Why is "Format" important?

CD's are 44100 Hz.

Compressed MP3 and AAC music files and

audio streams are typically encoded at three

different quality levels - 128kbps, 256kbps

(iTunes Plus) and 320kbps - and most often

reconstructed as 44100 Hz files.

Many music downloads and CDs ripped as

Apple Lossless or FLAC files are reconstructed

to 44100 Hz.

If you have higher resolution files, it is

important to choose the correct higher sample

rate in order to maximize the benefit of

those files, and to direct the information to

whichever of DragonFly's two dedicated

"clocks" is optimized for that sample rate.

Some programs (such as NPR) use 48000 Hz.

These 24-bit/48000 Hz files can sound

amazingly close to higher sample rate files.

The AudioQuest DragonFly

is added as "Speakers."

Ensure it is the "Default

Device."

Select "Speakers."

Click "Properties" button for

more setup options.

Click "Advanced" tab.

Use the dropdown menu to

choose the sample rate ...

most likely 24-bit, 44100 Hz;

please read explanation

below.

For "Exclusive Mode," check

both options then click

"OK."

Some "high-res" files use 88200 Hz, but

Windows 7 is not currently compatible with

this sample rate. To play 88200 Hz music files,

Windows 7 users must select 44100 Hz, 48000

Hz, or 96000 Hz with 44100 recommended

as optimal. Windows-compatible alternative

music players such as JRiver and foobar2000

will play 88200 Hz files at their native sample

rate. For support or more information about

these music players please visit jriver.com or

foobar2000.org.

Some "high-res" files use 96000 Hz because it

is a multiple of the sample rates used on DVDs,

Blu-rays and in the computer world.

DragonFly's illuminated dragonfly lights up in

different colors to indicate status or sample rate:

Red: Standby Green: 44100 Hz

Blue: 48000 Hz Amber: 88200 Hz

Magenta: 96000 Hz
