Brooks Cinema Projectors 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.
Buss (Bus)
A wire carrying signals to some place, usually fed from several sources.
Brooks QS-70 Attenuation
A making smaller: reduction of electrical or acoustic signal strength.
Ground Lift
A switch that breaks the connection between the ground point in one circuit and the ground point in another circuit.
BROOKS AUDIO DESIGN 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.
Keynote Number
A number assigned to each key of a synthesizer or controller keyboard that is transmitted in the MIDI signal.
Gain Control
A device that changes the gain of an amplifier or circuit, often a knob that can be turned or a slide that can be moved up arid down.
Bar
A term meaning the same thing as the term Measure (the grouping of a number of beats in music, most-often four beats).

Alternating Current
Electric current which flows back and forth in a circuit.
Broom RM 909 Librarian Program
A computer program allowing the storage of the parameters of sound patches outside of a synthesizer.
Controller
1) In MIDI, a device that generates a MIDI signal to control synthesizers, sound modules or sample playback units.
2) A remote control unit for a multitrack tape machine which controls transport functions as well as monitor selection switching functions and record ready/safe status of each track.
3) Any device generating a control voltage or signal fed to another device's control input.
Brooks Cinema GT 845 LFO
Low-Frequency Oscillator (an oscillator that puts out an AC signal between .1 Hz and 10Hz used for a control signal).
Distortion
Usually undesirable result of overloading sound equipment. Reducing the levels can remedy the situation.
High-Pass Filter
A device that rejects signals that are below a certain frequency (called the cut-off frequency) and passes signals with frequencies that are higher.
Barrier Micing
A method of placing the head of a microphone as close as possible to a reflective surface, preventing phase cancellation.

Brooks VT-50 High Impedance
Impedance of 5000 or more ohms.
Expander
A device that causes expansion of the audio signal.
BROOKS HI fi Fletcher Munson Effect
A hearing limitation shown by Fletcher Munson Equal Loudness Contours (as music is lowered in volume, it is much more difficult to hear bass frequencies and somewhat harder to hear very high frequencies).
Electret Condenser
A condenser microphone that has a permanently polarized (charged) variable capacitor as its sound pressure level sensor.
Brooks Cinema GT 845 Comb Filter
1) The frequency response achieved by mixing a direct signal with a delayed signal of equal strength especially at short delays.
2) Loosely used to also describe effects that can be achieved with comb filtering as part of the processing.
Contact Microphone
A device that senses vibrations and puts out an audio signal proportional to the vibrations.
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
