Kathrein UFD 520 manual Frequency left/right, Bandwidth, De-emphasis

Analogue setting

Frequency left/right

Here, you can select one of two sound carriers. For example, in the case of com- mentary channels or film broadcasts in different languages. The setting is made

with the ￿or ￿buttons and the numerical buttons. The initial setting is “7.02 MHz“ and “7.20 MHz“.

Bandwidth

Here, you can select the input bandwidth of the analogue audio receiver, since dif- ferent transponders also have different transmission bandwidths, to which the re- ceiver needs to be tuned.

The following settings are possible:

￿￿130 kHz,

￿￿180 kHz,

￿￿280 kHz,

￿￿300 kHz and

￿￿400 kHz.

The initial setting is “130 kHz“.

DNR

The DNR setting here stands for Dynamic Noise Reduction applied to the audio signal. The effect is similar to that of the Dolby system on cassette recorders. You can select either "ACTIVE" or “INACTIVE”.

The initial setting is “ACTIVE“.

De-emphasis

The de-emphasis compensates for the pre-emphasis on the transmission. The resultant effect is a type of noise suppression. The setting options are possible:

￿￿50 µs,

￿￿75 µs,

￿￿J17 and

￿￿NO DEEMP.

The initial setting “75 µs“.
