DESCRIPTION


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.

 

APPLICATIONS


Midian's voice scramblers are ideal for government, public safety, fleets (i.e. taxi, towing, fishing), and private use.

 

INSTALLATION


Midian's VPU series voice scramblers can be fitted into most radios. Midian currently offers plug-in inversion scramblers for many current OEM radios. Midian's voice scramblers are well know in the industry as offering the best audio quality and speaker recognition.
