With a 2100 Joule rating and 8 outlets, the WB-200-8PS offers serious surge protection and noise filtration for smaller systems. Install it on the wall, in a cabinet, or simply place it on the floor behind a credenza. Mounting to a wall or cabinet is fast and easy thanks to built-in keyholes and an included template. We've been there before - you get all the power cords just where you want them, only to forget about the "wall wart" for the IR block or the network switch. Then you have to undo something just to make it all fit and then the bulky "wart" covers up the outlet next to it! To solve this, we have provided ample space between some of the outlets so every one can be used. Sensitive A/V equipment is negatively impacted by noisy appliances and other electronics that create interference on the AC line. All WattBox power conditioners feature noise filtration that cleans up this "dirty power" to deliver the purest A/V experience possible. By lowering the audio noise floor and reducing hum, you hear exactly what was intended. Video performance can see an improvement too - with reduced power-related artifacts on HD displays. Surges can come from a variety of sources - from fluctuations at the power company to catastrophic events such as lighting. This excess energy can damage your connected equipment if not properly protected. The Joule rating is a measure of a surge protector's ability to "clamp" this excess energy down to a safe level - the higher the rating, the more protection your equipment has. Not only can surges creep in on the power, but also telephone, coax and network cables. Jacks for RJ11 or RJ45 connections are provided with full protection on all 8 pins for telephone and Ethernet applications. Today's sophisticated HD cable and satellite systems have higher bandwidth requirements than they did even a few years ago. Dual 3 GHz coax connections not only protect you against surge, but they deliver premium signal quality with less than 1 dB of attenuation. Pass-through voltage is supported for satellite systems.
