No reviews

Sale price$2,467.30


The PA421B Antenna Combiner from Shure combines up to four PSM transmitters to a single antenna set. It can be used when multiple wireless systems are required for monitoring in sound reinforcement applications.

The PA421B reduces rack clutter, optimizes RF management, and provides DC power to compatible IEM transmitters. LED indicators for signal presence and signal overload provide four input LED signals (green when active, off inactive). Also, a very quiet, temperature-sensitive fan keeps the unit cool.

*The TAA-compliant models are made-to-order with a typical delivery time of 2 to 4 weeks. The additional cost of producing separate model variations is reflected in higher pricing compared to standard SKUs.
