Rent the Shure PA421B in Ibiza and streamline your in-ear monitoring system with this professional-grade antenna combiner. Ideal for stages, festivals, and corporate events, it allows you to combine up to four PSM transmitters into a single RF output—simplifying your wireless rack and improving system reliability.

The PA421B supports PSM300, PSM900, and PSM1000 transmitters. It includes four front-panel BNC inputs for transmitter RF signals and one rear BNC output that feeds a single antenna. This reduces intermodulation, improves RF efficiency, and ensures clean signal distribution.

It also features four DC power outputs, eliminating the need for multiple external power supplies in your rack. Each power output delivers regulated 12 V DC, supporting up to 800 mA per port—sufficient for powering four transmitters simultaneously.

With broadband operation across 470–865 MHz, the PA421B is compatible with most frequency bands used in professional setups. Its rugged 1U metal chassis is perfect for touring racks and mobile setups.

Whether you’re deploying a multi-channel IEM rig or just want to clean up your wireless signal path, the Shure PA421B antenna combiner improves performance, reduces clutter, and ensures reliable monitoring.

Rent the Shure PA421B in Ibiza today with White Sound Ibiza and upgrade your wireless infrastructure with smart RF management.
