Dab Tuner Operations; Tuning In To An Ensemble And One Of The Services - JVC KS-FX945R Service Manual

DAB TUNER OPERATIONS

We recommend that you use DAB (Digital Audio
Broadcasting) tuner KT-DB1500 or KT-DB1000
with your unit.
If you have another DAB tuner, consult your JVC
IN-CAR ENTERTAINMENT dealer.
• Refer also to the Instructions supplied with
your DAB tuner.
What is DAB system?
DAB is one of the digital radio broadcasting
systems available today. It 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").
With the DAB tuner connected with this unit,
you can enjoy these DAB services.
Note:
When reception switches between DAB and FM, the
listening volume level may increase or decrease
inconveniently. This change in the volume level results
from unequal audio injection levels at broadcaster
site, but not from the malfunction of this unit.
To prevent this inconvenience, you can adjust the DAB
volume level. (See "To adjust the DAB volume level"
on page 39.)
