RF Venue 4 Zone Antenna Combiner for Wireless Mics

Article number: 4ZONE
Availability: Ships from manufacturer

The 4 ZONE antenna combiner takes the complexity out of multi-zone wireless microphone projects. 4 ZONE combines together up to four separate pairs of diversity antenna connections for multi-purpose rooms, indoor-outdoor configurations, or main stages with secondary breakout rooms.

For fine tuning RF levels in each coverage area, 4 ZONE provides individual channel RF signal attenuation control down to -31dB in 1 dB steps. And for active antennas or in-line amplifiers, it features selectable 12V DC power to accommodate long cable runs.

With selectable ON/OFF inputs, 4 ZONE also allows for quick control of coverage zones for roaming microphone transmitters, so you can choose which zones are active as a live event or location sound project progresses, saving setup and breakdown time onsite.

When used in conjunction with up to four Diversity Fin Antennas and one or more DISTRO4 antenna distributors, 4 ZONE completes a turnkey package for any multi-zone wireless microphone project.
