RF Venue 4 ZONE
4 Zone Antenna Combiner


Designed to combine multiple pairs of diversity antennas used for wireless microphone receivers, the RF Venue 4 ZONE takes the complexity out of multi-zone wireless microphone projects. Combines together up to 4 separate pairs of diversity antenna connections for multi-purpose rooms, indoor-outdoor configurations, or main stages with secondary breakout rooms. It features RF input ON/OFF, along with 0 dB to -31 dB input attenuation, DC power for in-line ampliers or active antennas, and individual input signal ON/OFF control. It allows fine tuning of RF levels in each coverage area by providing individual channel RF signal attenuation control down to -31dB in 1 dB steps. For active antennas or in-line amplifiers, it features selectable 12V DC power to accommodate long cable runs. It has selectable ON/OFF inputs, offering quick control of coverage zones for roaming microphone transmitters, letting you choose which zones are active as a live event or location sound project progresses, saving onsite setup and breakdown time. Additionally, when it's used together with up to 4 Diversity Fin Antennas and one or more DISTRO4 antenna distributors (antennas and distributors sold separately), 4 ZONE completes a turnkey package that can be used for any multi-zone wireless microphone project.
