The Lectrosonics PF25 is a passive filter that's compatible with Venue series receivers and UMC16B multicouplers operating in frequency block 21. It's a simple BNC adapter that you insert into a coaxial line between the antenna and the receiver or multicoupler. Just like the front-end filters in your system, the PF25 will add an extra layer of protection helping to reduce interference and intermodulation. If you're using a remote antenna amplifier, the PF25 is designed to bidirectionally pass phantom power to operate the device.
Whether you're using just a single receiver or multicoupler, or a more complex set up with an antenna distribution system, you can benefit from using a PF25 passive filter.
