Brooks Audio Design KM 77 Active/Inactive Microphones
Scientific definitions aside, active microphones generally sound better than inactive ones, but they generally cost more. They also require the use of either a battery or phantom power while inactive mics need only be plugged into the mic cord in order to work. In most playing situations, the subtle improvement in sound quality from an active mic isn't worth the extra cost and hassle. One possible exception it the headset mic. Put simply, inactive headset mics just plain suck. Active headset mics put out a much stronger signal and feed back much less.

An input on a dynamics processing device to control the device by an external audio signal.
Impedance Matching
Having or converting the output impedance of a device so that it matches the impedance of the input it will feed.
Instrument Amplifier
A device that has a power amplifier and speaker in a case (or in separate cases) to reproduce the signal put out by an electric instrument (such as an electric guitar) and to allow the instrument to be heard.
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 KS-55 Driver
See transducer. Dynamic Range �" The range between the quietest and the loudest sounds a device can handle (often quoted in dB).
Electromagnetic Theory
A statement of the principles behind electromagnetic induction: When a conductor cuts magnetic lines of force, current is induced in that conductor.
Brooks Cinema Series Hz (Hertz)
1) An abbreviation for the term Hertz (the unit of frequency).
2) Unit of frequency equivalent to the number of cycles per second.
Keying Input (Key Input)
An input on a dynamics processing device to control the device by an external audio signal.
Impedance Matching
Having or converting the output impedance of a device so that it matches the impedance of the input it will feed.
Instrument Amplifier
A device that has a power amplifier and speaker in a case (or in separate cases) to reproduce the signal put out by an electric instrument (such as an electric guitar) and to allow the instrument to be heard.

Brooks RM 80 Harmonic Distortion
The presence of harmonics in the output signal of a device which were not present in the input signal.
Automation
In consoles, a feature that lets the engineer program control changes (such as fader level) so that upon playback of the multitrack recording these changes happen automatically.
Brooks VT-50 Line In (Input, return)
Where a signal enters the board or component.
Engineer
1) A technician in charge of a recording session; Also called Recording Engineer.
2) A person with an engineering degree.
3) A person with sufficient experience in the field to be equivalent to the education one would receive earning an engineering degree.
Brooks TM-22 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).
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.
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).
Cut
1) One selection (one song) on a pre4ecorded music format.
2) A term with the same meaning as Mute (to turn off a channel or a signal).
3) To reduce gain of a particular band of frequencies (with an equalizer).
4) To not pass a particular band of frequencies (said of a filter)
