WARSANIS 1401FM USER MANUAL
SETUP & OPERATION
The Warsanis 1401FM is very easy to a setup. You will need 15 to 30 minutes to set
up the entire system.
INSTALLING THE 1401FM

PREPARATION

Make sure your transmitter or STL link has a flat input and that all pre-em-
phasis, low and highpass filters and transformers are defeated or removed
and that all jumpers are set to your requirements.
Connect one of the Composite outputs of the Warsanis 1401FM directly to the
BNC connector of the baseband input of the transmitter using a short length of
coaxial cable. The maximal length of the cable must not exceed 15 metres (50
feet). At this stage do not connect your SCA generator to the stereo
generator when setting up the Warsanis 1401FM.

LINE UP

This is one of the most important steps of installing the Warsanis 1401FM. The
Warsanis 1401 Stereo Generator has a build-in tone generator that produces
a 400Hz sinus wave of 100% modulation including the 19kHz pilot tone
(without SCA subcarrier).
Turn off the power and open the cover and switch on the sinus generator by
using the switch on the Stereo Generator board and by moving one jumper
(see Fig. Stereo Generator). Turn the power back on. If the sinus generator is
switched on, the audio inputs of the stereo generator are connected to earth.
This prevents any signal coming into the stereo generator influencing the
100% output generated by the sinus generator.
Connect a modulation monitor to the transmitter or receiver and adjust the
composite output of the stereo generator to produce 100% modulation. This
can be achieved by using the plastic screwdriver increasing or decreasing the
multi turn cermet trimmers at the back labelled composite output (1 or 2,
depending on which BNC output is being used).
The stereo generator is calibrated with a pilot injection of 9%. This injection is
user adjustable between 7% and 10% by a R51 (See Fig. Stereo generator).

COMPOSITE STL LINK

If a composite STL link is being used, adjust the composite output of the
stereo generator for 100% modulation on your composite STL transmitter.
After that, adjust your composite STL receiver output or transmitter input for
100% modulation on your transmitter composite meter or modulation monitor.
