1) To add sounds into a mix or recording that have no synchronization. 2) An application of this where a performance from one part of a tune is recorded and then recorded back into the recording at a different time in the recording. In Port A jack on a MIDI device or computer that will accept an incoming data signal. Brooks Hi Fi speakers Centre Frequency The frequency of the audio signal that is boosted or attenuated most by an equalizer with a peak equalization curve. Dry Describes a sound coming from the PA with no effects on it. Brooks RM 909 reviews Delay 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. IC Abbreviation of Integrated Circuit (A miniature circuit of many components that is in small, sealed housing with prongs to connect it into equipment). Lead Sheet A written chart showing the m

1) In video, one half of a frame. 2) In computer-controlled devices a window display with functions and choices that the operator can make Effects 1) Various ways an audio signal can be modified by adding something to the signal to change the sound. 2) Short for the term Sound Effects (sounds other than dialogue, narration or music like door closings, wind, etc. added to film or video shots). Brooks RM 909 reviews Far Field The area from 3 feet away from the sound source up to the critical distance. LED 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 Hi Fi speakers Balance 1) The relative level of two or more instruments in a mix, or the relative level of audio signals in the channels of a stereo recording. 2) To make the relative levels of audio signals in the channels of a stereo recording even. Arc The visible sparks generated by an electrical discha

The way in which the gain varies in the stages or sections of an audio system. Gain Reduction The working of a limiter or compressor reducing gain during high-level passages. Brooks RM 909 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. Face The front or body of the guitar. Brooks RM 909 reviews LED 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. Charge The electrical energy of electrons. The energy is in the form of a force that is considered negative and repels other like forces (other electrons) and attracts opposite (positive) forces. Formant An element in the sound of a voice or instrument that does not change frequency as different pitches are sounded. Compact Disc, Read Only Memory CDROM A Compact Disc

1) An Echo Chamber (a room designed with very hard, non-parallel surfaces equipped with a speaker and microphone so that when dry signals from the console are fed to the speaker, the microphone will have a reverberation of these signals that can be mixed in with the dry signals at the console). 2) A program in a delay/reverb effects device that simulates the sound of an Echo Chamber. Amplification An increasing of signal strength. Brooks Hi Fi speakers Integrated Circuit (IC) A miniature circuit of many components in a small, sealed housing with prongs to connect it into equipment.
