Pre-Amp - A preamp amplifies a low level signal to normal line level before it is processed further and amplified further. It is generally used to give a boost to signals coming from Mics, Turntables and other . Used . audio equipment that has no amperage to the signal it produces.
. Used . ...
Dichroic - In optics, the term dichroic has two related but distinct meanings. A dichroic material is one which either causes light to be split up into distinct beams of different wavelengths (colours), or, one . Used . in which light rays having different polarizations are absorbed by different amounts.
The original meaning of dichroic (from the Greek dikhroos, two-coloured) refers to any optic. Used . al device which can split a beam of light into two beams with differing wavelengths. Such devices include mirrors and filters, usually treated with optical coatings, which are designed to reflect light over a ...
Lighting instruments - There are a variety of instruments frequently used in the theater. Although they vary in many ways they all have the following four basic components in one form or another...
* Box/Housin. Used . g - a metal or plastic container to house the whole instrument and prevent light from spilling in un-wanted directions.
* Source of light (bulb or lamp).
* Lens or opening - the g. Used . ap in the housing where the light is intended to come out.
* Reflector - behind or around the light source in such a way as to direct more light towards the lense or opening.

Address - In computer science, a memory address is a unique identifier for a memory location at which a CPU or other device can store a piece of data for later retrieval. In modern byte-addressable computers, e. Used . ach address identifies a single byte of storage; data too large to be stored in a single byte may reside in multiple bytes occupying a sequence of consecutive addresses. Some microprocessors . Used . were designed to be word-addressable, so that the typical storage unit was actually larger than a byte. Examples include the Texas Instruments TMS9900 and the National Semiconductor IMP-16, both of which used ...
Pattern - Pattern refers to the shape, quality and evenness of a lamp's output. The pattern of light an instrument makes is largely determined by three factors. The first are the specifics of the bulb, reflecto. Used . r and lens assembly. Different mounting positions for the bulb (axial, base up, base down), different sizes and shapes of reflector and the nature of the lens (or lenses) being used can all a. Used . ffect the pattern of light. Secondly, the specifics of how the lamp is focused affect its pattern. In Ellipsoidal Reflector Spotlights (ERS) and their derivatives (see below), there are two beams of light emit...
