BNO Acoustics Speakers Audio

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

Expansion
The opposite of compression; for example, an expander may allow the signal to increase 2 dB every time the signal input increased by 1 dB.

BNO Acoustics QT-5 Filter
1) A device that removes signals with frequencies above or below a certain point called the cut-off frequency.
2) An equalizer section, used in this sense because filters are used with other components to give an equalizer its frequency response characteristics.
3) The action of removing signals of some frequencies and leaving the rest.
4) A mechanical device to smooth out speed variations in tape machines called a Scrape Flutter Filter- more usually called a Scrape Flutter Idler

Delay
Outboard sound equipment that can momentarily stores a signal being sent to part of a P.A. system so that delayed reinforced sound reaches the audience at the same time as live sound from the stage.

BNO Acoustics XR-90 Frequency Range
The range of frequencies over which an electronic device is useful or over which a sound source will put out substantial energy.

Input/Output Module
A set of controls, on one housing, for an in-line console that has two channels (one for recording and one for monitoring) and has controls for all console sections.

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

CPU
Abbreviation of Central Processing Unit (The main "brain" chip of a computer or the main housing of a computer that contains the "brain" chip).
