NAD T 747 User Manual

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-like 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 virtually hiss or crackle
free sound with DAB as long as you are within a good coverage area.
With DAB, the listener can scroll through a list of available 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 747 makes it possible for you to enjoy listening to DAB broadcasts.
The T 747 has a Digital Audio Broadcast (DAB) module socket on the rear
panel for adding a separately sold and NAD-specied 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-like
quality sound and expansive content selection available with DAB.
IMPORTANT NOTICE
Unless otherwise specically stated, navigating or accessing DAB
functions can be undertaken by using either the AVR 3 remote control
or the front panel buttons. If the control button or icon button being
referred to is available on the AVR 3 remote control and front panel,
then the reference to said button is applicable to both the AVR 3 remote
control and front panel.

DAB OPERATION
With the separately sold NAD DAB Adaptor DB1 already connected to the
T 747, you can now carry out the T 747 to receive DAB broadcasts.
1 Toggle [AM/FM/DB] button until DAB mode. When DAB mode is selected,
VFD will show “DAB initialize – Please wait” and then go to “Full Scan” mode.
“Full Scan” will take at least 20 seconds or more to complete. FULL SCAN
will enable the scanning of the full range of digital frequencies (Band III and
L-Band). This sequence cannot be interrupted.
The arrows show the progress of the sequence. When scanning is
completed, the last number shown on the upper right side of the VFD
corresponds to the total number of DAB broadcast stations found.
Then, the rst station is tuned in (See “ALPHANUMERIC” description
below to understand the order or arrangement of stations).
2 The strength of the incoming signal can be shown on the VFD by
pressing the [ENTER] button. The more “o” segments visible in the lower
display line, the stronger the signal. By changing the position of the
antenna, you can increase the signal strength. Consult an antenna
professional for more information.
NOTE
“No stations Available” will be shown in the VFD when no DAB
stations are found after the scanning process. If this occurs, check the
connection and position of the DAB antenna or call your local DAB
broadcast providers for coverage information.
