Audioquest Jitterbug FMJ USB Data & Power Noise Filter
- Dual Discrete Noise-Dissipation Circuits - Reduces the noise and ringing that plague both the data and power lines of USB ports. Reduces jitter, unwanted noise currents, and parasitic resonances. Packet errors are sometimes eliminated completely. Improves dynamic contrast, warmth, and resolution.
- Full Metal Jacket (FMJ) Shields Against External Noise
- Integrated Noise-Stopper Cap Further Reduces Noise
Many tens of thousands of music lovers are already enjoying better audio enabled by the AudioQuest JitterBug USB Noise Filter—whether plugged into a car’s USB jack, or a laptop computer, or a USB “service-only” jack on an Ethernet Streamer, etc…
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 device—JitterBug 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 JitterBug’s output is crucial to JitterBug’s 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 port—in parallel to the first—except with JitterBug FMJ’s front door closed.
