Sennheiser ASA 214 Splitter – Active Antenna Splitter for EW Series

The ASA 214 active antenna splitter is a professional-grade distribution hub designed for Sennheiser EW wireless systems. Constructed with a robust full metal housing, it delivers reliable RF distribution to multiple receivers from just two antennas, making it ideal for stages, broadcast studios, and venues where pristine wireless audio is non-negotiable. Included with the unit are 8 BNC cables, ensuring you have ample wiring for quick setup and flexible placement around the rig. The UHF version ships with the NT 1-1 power supply and regional adapters (EU, UK, and US), while the ASA 214-1G8 variant includes the NT 1-1 power supply, giving you a ready-to-use solution out of the box.

• Reliable multi-receiver distribution: The ASA 214 is engineered to feed up to four EW receivers from a pair of antennas, simplifying RF planning on busy stages and ensuring consistent performance across the setup. This capability is essential when deploying multiple handheld or bodypack units in live environments, where RF congestion can otherwise degrade audio quality.
• Two-input, four-output design: With two antenna inputs and four RF outputs, you gain flexible receiver placement without sacrificing signal integrity. The design minimizes coaxial runs and reduces RF drop, helping you maintain strong, clear reception even as stage layouts change or additional receivers are added for larger productions.
• Rugged, professional-grade build: A full metal housing provides exceptional durability for touring, broadcast, and venue contexts. The ASA 214 is built to withstand the rigors of live performances, providing steady performance in demanding environments where dust, vibrations, and handling are common.
• Power options built in: The UHF version includes the NT 1-1 power supply with adapters for EU, UK, and US regions, ensuring compatibility with common power layouts worldwide. The ASA 214-1G8 variant also includes the NT 1-1 power supply, offering a turnkey solution for installers and technicians who require reliable, ready-to-use power connectivity.
• Seamless EW integration: Specifically designed to complement Sennheiser EW wireless systems, the ASA 214 enhances RF management, simplifies setup, and helps maximize system performance. It integrates smoothly with existing EW components, enabling quick configuration changes during rehearsals and performances.
