Verbex VT-KP87 UHF Professional Wireless Microphone Metal Handheld For Conference Singing Stage Performance Microphone

Verbex VT-KP87 is a high-end UHF wireless microphone system designed for demanding environments like live stages, large conferences, and outdoor performances. Its standout feature is the True Diversity system combined with a four-antenna setup, which ensures a rock-solid signal even at extreme distances.

Exceptional Range: Most professional wireless mics struggle beyond 100 meters. The VT-KP87 boasts a massive 500m range in open environments and remains stable at 200m even in “harsh/rainy” conditions.

True Diversity & Anti-Interference: By using four antennas and a multi-level high-frequency filter, the receiver constantly switches to the strongest signal path. This prevents “dropouts” caused by dead spots in a room.

Protection Circuits: It features an “anti-switch impact” function. This is crucial because it prevents that loud “pop” when turning the mic on or off, which can otherwise blow out expensive PA speakers or amplifiers.

Efficient Power Management: The handheld units use a DC conversion boost circuit, allowing them to maintain high radiant power (16mW) while keeping power consumption low (110mA) to save battery life.
