BNO Acoustics LK-61 Central Processing Unit

1) The main "brain" chip of a computer that performs the calculations and execution of instructions.
2) The main housing of a computer that contains the "brain" chip as opposed to other pieces of the computer system such as keyboards, monitors, etc.

Beat
1) The steady even pulse in music.
2) The action of two sounds or audio signals mixing together and causing regular rises &.falls in volume.

BNO Acoustics QS-4 DC
Abbreviation for direct current.

Cable, TRS
A less common balanced cable that has 3 different contacts on its 1/4 inch connectors. Most headphone jacks are a good example of a TRS (Tip-Ring-Sleeve) connector. These are sometimes used instead of the more common XLR connection.

BNO Acoustics GK-3 Inductance
The property of an electric circuit by which a varying current in it produces a varying magnetic field that introduces voltages in the same circuit or in a nearby circuit. It is measured in henrys.

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.

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

Crossover
1) A route leading from one side of the stage to the other, out of the audiences view.
2) An electronic filter in a sound system that routes sound of the correct frequency to the correct part of the speaker system. Different speakers handle high frequencies (tweeters) and low frequencies (woofers). Sometimes known as a crossover network. An active crossover splits the signal from the mixing desk into high, mid and low frequencies which are then sent to three separate amplifiers.
3) An electrical circuit that divides a full bandwidth signal into the desired frequency bands for the loudspeaker components.
