VPU-15

High Level Voice Inversion Scrambler

 

  • Offers Advanced Signaling Features
  • Up to 4 Programmable Inversion Frequencies
  • Automatic Detection of Scrambled vs. Clear Conversations
 
 
 
 
Midian's VPU Series of inversion voice scramblers protect your voice communications against casual listeners. By mixing the frequency of the voice with an inversion tone in a balanced modulator, sum and difference frequencies are created. A low-pass filter eliminates the sum and the difference is transmitted as "inverted voice". The "inverted voice" undergoes an identical process on the receiving end that reconstructs the voice. Midian's VPU series voice scramblers are available in simplex, half-duplex, or full-duplex operation.
