BNO Speakers Gain Control

A device that changes the gain of an amplifier or circuit, often a knob that can be turned or a slide that can be moved up arid down.

Level
Sets output volume of individual PA input channels. Usually positioned as sliders at the bottom of the soundboard.

BNO Acoustics 6k-52 Headroom
1) The level difference (in dB) between normal operating level and clipping level in an amplifier or audio device.
2) A similar level difference between normal tape operating level and the level where the distortion would be 3%.
3) The difference, in decibels, between the peak and RMS levels in program material.

Imaging
To make a representation or imitation of the original sonic event.

BNO Acoustics XR-90 Capacitor
1) A device consisting of two or more conducting plates separated from one another by an insulating material and used for storing an electrical charge. Sometimes called a condenser.
2) An electronic device that is composed of two plates separated by an insulator.

Haas Effect
Simply stated, a factor in human hearing where delay has a much bigger effect on human perception of direction than level does.

Amplification
An increasing of signal strength.

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