Looks and works like new. Used once. Would return it but I threw away the packaging. The Furman AC-215A is a compact power conditioner delivering uncompromised AC protection and purification. This unit features Furman's exclusive Series Multi-Stage Protection (SMP) to provide the highest level of surge and spike protection available, while Linear Filtering Technology (LiFT) ensures clean power for unequaled audio and video clarity. The revolutionary Auto-Reset Extreme Voltage Shutdown (EVS) circuitry detects dangerous voltage irregularities, safely powering down connected equipment in unsafe conditions and automatically resetting when voltage returns to a safe level. Its sleek, compact chassis is designed to be easily and discreetly attached to a flat-screen television mount, inside a guitar amplifier, or any remote location where clean, filtered power is needed to protect critical circuits and optimize performance.
