Programming the Audio Levels:
After determining the audio levels at the audio hookup points, it is necessary to
program the scrambler for 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. The following table shows Midian’s
recommended levels for the VS-1200/VS-1100/VS-110 at 60% modulation:
