NSI LIGHTING - Light Control Systems
NSI is ushering in a new era of microprocessor controlled stage lighting technology with these products. The powerful NSI digital product series provides advanced, flexible control for a variety of innovative applications. Because of their advanced design, these consoles feature many benefits found in today's personal computers. You can add programmable memory, scene masters and chase effects, all with the simplicity of a familiar two-scene console.
Dimmers and Distro
- Dimmers are devices used to vary the brightness of a light or stage light and are usually controlled remotely by a lighting console or controller by way of a protocol that is usually DMX. A Distro is . Used . a device that distributes power to many devices.. Used . ...Intelligent Lighting
- Intelligent lighting is stage lighting that has automated or mechanical functions beyond traditional, stationary illumination. While intelligent lights can at times display complicated effects and fun. Used . ctions, they are only capable of performing the task set up by the programmer and are therefore sometimes referred to as obedient lighting. Intelligent lights come in many forms, but commonly. Used . are yoked moving heads or scanners and are usually controlled by DMX signals from lighting controllers or consoles. ...Advanced Control Network
- A new protocol designed to improve upon on the exisiting known limitations of the DMX512 protocol. It was developed by the ESTA (The Entertainment Services and Technology Association).
T. Used . he Advanced Control Network (ACN) is intended to provide the next generation standard for the distribution of data in lighting control networks.
ACN needs to do much more than just supe. Used . rcede DMX. Ideally, ACN will unify lighting control networking, allowing a single network to carry many different kinds of lighting-related data and to connect equipment from different manufacturers. ACN is noHertz
- 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.
- Intelligent Fixtures or Moving Lights were originally implemented in 1972, but the first computer-controlled stage lighting fixtures began to gain widespread acceptance in the concert industry in the . Used . early 1980's. As the digital age progressed, the cost of these fixtures was reduced and they slowly started being used in more 'traditional' theatrical environments. Intelligent fixtures are .

Usually relying on compact arc lamps as a light source, these fixtures generally use stepper motors connected to varying internal devices...
Used Dimmer Rack Modules
A dimmer rack module is a small device that is used in professional lighting to adjust the brightness of a light fixture. It works by altering the voltage of electricity that is delivered to the lamp. When the dimmer rack module reduces this power, the brightness of the lamp will fade down (become dimmer). Alternatively, if the dimmer rack module increased the power, the lamp will fade up (become brighter). Interestingly enough, a dimmer rack module allows for minor color control as well.
Although large dimmer racks are sometimes used, these are often replaced with a dimmer rack module, which is smaller and contains a 20 to 50 ampere breaker. The advantage of a dimmer rack module is that it can also supply current to other devices, such as foggers and hazers, or lifting equipment. This is important as these other devices can be damaged if you fail to use a dimmer rack module on non-dimming electrical devices. The circuit to which a dimmer rack module is connected to will be constantly energized, thus protecting these other devices. Even in cases where it is thought that a regular dimmer rack will always be operating at full power, it can be dangerous for non-dimming devices due to interruptions in the data stream caused by DMX signals and noise interference, which would lead to the dimmer dimming the circuit.
