In the heat of a performance, every note and cue counts—and wireless in-ear monitor systems are the backbone of that precision. By keeping performers in sync, IEMs transform individual contributions into a cohesive, polished show. However, as more IEMs are added, issues like dropouts and interference become harder to control, putting this harmony at risk. The root cause often lies in the overloaded antenna farms, where numerous antennas and signals collide, generating cross-polarization fades, intermodulation distortion, and excess noise. This is where our new PAS-227X antenna combiner steps in.

Understanding the Antenna Combiner

Before we delve into the details, let’s take a brief look at how an antenna combiner works. The process begins with multiple RF signals from IEM transmitters being sent via coaxial cables to the antenna combiner. The combiner merges these signals and directs them to a single antenna, which transmits the combined mixes across multiple frequencies. By utilizing a paddle antenna, you can position it flexibly in an elevated or unobstructed location to achieve better reception and minimize interference. Finally, beltpack receivers pick up these RF signals, convert them back into audio, and deliver clear and synchronized sound directly to the performers' in-ear monitors, providing reliable monitoring during performances.

Designed for busy stages and complex setups, the antenna combiner ensures seamless signal integration, cleaning up the RF environment and boosting signal transmission to optimize your IEM setup.

Move Past the Chaos

No longer will you be burdened by the mess of closely-spaced antennas—the PAS-227X antenna combiner offers you a more streamlined, organized setup. Equipped with four antenna inputs, the combiner supports input from up to four in-ear monitor transmitters signals, merging them into one unified, powerful antenna output. This efficient management reduces deadspots arosed from cross-polarization fades and interference from intermodulation distortion, resulting in extended coverage and enhanced wireless reliability.

Ready for Any Stage

Take full control of your signal with the 16-level gain control. With a maximum boost of +6dB, this feature gives you the flexibility to adapt to any environment. In larger venues, simply increase the gain to offset signal loss; In crowded RF areas, reduce the gain to avoid signal overload. No matter the space, fine-tune your gain to achieve consistent performance every time.

Works Across the Board

Compatibility is never an issue—this universal solution fits effortlessly with most IEM systems. The PAS-227X works seamlessly with nearly all wireless IEM brands within the 450-970 MHz frequency range.

Setup with Ease

Embrace ultimate convenience through every thoughtful detail. Compact half-rack design helps conserve valuable rack space to configure more devices. Removable feets allow for quick rack installation. Built-in adapter cord tie-off keeps cable neat and tidy. Plus, the RF LED indicator on the front panel provides real-time monitoring of the signal input from each IEM transmitter.
