Entertainment Technology, manufacturer of IGBT-based distributed dimming products for theatres, schools/universities, hospitality, houses of worship, and other applications, offers a range of products that can be distributed throughout a space: The Bak Pak individual dimmer and the Intelligent Raceway system. Bak Pak is a compact, lightweight dimmer that attaches to conventional lighting fixtures, providing powerful, quiet dimming capability wherever a need exists for a “single” dimmer, thus eliminating the need for additional dimming rack space. The Intelligent Raceway also installs adjacent to the lights it controls, eliminating the need for a separate equipment room to house noisy, heat-generating dimmer racks. It serves as one power and control network that supplies both fixed and automated lighting loads, eliminating duplication. End users avoid extensive load wiring and installation costs that racks or other dimming systems require.

ETC offers a full range of dimming products for entertainment and architectural venues worldwide. The Sensor+® and Unison™ dimming systems and the SmartPack® product line use standard phase-control technology for efficient dimming installations. The technique of varying the switch-on point of the lamp current is established in tradition and is cost effective. SmartPack (pack, wall-mount, or touring rack) is a super-compact dimming solution when dimming modularity is not required, but density and economy are critical. For distributing dimmers throughout a venue, the SmartBar™, with extra operational features, is appropriate. In addition, the new Sensor+ and IES SineWave™ technology controls the amplitude of the sine wave, offering complete silence at the lamp as well as lower power costs. Quiet attributes combined with Ethernet data and status feedback make SineWave well suited to many dimming situations.

Focus Brain is a wireless controller featuring a UHF wireless remote control unit with DMX output to be used for controlling lighting fixtures and/or intelligent lighting while focusing them. One person can control all dimmer channels. The handheld unit uses a small number of easy-to-operate keys for “dialing in” the numbers of the dimmer channels, levels, etc. These commands are sent via a radiolink to the rackmount receiver unit that translates them into the proper DMX commands. A DMX input allows merging from scenes from the main desk, and 50 full scenes can be stored in the remote control. Special custom software permits direct control of many consoles on the market through the RS232 ports directly in the remote port of the desk.
