What is DAB system?
DAB can deliver CD quality sound without any annoying interference and signal distortion.
Furthermore, it can carry text, pictures, and data. In contrast to FM broadcast, where each
programme is transmitted on its own frequency, DAB combines several programmes (called
"services") to form one "ensemble." In addition, each "service"—called "primary service"—
can also be divided into its components (called "secondary service"). A typical ensemble has 6
or more programmes (services) broadcast at the same time.
It is recommended to use DAB (Digital Audio Broadcasting) tuner KT-DB1500 or
KT-DB1000 with this unit. If you have another DAB tuner, consult your JVC IN-CAR
ENTERTAINMENT dealer.
• Refer also to the Instructions supplied with your DAB tuner.

When surrounding sounds are noisy

interfere with your listening. Especially the low

If this happens, you can reinforce the low level
sounds to improve your listening to.

Dynamic Range Control signals together with
their regular programme signals.
