Introduction
The VR3 receiver provided with the VHF Series wireless system utilizes non-diversity
technology, incorporating a single antenna for ease of use and minimal cost. The VR3TD
receiver provided with the VHF TD Series system utilizes a patented technological
breakthrough called “Microprocessor True Diversity,” whereby a single chassis houses
two antennas (called “Antenna A” and “Antenna B”) and a receiver circuit. A built-in
computer chip continuously scans RF signals from the two antennas and determines
which one has the clearest and strongest reception, automatically (and silently) switching
that signal to the receiver. This allows you to maintain the wireless communication link
over a much broader area range than would be allowed by a receiver utilizing a single
antenna and also virtually eliminates multipath dropouts, interference and phase
cancellation problems. In addition, special sample-and-hold linking circuitry ensures that
correct phase correlation is maintained at all times, with no noise or pops during antenna
switching. The result is performance which exceeds that of conventional antenna true
diversity systems and the highest quality audio fidelity available in any wireless system.
Finally, the provision of Signetics® noise reduction produces crystal-clear sound with
minimized background noise and hiss.
