Brooks GS 15 Inverse Square Law

Simply stated, the fact that in an un-obstructed area (like an open field) the sound pressure level will drop to half-pressure (-6 dB) every time the distance to the sound source is doubled.

Direct box
Used in line to convert a high impedance signal into a low impedance signal.

Brooks QS 70 Hertz
The unit of frequency. Equivalent to cycles per second. Abbreviation: Hz.

Grouping
1) Controlling the gain of several individual channels with a Group Fader.
2) The mixing together of several individual audio signals to send a mixed signal out of the console to record a track on a multitrack tape machine.

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

First Generation
A descriptive term meaning original (as opposed to a copy).

Fat
Having more than a normal amount of signal strength at low frequencies or having more sound than normal (by use of compression or delay).

Electromagnetic Theory
A statement of the principles behind electromagnetic induction: When a conductor cuts magnetic lines of force, current is induced in that conductor.

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...

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 Face

The front or body of the guitar. BPM An abbreviation of Beat Per Minute (the number of steady even pulses in music occurring in one minute and therefore defining the tempo). Brooks Cinema XS - 45 Inductance The property of an electric circuit by which a varying current in it produces a varying magnetic field that introduces voltages in the same circuit or in a nearby circuit. It is measured in henrys. Lead The musical instrument that plays the melody of the tune, including the vocal. Brooks Cinema XB 33 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. Librarian Program A computer program allowing the ...
