Number of terms: 32421
Number of blossaries: 0
Company Profile:
Electronic device which allows display of script for speaker to read during presentation.
Industry:Convention
Electrically or manually rotating platform.
Industry:Convention
Electrical relay that is timed to activate further mechanisms after it has been itself activated.
Industry:Convention
Electrical on/off switch used directly in wiring to control, by make or break, the flow of current.
Industry:Convention
Electrical device used to interrupt or sustain flow of current. Commonly used in low-voltage systems for programmed effects.
Industry:Convention
Electrical device composed of coils of wire (inductors) and electrical capacitors, that separates audio frequency bands by filtering action and routes them to different places (such as a woofer and tweeter). The frequency of the crossovers action is determined by the value of the electronic components inside, and by the loudspeaker drivers impedance in ohms, which implies that replacing a 16-ohm driver in a particular system with an 8-ohm driver will change the crossover frequency. In such a case, the frequency will rise an octave and the shape of the crossover frequency response slopes will be distorted.
Industry:Convention
Electrical component made to resist current flow.
Industry:Convention
Electrical cart used for driving around show floor.
Industry:Convention
Electrical characteristic of inductors and of capacitors, opposing the flow of A. C. Electricity. Reactance is measured in ohms and may be negative producing what is called an imaginary part of an impedance. Loudspeakers, for example, can be highly reactive and, under certain circumstances with certain signals, can feed 50 amperes or more back into the power amplifier driving them.
Industry:Convention
Doubling or halving of frequency. The numerical interval, for example, between 440 Hz and 880 Hz or 220 Hz is an octave.
