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 765 makes it possible for you to enjoy listening to DAB broadcasts.
The T 765 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.
CONNECTING THE DAB MODULE
Plug-in the other end of the DIN connector (supplied with your NAD DAB
Adaptor DB 1) from the DAB module’s output port into the corresponding
DAB module input socket on the rear panel of the T 765. Select DAB mode
on the T 765 by toggling the [AM/FM/DB] button in the front panel.
NOTES
• Please refer to NAD DAB Adaptor DB 1 installation guide for proper setup
connection of the DB1 with respect to the T 765.
• If there is no NAD DAB Adaptor DB 1 connected, the VFD will show
“Check DAB Tuner”.
DAB OPERATION
With the separately sold NAD DAB Adaptor DB1 already connected to the
T 765, you can now carry out the T 765 to receive DAB broadcasts.
1 Toggle [AM/FM/DB] button until DAB mode. The VFD will show“No
Service List”indicating that there are no scanned DAB broadcast
services yet. This is the default mode of the DB1.
2 To tune to DAB broadcast services, press [TUNER MODE] and then
toggle the front panel’s [TUNE / ] to select either “Full Scan” or
“Local Scan”.
FULL SCAN will enable the scanning of the full range of digital
frequencies (Band III and L-Band).
LOCAL SCAN performs local scanning of available DAB services in your
area. Check with your dealer or visit www.WorldDAB.org to check the
applicable digital transmission frequencies in your area.
3 Upon selecting either “Full Scan” or “Local Scan”, automatic scanning
will be performed. This sequence cannot be interrupted. During the
sequence, the following message will be visible in the VFD.
The bars show the progress of the sequence. When scanning is
completed, the last number shown on the right side of the VFD
corresponds to the total number of DAB broadcast stations found. Then,
the rst station is tuned in (See “ALPHANUMERIC”section below to
understand the order or arrangement of stations).
4 The strength of the incoming signal can be shown on the VFD by
pressing the [ENTER] button. The more segments visible in the lower
display line, the stronger the signal. By changing the position of the
antenna, you can increase the signal strength. You can also opt for an
external antenna. Consult an antenna professional for more information.
NOTES
• “No Service List” will also be shown in the VFD when no 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.
• HTR 3’s [MENU/FM MUTE], [ENTER] and [ ] are the equivalent
remote control keys for the front panel buttons [TUNER MODE], [ENTER]
and [TUNE / ]. When using these HTR 3 buttons to navigate DAB
options, ensure that the “DEVICE SELECTOR” setting of your HTR 3 is set
to “TUNER”.

SERVICE LIST
Follow the steps below to select through the DAB service stations found.
1 At DAB mode, press [TUNE / ] to step through the list of
available stations as shown in the lower display line of the VFD.
2 Press [ENTER] to select the desired station.
DAB TUNER MODE
Aside from“Full Scan” and “Local Scan”as already described above, pressing
the [TUNER MODE] button will also present you with other options namely
– Station Order, DRC, Manual Scan, Prune List and Reset
STATION ORDER
Use “Station Order”to sort the sequence of the listed stations. There are
three orders – Alphanumeric, Ensemble and Active.
1 While listening to a DAB broadcast, press front panel’s [TUNER MODE]
button and then [TUNE / ] to select “Station Order”. Press
[ENTER].
2 Toggle [TUNE / ] to select through“Alphanumeric”,“Ensemble”
and “Active”.
3 Press [ENTER] to select desired station order.
ALPHANUMERIC
This is the default setting. Stations are arranged by numbers rst and then
alphabetically by letters.
ENSEMBLE
Digital radio is broadcast as groups of data called ensemble. Each ensemble
contains a number of stations, transmitted at a set frequency. When
“Ensemble”is selected as the mode of station order, the radio stations are
arranged in the order of their ensemble names.
NOTE
Ensemble is also interchangeably termed as “multiplex” by other
broadcast providers.
ACTIVE
Active stations are listed at the top of the channel list. Those channels
that are in list but have no service in the area will be displayed last in the
channel list.
DRC
The level of compression of stations can be set to eliminate the dierences
in dynamic range or sound level between radio stations. Popular music
would normally be more compressed than classical music, resulting in
possible dierent audio levels when changing from one station to the
other. Setting the DRC to “0”means no compression,“1/2”indicates medium
compression and“1”shows maximum compression. No compression is
recommended, especially for classical music.
1 While listening to a DAB broadcast, press front panel’s [TUNER MODE]
button and then [TUNE / ] to select “DRC”. Press [ENTER].
2 Toggle [TUNE / ] to select through“DRC 0”, “DRC ½”and “DRC 1”.
3 Press [ENTER] to select desired DRC level.
MANUAL SCAN
This option allows you to directly tune to a desired channel and include it
in the service list (if not yet available at the time). You can also use manual
scan to assist you in positioning the DAB antenna for best reception of the
desired channel.
1 While listening to a DAB broadcast, press front panel’s [TUNER MODE]
button and then [TUNE / ] to select “Manual Scan”. Press
[ENTER]. The current channel and frequency are shown in the upper line
of the VFD. The “bars”at the lower line of the VFD indicate the signal
strength level of the current channel.
2 To select other channels, toggle [TUNE / ] to step through the
channel list. Release [TUNE / ] when you have arrived at your
desired channel. Channel and frequency are shown in the upper line
of the VFD. The “bars”at the lower line of the VFD indicate the signal
strength level of the current channel. To improve the reception of the
selected channel, adjust or reposition the DAB antenna until the best
reception is indicated.
3 Press [ENTER] to tune the selected channel.
NOTE
The number of ensembles and stations that could be scanned will vary
depending on your location.
