Compressor
1) Effect used to squash the sound together. Used properly, it can take the edge off or your sound. Used improperly, it can take the life right out of your system and make it sound like an MTV mix.
2) A piece of sound processing equipment that ensures all wanted signals are suitably placed between the noise and distortion levels of the recording medium. It evens out the unwanted changes in volume you get with close-miking, and in doing so, adds punch to the sound mix. A Limiter is used to stop a signal from exceeding a preset limit. Beyond this limit, the signal level will not increase, no matter how loud the input becomes. A Limiter is often used to protect speaker systems (and human ears) by preventing a system from becoming too loud.

Efficiency
The acoustic power delivered for a given electrical input. Often expressed as decibels/watt/meter (dB/w/m). ESL �" Abbreviation for electrostatic loudspeaker.

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 Cinema TZ 505 Capacitance
That property of a capacitor which determines how much charge can be stored in it for a given potential difference between its terminals, measured in farads, by the ratio of the charge stored to the potential difference.

Kick (Kick Drum)
Another term for Bass Drum.

Brooks GT 44 Generation
A term used to describe the number of times that the recorded audio signal has been copied.

Key
The control of a dynamics processing device by an external audio signal.

Analog (Analogue)
Representative, continuous changes that relate to another quantity that has a continuous change.

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 GS 15 Bottom

The bass frequencies (as in "needs more bottom end").

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 TM-22 Envelope
1) How a sound or audio signal varies in intensity over a time span.
2) How a control voltage varies in level over time controlling a parameter of something other than gain or audio level.

Bit
The smallest unit of digital information representing a single "0" or 1.

Brooks Cinema XR 607 Feedback Control
The control on a delay line or delay effects device that controls the amount of feedback.

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

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.

LED
A light that allows current to flow in one direction only and emits light whenever a voltage of a certain level or beyond is applied to it.

Brooks SS 81 Flamenco

A style of music with roots in Spanish and Arabic culture.

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

Brooks BA 71 House Sync
A synchronization signal such as SMPTE time code that is used by all recorders in the control room.

Chase
The automatic adjusting of the speed of a recorder (or sequencer) to be time with another recorder.

Brooks M 44 Clipping
Distortion of a signal by its being chopped off. An overload problem caused by pushing an amplifier beyond its capabilities. The flat-topped signal has high levels of harmonic distortion which creates heat in a loudspeaker and is the major cause of loudspeaker component failure.

Lift
1) To boost gain of audio at a particular band of frequencies with an equalizer.
2) An elevation device in the star trek series of TV programs.

Ground
In electronics, a place (terminal) that has zero volts.

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

Brooks BA 71 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.

Full Step
A change in pitch that occurs when moving up or down two piano keys

Brooks SS 81 Guitar Controller
An electric guitar or device played like an electric guitar that puts out MIDI signals that can be used to control synthesizers and sound modules.

Amplitude
The height of a waveform above or below the zero line.

Brooks KM 77 Audio
Most often referring to electrical signals resulting from the sound pressure wave being converted into electrical energy.

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.

File
A collection of digital data stored in a computer's memory bank or on a floppy disc.

Amplifier
A device which increases the amplitude (level) of an electrical signal (making it louder).

Coax
Two-conductor cable consisting of one conductor surrounded by a shield.

Brooks Cinema ZL 44 Jack Bay
A series of jacks which have connections for most of the inputs and outputs of the equipment in the control room.

High-Pass Filter
A device that rejects signals that are below a certain frequency (called the cut-off frequency) and passes signals with frequencies that are higher.
