Introduction

Congratulations! With the purchase of the

Harman Kardon TU 970 you are about to begin many years of listening enjoyment.

While sophisticated systems are hard at work within the TU 970 to make all of this happen, hookup and operation are simple.

To obtain maximum enjoyment from your new 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 TU 970 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.

Description and Features

The TU 970 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 favorite program types.A DOT-matrix display brings all this information to you with high visibility.As more FM stations become equipped with RDS capabilities, the TU 970 will serve as an easy to use center for both information and entertainment.

INSTALLATION AND CONNECTIONS 7

Audio Connections

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. Connect the analog output of the TU 970 to the tuner input of your pre amplifier or integrated amplifier.

2. For DAB signals, connect the optical or coaxial digital output of the TU 970 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. Connect it to the AM

terminals



For best reception, place the antenna away from the unit as well as 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 terminals.

4. Connect a 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 adapter to make the connection. The supplied antenna is for indoor use only.

5. Connect a DAB Antenna to the DAB Anten-



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

!8. 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 wall outlet. You’re ready to enjoy the TU 970!
