Designed for commercial A/V installers, the CN-1800S combines robust control capabilities via SmartSequencing technology, advanced AC protection, and AC noise filtration. The CN-1800S allows large and complex A/V systems to be safely powered on and off with a simple press of a button or turn of a key, even by nontechnical personnel. SmartSequencing's bidirectional communications between installed units enables a primary unit to control and sequence multiple secondary units, ensuring multizone electronic systems are powered on and off safely and dependably from a single control point across an entire installation.
