The SPC-20, an AC power conditioning and sequencing system that provides in depth surge protection as well as superior RFI suppression. It can be expanded to power any number of additional circuits all connected via a six wire low voltage line.

The SPC-20 switches the line with solid state devices insuring an extremely long trouble free life, there are no mechanical relay contacts to arc or pit and disrupt the systems operation.

This equipment should be used in all sound and video installations that have a system on/off switch. It performs two extremely important functions, insuring that equipment turn on is accomplished rapidly and in the proper order eliminating any possible damage to high power amplifiers and the associated speakers; and it protects all the equipment from harmful transients and surges.
