Rockn Stompn RS-4 Musicians Power Strip, Surge Protector, Power Conditioner, Multimode Power Sequencer Designed for quick, safe, easy startup of your rig. RS-4 is a foot activated, 8-Outlet, 15 Amp, UL Listed Surge Protector, Power Conditioner, Four step Multi-Mode Power Sequencer, user adjustable on and off delay from 1 to 15 second, 20 gage fully welded steel enclosure, 15 foot long power cord. The golden rule is to "Always turn your main amp on last, and turn it off first" to avoid the potentially destructive loud "POP." The RS-4 simply does this automatically, powering all your equipment up or down in the proper sequence, every time. Because the RS-4 is microprocessor based, you can independently adjust on and off delay sequence from 1-15 seconds and choose from four sequencer modes of operation. In addition to eliminating that "POP", the RS-4's power sequencer spreads the initial inrush current of your gear over four steps allowing you to power up far more gear, more safely than ever before on a single 15 amp circuit.. Consolidating your gear or your band's gear into a single RS-4 will lower noise and reduce exposure to ground loops. The RS-4 has been tested to and conforms to UL standard 1449 3rd edition and most recently 4th edition for surge protection devices. In addition, RS-4 protects your gear every time you power down. The four relays inside the RS-4, their contacts open up, disconnecting your gear from the power grid. Your gear could not be safer. This feature makes the RS-4 perfect for studio application or anytime you wish to leave your rig in single location ready to go. The RS-4 is manufactured, assembled, handbuilt in Duluth, Georgia U.S.A and Includes lifetime warranty. Thanks for visiting our factory store here on Amazon.
