Perfect for musicians and audio professionals, the Rolls HE18 is a two-channel audio hum and buzz remover that virtually eliminates 60 Hz hum from a balanced or unbalanced line. The unit also converts unbalanced signals into balanced signals and vice versa, improving the overall noise performance of your audio system. Easy and convenient to use, the HE18 is completely passive and doesn't require power to operate.
