Headphone amp for select Apple iPads, iPhones, & iPods. Featuring
audiophile-grade 24-bit D/A converters, the iDo extracts the original digital
audio data from your compatible Apple device and then coverts the digital audio
data to a high-quality analog signal for use with headphones or your home stereo
system. The iDo offers a built-in
headphone amplifier capable of powering hard-to drive headphones to their full
potential. The iDo's analog RCA & digital S/PDIF connectors interface with your
home stereo system. The iDo is ideal for music enthusiasts who primarily listen to

Note: The NuForce icon iDo is designed to work only with Apple iTunes &
iPod software. Apple iPod/iPhone software updates may change functionality
results. If you download a newer software version, you may need to reset the
device and your iPod/iPhone to regain functionality. If this doesn't work,
you may need to revert to the older software version or wait until a newer
software update is available.
24-bit DAC: The NuForce icon iDo features audiophile-grade 24-bit D/A
converters that operate exclusively at the data's native sample rate for
bit-perfect, low-jitter music file playback (no sample rate conversion). The iDo
extracts audio data in its original digital form (in USB Host mode) from your
Apple mobile digital device, delivering bit-perfect, low-jitter,
audiophile-quality music file playback. As a result, the icon iDo delivers
audiophile-grade CD quality sound to digital music files stored on your Apple
mobile digital devices.
Note: The maximum sample rate currently supported by Apple is
16-bit/44.1kHz or 24-bit/48kHz.
iPod DAC Bypass: 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. The
icon iDo bypasses the built-in DAC & 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 & low-jitter music playback.
Headphone Amp: The 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, the icon iDo enhances the auditory
performance of the headphones because optimal amperage is being delivered to
them, allowing for greater audio clarity. The icon iDo is equipped with a 3.5mm
headphone jack to connect a set of headphones for private high-quality sound
playback.
Analog & Digital Outputs: The NuForce icon iDo is fitted with an
analog stereo RCA output & a digital coaxial output. The icon iDo plugs into
your home stereo system using stereo RCA cables or a single coaxial cable (both
sold separately).
Digitally Controlled Volume Control: Digitally controlled analog
volume control provides precise control, accurate channel tracking, & superior
resolution. The volume is set to 10% when the iDo is turned on. The volume level
is indicated by the relative position of the Blue LED indicator on the
front-panel.
External Power Supply: The NuForce icon iDo operates off of standard
household current using the supplied AC power adapter. The external power
adapter is separate from the icon iDo to further improve sound quality.
Note: Power button is located on back of unit.
