Pyle B00BARTW42 Silencer Box (2 Channels) with XLR Female Connectors

• 60 Hz Noise removal, removes AC hum. Breaks ground loops safely, guarantees high sound quality.
• Passive device: no power supply needed, high performance, ultra-compact design, 1/4 inch TRS and XLR inputs and outputs on 2 channels.
• Audiophile high-quality components and an extremely rugged construction, automatically converts between unbalanced and balanced signals without signal loss.
• Uses 11: 1 isolating transformer loop antenna and breaks balance audio lines. Automatically translates signal voltages to match the difference in ground potentials.
• Sold as: unit, weight: 500 g.

Almost all 60 Hz mains hum is caused by ground loops that act like radio antennae (loop antenna). The Hum Eliminator eliminates this by breaking the ground loop, making it impossible for the signal lines to pick up the AC hum and noise in the first place. Unbalanced lines are more susceptible to picking up electrical noise and RF inference than balance lines - the longer the unbalanced cable, the greater the chance of a problem. Using this device to connect two piece of equipment is one the the most cost-effective ways to convert between unbalanced signals and truly balanced signals. Automatically translates signal voltages to match the difference in ground potentials.
