- 0-10V
0-10v is a is a type of Lighting Control that requires a 230v power cable aswell as a 2 core analogue signal cable per every circuit.
The benefit of 0-10v is that the driver is matched to the LED Bulb and as such the 2 work in harmony for perfect dimming over LEDs, the this system worksis that if you require 65% output from the Circuit then the Dimming system provides 230v power and 6.5v DC, if you require 20% output then the system outputs 230v and 2v DC.
or
is one of the earliest and simplest electronic lighting control signaling systems; simply put, the control signal is a DC voltage that varies between zero and ten volts. The controlled lighting should scale its output so that at 10 V, the controlled light should be at 100% of its potential output, and at 0 V it should at 0% output (i.e., off). Dimming devices may be designed to respond in various patterns to the intermediate voltages, giving output curves that are linear for: voltage output, actual light output, power output, or perceived light output.
Dimming fluorescent ballasts and dimming LED drivers often use 0–10 V control signals to control dimming functions. In many cases, the dimming range of the power supply or ballast is limited. If the light output can only be dimmed from 100% down to 10%, there must be a switch or relay available to kill power to the system and turn the light completely off.
Most 0–10 V controllers offer either a built-in line voltage relay or an external line voltage relay. Depending on the application, these options should be considered.
- 1080P
Any display device that advertises 1080p typically refers to the ability to accept 1080p signals in native resolution format, which means there are a true 1920 pixels in width and 1080 pixels in height, and the display is not over-scanning, under-scanning, or reinterpreting the signal to a lower resolution. The HD ready 1080p logo program, by DIGITALEUROPE, requires that certified Display Devices support 1080p 24 fps, 1080p 50 fps, and 1080p 60 fps formats, among other requirements, with fps meaning frames per second.
Pixels per screen size per technology
- DVD Quality (480P) = 307,200 Pixels
- HD Ready (720P) = 921,600 Pixels
- Full HD (1080P) = 2,073,600 Pixels
- UHD (4K, 2160P) = 8,294,400 Pixels
- 16:9
- is an aspect ratio with a width of 16 units and height of 9. Since 2009 it has become the most common aspect ratio for televisions and computer monitors, and is also the international standard format of HDTV, Full HD, non-HD digital television and analog widescreen television.
- 2.35:1
- Anamorphic format is the cinematography technique of shooting a widescreen picture on standard 35 mm film or other visual recording media with a non-widescreen native aspect ratio. It also refers to the projection format in which a distorted image is "stretched" by an anamorphic projection lens to recreate the original aspect ratio on the viewing screen. (It should not be confused with anamorphic widescreen, a different video encoding concept that uses similar principles but different means.) The word "anamorphic" and its derivatives stem from the Greek words meaning formed again. As a camera format, anamorphic format is losing popularity in comparison to "flat" (or "spherical") formats such as Super 35 mm film shot using spherical lenses; however, because most movie projectors use anamorphic projection format, spherical format negatives are commonly converted into anamorphic prints for projection.
- 2K Driver Array
2K Driver Array
The two high frequency drive units are housed in a single rigid chassis.
By minimising the distance between drive units, a single-point sound source is created, which together with the acoustic ‘scoop’, produces exceptionally wide dispersion for precise and consistent high frequency performance throughout the room.
- 3K Driver Array
3K Driver Array
Three drive units — mid, tweeter and super-tweeter — are housed in a single rigid, die-cast chassis.
By minimising the distance between drive units, a single-point sound source is created, which together with the acoustic ‘skoop’, produces exceptionally wide dispersion for precise and consistent high frequency performance throughout the room.
- Aktiv Servo Bass System
Aktiv Servo Bass System
Producing an accurate and musical performance from the powerful bass section of the loudspeaker requires precision and control.
Linn’s Aktiv Servo-Driven Bass system constantly measures the precise motion of each unit compared to the original input signal, and immediately corrects it to ensure that the output perfectly matches the input. The result is deep and powerful bass that is always musical.
- Anamorphic
- Anamorphic format is the cinematography technique of shooting a widescreen picture on standard 35 mm film or other visual recording media with a non-widescreen native aspect ratio. It also refers to the projection format in which a distorted image is "stretched" by an anamorphic projection lens to recreate the original aspect ratio on the viewing screen. (It should not be confused with anamorphic widescreen, a different video encoding concept that uses similar principles but different means.) The word "anamorphic" and its derivatives stem from the Greek words meaning formed again.

