Morley Gold Series Hum Eliminator

Here's what Morley says about the Hum Eliminator:The Hum Eliminator uses our custom in-house made isolation transformers to break loop antennas that cause ground hum and buzz. Hum Eliminator also converts back and forth between balanced and unbalanced connections and prevents the cable to act as an antenna for noise.Simply place a channel of the Hum Eliminator on the cable connections between the two offending pieces of equipment. Hum Eliminator will not affect the quality of the audio, it will improve it.We use 1/4″ smart jacks that accept any combination of unbalanced (TS) or unbalanced (TRS) plugs. These are passive devices (no power required), in cold rolled steel housings, hand-soldered circuit boards and top quality components and hardware.Specifications2-Channel Hum Eliminator1/4″ Smart Jacks and XLR JacksDimensions: 4.75″ (L) / 3.25″ (W) / 1.75″ (H)Prevents Ground Loops That Create Hum and BuzzCustom Morley Isolation TransformersConverts Back and Forth Between Unbalanced and Balanced Cable TypesSimply Insert on Audio Connections Between Offending Pieces of GearNot Intended for Use on Mic Level, Instrument or Powered Speaker Line
