Permanent installation or touring racks are offered for the dx Series dimmers and may easily be installed with the appropriate load or power distribution.  Available in endless configurations, all rack systems are individually tailored for your unique requirements.  The competitions' high priced custom design is our everyday product.  Take a look at exactly how well our racks stand up under the most adverse conditions.

 
"As you promised, it was completely turn-key.  When the electricians hooked up the power, we hooked up the control board, connected the lights, fired everything up and were writing cues and running the show with no glitches.  You guys are doing it right and we certainly appreciate it."  
 


This extremely compact 126 channel installation system is currently working in Honolulu, Hawaii. This system features a unique combination of eighty four channels of 1500 watts dedicated to stage lighting with 24 X 1.5K and 18 X 2.5K assigned as architectural for a grand total of 207 Kilowatts! Other special system features not found from any other manufacturer: a full hot patch field to 240 stage circuits, with the additional 24 X 1.5K and 18 X 2.5K separately wired as house circuits. Two 400 amp three phase mains lugs feeds were provided upon request by the electrical contractor for the venue.

Double wide install rack, 60 X 2.5K

Residing in the Georgia Pacific Television Studios in Atlanta, GA this 60x2.5K dx rack with Electrols' exclusive hot patching to 192 circuits install experiences the absolute worst EM/RFI (electro-magnetic radio frequency interference) environment ever encountered. So bad is it that television monitors must have additional shielding to even work properly. Or even work at all for that matter! The dimming rack, however, performs flawlessly.

36 X 2.5K Installation Rack

Constructed for top feed in and out per client request. Vented, locking front door included to restrict the inquisitive from accessing Electrol's comprehensive standard dimmer functions such as soft patch, dimmer curve, non-dim assignment and output voltage limiting. Lovingly dubbed "The Area 51 Rack" due to its installation at Roswell (GA) Cultural Arts Center. Future sightings will be reported. Maintained by Rubicon Pictures of Atlanta, GA.

This 48 X 3K (220VAC Delta) system has been comfortably toiling aboard the Holland Cruise Lines ship MS Rotterdam for many years now. By far, most cruise ship installations inevitably meet with some difficulties due to wild variations in the quality of on-board ship power. Yet, because of the design efforts of Electrol Engineering and the wonderful on-site personnel of Zsiba Smolover of New Milford, CT, the installation went through without a hitch. Because the dimmer rack was wired directly to the main turbines on the ship, the electrical feed consisted only of three 220 VAC hot legs and a ships'-hull "ground" to power the system. For safety reasons, this dictated the need for double pole circuit breakers on every dimmer channel output as seen in this photo. To make engineering matters even more interesting, the resting place chosen for cabinet was partially exposed to the vagaries of the Atlantic Oceanographic climatic system; hence the pleasingly blue weather-resistant installation rack. Unfortunately, no service calls have been needed.

72 X 1.5K fuzzy touring rack w/ stagepin output

Since taking residence in the Lyric West Theatre Company on the Massachusetts Bay Community College campus, this installation (what can we say, it’s what they wanted...) immediately became the source of much controversy between the union electricians and school officials over what defines "temporary wiring". The school wanted easily to move the rack to their proposed new space, and use the dimmers for their black-box theatre when needed (hence the touring rack request). After only minor bloodshed and an amazing amount of conduit run in the 36 hour period before opening night, an agreement was come to for the theatre workers to strike their cabling after every performance.

36 X 1.5K w/ 6 X 2.5K Touring System

Patchable multi's out, shock mount ATA case (something no other manufacturer can produce in this configuration) constructed for the increased touring schedule for both The Promise Keepers organization and various projects with The Artist (it's an odd combo, we know...) The typical application for this system was required to be: load every channel to the maximum during the heat of the day, bring everything to full and walk away. Only due to Electrol dimmers' extreme capacity for dealing with thermal overloads could this requirement be met. System tortured by Backstage Productions of Minneapolis, MN.

Shockmount ATA Style Trouping Racks

Part #: TRXXATA
(XX= panel space in rack units)

Our ATA cases do more than what is demanded by the Airline Transportation Association in its’ Specification 300, Category 1 standards, which ensure that cases will survive the rigors of 100 round trip shipment by air or common carrier. Our cases are built from low-void ½" high grade plywood, exceeding these standards. We use tough exterior laminates, such as ABS plastic and exclusive aluminum corner and tongue and groove extrusions. The finest heavy duty hardware fastened with steel rivets and washer backed at key stress points makes these cases though to beat.

 Rack Construction


Plywood: ATA series cases begin with select cross laminated, exterior grade plywood. Only the finest hardwoods with a low incidence of knots and voids are chosen. All plywood is sampled and inspected at the dock to ensure it meets our high standards. 3/4" cabinet grade birch is used exclusively as caster board material.

Hardware: All hardware is strictly the finest to suit any application. Positive locking recessed latches and handles are complimented by heavy gauge corner clamps and ball corners for all cases. All hardware is washer backed at key stress points. A wide variety of hardware options such as locks, stacking hardware, casters, valance spanning latches and much more are available.

Laminates: You may select from our standard laminates of ABS plastic in red, white, blue, black, silver, green, orange and yellow. There are a variety of options for an additional charge, including aluminum in mill finish with stucco texture: and Formica and other similar plastic laminates. Our fully automated laminating line features an advanced, moisture-cure urethane adhesive applied as a foam to maximize coverage. This low-solvent process resists reactivation under heat. Humidity is strictly controlled during the adhesive application. The laminated plywood is then placed in a high-pressure press for at least 24 hours. The process results in a bond without peer in the industry.

Extrusions: Our exclusive extrusions feature a specialized alloy which has been field tested for strength and durability. The 6063 alloy is a blend of manganese for strength, copper for heat conduction and silicon for corrosion resistance. The resulting alloy is tempered to T5 hardness, the maximum strength which still permits bending and stapling. Our corner extrusions which accommodate ½" plywood, feature an impressive .090" wall thickness for superior durability. Wide channel tongue and groove valance ensure that case integrity will not be compromised, even in the most abusive environment.
