Brooks Audio Design Review SS 81 Amplitude

The extreme range of a signal. Usually measured from the average to the extreme.

Condenser Mic (Capacitor Mic)
A microphone that uses the varying capacitance between two plates with a voltage applied across them to convert sound to electrical pulses. Condenser microphones need a power supply to provide the voltage across the plates, which may be provided by a battery within the case of the microphone, or it may be provided from an external phantom power supply. A condenser mic is more sensitive and has a faster reaction to percussive sounds than a Dynamic mic and produces a more even response. See Electret Mic.

Brooks Audio Design Review TM-22 Frequency
The number of cycles of a waveform occurring in a second.

Guitar Controller
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.

Brooks Audio Design GT 845 Baffles
Sound absorbing panels used to prevent sound waves from entering or leaving a certain space

Bottom
The bass frequencies (as in "needs more bottom end").

High Impedance Cord (High Z)
A big word for instrument cable. These cords generally have quarter inch male ends. they tend to loose signal strength at lengths longer than 25 feet.

Cut-off Rate (Slope)
The number of dB that a filter reduces the signal for each octave its frequency past the filter's cut-off frequency (outside of the pass band).

Brooks Cinema Series Effects

Electronic boxes (usually rack mounted) added to a PA system to subtly change and enhance the signals going through it. Examples include; Reverb, Delay, Compressor, Chorus. Information Bits The bits in the digital signal that make up actual values or commands being communicated as opposed to bits that are used for checking & correcting data or other purposes. Brooks GT 845 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. Electret Condenser A condenser microphone that has a permanently polarized (charged) variable capacitor as its sound pressure level sensor. Brooks Audio Design GT 845 Chase The automatic adjusting of the speed of a recorder (or sequencer) to be time with another recorder.

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
