Brooks RM 909 reviews Hertz The unit of frequency. Equivalent to cycles per second. Abbreviation: Hz. 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 RM 909 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. Electronics 1) On a tape machine, the housing for and the channel circuitry which processes the signal to be fed to the

A double grounding of a line or electronic device at two different "ground" points of differing voltage. Capo A clamp-like device that is placed vertically across the guitar neck. It is used to change the pitch of the guitar, acting as a moveable nut. Brooks HI FI projectors 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. Icon A visual picture or symbol on a computer screen that represents a file, program or disc that can be used. Brooks RM 909 Keynote Number A number assigned to each key of a synthesizer or controller keyboard that is transmitted in the MIDI signal. Condenser An older term meaning the same thing as Capacitor (an electronic device which is composed of two plates separated by an insulator and can store charge) but sill in common use when referring to a microphone's active element. Active Crosso

The First session in recording an audio production to record the Basic Tracks. Compander Outboard sound equipment. Combination of a Compressor and an Expander. Brooks Hi Fi reviews Ground Lift A switch that breaks the connection between the ground point in one circuit and the ground point in another circuit. Buss (Bus) A wire carrying signals to some place, usually fed from several sources. Brooks Hi Fi speakers Instrument Out Direct Feeding the output of an electric instrument (like an electric guitar) to the recording console or tape recorder without using a microphone. High Frequencies The audio frequencies from 6000 Hz and above. Flamenco A style of music with roots in Spanish and Arabic culture. Electricity Electrical current (the amount of electron charge passing a point in a conductor per unit of time) or voltage (the force pushing electrons to obtain electrical current).

Another name for Bass Drum (the largest drum in the Drum Kit which puts out bass frequencies and is played with a foot pedal). Hard Disk Recording The recording of digital audio onto a hard disc. Brooks RM 909 reviews Ground Loop A double grounding of a line or electronic device at two different "ground" points of differing voltage. 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). Brooks HI FI projectors AES/EBU Professional Interface A standard for sending and receiving digital audio adopted by the Audio Engineering Society and the European Broadcast Union. Group Master A slide control used to send out a control voltage to several VCA faders in individual channels, thus controlling the gain of several channels. Electronics 1) On a tape machine, the housing for and the channel circuitry which

1) Digital sound storage medium. Provides a high quality source of music, sound effects etc. Also used as a playback medium for sound effects etc. by large theatres with long running shows, although CDR (Recordable CD) is becoming more affordable by the day. 2) An abbreviation of the term Compact Disc (a small optical disk with digital audio recorded on it). Cancellation A shortening of the term Phase Cancellation (the energy of one waveform significantly decreasing the energy of another waveform because of phase relationships at or close to 180 degrees). Brooks RM 909 reviews Layering The recording (or playing) of a musical part with of several similar sound patches playing simultaneous. First Generation A descriptive term meaning original (as opposed to a copy). Brooks HI FI projectors Absorption Short for the term Acoustical Absorption (quality of a surface or substance to take in, not reflect, a sound wave). Chase The automatic adjusting of the spe

Frequency Shift Key / FSK The full name for FSK (A simple clock signal that can be used to run a sequencer in time with an audio tape). Brooks HI FI projectors 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) Amplifier Sound equipment that converts the low voltage, low current signal from a tape deck, mixer etc. into a higher current signal suitable for driving speakers. See Power Amplifier, Crossover. Brooks Hi Fi reviews Dynamic Mic Robust type of microphone which picks up the sound on a diaphragm connected to a coil of wire which moves within a magnet. An alternating current is induced into the wire which provides the electrical output. Most dyn
