Setting Up DragonFly

DragonFly is designed to be "plug and play" with all major desktop and mobile devices

and operating systems, such as Android, Apple, and Microsoft Windows 10 DragonFly

requires no additional drivers to operate with any of these systems

Note: DragonFly employs a bit-perfect digital volume control that resides inside of

the DAC chip itself—a sophisticated implementation that ensures maximum fidelity,

dynamic contrast, and signal-to-noise ratio With DragonFly connected to a PC or

mobile device, adjusting the host's system volume control will, through proxy, control

the DragonFly's onboard volume

The Importance of Format

CDs operate at a sampling frequency of 44 1kHz Compressed MP3 and AAC music files

and audio streams are typically encoded at one of three different quality levels—128kbps,

256kbps, or 320kbps—and are most often reconstructed as 44 1kHz files Similarly, many

music downloads and CDs ripped as Apple Lossless or FLAC files are reconstructed to

44 1kHz For these reasons, DragonFly will often produce the best results when your

computer is set to output a sample rate of 44 1kHz If you have higher resolution files,

however, it is important to choose the correct higher sample rate in order to maximize

the benefit of those files For the best performance with sampling rates above DragonFly

Cobalt's 96kHz ceiling, files should be played at a rate mathematically related to their

native resolution For instance, a 192kHz file should be played at 96kHz (i e , 2 x 96000 0

= 192000 0)

There are many applications available (such as Roon, BitPerfect, Foobar, JRiver, Audirvana,

Decibel, Amarra, etc ) that will automatically set the sample rate of DragonFly to that of

the file, eliminating the need for manual setting of the sample rate

DragonFly's LED lights up in different colors to indicate status or sample rate:

Red: Standby

Amber: 88 2kHz

Green: 44 1kHz

Magenta: 96kHz

Blue: 48kHz

Purple: MQA

Note: DragonFly is an MQA renderer only and must be partnered with appropriate

software to unfold MQA files For MQA capabilities, please consult the user

manual of your playback device and music-player application
