Modulator connection

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

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.

∙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".