- Aspect_Ratio
The aspect ratio of an image describes the proportional relationship between its width and its height. It is commonly expressed as two numbers separated by a colon, as in 16:9. For an x:y aspect ratio, no matter how big or small the image is, if the width is divided into x units of equal length and the height is measured using this same length unit, the height will be measured to be y units.
In, for example, a group of images that all have an aspect ratio of 16:9, one image might be 16 inches wide and 9 inches high, another 16 centimeters wide and 9 centimeters high, and a third might be 8 yards wide and 4.5 yards high.
- AV Receiver
- An audio/video receiver (AVR) is a consumer electronics component used in a home theater. Its primary purpose is to receive audio and video signals from a number of sources, processing them to drive loudspeakers and a display. Possible displays include television, monitor, or video projector while the inputs may come from television, satellite receiver, radio, DVD players, Blu-ray Disc players, VCRs, and video game consoles.
The AVR source selection, and settings such as volume, are typically set by a remote controller.
- Blu-ray
- Blu-ray or Blu-ray Disc (BD) is a digital optical disc data storage format. It was designed to supersede the DVD format, in that it is capable of storing high-definition (720p and 1080p) and ultra high-definition video resolution (2160p). The plastic disc is 120 mm in diameter and 1.2 mm thick, the same size as DVDs and CDs.[5] Conventional (pre-BD-XL) Blu-ray Disc discs contain 25 GB per layer, with dual layer discs (50 GB) being the industry standard for feature-length video discs. Triple-layer discs (100 GB) and quadruple layers (128 GB) are available for BD-XL re-writer drives.[6] The name "Blu-ray" refers to the blue laser (specifically, a violet laser) used to read the disc, which allows information to be stored at a greater density than is possible with the longer-wavelength red laser used for DVDs. The main application of Blu-ray is as a medium for video material such as feature films and physical distribution of video games for the PlayStation 3, PlayStation 4, and Xbox One. Besides the hardware specifications, Blu-ray is associated with a set of multimedia formats.
- Cable_Certification
Certification instruments are the only tools that provide "Pass” or "Fail” information in accordance with industry standards. In North America, the prevalent industry standards organization dealing with the transmission capabilities of structured cabling is the Telecommunications Industry Association (TIA). In international markets, the Electro-technical commission of the International Organization for Standards (ISO/IEC) creates and maintains standards for telecommunication cabling.
Certification test tools determine whether a link is compliant with a category (TIA) or class (ISO); for example, category 6 or class E. These standards are independent of specific network technologies. This makes them more "future proof” because new network technologies can emerge that base their designs on these standards and would therefore be supported by the certified installed cabling. Certification is the final step required by many structured cabling manufacturers to grant their warranties for a new cabling installation.
- Cable_Qualification
- Qualification testers meet the needs of network technicians who do not install new cabling, but need to troubleshoot operating networks. Qualification testers perform tests that decide whether an existing cabling link will support the requirements for "Fast Ethernet” (100BASE-TX), Voice over Internet Protocol (VoIP), or Gigabit Ethernet. These test tools furthermore allow the network technician to quickly isolate cabling problems from network protocol or addressing problems. Qualification test tools include all the capabilities of verification test tools but they are more powerful in that they perform an assessment of the cabling bandwidth and identify defects that affect the bandwidth. Qualification testers do not execute the battery of tests prescribed by the standards to be considered a "certification tool.”
- Cable_Verification
- Verification test tools perform basic continuity functions, they assure that all wires in a cabling link are connected to the proper termination points and not to any other conductors. In twisted pair cabling, it is critical to maintain the proper pairing of the wires. Better verification test tools also verify wire pairing and detect installation defects like "split pairs”. Verification test tools may also assist in troubleshooting by providing a toner to locate a cabling link. Verification tools sometimes include additional features such as a Time Domain Reflectometer (TDR) to determine length of a cable or distance to a break or short circuit. These test tools do not provide any information on bandwidth or suitability for high-speed data communication.

- C-CAM
Ceramic-Coated Aluminium/Magnesium is a material originally developed by the aerospace industry for jet engine components. Its properties are ideal for loudspeaker cones being extremely rigid, yet light enough to yield high overall efficiency. In manufacture, aluminium/magnesium alloy undergoes a three-stage stress-relieving process to remove surface deformation and molecular weakness. Once formed, the alloy cone is subjected to a high temperature anodic coating process in which a layer of pure ceramic alumina is depleted onto its surfaces to a depth of 50 microns, producing a completely rigid sandwich of alloy and heat-dissipating ceramic material.
Conventional cones are liable to flex or twist in operation, producing a significant level of audible distortion. C-CAM cones have a much higher resistance to bending stress and therefore exhibit much greater fidelity over their entire operating range. C-CAM tweeters and woofers share an audible consistency producing a smooth transition of frequencies and a sense of realism and cohesion in the soundstage.
