Eight-Outlet Audio Surge Protector

The 8R family of products represents another evolution of the Brick Wall Surge Filter. Refinements include better shielding, silent operation, a right angle plug and improved appearance. The product also now comes with two additional "fixed" (always on) outlets for use with amplifiers, DVRs, tuners etc.

For the audiophile and/or home theater enthusiast, we have included receptacles isolated by duplex to help prevent the "cross talk" between digital and analog components.

This is an excellent unit for protection your home theater or audio system; from your HDTV to your DVR to your amplifier.

And of course as a surge suppressor/line filter, both in its endurance and performance capabilities, Brick Wall Surge Filter still sets the world's standard. There is no better powerline protection product available today.
