Just bought two Monster PC1000 clean power strips as Buy.com had them on special for $59. A pretty good deal. Unfortunately as they are marketed for PCs they are marked in a confusing way, at least for me. Of the 8 outlets, 4 are marked "Low Noise Filter Switched" and 4 are marked "Wideband Filter - Unswitched". I know what switched and unswitched is but what is the Wideband and Low Noise difference? Which should I use? Thanks!
