THANK YOU FOR CHOOSING NAD
Congratulations! With the purchase of the C445 Tuner you are about to begin many years of listening enjoyment.
While sophisticated systems are hard at work within the C445 Tuner to make all of this happen, hook-up and operation are simple.
To obtain maximum enjoyment from your new C445 Tuner, we urge you to take a few minutes to read through this manual. This will ensure that
connections are made properly. In addition, a few minutes spent learning the functions of the various controls will enable you to take advantage of
all the power the C445 Tuner is able to deliver.
If you have any questions about this product, its installation or operation, please contact your dealer. He is your best local source of information.
One more thing: We urge you to register your C445 ownership on the NAD Worldwide Web site:
For warranty information contact your local distributor.
DESCRIPTION AND FEATURES
The C445 Tuner is equipped with DAB (Digital Audio Broadcast) and RDS (Radio Data System), bringing a wide range of information to radio listeners.
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 DAB, you can now receive CD-like quality radio programs without any annoying interference and signal distortion.
Now in use in many countries, RDS is a system for transmitting station identification, a description of the station's program type, indication of national,
regional or local programs and the correct time. RDS also allows you to search for favourite programme types. A DOT-matrix display brings all this
information to you with high visibility. As more FM stations become equipped with RDS capabilities, the C445 will serve as an easy-to-use centre for
both information and entertainment.

Introduction
INSTALLATION AND CONNECTIONS
AUDIO CONNECTIONS
DAB ANTENNA
After unpacking the unit and placing it on a solid surface capable of
supporting its weight, you will need to make the connections to your
pre amplifier or integrated amplifier. These steps need to be done only
when the tuner is first installed.
AUDIO EQUIPMENT CONNECTIONS
We recommend that you use high-quality interconnect cables when
making connections to source equipment and recorders to preserve the
quality of the signals.
When making connections to audio source equipment it is always a
good practice to unplug the unit from the AC wall outlet. This prevents
any possibility of accidentally sending audio or transient signals to the
speakers that may damage them.
1
2
Connect the analogue output of the C445 to the tuner input of your
pre amplifier or integrated amplifier.
For DAB signals, connect the optical digital output of the C445 Tuner
to an optical digital audio input of your pre amplifier or integrated
amplifier, if available.
3
Assemble the AM Loop Antenna supplied with the unit as shown
below.
DAB AND FM VHF EXTERNAL ANTENNA
Connect it to the AM terminals.
4
5
Connect an FM Antenna to the FM Antenna connection. The FM
antenna may be an external roof antenna, an inside powered or wire
lead antenna or a connection from a cable system. Note that if the
antenna or connection uses 300-ohm twin-lead cable, you need to
use a 300-ohm-to-75-ohm adaptor to make the connection. The
supplied antenna is for indoor use only.
Connect a DAB Antenna to the DAB Antenna connection. The
supplied antenna is for internal use only. Fix it to the wall in a vertical
direction. The strength of the incoming signal can be shown on the
Information Display by pressing the Select button. The more segments
are 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, available at your dealer.
When all connections are complete, plug the power cord into a non-
switched 230 Volt AC For best reception, place the antenna away from
wall outlet.
For best reception place the unit as far as possible from sources of RF
emissions such as a television or computer. It should also be placed away
from contact with any metal object. In areas where signals are weak, an
outdoor antenna may improve sound and reception quality. Connect
the antenna making certain to also connect a ground wire to the GND
(ground) terminals.

Operation
BASIC OPERATION
INFORMATION SETTINGS
PRESET TUNE
The DAB signal contains besides the radio station additional
information. This information can be made visible in the lower display
line of the Information Display.
In this section you can tune presets of stations that broadcast only
periodically, stations which were not found during the Autotune
process. If you return to this preset in the future, and at that time there
is no broadcast, or the broadcast signal strength is poor, then the display
will show STATION NOT AVAILABLE.
The following information is available to display:
1
2
3
Dynamic Label Segment (DLS): scrolling text, supplied by the
broadcaster.
Program Type: describes the type of broadcast, e.g. Pop Music or
Drama.
Multiplex Name: will show the name of the multiplex of the
broadcaster.
DYNAMIC RANGE CONTROL (DRC) VALUE
In this section you can set the level of compression of stations to
eliminate the differences in dynamic range or sound level between radio
stations. Popular music would normally be more compressed than
classical music, resulting in possible different 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. Note that other radio stations may be far louder, so
make sure that amplifier levels are not set too high when changing from
one station to another.

RDS DISPLAY OPTIONS
PROGRAM SEARCH (PTY)
When an RDS station is tuned, press the INFO Button on the remote
control or on the front panel to cycle through the RDS displays in the
following order:
A major benefit of RDS is its ability to encode broadcasts with Program
Type (PTY) codes that indicate the type of material being broadcast. The
following list shows the abbreviations used to indicate each PTY along
with an explanation of the PTY:
•
•
The Program Service or Station Name.
The current time of the day CLOCK TIME as transmitted by the
station. It will take 3-5 seconds for the time to appear. In the
meantime the word RDS CLOCK TIME will flash in the display.
Note that the accuracy of the time message is set by the radio
station, not by the C445 Tuner.

The Program Type (PTY) as shown in the following list in this
manual.
A Radio Text message, containing special information from the
broadcast station. Note that this message will scroll across the
display to permit messages longer than the positions in the
display. It will take 3 seconds for the text message to appear, in
the meantime the word RDS RADIO TEXT will flash in the display.
If no Radio Text is available, the display will show the Program
Service (Station Name).
•
•
Traffic Announcement. When selected, TRAFFIC ANNOUNCE will
blink for 3 seconds. After 3 seconds, the tuner will scan the FM
band searching for available traffic announcements.
The station's frequency. Some RDS stations may not choose to
include some of these additional features. If the data required for
the selected mode is not being transmitted, the Information
Display will show a NO PTY, NO TEXT or NO TIME message after
the individual time out or will switch back to the previous display.
For any FM station the RDS function requires a strong enough
signal for proper operation. If you receive a partial message or see
any RDS indicator going on and off, try slowly adjusting the
antenna to improve the signal strength or tune to another,
stronger, RDS station.
