Audioquest Jitterbug USB Data & Power Noise Filter

• About this item The JitterBug is design 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 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-analogue 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 for audio playback 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 experience. 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 It can be used with external USB digital-to-analogue converters (DACs), mobile phones and portable media devices, and network streaming/storage devices. The JitterBug draws no power from the source. It will not inhibit your mobile device's ability to charge its battery Use one JitterBug in line with any computer and USB DAC (digital-to-analogue converter). Use an additional JitterBug in parallel with the first for improved playback performance. 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 the car ›See more product details.

We're big fans of AudioQuest's award-winning DragonFly plug-in USB DAC (digital-to-analogue converter). Now AQ has developed the JitterBug, an innovative device made to enhance the performance of the DragonFly - or any other USB DAC. You simply plug the ultra-compact JitterBug into the USB port of any computer, DAC, receiver, streamer, NAS device, or car stereo to reduce noise and restore your music's clarity, dynamics, and warmth. You can even connect it to your . The is a dual-function filter that cleans up noise in both the power and data portions of the USB interface. It performs like a line conditioner for the USB voltage bus, as well as acting as a signal filter for the USB data bus. In both cases it suppresses electrical noise that interferes with your DAC's sensitive circuitry. The can reduce timing jitter as well, but it doesn't re-clock the digital audio stream to eliminate jitter. Slightly smaller than the DragonFly, the JitterBug has a male USB plug on one end and a female USB port on the other. If you already own a DragonFly, the JitterBug is an easy. Simply plug into any of your computer's available USB ports, then plug the DragonFly into JitterBug's USB port. If you're using a different USB DAC, you plug the into an available USB port, and use a USB cable to connect the JitterBug to your DAC. The Problem: All computing devices-laptops, s, Network Attached Storage devices (NAS drives), media servers. -inherently generate a significant a of noise and parasitic resonances. Additionally, computers contribute a considerable a of RFI and EMI onto the signal paths-all of which can easily find its way onto your USB cables and into your audio system. This noise and interference has many negative effects. Noise-compromised digital circuitry increases jitter and packet errors, resulting in distortion that causes a comparatively flat and irritating sound.
