New Product of UD90 Distributor & A9000 Antenna
New Product Launch: KEV UD90 RF Distributor & A9000 High-Performance Antenna Amplifier
KEV is proud to unveil its latest professional RF solutions: the UD90 Antenna Distributor and A9000 High-Gain Antenna Amplifier, engineered to redefine signal stability and operational precision for wireless microphone systems in demanding professional environments. Built as an upgraded successor to the UD80, the UD90 expands channel capacity to 18 total outputs (2×9 channels), delivering expanded connectivity for large-scale multi-channel wireless setups. It features a vibrant color TFT high-definition display that delivers real-time, crystal-clear status readouts, simplifying system monitoring and on-site operation for audio technicians and engineers.
Paired exclusively with the UD90, the A9000 stands as KEV‘s flagship antenna amplifier, setting a new benchmark for signal performance in the professional audio market. While standard industry antennas offer a limited gain range of -6dB to +12dB, the A9000 delivers an expanded -12dB to +18dB gain spectrum with precise 1dB incremental adjustment, a level of control unmatched by competing products. This ultra-fine tuning eliminates two critical pain points: over-amplified signals that introduce hum, static, and background noise, and underpowered signals that reduce transmission range and cause disruptive frequency dropouts or audio cutouts.
Designed for versatility, the UD90 and A9000 combo excels across high-demand professional scenarios, including large concert venues, broadcast studios, corporate convention centers, theaters, houses of worship, touring productions, and multi-stage live events. Both units operate across a wide UHF frequency band of 450-970MHz, with a 50-ohm impedance for universal system compatibility. The A9000 features a 0°-230° primary radiation range, touch-button controls, and a robust third-order intercept point of +48dBm for exceptional interference resistance. The UD90 offers 31-level adjustable gain from -24dB to +6dB, tight gain flatness of ±1dB, and stable DC power output to support long-term, uninterrupted operation.
Engineered for reliability, precision, and scalability, the UD90 and A9000 deliver professional-grade RF performance that adapts to the most challenging acoustic and electromagnetic environments, ensuring consistent, clear wireless audio for critical live and installed applications.
