Protocol - In computing, a protocol is a convention or standard that controls or enables the connection, communication, and data transfer between two computing endpoints. In its simplest form, a protocol can be . Used . defined as the rules governing the syntax, semantics, and synchronization of communication. Protocols may be implemented by hardware, software, or a combination of the two. At the lowest leve. Used . l, a protocol defines the behavior of a hardware connection.

Protocols should be distinguished from technical standards, which variously specify how to build a computer or related hardware device,...

Digital Projection - A digital projection display system is a computerized display that projects an image, often a logo, on a screen, building or other architectural features like the court in a sports arena. Such devices. Used . are commonly used in presentations or as promotional devices. These displays use a very bright light to project the image, and can generally correct any curves, blurriness, and other inconsi. Used . stencies in the image....

Hertz - A unit of measure for frequency generally applied to waveforms, one Hertz is equal to one cycle in one second. It is abbreviated Hz so that 100 Hz would be 100 cycles per second. However, the unit m. Used . ay be applied to periodic events other than waveforms like the second hand on a clock, which would cycle at 1 Hz, or a human heart that may beat at 1.2 Hz. Named after the German physicist H. Used . einrich Rudolf Hertz, the name was established in 1930, but did not replace the term cycles per second until the 1970s.

Dimmer - Dimmers are devices used to vary the voltage running to a light. By decreasing or increasing the voltage to the lamp it is possible to vary the intensity of the lamp. Changes in intensity are called “.

Used Line Array Speakers

Line array speakers make up a loudspeaker system to create a sound source that produces an evenly distributed sound output. The driver of each line array element is close enough to the driver of the next element to create constructive interference. The resulting sound waves go farther than sound waves from traditional loudspeakers. Line array systems date back to the early days of research in acoustics. Many old town halls and public venues still have old line source boxes which were found to project voice well though they are much smaller than horn-loaded speakers. These days, line array speakers use different drivers for high-, mid- and low-frequency passbands that must be in line. Each enclosure must be set up closely to form columns composed of these drivers. To increase the frequency range and maximum sound pressure, the number of drivers per enclosure must be increased. The orientation of line array speakers may vary. Vertical arrays are excellent for focusing sound at audiences without wasting output energy on ceilings or empty air above the audience because of its very narrow vertical output with a normally-wide horizontal pattern. On the other hand, horizontal line arrays have a very narrow horizontal output with a tall vertical pattern. For hanging concert speakers which are usually part of a concert reinforcement system, enclosures are set up together using a specialized rigging hardware and they hang from a single point. These line array speakers are curved backward at the lower portion so that the sound will reach more audience.
