Brooks Cinema Projectors 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.

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

Brooks KS-55 Effects
Electronic boxes (usually rack mounted) added to a PA system to subtly change and enhance the signals going through it. Examples include; Reverb, Delay, Compressor, Chorus.

Electricity
Electrical current (the amount of electron charge passing a point in a conductor per unit of time) or voltage (the force pushing electrons to obtain electrical current).

Brooks QS 70 Bi-Directional Pattern
A microphone pick up pattern which has maximum pick up directly in front and directly in back of the diaphragm and least pick up at the sides.

Ambient Field
A term with the same meaning as the term Reverberant Field (the area away from the sound source where the reverberation is louder than the direct sound).

Electrons
Negatively charged particles, which revolve around the centre of atoms. The movement of such electrons down a conductor causes electrical current.

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