- Company Profile:
Device which converts one form of energy directly into another form of energy. Loudspeakers, microphone and motors are transducers which convert motion into electricity or vice versa. Light-emitting diodes and solar cells are transducers that convert electricity to light or vice versa, etc.
Industry:Convention
Diagram, drawn to scale, indicating placement on stage of artists equipment, props, microphones, etc.
Industry:Convention
Device which allows the patching of program signal into or receives program material from telephone lines.
Industry:Convention
Device used to isolate or to raise or lower an A. C. Voltage from its input to its output. A typical transformer may consist of two separate coils of wire wound on a magnetic steel score. When an A. C. Current passes through the input coil (primary) it produces an alternative magnetic field in the core, which in turn produces current flow in the output coil (secondary). By winding, a greater number of coil turns for the secondary winding, the input voltage is raised at the output; by using fewer secondary turns, the output voltage is lowered. An isolation transformer uses the same number of turns for primary and secondary, maintaining the same input voltage at the output while severing the electrical connection of the two coil windings.
Industry:Convention
Device used to create moving effects such as clouds, flames, waves, etc.
Industry:Convention
Device used in acoustic studies to analyze sound energies in a room as they occur and print them out for later study.
Industry:Convention
Device used for starting or stopping the flow of beverage from a container, such as a keg.
Industry:Convention
Device that oscillates. Sound is the oscillation of air caused by a mechanical oscillation such as that from a moving piano string or drum head. An electronic oscillator is a device containing circuits designed to produce electrical oscillations that are maintained, usually at a constant amplitude, and may have other specific characteristics that suit them for use as circuit test signals.
