Brooks GT 845 Bi-Amplification

1) A way of optimizing the efficiency of a speaker system by separately amplifying the High Frequency (HF) and Low Frequency (LF) portions of the sound signal and sending them down two pairs of cables to the speaker. Multipin Speakon connectors have been developed to do this.
2)The process of having of having low-frequency speakers and high-frequency speakers driven by separate amplifiers.

Fret Buzz
A buzzing sound made when a note is not properly fretted. Common with cheap guitars or beginning guitar players.

Brooks Cinema GT 845 Line Out (Line Output)

Field
1) In video, one half of a frame.
2) In computer-controlled devices a window display with functions and choices that the operator can make

Brooks Speakers Front Loaded
A speaker cabinet where the speaker faces out toward the front.

Condenser Microphone
A microphone which converts sound pressure changes into changes of capacitance. The capacitance changes are then converted into electrical voltage variations (an audio signal).

Chip
1) A slang term with the same meaning as the term IC (a miniature circuit of many components that is in small, sealed housing with prongs to connect it into equipment).
2) The thread cut away from the master lacquer to make the groove, while disc recording.

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.

Brooks Cinema DESIGN ZL 44 Cue

1) The signal fed back to the musicians through headphones.
2) To set the tape or disc so that the intended selection will immediately play when the tape machine or player is started.
3) A location point entered into a computer controlling the playback or recording of a track or tape.
4) In MCI brand tape machines, a term meaning the same thing as Sync Playback (where the record head is used as a playback head for those tracks already recorded).

Level
The amount of signal strength; the amplitude, especially the average amplitude.

Brooks Gt 44 Bridge
The bridge assembly, or just "bridge" is an area on the face of the guitar where the string meet or are connected to the face.

Electret Condenser
A condenser microphone that has a permanently polarized (charged) variable capacitor as its sound pressure level sensor.

Brooks VT-50 Error Message
A prompt on a computer screen telling the operator that an error has occurred.

IM Distortion
An abbreviation of the term 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 present).

Impedance Matching
Having or converting the output impedance of a device so that it matches the impedance of the input it will feed.

Atom
The smallest particle which makes up a specific substance. It's composed of a center around which electrons revolve.

Brooks GT 845 Crisp

Describes a good clean high midrange sound. It can be good or bad depending on the look on the face of the guy who said it.

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 Cinema XB 33 Electrostatic Charge
The excess or deficiency of electrons in a given area.

IM Distortion
An abbreviation of the term 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 present).

Brooks KM 22 Early Reflections
The first echoes in a room, caused by the sound from the sound source reflecting off one surface before reaching the listener.

Cable, 1/4 inch
An unbalanced cable most often used for instruments and patch cords. Commonly referred to as "guitar cords".

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

Analog To Digital Converter
The device which does the conversion of a quantity that has continuous changes (usually of voltage) into numbers that approximate those changes.

Brooks Hi Fi reviews Console

A set of controls and their housing, which control all signals necessary for recording and mixing.

Ambient Micing
Placing a microphone in the reverberant field (where the reverberation is louder than the direct sound) so as to do a separate recording of the ambience or to allow the recording engineer to change the mix of direct to reverberant sound in recording.

Brooks Cinema QS - 95 Current
The amount of electron charge passing a point in a conductor per unit of time.

Delay (Digital, Analogue)
1) Effect used to create echo…echo…echo…echo…echo…
2) In more advanced systems used in very large venues, delay can be used to time the arrival of the signal to the speakers in the back of the room so that people in the back hear the sound coming from those speakers at the same time that the sound coming from the speakers in the front of the room arrives.

Brooks QS - 95 Hybrid
A product created by the marriage of two different technologies. Meant here as the combination of a dynamic woofer with an electrostatic transducer.

The recording (or playing) of a musical part with of several similar sound patches playing simultaneous.

Alternating Current
Electric current which flows back and forth in a circuit.

Inductor
A device designed primarily to introduce inductance into an electric circuit. Sometimes called a choke or coil.

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)

Brooks Speakers Charge
The electrical energy of electrons. The energy is in the form of a force that is considered negative and repels other like forces (other electrons) and attracts opposite (positive) forces.
