The size and shape of a USB thumb-drive, DragonFly Red is a digital-to-analog converter with a USB plug at one end and a 3.5mm mini-jack at the opposite end. Compatible with Apple OS X and Windows (7, 8.1, 10) PCs, DragonFly Red can be plugged into a USB port to bypass the host computer's compromised audio circuitry and deliver cleaner, clearer, more naturally beautiful sound to headphones, powered speakers, or complete audio systems. Thanks to its low-noise, high-efficiency Microchip microcontroller, DragonFly Red draws extremely low power from the host, enabling seamless compatibility with Apple iOS and Android mobile devices. DragonFly Red requires no additional drivers and plays all digital files-from MP3 to high-res (with native resolutions up to 24 bits and 96kHz). It features StreamlengthTM asynchronous USB code, which ensures low jitter, low resource load, minimal packet errors, world-class audio playback, and reliable connectivity between DragonFly and any computing device compliant with USB Host Mode. DragonFly Red's 32-bit ESS 9016 DAC chip uses a sophisticated minimum-phase digital filter to provide more naturally detailed and dynamic music, while the bit-perfect digital volume control enables maximum resolution regardless of volume setting: With DragonFly Red connected to a PC or mobile device, adjusting the host's volume control will adjust DF Red's onboard volume. With an output of 2.1 volts, DragonFly Red delivers enough power to successfully drive all preamplifier, integrated amplifier, or receiver inputs, as well as a wide range of today's headphones, including power-hungry models. AudioQuest's free Desktop Device Manager application allows for software upgrades to meet future technological advancements. With DragonFly Red, music lovers can enjoy an emotionally compelling listening experience, at home or on the go, with the computer or mobile device of their choice.
