Brooks GT 845 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.

Chord
Three or more musical pitches sung or played together.

Brooks Audio Design QS 70 Acoustic Echo Chamber
A room designed with very hard, non-parallel surfaces and equipped with a speaker and microphone; dry signals from the console are fed to the speaker and the microphone will have a reverberation of these signals that can be mixed in with the dry signals at the console.

Echo Return
An input of the console, which brings back the echo (reverberation) signal from the echo chamber or other echo effects device.

Brooks Audio Design SS 81 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).

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.

Cycle
1) An alternation of a waveform which begins at a point, passes through the zero line, and ends at a point with the same value and moving in the same direction as the starting point.
2) On a Solid State Logic Console, a command to have the console computer control the tape machine to play and replay a certain section of the tape.

Insulator
A substance such as glass, air, plastic, etc., that will (for all practical purposes) not conduct electricity.

Broom RM 909 Final Mix

The two track stereo master tape which was mixed from the multitrack master. Barrier Micing A method of placing the head of a microphone as close as possible to a reflective surface, preventing phase cancellation. Brooks Cinema Projectors Corner Frequency Same as Cut-Off Frequency (the highest or lowest frequency in the pass band of a filter). (NOUN) Cable, 1/4 inch An unbalanced cable most often used for instruments and patch cords. Commonly referred to as "guitar cords". Brooks GT 845 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. Crosstalk Leakage of an audio signal into a channel that iris not intended to be in, from an adjacent or nearby channel. Level The amount of signal strength; the am

Brooks HI FI projectors In

Short For "in the circuit," in other words "active." Audio Most often referring to electrical signals resulting from the sound pressure wave being converted into electrical energy. Brooks Hi Fi speakers Link (Said of compressors and dynamic processing units.) To combine the control input signals of two channels of a compressor (o Corner Frequency Same as Cut-Off Frequency (the highest or lowest frequency in the pass band of a filter). (NOUN) Brooks Hi Fi reviews Boost To increase gain, especially to increase gain at specific frequencies with an equalizer. Cut-Off Frequency (Turnover Frequency) 1) The highest or lowest frequency in the pass band of a filter. 2) The highest or lowest frequency passed by an audio device (the cut-off frequency is usually considered to be the first frequency to be 3 dB lower than a reference frequency in the middle of the bandwidth of the device) Dynamic Mic Robust type of microphone which picks up
