The Line Noise BlackHole (LNBH) is a compact, plug-and-play EMI/RFI sink filter designed to passively clean up noisy AC lines. No current limitation, no sonic compression—just quieter backgrounds and more revealing sound.

The Power Noise Problem

Power lines today carry more than voltage—they carry noise. Routers, chargers, appliances, and dimmers inject electromagnetic interference into the AC line. This affects the transparency, dynamics, and clarity of your audio system.

How the BlackHole Works

Unlike series filters that can choke current, the BlackHole connects in parallel to your circuit and absorbs high-frequency EMI/RFI through a 2-stage filtering network with:

  • High differential and common mode attenuation
  • Surge protection (8–15kA)
  • Ultra-low leakage (<0.5mA)

It’s quiet, effective, and doesn't get in the way of your gear.

No Power Restriction, All Gain

Plug the LNBH into any unused wall or power strip outlet on the same circuit as your system. It cleans the entire line—without restricting current flow to your components.

Real-World Results You Can Hear

When installed correctly, it's designed to deliver:

  • Lower background noise
  • Sharper imaging
  • Improved microdetail and texture
  • A more natural, relaxed sound

It doesn’t color the sound. It clears the path.

Technical Specs and Safety

  • Voltage Range: 85–230V AC / 10A
  • Certifications: CE / FCC / RoHS / REACH
  • Construction: IEC inlet + fused switch + NEMA outlet
  • LED Indicator: Green glow confirms power is active

Safe for most HiFi systems, not suitable for medical equipment or high-leakage circuits.

Set It and Forget It

Once plugged in, the Line Noise BlackHole works silently in the background. Add more units across your home for cumulative noise reduction. It's the easiest upgrade you'll ever hear.

The Line Noise BlackHole is designed in the USA and assembled in China using only premium-quality components.
