NuForce Icon iDoTM
Audiophile-Grade DAC and Headphone Amp for iPad®, iPhone®
and iPod Touch®.
iDo extracts audio data in its original digital form (in USB
Host mode) from Apple mobile digital devices, delivering
bit-perfect, low-jitter, audiophile-quality music file playback.
The Icon iDo delivers audiophile-grade CD quality sound to
digital music files stored on Apple® mobile digital devices. iDo
is ideal for music enthusiasts and musicians alike who primarily
listen to—and have their digital music libraries stored on—these
Apple products are becoming the hub of a person’s entire music
and audio collection, so improving the audio quality produced by
these devices is key. The Icon iDo delivers on that at very
affordable price point.
A fast and easy connection.
Using the Icon iDo is simple. Users can connect any Apple mobile
device to the Icon iDo with the Apple® approved and included
30-pin sync/charging cable, attach the power supply, and then
plug the Icon iDo into a home stereo system using RCA cables or
a single coaxial. Users can also plug in headphones directly
into the Icon iDo for personal high quality sound playback in a
manner the artist intended it to be heard.
How iDo makes music stored on Apple devices sound
Apple uses its own audio codec, Apple Lossless Encoder (ALE), to
compress and store music files on its devices in original CD
quality without loss. However, even ALE files only sound as good
as the default DAC (digital-to-analog converter) found within
the mobile digital device. Icon iDo bypasses the built-in DAC
and extracts the audio data stored on the device in its original
digital form in USB Host Mode. It then converts the high-quality
files for bit-perfect and low-jitter music playback.
A portable power station for the ultimate headphone
Icon iDo also offers a built-in headphone amplifier capable of
powering power-hungry headsets, giving users a total audio
experience. By properly powering headphones, Icon iDo enhances
the auditory performance of the headphones because optimal
amperage is being delivered to them, allowing for greater audio
