USER MANUAL T775 DAB NAD

Until now, analogue radio signals such as FM or AM have been subject to numerous kinds of interference on their way from the transmitter to your radio. These problems were caused by mountains, high-rise buildings and weather conditions. With Digital Audio Broadcast (DAB), you can now receive CD-Ike quality radio programs without any annoying interference and signal distortion. DAB broadcasts use digital signals rather than traditional analogue transmissions, thus providing clear high quality reception. You get far more robust reception and virtuall hiss or crackle free sound with DAB as long as you are within à good coverage area With DAB, the listener can scroll through list of avallable stations - then instantly tune to the station of his choice. There is no need either to remember channel frequencies. All broadcasts are selected by simply selecting the service name. The T 775 makes it possible for you to enjoy listening to DAB broadcasts TheT 775 has a Digital Audio Broadcast (DAB) module socket on the rear panel for adding a separately sold and NAD-specified outboard DAB module - the NAD DAB Adaptor DB 1. All the control software for this format is included: just plug-in the module and start enjoying the CD-Ike quality sound and expansive content selection available with DAB.
