INTRODUCTION

 

The Warsanis 1401FM is an integrated multiband audio processing system for FM 
radio that replaces all others compressors, limiters, clippers, the stereo generator 
and filters. It can be installed either at the studio site using the analog stereo outputs 
or the transmitter site using the composite outputs. It can also be used for a compos-
ite baseband microwave link. It is possible with the Warsanis 1401FM to create your 
own sound with an absolute control of peak modulation. You can vary your sound 
between unprocessed and heavily processed. With the Warsanis 1401FM you can 
give your station the punch, loudness and clarity you always wanted. The Warsanis 
1401FM does not only do a great job for CHR stations but also sounds perfectly for 
talk radio

 

and

 

AC music formats and even clasical.
