LISTEN TO THIS!

Stop. And listen. Imagine a place where you can hear CD-quality music, choose from hundreds of stations and see the artist name and title on your screen—all without interference. Welcome to the world of digital radio. With millions of people around the world now able to receive digital radio transmission, crystal clear sound is well within your reach.

Digital radio is taking the old broadcast media into the digital age. Digital radio is almost immune to the sort of interference that can make listening to today’s conventional AM or FM radio less than satisfying. If you listen to FM in the car, you may have noticed hisses and pops as you drive along. That’s caused by multipath interference when the FM signal bounces off buildings, trees and hills and arrives at your receiver out of phase with the main signal, confusing the transmission. Digital radio corrects this, which means that even in the most difficult listening environments—the center of a city with high-rise apartments and office buildings—the digital radio signal remains absolutely perfect. Digital radio also provides additional content, currently not available on the AM/FM dial. And, new features such as on-demand radio, surround sound and rewind radio are possible with digital radio.

Two standards lead this listening revolution. Eureka-147 Digital Audio Broadcasting (DAB) broadcasts in several countries: the United Kingdom, Germany and Canada. And it’s found in Asia in such places as Singapore and Taiwan. In the U.S., HD Radio™ technology is the FCC-selected standard for digital audio broadcasting. So today, wherever you are, wherever you …you can be enthralled by the wonderful world of digital radio.
