The Classic Series from Furman brings together superior protection and outstanding performance in a sturdy, rack-mountable design. The Classic Series features Furman’s revolutionary Series Multi-Stage Protection (SMP), Linear Filtering Technology (LiFT), and Extreme Voltage Shutdown (EVS). Together, these technologies comprise what is, without question, one of the world's most advanced and comprehensive transient voltage surge supressors.
Furman's exclusive SMP technology provides the highest level of surge & spike protection available.
LiFT offers AC power filtering to ensure clean power for unequaled audio & video clarity.
Advanced EVS circuitry detects dangerous voltage irregularities and safely powers down itself and connected equipment in unsafe conditions.
LED status indicators warn you when voltage is outside of nominal range or when protection has been compromised.
Isolated outlet banks minimize inter-component interference and noise contamination.
Three widely spaced outlets accommodate bulky AC power transformers.
20 Amp rating featuring a high inrush magnetic circuit breaker for added protection.
Nine total outlets (8 rear panel outlets and one front panel convenience outlet).
Rear panel BNC connector powers any standard gooseneck lamp for rear rack illumination.
