WARSANIS 1401FM USER MANUAL

 

 

 

 

OPERATION

 

Make sure the Warsanis 1401FM bypass switch is switched to OPERATE. The first 
stage of the setup is the AGC.  Use normal program material. Adjust the DRIVE 
LEVELER to get approximately 4 to a maximum of 8 dB gain reduction on the led bar 
of the leveler. Watch the led bar for a longer period of time if possible on music and 
speech. This first step is very important for the rest of the processing unit. 
 
Now you can set one of the recommended settings in the Warsanis 1401FM. 
 

The Bypass switch has only effect on the analog XLR outputs. The signal 
comming into the stereo generator will still be processed to prevent 
overmodulation!

 

 

DENSITY SWITCHES

 

One of the functions is the possibility to change the density per band. The density 
switches are located on the >processing board= PCB (fig. Boards). There are four 
switches; one for each band. Each switch has three positions. Changing the switches 
can be done on air. Be careful when you change the density switches. 
 

STEREO TRACKING JUMPERS

 

It's possible with the Warsanis 1401FM to link left and right channels per band 
individually. This means that for example you can link the left and right channel of 
band four (high) and leave the other three bands not linked! This special future gives 
you more control over your sound. If you stereo link a channel it tracks the stereo 
definition resulting in better stereo but lower average loudness. The shipped setting is 
enabled. 
 

LOUDNESS CLIPPING

 

The setting of the loudness clipping control mostly depends on how competitive your 
market is. More loudness clipping means a louder but also more distorted signal. Try 
to find a balance (trade off) between quality and distortion. Voices are mostly more 
affected by the loudness clippers than music. Setting of the loudness clipping drive 
should be done subjectively and over a period of time. Try a recommended setting 
and start working from there. 
 

TRANSMITTER LIMITERS/CLIPPERS

 

If an external stereo generator is used and there is a limiter after the Warsanis 
1401FM that you cannot defeat, set the Multiband Clipping to the maximum (+4) to 
prevent the transmission limiter from being operative. Be also very careful with the 
output gain, too much output gain causes the transmission limiter to react which 
decreases the performance of the Warsanis 1401FM and the on-air loudness. 
 

If possible, use the internal stereo generator of the Warsanis 1401FM. This  
results in a louder on air sound and a better peak control.
