The Sennheiser Active Zone Antenna Combiner 2×4:1 (1U, 19”)
The Sennheiser Active Zone Antenna Combiner 2×4:1 (ACA 3) is a professional active RF distribution unit designed for complex wireless microphone systems. It allows independent control of multiple antenna zones, ensuring flexible, reliable signal coverage across large venues such as broadcast productions, sports events, and multi-room installations.
This high-performance active antenna combiner enables the combination and management of up to four antenna zones per system, providing flexible RF distribution for large-scale and complex environments.
Ideal for professional broadcast productions, live sports coverage, television outside broadcasts, and multi-room event venues, the system allows antennas to be distributed across different physical areas. Each antenna input can be individually activated or deactivated, and its integrated power switching allows control over antenna amplifiers for optimized signal management.
Operating across a wide 470–798 MHz frequency range, the ACA 3 supports both analog and digital Sennheiser wireless microphone systems. Its active design ensures stable RF performance and consistent signal distribution even in demanding setups.
The unit features front-panel status indicators for active inputs and power monitoring, allowing quick system overview and diagnostics during operation. Housed in a standard 19” rack-mount 1U chassis, it integrates easily into professional audio racks and broadcast systems.
