The ETC CL-ION is a high-end, large-scale lighting control console designed for the most demanding professional lighting applications in theatre, concert touring, television production, and themed entertainment. As part of ETC's flagship Eos family, it combines powerful processing with an intuitive, workflow-driven user interface. The console is capable of managing vast lighting rigs, supporting up to 6,144 control channels, which allows it to control thousands of parameters across intelligent fixtures, conventional dimmers, and complex media servers. Its processing power enables the creation of intricate cues, effects, and timelines, handling the sophisticated needs of modern automated lighting systems with precision and reliability.

The user interface is built around a multi-touch, high-resolution LCD screen, complemented by physical encoders, playback faders, and hard keys for tactile control. The software, based on the ETC Eos operating system, offers deep programming capabilities including powerful effects engines, pixel mapping for LED arrays, and extensive cue list management with integrated tracking and block cues. The console supports multiple users simultaneously, allowing a programmer, designer, and operator to work on different aspects of the show without interference. It features extensive networking capabilities, with built-in Ethernet ports for connecting to ETCnet or sACN networks, enabling control of distributed dimming racks and other devices across large venues.

Constructed with a robust, touring-grade chassis, the CL-ION is built for reliability in both permanent installations and on the road. It offers flexible configuration options for its control surfaces and can be expanded with additional touchscreens or wings. Redundant power supplies and hot-swappable components are often standard, ensuring maximum uptime during critical performances. As a central component in a professional lighting network, the ETC CL-ION provides lighting designers and programmers with the comprehensive tools, processing muscle, and operational stability required to realize complex creative visions for the world's most prominent stages and productions.
