Furman PST-8 Furman’s Series Multi-Stage Protection (SMP) delivers the purest AC power and the most comprehensive protection available, going far beyond what is found in traditional surge strips. With Furman’s Power Station Series, everyone can reap the benefits of unrivaled power purification and unequalled surge protection. For over 40 years, Furman has pioneered the development of AC power products for the most demanding audio, video, and broadcast professionals. Today’s overworked, outdated power grid delivers poor quality AC power. When connecting sensitive equipment to regular power outlets, AC noise masks and distorts critical signal information which cripples performance. This is why it’s more important that ever to purify or clean the AC powering your sensitive audio/video equipment.
