Making your selection The Ultra Series Power Wedge® 1118 Power Pack Power Conditioners Power Link Power Cords FAQ Get Our Catalog		The standard Power Wedge Ultra and Power Pack filters are series filters which place the filter into the electrical path. In addition, the Ultra Power Enhancer 2 contains additional parallel filtering and damping. As long as it is on the same electric circuit, the Ultra Power Enhancer 2 will benefit any component plugged directly into it, as well as any components plugged into the same circuit.. The Ultra Power Enhancer circuitry was originally conceived as an add on filter for people facing extreme levels of EMI and RFI that the standard Ultra Power Wedge filter could not handle. While it certainly shines in that application, we have found it to be helpful to other people as well. The typical reaction is to describe the background as blacker. This a result of a further reduction of the noise on the power line which pushes the system noise floor down. The Ultra Power Enhancer circuitry is also designed to further cushion the effect an amplifier has on other components by providing additional damping. Systems that feature very large, current hungry amplifiers will gain additional improvements from the Ultra Power Enhancer 2.
