Preset Tune
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 is does not broadcast, the display will
show
STATION NOT AVAILABLE
.
Software Version
This section allows a visual check of software
version installed in your TU 970. This might be
helpful in case servicing of your tuner may be
necessary.
Dynamic Range Control (DRC) Value
In this section you can set the level of compres-
sion of stations to eliminate the differences in
dynamic range or sound level between radio sta-
tions. 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, and make
therefore sure that amplifier levels are not set
too high when changing from one station to
another.
Manual Tune
In this section you can activate Manual Tuning,
in case the Autotune function is unable to find
any stations. You can also use Manual Tuning to
assist in positioning the antenna for best recep-
tion of a specific station.
FM/AM Tuner Operation
