The Main Features of Midian Electronics VPU-12A Series Voice Inversion Scramblers

 

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–12A is compatible with Motorola's VPA, MX–Com's MXP–1080/1180 series, Transcrypt's SC20–400 and SC20–401, Selectone's ST–20, and more.