- CD-ROM
- A CD-ROM /ˌsiːˌdiːˈrɒm/ is a pre-pressed optical compact disc which contains data. The name is an acronym which stands for "Compact Disc Read-Only Memory". Computers can read CD-ROMs, but cannot write to CD-ROMs which are not writable or erasable.
- Chakra Amplification
Linn's patented Chakra amplifier technology combines the speed and precision of monolithic chip technology with the robustness and smoothness of bi-polar transistors.
It adapts to the constantly varying demands of the music by using a monolithic at low currents and bi-polar transistors as 'boosters' at higher levels. Chakra uses a unique approach to transition between these technologies, guaranteeing precisely-controlled clean, silent power at all listening levels.
- Custom-Designed Drive Units
Custom-Designed Drive Units
The ambitious design of Series 5 led to a unique set of requirements for the drive units that couldn’t be met by any existing specification.
The 530 needed compact yet very long-throw, low-resonance units for use in the Isobarik bass system. The unique arrangement of tweeter and bass/mid driver on both models also required customised drive units. The bass/mid driver uses a unique doped, dual-layer, sliced cone design and an anti-resonant chamber on the back of the high quality tweeter improves high frequency performance when used in conjunction with the familiar Linn ‘skoop’, producing outstanding dispersion characteristics.
- Dali
Dali (Digital Addressable Lighting Interface) is a type of Lighting Control used mostly in commerical projects, however DALI is also becoming popular amongst developers of MDU projects, with DALI each Light is individually identified and can be added to a group of lights to form a circuit, this configuration can be changed whenever needed.
DALI requires 230V Permanent live circuit to power the Balasts along with a 2 core signal cable (>1mm2) this signal cable can be wired in any configuration to a maximum of 64 Balasts, each Balast is individually identified on the system and can be grouped with other Balasts on the same signal cable to a maximum of 16 groups.
DALI is an International Standard (IEC 62386) for the control of electronic ballasts, transformers, LED's, emergency lights and exit signs in an easy to manage digital lighting control system.
- Digital media
- Digital media is any media that is encoded in a machine-readable format. Digital media can be created, viewed, distributed, modified and preserved on digital electronics devices. Computer programs and software; digital imagery, digital video; video games; web pages and websites, including social media; data and databases; digital audio, such as mp3s; and e-books are examples of digital media. Digital media are frequently contrasted with print media, such as printed books, newspapers and magazines, and other traditional or analog media, such as pictures, film or audio tape.
- DILA
D-ILA, or Direct-Drive Image Light Amplification, is JVC-developed technology that delivers unmatched performance, with natural color reproduction, an image so smooth that it rivals film, and contrast that does justice to the most demanding program material. Since our first D-ILA projector was launched in 1997, the technology has been employed where nothing but the cleanest, sharpest, most accurate image would suffice. Today, some of the industry’s most sophisticated projectors from the most respected manufacturers use D-ILA technology licensed from JVC.
D-ILA is liquid crystal technology, but it’s very different from the liquid crystal display (LCD) technology found in many products today. D-ILA is what’s called liquid crystal on silicon, or LCOS, but JVC made several improvements to basic LCOS technology to develop D-ILA. At its heart is the D-ILA device, or chip, designed and manufactured by JVC. Every JVC D-ILA projector uses three D-ILA devices, one each for red, green and blue – the three colors that are combined to create the full color palette.
- DLP
Digital Light Processing (DLP) is a display device based on optical micro-electro-mechanical technology that uses a digital micromirror device. It was originally developed in 1987 by Larry Hornbeck of Texas Instruments. While the DLP imaging device was invented by Texas Instruments, the first DLP-based projector was introduced by Digital Projection Ltd in 1997. Digital Projection and Texas Instruments were both awarded Emmy Awards in 1998 for the DLP projector technology. DLP is used in a variety of display applications from traditional static displays to interactive displays and also non-traditional embedded applications including medical, security, and industrial uses.
Most people prefer DLP as the type of projection system as it produces true cinematic colours and as such creates a true cinematic experience.

A depth of bass normally associated with much larger speakers.
By using two bass drive units working in tandem, positioned face-to-face at the foot of the speaker, bass is directed downwards and radiates out from the speaker through a precisely engineered air gap above the solid machined base.
- Leading_edge
Leading-edge dimmer switches are cheaper and simpler than trailing-edge, and were used originally to dim incandescent and halogen bulbs or wirewound magnetic transformers. They use a ‘TRIAC’ (Triode for Alternating Current) switch to control power, and are sometimes called TRIAC dimmers.
