Subs - A sub or subwoofer is a speaker dedicated to the reproduction of bass frequencies, usually from about 20 Hz to about 200 Hz. . Used . . Used . ...

Auxiliary Output - A seperate line level output from a sound console that is to be used for foldback or monitoring that does not use up another main output. Each in channel has a path to the Auxiliary bus. It is also . Used . useful to send a signal to a separate effects processor.

Acoustics - Acoustics is a branch of physics and is the study of sound, mechanical waves in gases, liquids, and solids. A scientist who works in the field of acoustics is an acoustician. The application of acoust. Used . ics in technology is called acoustical engineering. There is often much overlap and interaction between the interests of acousticians and acoustical engineers.

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 .

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.

Delay - Delay is an audio effect which records a signal or sound and then plays it back after a period of time. The delayed signal may be played back multiple times or looped back into the recording again to . Used . create the sound of a repeating decaying echo. Unlike reverb, which uses reflected sound to produce many echos, delay has greater control over the number of times the sound is echoed. . 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.
