Compression and Dynamics
- Compression is the reduction of the dynamic range of a sound to avoid unintentional changes and increases in the amplitude. Compression is generally used to make an audio signal sound louder without i. Used . ncreasing its peak amplitude. By compressing or limiting the peak signals, it becomes possible to increase the overall volume of the signal without exceeding the dynamic limits of a device or. Used . medium. This causes quiet sounds to become louder, while louder sounds remain unchanged....Ellipsoidal
- Ellipsoidal is the name for a type of theatrical light, getting the name from the ellipsoidal reflector used to intensify the light of a back-loading lamp through the barrel and lens. Ellipsoidals are. Used . used for their strong, well-defined light and their versatility.
Characteristics of an ellipsoidal lighting unit include:
* An adjustable barrel, allowing a lightin. Used . g designer to change the size and focus of the light thrown by the unit by changing the distance between the mirror and the lens or lenses
* A set of brackets on the end of the barrel for the insertion o...Staging
- Staging is the process and art of selecting, designing, or modifying the performance space for a given purpose, be it theatrical, television, film or concert production. . Used . . Used . ...Color
- Color temperature is measured in kelvins, and gel colors are organized by several different systems maintained by the color manufacturing companies. The apparent color of a light is determined largel. Used . y by the gel color given it, but also in part by the power level the lamp is being run at and the color of material is it to light. As the percentage of full power a lamp is being run at drop. Used . s, the tungsten filament in the bulb glows orange instead of more nearly white. This is known as amber drift or amber shift. Thus a 1000-watt instrument at 50% will appear far more orange than a 500-watt instrAmpere
- The ampere (symbol: A) is the SI base unit of electrical current equal to one coulomb per second. It is named after André-Marie Ampère, one of the main discoverers of electromagnetism.
Th. Used . e ampere is that constant current which, if maintained in two straight parallel conductors of infinite length, of negligible circular cross-section, and placed 1 metre apart in vacuum, would . Used . produce between these conductors a force equal to 2×10–7 newton per metre of length....
