Overview

Our take on the AudioQuest JitterBug™

We're big fans of AudioQuest's award-winning DragonFly® plug-in USB DACs (digital-to-analog converters). Now AQ has developed the JitterBug, an innovative device made to enhance the performance of the DragonFly Red v1.0, DragonFly Black v1.5, 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 smartphone.

An easy sonic upgrade for your USB DAC

We're big fans of AudioQuest's award-winning DragonFly® plug-in USB DACs (digital-to-analog converters). Now AQ has developed the JitterBug, an innovative device made to enhance the performance of the DragonFly Red v1.0, DragonFly Black v1.5, 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 smartphone.

How does it work?

The JitterBug 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 JitterBug 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, affordable upgrade. Simply plug JitterBug 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 JitterBug into an available USB port, and use a USB cable to connect the JitterBug to your DAC.

Features

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 experience.

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 following applications.

  • Use one JitterBug in line with any computer and USB DAC (digital-to-analog 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.
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.
