BNO Acoustics Speakers Fade

1) A gradual reduction of the level of the audio signal.
2) A gradual change of level from one pre-set level to another.

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.

BNO Acoustics TR-12 FOH (Front of House)
Refers to the speakers that face toward the audience. Also called the "main" speakers.

Electret Mic
A condenser microphone where the capacitor plates are given a charge during manufacture which they retain, therefore requiring no external power supply.

BNO Acoustics QT-5 Aliasing
A sampler mis-recognizing a signal sent to it that is at a frequency higher than the Nyquist Frequency. Upon playback, the system will provide a signal at an incorrect frequency (called an alias frequency). Aliasing is a kind of distortion.

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

Frequency Response
How sensitive an electronic device (mic, amplifier, speaker, etc.) is to various frequencies; often communicated with a graph.

Amplitude
The extreme range of a signal. Usually measured from the average to the extreme.
