<b>NuForce Icon iDo</b>
Audiophile-Grade DAC and Headphone Amp for iPad®, iPhone® and iPod Touch®.
- Bit-perfect, low jitter USB Host Mode operation;
- Digitally controlled analog volume control provides precise control, accurate channel tracking and superior resolution;
- 3.5mm headphone output jack;
- 24-bit DAC;
- No sample rate conversion.
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 devices.
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.
<b>A fast and easy connection</b>
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.
<b>How iDo makes music stored on Apple devices sound even better?</b>
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.
<b>A portable power station for the ultimate headphone listening experience</b>
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 clarity.
