The 2R series represents the latest evolution of the Brick Wall Surge Filter packaged in an economical two receptacle form. Refinements include better shielding, silent operation, a right angle plug and improved appearance.
This product was initially designed to enhance the protection of any file server by being placed in series between the wall plug and the UPS (UPS’s have limited surge suppression/ filtering abilities). The lack of outlets minimize the chances of accidentally overloading the unit.
The same lack of receptacles makes this 20A unit an excellent choice for the audiophile, as the "cross talk" between digital and analog components becomes a non-issue in a one receptacle configuration. These units are an excellent choice of protection for your complete home theater or audio system.
And of course as a surge suppressor/line filter, both in its endurance and performance capabilities, a Brick Wall Surge Filter still sets the world’s standard. There is no better powerline protection product available today.
This unit is designed to work with 20 amp applications. A 20 amp line and outlet is required for this unit to be used.
