Ground loops and unbalanced signals create noise in recording mixers, keyboards, guitars, power amps, live sound, and DJ systems. No one is immune to hum, no matter how good your rig is, so when hum occurs, you need the right tool to quickly and easily get rid of it. The HE-2 Hum Eliminator does away with system noise and ground loops quickly and easily. Extremely high-quality transformers isolate circuits, keeping grounds intact while breaking troublesome loops and balancing unbalanced gear. Since it's totally passive, it injects absolutely no noise into the signal. The 1/4" TRS and XLR in and out jacks make it easy to connect.
