Brooks Speakers Bi-Directional Pattern

A microphone pick up pattern which has maximum pick up directly in front and directly in back of the diaphragm and least pick up at the sides.

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.

Brooks Cinema DESIGN ZL 44 Line Level
1) An amplified signal level put out by an amplifier and used as the normal level that runs through the interconnecting cables in a control room.
2) A low level signal such as the signal in a guitar cord. Most parts of a PA require a line level signal. Remember, however, that speaker outputs are not line level. Plugging speaker outs into line ins will result in damage to the equipment

Intermodulation Distortion
Distortion caused by one signal beating with another signal and producing frequencies that are both the sum and the difference of the original frequencies.

BROOKS AUDIO DESIGN Electrostatic Charge
The excess or deficiency of electrons in a given area.

Foldback
A European term for the signal sent to the stage monitors in a live performance.

Audio
Most often referring to electrical signals resulting from the sound pressure wave being converted into electrical energy.

Circuit
1) One complete path of electric current.
2) Similar to definition 1, but including all paths and components to accomplish one function in a device.

Brooks XB 33 Hybrid

A product created by the marriage of two different technologies. Meant here as the combination of a dynamic woofer with an electrostatic transducer. Haas Effect Simply stated, a factor in human hearing where delay has a much bigger effect on human perception of direction than level does. Brooks Cinema RM 909 Coax Two-conductor cable consisting of one conductor surrounded by a shield. 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 XR 607 Bass 1) The lower range of audio frequencies up to approximately 250 Hz. 2) Short for Bass Guitar. 3) Lower end of the musical scale. In acoustics, the range (below about 200 Hz) in which there are difficulties, principally in the reproduction of sound, due to the large wavelengths involved. 4) The lower frequencies. 5) On the soundboard this should refer to the bass guitar channel, not

Brooks Cinema DESIGN ZL 44 reviews Formant

An element in the sound of a voice or instrument that does not change frequency as different pitches are sounded. Board 1) Another, less formal, term for Console. 2) A set of controls and their housing which control all signals necessary for recording and for mixing. 3) A slang shortening of the term Keyboard Instrument. Brooks Gt 44 reviews Impedance Matching Having or converting the output impedance of a device so that it matches the impedance of the input it will feed. Acoustic Amplifier The portion of the instrument which makes the vibrating source move more air or move air more efficiently; this makes the sound of the instrument louder. Examples of acoustic amplifiers include: 1) The body of an acoustic guitar, 2) The sounding board of a piano, 3) The bell of a horn and 4) The shell of a drum.

Brooks VT-50 Bank

1) A collection of sound patches (data as to the sequence and operating parameters of the synthesizer generators and modifiers) in memory. 2) A group of sound modules as a unit. AC 1) Abbreviation for alternating current. 2) An abbreviation of the term Alternating Current (electric current which flows back and forth in a circuit; all studio signals running through audio lines are AC). Brooks Cinema Projectors Input/Output Module A set of controls, on one housing, for an in-line console that has two channels (one for recording and one for monitoring) and has controls for all console sections. Linearity The extent to which any signal handling process is accomplished without amplitude distortion. Brooks Cinema QS - 95 Impedance Matching Having or converting the output impedance of a device so that it matches the impedance of the input it will feed. Crossover (Crossover Network) A set of filters that "split" the audio signal into two or more
