True Diversity is a common wireless microphone term. It refers to a more advanced form of a diversity receiver as a true diversity system contains a radio receiver that actually has two independent receiver sections, each with its own antenna (rather than a single receiver with one or two antennas), to pick up the transmission from a wireless microphone.

The HR-31S UHF single channel true diversity wireless mic system consists of a handheld vocal microphone, true diversity rack mountable receiver (includes 2 detachable antennas), body-pack transmitter, and you can selective assemble wireless digital software for real time monitoring. It can automatically determine the correct frequency for setup, minimize errors and increase mic-to-mic sound continuity. The HR-31S UHF true diversity wireless mic system is intended for large-scaled stage performances. It has 1280 selectable UHF frequencies and true diversity reception, and guarantees incredible audio quality and reliable performance for artists, broadcasters and other demanding audio environments.
