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.
Midian's VPU-12 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 others.
Applications
Midian's voice scramblers are ideal for government, public
safety, fleets (i.e. taxi, towing, fishing), and private use.
Installation
Midian's The VPU-12 does not require any modifications to the repeater and has no effect on the
range of the radio. Midian's voice scramblers are
well known in the industry as offering the best audio quality and speaker
recognition.
