The Absolute Sound Golden Ear Award Winner! The most cost effective noise reduction solution available!
Parallel shunt filter, removes noise with no current limiting. Cumulative effect if used in groups on a circuit. This New & Improved Version 3, has more noise reduction and an LED power indicator!
This little wall-wart squelches AC-borne noise right at the outlet, audibly lowering your system's noise floor. One of the most dramatic and cost-effective audio improvements money can buy
Your equipment is constantly bathed in a "sea" of electrical noise. Most line filters treat only the power coming directly into the equipment. They do nothing about the noise generated by other electronic devices. The Quietline™ Noise Reduction System is a new way to reduce the electrical noise and interference that degrades the sound of your audio system.
The Quietline™ Noise Reduction System is more effective than conventional filters, because it reduces noise at its source. Quietline™ is a very effective shunt filter. It sits across the power line, rather than in series with it, cleaning up noise and interference without affecting the flow of power to your electronics.
There are several sources of electrical noise in nearly every building. The power line itself is inherently noisy and can act as an excellent antenna for atmospheric electrical noise. Defective utility equipment and loose or corroded connections can also create noise.
Radio-frequency interference or RFI (usually radio or TV signals), can have grossly audible effects (such as a buzz from a TV station or hearing CB calls), or more subtle effects (such as veiling, grain and flattening of perspective.)
Electromagnetic interference (EMI) is the "hash" radiated by your computer as well as the pops from your refrigerator's compressor. This noise can enter your electronics through the power line, speaker cables or even along the shield on interconnects.
Even if you already use another noise-suppression system, you'll hear an improvement when you install QuietLine.
It isn't enough to reduce EMI and RFI where they enter. You must suppress the noise at the source. The Quietline™ Noise Reduction System is a set of noise-suppressing modules that treat line noise and interference throughout your home to reduce the noise from computers, digital clocks, power tools and other offending appliances. The Quietline™ Noise Reduction System is a whole-house treatment for noise.
Reduced electrical interference is audible as cleaner sound, improved detail, a wider, deeper soundstage, reduced graininess and less listener fatigue. Even if you already use another power line filter, you will hear an improvement when you install the Quietline™ Noise Reduction System.
The Quietline Mk3 Power Filter is universal and can be used in any country WITH an adaptor. The Quietlines work best though, if used with the proper plug, WITHOUT an adaptor.
- Helps reduce EMI & RFI at or near the source (from TV's, microwave ovens, computers, refrigerators and power tools to name just a few.)
- Works in conjunction with other power filtration sys-tems and surge supressors.
- Operates from the middle of the audio band to several hundred megahertz.

At first, I wasn't sure I heard anything. So, after a few months of use I went around and pulled them all out. That was dramatic. I couldn't put them back in fast enough.
Four QuietLines produced the best noise suppression and most improvement in sound for the lowest cost of any of the PLC products that were tested. The easy-to-use QuietLines are simple effective. Going to eight QuietLine filters is definitely worth the cost. The noise floor seems to be roughly twice as quiet as with four QuietLines with another step up in detail.
This is a must use AC treatment accessory... it works well with other in-line power filters too!
