Electronic Theater Controls Dimmer Rack Modules

Since its founding by Fred Foster in 1975, ETC (Electronic Theatre Controls, Inc.) has become a global leader in award-winning entertainment and architectural lighting equipment. ETC's fixtures, lighting control consoles, dimmers and distribution products are the backbone of lighting systems in venues worldwide - from schools and churches, to community theaters and TV studios, to opera houses and theme parks. Over the first decade of its history, ETC earned a reputation for sophisticated microprocessor-based lighting control consoles. By 1990, ETC had acquired Lighting Methods, Inc., a Rochester, New York-based manufacturer of entertainment dimming systems. ETC quickly became one of the largest fully-integrated entertainment lighting control manufacturers in North America, with offices in Middleton, WI; Orlando, FL; Rochester, NY; and Hollywood, CA. The next phase of growth began in 1995, when ETC acquired the lighting control division of London-based distributor ARRI GB. That same year, ETC opened an office in Hong Kong, extending its expansion into Asia. In 1997, ETC opened an office in Copenhagen, Denmark, to serve the Northern European market, and a year later opened an office in Rome, allowing greater access to Southern Europe. ETC acquired Transtechnik Lichtsysteme, Holzkirchen, Germany in 2002, widening ETC's market potential in Europe. Continuing its growth, ETC took an equity position in Avab France in 2003. In 2004, ETC acquired Dutch sine wave dimming manufacturer IES and its industrial weighing and measuring division Penko Engineering BV, both located in Veenendaal, the Netherlands. Beginning March 31, 2005, all formerly separate operations of ETC in Europe joined under the common corporate banner of ETC. ETC's new international headquarters, located in Middleton, WI (near the state capital Madison) serve as hub of global administration and manufacturing. Through the years, ETC has gained an industry-wide reputation for outstanding service and customer support. ETC not only maintains in-house, 24-hour Technical and Customer Service staffs, but an extensive network of factory-trained, authorized field service centers.

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.
