Shure PA411

Overview

The Shure PA411 is a wideband antenna combiner designed to simplify the setup and operation of multiple PSM300 in-ear monitor transmitters. It consolidates RF signals and DC power for up to four transmitters into a single unit, reducing cable clutter and making rack setups cleaner and more efficient. Operating across a broad frequency range of 470 to 865 MHz, it supports all PSM300 frequency bands, allowing easy frequency switching or transmitter additions without hardware changes.

Key features

• Distributes RF signal and 12 V DC power to four PSM300 transmitters, eliminating the need for multiple antennas and power supplies.
• Wide frequency coverage from 470 to 865 MHz ensures compatibility with every PSM300 band for flexible operation.
• Single 15 V power input supplies up to 1.4 A total current across all four ports, powering all connected transmitters directly.
• Front-panel LEDs provide clear indication of RF signal presence and alert to any channel overload, enabling quick monitoring.
• 40 dB of reverse isolation prevents signal leakage between transmitters, reducing interference and maintaining signal integrity.
• Compact half-rack chassis fits easily into portable or permanent racks, with included rack ears, whip antenna, BNC connectors, and power supply for immediate use.

Connectivity and compatibility

The PA411 connects to up to four Shure PSM300 transmitters via rear-panel BNC ports, delivering both RF and DC power through the same connections. This integration reduces the number of cables and power supplies needed, streamlining your audio rack setup. The included quarter-wave whip antenna ensures reliable signal transmission, and the unit’s wide frequency range supports all PSM300 bands, making it adaptable to various wireless environments.

Installation and setup

Designed for quick deployment, the PA411’s half-rack size fits standard racks and portable fly cases. Rack ears and all necessary hardware come included, so you can mount the unit without additional accessories. The front power switch allows easy control without accessing the rear panel, and status LEDs provide immediate feedback on signal and power conditions, helping you maintain optimal performance during events or broadcasts.

Ideal uses and environments

This antenna combiner is well suited to live sound engineers and audio professionals working in clubs, theaters, houses of worship, and corporate event venues. It supports setups where multiple PSM300 transmitters are used simultaneously, offering a neat and reliable solution that reduces setup time and potential interference. Its robust design and comprehensive features make it a strong choice for both touring and fixed installations.

We act solely as a reseller. Any product warranty is provided and administered by the manufacturer, not by our store. That means eligibility, coverage, and outcomes are determined by the manufacturer’s policy for each brand and model. Before purchasing, we recommend reviewing the warranty terms on the manufacturer’s website or in the product documentation to confirm what is covered and for how long.

If you need warranty service, please file the claim directly with the manufacturer. They may require proof of purchase, the product serial number, original packaging, photos, or basic troubleshooting. Some brands ask you to register the product or obtain a case number before shipping it for repair or replacement. We don’t submit or approve claims, but we can point you to the correct support links and contact details.

Keep your invoice and packaging in a safe place, and report any functional issues to the manufacturer as soon as they appear. If you’re unsure whether a problem is covered, the manufacturer’s support team can confirm next steps and timelines. While we cannot intervene in decisions or outcomes, we’re happy to provide purchase documentation or guidance so you can move through the warranty process smoothly.
