Modulator connection
Stereo reproduction is not possible if the receiver signal is routed via the
modulator. These settings will then be ineffective.

Here you can select between two sound carriers, e.g. for commentary channels or
films broadcast in different languages. The required settings are entered by
pressing the
-
or
+
buttons and the number buttons.
The basic setting is "7.02 MHz“ and "7.20 MHz“
Bandwidth
Here you can select the reception bandwidth of the analogue audio receiver as
various transponders have different transmission bandwidths to which the receiver
must be tuned.
The following settings are possible:
•
130 kHz,
•
180 kHz,
•
280 kHz,
•
300 kHz and
•
400 kHz.

DNR
This setting is the dynamic noise reduction for the audio signal. The effect is similar
to that of the Dolby system on cassette recorders. You can select between
"ACTIVE" and "INACTIVE".
The basic setting is "ACTIVE".

De-emphasis compensates the transmitter pre-emphasis. This feature is a type of
noise suppression function. The possible settings are:
•
50 µs,
•
75 µs,
•
J17 and
•
NO DEEMP.
The basic setting is "75 µs“.
