Introduction
1.4 Quick set-up guide
Using a transmitter with external audio processor/stereo generator
but without RDS encoder
1.
Remove the screws holding the smaller section of lid (above the power supply module) and place to one
side.
2.
Locate the main board on the right side of the transmitter. Locate jumper
J5 right behind the BNC connectors. Move it to left position (Loop-
through off).
3.
Reassemble the lid back on.
4.
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.
5.
Connect the antenna to the RF output connector on the back of the transmitter.
6.
Connect the MPX output of your audio processor (or stereo generator) to the MPX input on the back of
the transmitter.
7.
Plug the power cord into the power supply module on the rear panel of
the transmitter.
8.
Once the transmitter is operating, set the correct carrier frequency
from the front panel (this can also be locked and set internally).
9.
Adjust the desired power output level using front panel. Check reflect-
ed power is OK.
10.
Check the modulation level - if the modulation level is low, adjust the
MPX output level on your audio processor (or stereo generator) and/
or the MPX input level on the back of the transmitter. The maximum
modulation should not exceed 75kHz.
11.
Check the documentation that came with your audio processor on how to
set/check the proper pilot injection 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!
