AudioQuest DragonFly® Red v1.0

Features

USB DAC + Preamp + Headphone Amp: The AudioQuest DragonFly Red is a sleek, flash-drive sized USB DAC+Preamp+Headphone Amp that delivers far superior sound by bypassing the poor quality sound card that is built into your Apple iOS and Android smartphone/tablet or Windows and Mac laptop/desktop computer; turning your device into a true high-fidelity music source. Its 3.5mm port is designed specifically to connect to an external audio system such as headphones, powered desktop speakers, or your HiFi audio system.

• Apple Compatibility: Compatible with Apple iOS 9.2+ devices that have Lightning connector (not compatible with 30-pin Apple devices). The preferred method for connecting an Apple iOS device is using Apple's Lightning to USB 3 camera adapter (472LTUSBC3, sold separately). Your Apple iOS device's battery will even charge while connected.
• Android Compatibility: Compatible with most Android devices running Jelly Bean 4.1 or newer using the DragonTail USB adapter (703DTAILAN, sold separately). If the DragonFly Red seems to have too little output, then download the the USB Audio Player Prop app which includes its own USB audio driver. This application is compatible with various audio formats and will manage music on both the Android's internal memory and inserted microSD card. Additionally, with your Android phone connected to a WiFi network, this app can find and connect to DLNA servers/libraries, plus support playback of Tidal (UAPP does not offer support for any other 3rd-party applications).
• Windows Compatibility:  Compatible with Windows PC (XP/7/8.1/10). No additional drivers are required for DragonFly Red to operate with Windows PC.
• Mac Compatibility: Compatible with Mac computers (OS X 10.6.8-up). No additional drivers are required for DragonFly Red to operate with Mac OS X.

High-Performance Microcontroller: AudioQuest and DragonFly designer Gordon Rankin worked alongside Microchip Technology to develop a new high-performance, full-speed USB microcontroller solution that delivers improved signal-to-noise ratio and significantly lower power consumption. Drawing 77% less current than the previous microcontroller, the new Microchip PIC32MX microcontroller enables true compatibility with Apple iPod/iPhone/iPad and Android smartphones/tablets. In addition, the Microchip's ultra-low-noise power supply minimizes the sound-degrading effect of high-frequency interference on the critical audio signal.

32-Bit ESS Sabre 9016 DAC: At the heart of DragonFly Red is a 32-bit ESS Sabre 9016 DAC that uses a sophisticated minimum-phase digital filter to provide more naturally detailed and dynamic music. This high-performance DAC is typically found in today's higher-end CD and Blu-ray players. DragonFly Red can accept audio and music files ranging from MP3s (128/256/320kbps) and CD-standard 16-bit/44kHz to native 24-bit/96kHz high-resolution, regardless of music file format. DragonFly Red will accept almost any audio you want to play on your computer and make it sound dramatically better, whether your listening pleasure is iTunes or streaming music services such as Pandora, Spotify, Amazon, or Tidal.

Streamlength Asynchronous USB: Timing errors such as "jitter" have long been the plague of digital audio playback; never more so than in recent years as computers, laptops, tablets, and smartphones have been pressed into service as audio source components. Rather than sharing crucial audio "data clocking" functions with your source device, DragonFly Red uses a very sophisticated Streamlength Asynchronous USB audio data transfer protocol which takes command over the timing of the audio data transfer, dramatically reducing digital timing errors. As a result, you get low jitter, low resource load, minimal packet errors, world-class audio playback, and reliable connectivity between the USB DAC+Preamp+Headphone Amp and your smartphone, tablet, laptop, or desktop computer.

Hybrid-PLL Clock System: The DragonFly Red employs a unique clock system called a Hybrid-PLL. While not discrete, the Hybrid-PLL performs equal to, or better than, many discrete clock systems.

