This dual-function design simplifies IEM rack wiring by combining both antenna consolidation and power distribution into one device, reducing the total component count and cable complexity in the wireless rack.\u003c\/p\u003e \u003cp\u003eThe AC 41-US is supplied as a complete kit with one NT 3-1-US power supply and four BNC cables, providing everything needed to connect four IEM transmitters to a single shared antenna. Active combining ensures that each transmitter's output is isolated from the others, preventing intermodulation and maintaining clean RF performance across all four channels.\u003c\/p\u003e \u003ch2\u003eKey Features\u003c\/h2\u003e \u003cul\u003e \u003cli\u003e4:1 active antenna combining for up to four IEM transmitters\u003c\/li\u003e \u003cli\u003eDC power distribution to connected transmitters via the combiner\u003c\/li\u003e \u003cli\u003eIncludes NT 3-1-US power supply and four BNC cables\u003c\/li\u003e \u003cli\u003eActive isolation between combined channels\u003c\/li\u003e \u003cli\u003eBNC connections for all inputs and combined output\u003c\/li\u003e \u003cli\u003eUS-version power supply for North American deployments\u003c\/li\u003e \u003c\/ul\u003e \u003ch2\u003eProfessional Applications\u003c\/h2\u003e\u003cp\u003eCommonly deployed in church, house of worship, and professional AV environments.\u003c\/p\u003e \u003cul\u003e \u003cli\u003eIEM transmitter racks for touring and event productions\u003c\/li\u003e \u003cli\u003eWorship and theater IEM systems with multiple performers\u003c\/li\u003e \u003cli\u003eBroadcast IFB and cue-feed transmitter consolidation\u003c\/li\u003e \u003cli\u003eCompact IEM deployments where space and cable count are limited\u003c\/li\u003e \u003c\/ul\u003e \u003ch2\u003eFrequently Asked Questions\u003c\/h2\u003e \u003ch3\u003eHow many transmitters can the AC 41-US support?\u003c\/h3\u003e \u003cp\u003eThe AC 41-US combines up to four transmitter outputs into one antenna.
