Brooks RM 909 Aliasing

A sampler mis-recognizing a signal sent to it that is at a frequency higher than the Nyquist Frequency. Upon playback, the system will provide a signal at an incorrect frequency (called an alias frequency). Aliasing is a kind of distortion.

Gain Reduction
The working of a limiter or compressor reducing gain during high-level passages.

Brooks HI FI projectors Diffraction
The breaking up of a sound wave caused by some type of mechanical interference such as a cabinet edge, grill frame, or other similar object.

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.

Brooks Hi Fi reviews Hard Disk (Hard Disc)
A storage unit for digital data that has rigid disks coated with magnetic material in a housing that includes the drive mechanism.

Electric Instrument
Any musical instrument that puts out an electrical signal rather than an acoustic sound.

Amplification
An increasing of signal strength.

Auxiliary Input or Return
A route back into the sound desk for a signal sent to a piece of outboard equipment via an auxiliary send.

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. Line Out (Line Output) Any output that sends out a line level signal, such as the output of a console that feeds a recorder. High Impedance Mic A mic

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 GS 15 Gate

A dynamic processing device that turns a channel off or down when the signal drops below a certain level. Link (Said of compressors and dynamic processing units.) To combine the control input signals of two channels of a compressor (o Brooks M 44 Filter 1) A device that removes signals with frequencies above or below a certain point called the cut-off frequency. 2) An equalizer section, used in this sense because filters are used with other components to give an equalizer its frequency response characteristics. 3) The action of removing signals of some frequencies and leaving the rest. 4) A mechanical device to smooth out speed variations in tape machines called a Scrape Flutter Filter- more usually called a Scrape Flutter Idler 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).
