USB Data & Power Noise Filter: The Audioquest JitterBug is designed to
remove unwanted noise currents and parasitic resonances from both the data
(communication) and Vbus (power) lines of USB ports. JitterBug meets all USB 2.0
speed specifications. JitterBug's excellent performance is the result of careful
design and craftsmanship, comprehensive technical measurements, and thorough
listening tests. As a result the JitterBug improves dynamic contrast, warmth and
resolution of your audio.
Dual Discrete Noise-Dissipation Circuits: JitterBug's dual-circuitry
works on both the data (communication) and vbus (power) lines of USB ports. The
latter reduces noise and prevents EMI and RFI from contaminating the associated
digital-to-analog converter (DAC) and/or cable. The former minimizes parasitic
resonances created by the computer and USB bus, and is optimized to remove noise
above the USB 2.0 frequency specification, making it ideal for audio playback.
Note: When used with USB 3.0 devices, the JitterBug purposely decelerates the
device to USB 2.0 specifications.
Jitter Reduction: The JitterBug also measurably reduces jitter and
packet errors (in some cases, packet errors are completely eliminated). The
result is a clearer and more compelling sound and overall better audio
USB 2.0 Connectors: The JitterBug features a female USB 2.0 (type-A)
port on one end and a male USB 2.0 (type-A) connector on the other end.
Applications: JitterBug is extremely easy to use and will offer
reliable results for many years to come. It can be used with external USB
digital-to-analog converters (DACs), mobile phones and portable media devices,
and network streaming/storage devices. Use the Audioquest JitterBug in the
- Use one JitterBug in line with any computer and USB DAC
- Use an additional JitterBug in parallel with the first for improved
- Use JitterBug with other locally connected USB devices; such as hard
drives, printers, and cameras, to effectively reduce audio interference.
- Use JitterBug with USB-enabled network devices, such as routers, NAS
devices, and streamers.
- Use JitterBug with mobile devices into audio systems in the home and in
Note: The JitterBug draws no power from the source. It will not inhibit your
mobile device's ability to charge its battery
Optional DragonFly: Audioquest's DragonFly (703DGNFLY2,
sold separately) is a digital-audio converter and headphone amplifier with an
onboard 64-step analog volume control. It has a USB plug at one end and a 3.5mm
minijack at the opposite end. It connects to any Mac or Windows PC and bypasses
the computer's compromised audio circuitry to deliver cleaner, clearer, more
naturally detailed sound to headphones, powered desktop speakers, or complete
audio systems. Insert JitterBug the in series with DragonFly to further reduce
noise and resonances.