Compatible Sampling Frequencies: DragonFly Red will play music or audio data at 44.1kHz, 48kHz, 88.2kHz, or 96kHz. However, for the best sonic results your smartphone, tablet, laptop, or desktop computer should be configured so that it sends music and audio data to DragonFly Red that matches the "native rate" of the music. For example, since all CDs and music files purchased from iTunes are at a 44.1kHz sample rate, for many people 44.1kHz will be the best sample rate since this is the "native rate" of most digital music. Choosing a higher sample rate will convert your native music and audio data using mathematical approximations that can potentially decrease the sound quality. Conversely, if you have purchased high-resolution music files (96kHz), such as those available from HDtracks.com, configuring your computer for 44.1kHz (or any other lower sample rate) will cause the computer to down-sample your music to a lower resolution. When possible, always configure the computer to output the native sample rate of the music you are listening to.

Note: If you have purchased a file that has a higher sample rate than 96kHz you need to configure your smartphone/tablet or computer/laptop to send DragonFly Red audio data at a resolution no greater than 96kHz, and for the best performance the sample rate you choose should be exactly half the sample rate of the file you're playing. For example; if you purchased a 24-bit/176.4kHz file, 88.2kHz should be selected, whereas if you purchased a 24/192kHz file, 96kHz should be selected. Directly divisible sample rates prevent the computer from doing sonically degrading, complex math in its conversions and allows DragonFly Red to sound its best.

MQA Firmware Update: The latest firmware update (1.06) will provide the DragonFly Red with the capability of rendering Master Quality Authenticated (MQA) files. This means that now the DragonFly Red lets you experience your favorite albums and songs in the highest audio resolutions available. As an MQA-rendering DAC, the DragonFly Red must be used with an MQA-approved playback application, such as Tidal or Audirvana (with more to come), in order to unlock the full resolution of an MQA file.

Note: When rendering MQA files, the DragonFly Red will display a purple light. (Sampling rates of 96kHz will continue to display in magenta.) While the DragonFly Red will not specify the native resolution of the associated MQA file, you can rest assured that the MQA file was derived from the highest source resolution available.

Digital Bit-Perfect Volume Control: AudioQuest's DragonFly Red is equipped with a 64-step, 64-bit, bit-perfect digital volume control. With DragonFly Red connected to a PC or mobile device, adjusting the host's system volume control will, through proxy, control the DragonFly Red's onboard volume. This ensures maximum resolution and the highest sound quality, regardless of volume setting.

Direct Coupled Analog Circuits: DragonFly Red's analog circuits are direct-coupled from the ESS converter chip's output, avoiding the need for any extraneous, sonically degrading components in the signal path.

Stereo Minijack Output (2.1-Volt): DragonFly Red is fitted with a stereo female minijack (3.5mm) output and will output 2.1-volts, which is enough power to successfully drive most preamplifier input circuits and a wide range of today's headphones. The DragonFly Red's 3.5mm output can be used as a Headphone Jack, a Variable Out, or a Fixed Output.

• Headphone Out: DragonFly Red is versatile enough to drive virtually any headphone on the market today. DragonFly Red can drive any headphone from 12-ohm impedance on up. DragonFly Red has enough output to drive even the lowest efficiency headphones.
• Variable Out: DragonFly Red can be used in "variable" output mode with computer-controlled analog volume control when connected directly to powered speakers or a power amplifier.
• Fixed Out: Connecting to a traditional preamplifier or AV receiver, DragonFly Red can be set to a "fixed" output mode by turning the volume to maximum, allowing it to behave like a CD or Blu-ray player.

LED Indicator: A smart LED indicator behind the DragonFly Red icon shows the resolution of the incoming signal - 44.1kHz (green), 48kHz (blue), 88.2kHz (amber), and 96kHz (magenta). Red indicates standby mode.

Firmware Software Upgrades: The DragonFly Red is firmware/software upgradeable through a complimentary Windows PC or Mac OS X desktop application. As new developments arise in music player applications, streaming protocols, or other associated software; DragonFly Red users will be able to incorporate those updates to their existing devices.
