Introduction
1.3 Quick set-up guide
Using a transmitter with external audio processor/stereo generator
and with RDS encoder (in-line connection)
Remove the screws that hold the lid of the transmitter and remove the lid.
Locate the main board on the right side of the transmitter. Locate jumper J1 right behind the BNC con-
nectors. Move it to down position (Loop-through off).
Reassemble the lid back on.
Place a transmitter in a well ventilated space. If it's rack-mounted,
leave at least 1U free above and below it for adequate cooling.
Connect the antenna to the RF output N-connector on the back of
the transmitter.
Connect the MPX output of your audio processor (or stereo gen-
erator) to the MPX input of your RDS encoder.
Connect the MPX output of your RDS encoder to the MPX input
on the back of the transmitter.
Plug in the power cord to the transmitter.
Once the transmitter is operating, set the correct carrier frequency from
the front panel (this can also be locked and set internally).
Adjust the desired power output level using front panel. Check reflected power is OK.
Check the modulation level - if the modulation level is low, adjust the MPX output level on your audio
processor (or stereo generator), RDS encoder and/or the MPX input level on the back of the transmitter.
The maximum modulation should not exceed 75kHz.
Check the documentation that came with your audio processor on how to set/check the proper pilot
injection level.
Check the documentation that came with your RDS encoder on how to set/check the proper RDS injec-
tion level.
That finishes the set-up. A much more detailed explanation is available in the appropriate sections of this manual as
well as additional options. You should read through it!
