Hey, guitarists, bassists, and keyboard players: your AC power is contaminated! No matter where you play, unreliable power makes amps sound muddy, guitars lose their bite, basses lose punch, and keyboards lose clarity. You need Furman's PS-PRO II! It lowers AC line impedance while storing energy for peak current demands. Plus, it dramatically lowers line noise in the audio frequency band. With Furman's Series Mode PROtection, damaging transient voltages are safely absorbed, clamped and dissipated. No sacrificed parts, no service calls, no down time. To further protect your precious gear from spikes, the 20-amp, 8-outlet PS-PRO powers up a rackful of equipment in a 3-step delayed sequence.
