AudioQuest JitterBug FMJ USB 2.0 Power & Noise-Filter

AudioQuest JitterBug FMJ (Full Metal Jacket) USB 2.0 Noise Filter uses Dual Discrete Noise-Dissipation Circuits to reduce the radio-frequency noise and resonances that are inherent to all digital electronics. The result is more spacious and compelling sound music dialog etc. for a better audio experience.

JitterBug FMJ features a shielded metal case to protect against external noise. An included USB plug is perfect for when JitterBug FMJs USB output port is unoccupied or when using a second JitterBug in parallel to the first further preventing high-frequency noise from contaminating the audio signal.

Many tens of thousands of music lovers are already enjoying better audio enabled by the original AudioQuest JitterBug USB Noise Filterplugged into cars USB jacks laptop computers USB service-only jacks on Ethernet Streamers and more.

Now JitterBug FMJ with its Full Metal Jacket raises the stakes. Whether used in series (in-line) or in parallel JitterBug significantly reduces contamination from RF generated by a computer car or other devicesJitterBug FMJ also thoroughly addresses environmental RF Noise taking advantage of this vulnerable interface.

The new metal case is the most obvious change though even the seemingly innocuous hinged rubber piece covering JitterBugs output is crucial to JitterBugs improved performance. That little black door is RF-proof thanks to the material being substantially RF-absorbing Carbon.

Employ one JitterBug in series between any computer smartphone NAS streamer or car audio system and a USB input. For an additional sonic improvement use a second JitterBug in another unoccupied USB portin parallel to the firstexcept with JitterBug FMJs front door closed. A JitterBug in series with AudioQuest DragonFlys Black or Red always helps those wonderful creatures fly higher and faster. However its best to experiment when putting a JitterBug in front of a DragonFly Cobaltwhich itself employs some of JitterBugs filtering and so the two filters in series can help or hurt performance depending on specific equipment and context.

Noise reduction and noise dissipation is AudioQuest! One cant hear our modern worlds pervasive RF Noise itself but the compromises it causes robs us of detail and contrast and outright buries so much subtlety. Fight back with JitterBug FMJ.
