Programming the Audio Levels: 

 

After determining the audio levels at the audio hookup points, it will be necessary to program the scrambler to 
match these levels. In the programming software, there is a slider control on the Audio Levels Screen for each of 
the of four audio hookup points. Locate the column that corresponds to the modulation and units of measurement 
for each of the audio hookup points. Adjust the slider bar such that the value appearing in the appropriate column 
matches what was measured as closely as possible. Midian recommends the following values based on 60% 
modulation: 
 
The following table shows Midian’s recommended levels in mVpp for the VS-1200, VS-110 & VS-1100 at 60% 
modulation for tested models of radios:
