The Furman CN-1800S is a commercial-grade 15A power sequencer and surge protector designed for A/V installations. Featuring SmartSequencing™ technology, it safely powers on/off large systems with a single push of a button or turn of a key. The CN-1800S provides Extreme Voltage Shutdown (EVS) protection, Series Multi-Stage Protection (SMP) for superior surge defense, and Linear Filtration Technology (LiFT) for clear audio/video performance. With RS-232 control, optional BlueBOLT® compatibility, nine total outlets, and diagnostic lights, the CN-1800S ensures reliable, remote-managed, and clean power for complex commercial A/V systems.
