Frequently Asked Questions

It's rated for up to 30mW per transmitter, exceeding the power requirements of most PSM systems, but pushing beyond that could introduce intermodulation.
It’s compatible with any antenna having a BNC connector, but optimal performance is achieved when using Shure-recommended antennas designed for PSM systems.
It’s largely passive, utilizing precision impedance matching to minimize signal loss, although a small amount of gain may be present depending on the connected antennas.
