2.3.4.3 Setting the Parameters for the AUX inputs (incl. RDS)
1. Select Transmitter > Exciter > Input > Data Input .
The Data Input window opens.
2. Set the parameters as shown in the table below.
Note
The AUX inputs AUX1 and AUX2 have the same priority and identical characteristics.
Typically, the RDS signal is fed in at AUX1 . AUX3 is only available internally in the trans-
mitter.
Note Threshold refers to the total deviation of all AUX channels.
Display/entry Explanation
AUX1 to AUX3
Level For setting the nominal input amplitude
Value range: -18 dBu to -7 dBu (default setting -14 dBu)
Deviation For setting the frequency deviation caused by the nominal input
level
Value range: 2 kHz to 10 kHz (default setting 4 kHz)
Active For activating the corresponding input
Selection: ON/OFF
Threshold For setting the input amplitude threshold for monitoring
– Percentage value range: 2% to 80% (default setting 5%)
– Absolute value range in dBu (the system uses the percentage
value; the absolute value is converted into the corresponding,
rounded-off percentage value)
On-Time If the input amplitude is continuously above the threshold during the
set
On-Time , the input is considered to be OK.
Value range: 1 s to 6000 s (default setting 5 s)
Off-Time If the input amplitude is continuously below the threshold during the
set
Off-Time , the input is considered not to be OK.
Value range: 1 s to 6000 s (default setting 5 s)
