Brooks KM 77 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)

Line
1) Short for line level.
2) A cable.

Brooks Cinema TZ 505 Amplifier
Sound equipment that converts the low voltage, low current signal from a tape deck, mixer etc. into a higher current signal suitable for driving speakers. See Power Amplifier, Crossover.

Feed
To send an audio or control signal to.

Brooks XB 22 Error Message
A prompt on a computer screen telling the operator that an error has occurred.

Capo
A clamp-like device that is placed vertically across the guitar neck. It is used to change the pitch of the guitar, acting as a moveable nut.

Formant
An element in the sound of a voice or instrument that does not change frequency as different pitches are sounded.

Effects
1) Various ways an audio signal can be modified by adding something to the signal to change the sound.
2) Short for the term Sound Effects (sounds other than dialogue, narration or music like door closings, wind, etc. added to film or video shots).

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 Speakers reviews Comb Filter 1) The frequency response achieved by mixing a direct signal with a delayed signal of equal strength especially at s

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
