Channel

A channel refers to an individual circuit that can be independently controlled.

Clamp-On Meter

Special ammeter with a non-invasive jaw that clamps around a single electrical conductor and will display how much current is flowing.

Coaxial Cable

A cable with one conductor completely surrounded by another conductor, separated by a dielectric. The two conductors being coaxial. Some types of coax cables use multiple conductors surrounding each other. Normally only the inner conductor carries a signal. The outer conductors [Braid] are used as a shield, or grounded. Coaxial Cable is normally used in RF transmission. The term Coaxial is normally shortened to Coax. Types of Coaxial Cable include: RG-6, RG-8, RG-11, RG-58, RG-59.

Constant Bit Rate

Constant bitrate (CBR) is a term used in telecommunications, relating to the quality of service. Compare with variable bitrate. When referring to codecs, constant bit rate encoding means that the rate at which a codec's output data should be consumed is constant. CBR is useful for streaming multimedia content on limited capacity channels since it is the maximum bit rate that matters, not the average, so CBR would be used to take advantage of all of the capacity.

Controller

A device that can turn the lights on and off on a dedicated network. It consists from four to 16+ output circuits.

Copyright

A copyright is a set of exclusive rights granted by a state to the creator of an original work or their assignee for a limited period of time in exchange for public disclosure of the work.

Copyright owners can license or permanently transfer or assign their exclusive rights to others.

Coro

Shorthand for Corrugated Plastic. Just like cardboard, but plastic and weatherproof.

CTB-16D

The Deluxe Controlled Triac Board - 16 Channels (CTB16D) is a 16 channel light controller that can operate independently, operate as the director unit in a multi-controller network or as an add-on unit of a larger synchronized network of controllers. The CTB16D was designed to be an excellent choice for standalone applications. Each of the 16 independent channels has a number of special effects such as dimming, ramping, twinkle and shimmer.

Without heatsinks installed the CTB16 can control up to 2 Amps per channel. With heatsinks properly installed it can control up to 8 Amps per channel. Maximum capacity of the card is 40 Amps. All connections are rated 20 amps for wire up to 12AWG.

Diode

An electrical device that will allow current to pass in only one direction. Consists of a cathode and an anode. A two-terminal semiconductor device used chiefly as a rectifier.

Dipole

A basic radio antenna that consists of two elements, each of equal length. The length of the elements is an algorithmic function of the frequency over which the broadcast is being made.

Director Card

The LOR DC-MP3 (Light-O-Rama Director Card with MP3 Player) is a powerful yet compact light show director. It is designed to control a network of Light-O-Rama (LOR) light controllers while simultaneously playing MP3 music files.

The unit is simple to operate. You insert a SD memory card and plug it in. It will then run the show.

DMX

Digital Multiplex. A lighting control protocol standard developed to handle communications between commercial (usually entertainment, such as theater or music events) lighting control boards and the individual devices, such as lekos (elliposoidals), fresnels, moving lights, strip lights or DJ effect lights. DMX allows up to 512 devices to be attached, daisy-chain, to one wire, each controlled individually.
