviews Electrostatic Charge The excess or deficiency of electrons in a given area. Crossover (Crossover Network) A set of filters that "split" the audio signal into two or more bands (two or more signals, each of which have only some of the frequencies present). Brooks HI FI projectors Attack The rate the sound begins and increases in volume. 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). Hi-Z An abbreviation of the term High Impedance (Impedance of 5000 or more ohms). Isolation ...

The height of a waveform above or below the zero line. Boom 1) A hand-held, telescoping pole used to hold the microphone in recording dialogue in film production. 2) A telescoping support arm that is attached to a microphone stand and which holds the microphone. 3) Loosely, a boomstand. Brooks RM 909 Capacitance That property of a capacitor which determines how much charge can be stored in it for a given potential difference between its terminals, measured in farads, by the ratio of the charge stored to the potential difference. Icon A visual picture or symbol on a computer screen that represents a file, program or disc that can be used. Brooks HI FI projectors Generation A term used to describe the number of times that the recorded audio signal has been copied. Limiter A device which reduces gain when the input voltage exceeds a certain level. Interface Any device that allows one unit to work, drive or communicate with another unit when they can...

A compressor with a very long release time used to keep the volume of the audio very constant. FOH (Front of House) Refers to the speakers that face toward the audience. Also called the "main" speakers. Brooks RM 909 reviews 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. IC Abbreviation of Integrated Circuit (A miniature circuit of many components that is in small, sealed housing with prongs to connect it into equipment). Brooks Hi Fi reviews Grouping 1) Controlling the gain of several individual channels with a Group Fader. 2) The mixing together of several individual audio signals to send a mixed signal out of the console to record a track on a multitrack tape machine. Ground Adapter Plug Adapts a three pronged electrical plug to a two pronged wall outlet. This bypasses ...

Vertical metal wires which sit vertically on the guitar neck. ADSR The letters A, D, S &R are the first letters of: Attack, Decay, Sustain and Release. These are the various elements of volume changes in the sounding of a keyboard instrument. Brooks RM 909 reviews Input Impedance The opposition to current flow by the first circuits of a device. Balanced input/output A "balanced" connection is one that has three wires to move the signal. One is a ground, and the other two (called conductors) carry signals of equal value. This is why they are called balanced. Low Z cables and connections are the most common example. Brooks HI FI projectors 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.