Many existing leading-edge dimmer switches have a relatively high minimum load, which often rules out their use with modest LED or CFL lighting circuits. However, leading-edge dimmers are by far the most common dimming control in existence.

- Metal Matrix Polymer driver cones have a polypropylene base loaded with metallic particles to offer a rigid and responsive structure. They are manufactured using a sophisticated high-pressure injection process, which modulates cone thickness at critical points to optimise stiffness and consistency, resulting in a superior sonic performance.
- NFC
- Near-field communication (NFC) is a set of communication protocols that enable two electronic devices, one of which is usually a portable device such as a smartphone, to establish communication by bringing them within about 4 cm (2 in) of each other.
- Optical disc
- In computing and optical disc recording technologies, an optical disc (OD) is a flat, usually circular disc which encodes binary data (bits) in the form of pits (binary value of 0 or off, due to lack of reflection when read) and lands (binary value of 1 or on, due to a reflection when read) on a special material (often aluminium[1] ) on one of its flat surfaces. The encoding material sits atop a thicker substrate (usually polycarbonate) which makes up the bulk of the disc and forms a dust defocusing layer. The encoding pattern follows a continuous, spiral path covering the entire disc surface and extending from the innermost track to the outermost track. The data is stored on the disc with a laser or stamping machine, and can be accessed when the data path is illuminated with a laser diode in an optical disc drive which spins the disc at speeds of about 200 to 4,000 RPM or more, depending on the drive type, disc format, and the distance of the read head from the center of the disc (inner tracks are read at a higher disc speed). Most optical discs exhibit a characteristic iridescence as a result of the diffraction grating formed by its grooves. This side of the disc contains the actual data and is typically coated with a transparent material, usually lacquer. The reverse side of an optical disc usually has a printed label, sometimes made of paper but often printed or stamped onto the disc itself. Unlike the 3½-inch floppy disk, most optical discs do not have an integrated protective casing and are therefore susceptible to data transfer problems due to scratches, fingerprints, and other environmental problems.
- Powered By Dynamik
Linn pioneered the use of Switch Mode Power Supplies for high-end audio, developing our own audio-optimised power supply technology to generate stable, low noise power rails for the audio circuitry in a compact, cool-running package.

The complex laminated cabinet construction is pressure-formed to produce the distinctive curved design while providing an exceptionally rigid shell for the drive units to operate with minimised resonance. Carefully placed internal bracing provides added rigidity and an acoustically inert enclosure for stable mounting of the drive units.
- Projectors
A projector or image projector is an optical device that projects an image (or moving images) onto a surface, commonly a projection screen. Most projectors create an image by shining a light through a small transparent lens, but some newer types of projectors can project the image directly, by using lasers. A virtual retinal display, or retinal projector, is a projector that projects an image directly on the retina instead of using an external projection screen.
The most common type of projector used today is called a video projector. Video projectors are digital replacements for earlier types of projectors such as slide projectors and overhead projectors. These earlier types of projectors were mostly replaced with digital video projectors throughout the 1990s and early 2000s (decade), but old analog projectors are still used at some places. The newest types of projectors are handheld projectors that use lasers or LEDs to project images. Their projections are hard to see if there is too much ambient light.
Movie theaters used a type of projector called a movie projector, nowadays mostly replaced with digital cinema video projectors.

- Computer software, or simply software, is that part of a computer system that consists of encoded information or computer instructions, in contrast to the physical hardware from which the system is built.
- THX
The THX Story
Born out of the Star Wars legacy and tied to one of the world's most acclaimed filmmakers, no other brand resonates with consumers as deeply, and with greater trust than THX.
One week after "Star Wars Episode V: The Empire Strikes Back" debuted in theatres, George Lucas hired audio scientist, Tomlinson Holman, to design the audio mixing facilities at Lucas' Skywalker Ranch in Northern California. To begin the project, Lucas gave Holman one year to examine film audio throughout the entire production chain - from the set to the theatre, and everything in between. Holman's goal was to find a way to improve cinematic sound production and create specifications to design the state-of-the-art audio mixing rooms that would eventually house Skywalker Sound.
During that year, Holman was shocked to discover the state of most commercial cinemas. While Dolby Laboratories had made significant contributions to how sound was recorded and played back on film, no one had control over what happened on the production set or in the theatre itself. Holman found that most commercial theatres had not seen significant technology improvements since World War II. Viewing angles were poor, inadequate light levels distorted images, and the quality of sound systems and auditorium acoustics made it impossible to hear the dialogue, let alone experience the filmmaker's vision.
