The new I-Sonic ES2 includes a second generation HD Radio tuner with full multicasting. With its advanced acoustical system, Digital Signal Processing, and new HD Radio tuner technology, the I-Sonic ES2 is the highest performing self-contained HD Radio product on the market. The I-Sonic ES2 accepts all iPod models with dock connectors in its top-mounted iPod dock hidden beneath a sliding door. S-Video and composite video outputs allow the user to connect a television or video monitor to the IES2 for viewing video content stored on a video iPod. The I-Sonic ES2 introduces a new music discovery feature from Apple called iTunes Tagging which makes it simple to buy songs you hear on HD Radio stations. The iTunes Tag button on the I-Sonic ES2's front panel and remote control allows you to "tag" songs broadcast by HD Radio stations. The I-Sonic ES2 stores information about the tagged songs to its memory and transfers the tags to an iPod when docked. When you sync your iPod with your computer, iTunes automatically presents the songs in a new Tagged play-list for the you to preview, buy, and download. iTunes Tagging is a great way to discover new music and add it to one's collection.
