4.3. Input selection
The input can be set to:
•
Line1 for the analog inputs (see sections 4.5 to 4.7)
•
Line2 for the AES (see sections 4.5 to 4.7)
•
MPX1 and MPX2 inputs (see sections 4.4 and 4.7)
•
Internal generator
4.4. Setting the MPX inputs
•
Set the drive before processing between -6 and +6 dB
•
Set the nominal level between -50 and +50 dBu
•
Set the input type:
o
"MO" for mono
o
"ST" for stereo
o
"ST+R+S" for RDS+SCA
o
"ST+R" for RDS
o
"RDS" for RDS
o
"RDS+SCA" for RDS+SCA
o
"SCA" for SCA
The corresponding filter will be applied.
4.5. MPX configuration
•
Set the audio type to:
o
STEREO
o
MONO
o
MONO_L
o
MONO_R
Selecting STEREO enables the internal 19 kHz; you will therefore want to select MONO for an MPX
input.
•
Set the total deviation between 0 and 150 kHz
•
Set the pilot deviation between 0 and 25.5 kHz
•
If internal RDS is needed, set the RDS encoder deviation between 0 and 25.5 kHz (recommended
deviation is 4 kHz)
•
Set the max excursion between 0 and 200 kHz
4.6. Setting the analog or AES inputs
Use the LINE1 commands for the analog inputs.
Use the LINE2 commands for the AES inputs.
•
Set the drive before processing between -6 and +6 dB
•
Set the nominal level between -50 and +50 dBu
•
Set the pre-emphasis to 0, 50 or 75 µs depending on your country (50 µs in Europe, 75 µs in the
USA).
4.7. Getting on air
1. Disable the RF to turn off the transmitter using the front panel RF key.
2. Make sure the RF indicator LED is off.
3. Disconnect the load and connect the antenna to the transmitter RF output.