Bringing the THX Experience to Moviegoers
After the Skywalker Sound audio facilities and Stag Theatre were completed, Lucasfilm began receiving requests from visiting commercial theatre owners and Hollywood studio executives to incorporate the Ranch's performance standards into their cinema auditoriums and aging mixing rooms. Realizing that this could change the way moviegoers experienced feature films, Lucas and the soon-to-be THX team designed a certification program to go beyond the walls of Skywalker Ranch. Thus, THX was born, and made available to movie audiences to coincide with the release of Lucas' next film, "Star Wars Episode VI: Return of the Jedi" in 1983.
The Process of THX Product Certification
The THX testing process usually begins early in product development. Manufacturers ship samples to the THX Testing Lab in Northern California where a team of expert technicians carefully analyzes each sample and produces reports on their findings. Big reports! They cover hundreds of data points and virtually every aspect of the product's operational performance.
These findings are then sent to the manufacturer with suggestions for fixing any problems that could prevent certification. In many cases, THX requires the manufacturer to adjust the product's design or firmware and integrate THX playback features to improve performance and meet the THX spec. Further testing, modifications, tweaks and upgrades are done, and the manufacturer sends back the product for final evaluation.
With all of this testing from THX, the consumer is assured that the speaker system they are purchasing meets the highest standards for quality and compatibility right out of the box.
THX Audio Certification Categories
THX has multiple certification categories based on the room size in which the equipment will be installed. This ensures a THX home theatre system will play loud & clear without audible distortion at THX reference levels in specific room sizes and at specific viewing distances from the screen. This also certifies that the subwoofers will properly pressurize the theatre, so that even the most demanding of movie sound effects are heard and felt with visceral clarity. Of all the THX certification standards Ultra2 is the most demanding as Ultra2 systems are designed for room larger than 85 cubic meters (3000 cubic feet) with viewing distances from the screen greater than 4 meters (12 Feet).

- Trailing_Edge
Trailing-edge dimmers are more sophisticated than leading-edge dimmers, and usually use a MOSFET (Metal Oxide Semiconductor Field Effect Transistor) or IGBT (Insulated Gate Bipolar Transistor) switch rather than a TRIAC and coil. This benefits the user with smooth, silent dimming control, absent of any buzzing noise.
A trailing-edge dimmer has a lower minimum load (often 10W) than leading-edge dimmers, making it a better choice for dimming modestly sized low-powered lighting circuits.
Particularly beneficial for incandescent and halogen bulbs is the ‘soft start’ feature in trailing-edge dimmers, which prevents filament bulbs from dying or exploding of thermal shock when first switched on.
- U/UTP
Unshielded Overall & Unshielded Twisted Pair - The U/UTP cable
consists of pairs of wires twisted together. This is
one of the most basic methods used to help prevent
electromagnetic interference.
Adding a shield to your cable can reduce the negative effect caused
by EMF electromagnetic interference in the correct environment.
If using any form of shield you should ensure that both ends are Ports
are Shielded otherwise using a shielded cable on Unshielded ports can
cause the shield to act as an amplifier and do the opposite of what a shielded

- VPN/SSL
A VPN enables you to link two remote offices, branch offices back to HQ or home-based/mobile teleworkers back to your office. Once connected, they have access to your office/remote resources through a secure encrypted tunnel allowing remote desktop, file sharing and seamless access to other resources and devices.
The Vigor 2860 allows you to set up up to 32 simultaneous VPN tunnels to remote offices or teleworkers. The Vigor 2860 supports all industry standard protocols, including encryption and authentication methods. Teleworkers can authenticate directly with your LDAP server if preferred.
The Vigor 2860 supports VPN trunking; this allows you to create tunnels down muliple WAN connections to a remote site in order to increase bandwidth. VPN trunking also provides failover (backup) of your VPN route down a secondary WAN connection. You can learn more about DrayTek VPN here.
The Vigor 2860 also supports SSL VPN. These are encrypted tunnels linking your teleworker back to your main office but they are 'clientless in that your O/S does not need to generate the tunnel and you do not need to install any VPN software manually. You instigate an SSL tunnel from your regular web browser, so it could be in a web cafe or guest network, and the tunnel is creating using SSL technology - the same encryption that you use for secure web sites such as your bank. The Vigor 2860 can operate SSL VPNs in either Proxy or full tunnel mode and allows up to 16 simultaneous incoming users. For SSL VPN tunnel mode Windows OS, Mac OS X, Apple iOS and Android are supported.
