Sennheiser EW-D ASA Active Antenna Splitter (Dual 1:4)

The Sennheiser EW-D ASA Active Antenna Splitter (Dual 1:4) is a cornerstone for professional wireless setups, engineered to deliver reliable, high-quality RF distribution across multiple EW-D receivers. Designed for vocalists, presenters, and musicians who demand seamless performance in demanding environments, this advanced antenna splitter simplifies large-scale wireless configurations while safeguarding signal integrity. When paired with the ew-d smart assist app, technicians gain powerful, real-time control and diagnostics—empowering fast, proactive adjustments on stage, in rehearsals, or during a high-stakes broadcast. In short, the EW-D ASA helps you achieve consistent coverage, reduced dropouts, and a more predictable RF landscape so performers can focus on their craft rather than on wireless troubleshooting.

• Dual 1:4 active splitter design: Two independent, high-efficiency RF splitters feed four receivers each from a single or dual antenna setup. This architecture minimizes cumulative insertion loss, preserves signal quality across all connections, and mitigates issues like phase distortion and intermodulation that can plague multi-channel wireless environments. With eight possible receiver connections, the EW-D ASA enables expansive stage layouts, orchestras, choirs, and live venues to cover wide performance footprints without sacrificing audio fidelity.
• Seamless integration with the ew-d smart assist app: Manage your wireless ecosystem from a single, intuitive interface. The app provides real-time signal maps, spectrum awareness, and proactive diagnostics that help you spot interference before it affects your performance. Quick pairing, channel status checks, antenna level adjustments, and firmware updates can all be performed remotely, reducing on-stage setup time and enabling rapid reconfigurations between songs, scenes, or acts.
• UHF-range performance for extended coverage and reduced interference: Optimized for the UHF spectrum used by Sennheiser EW-D devices, the ASA enhances range and penetration through venue obstacles, while minimizing interference from other RF systems. This results in more stable reception, fewer dropouts, and improved reliability in RF-dense environments such as stadiums, theaters, and busy conference centers. The robust RF design supports consistent audio timing and synchronization across connected receivers—crucial for multi-channel performances and broadcast scenarios.
• Rugged, rack-ready construction for professional use: The ASA is built to withstand the rigors of touring and permanent installations. Its compact, 19-inch rack-mountable chassis features sturdy connectors, defined labeling, and efficient heat management to maintain performance during long shows. The modular design enables flexible antenna strategies, allowing venues to implement diverse coverage plans—from centralized balconies to distributed stage-side booths—without compromising signal integrity.
• Premium sound quality and dependable reliability: By preserving RF energy with low loss and stable gain across all outputs, the EW-D ASA supports consistent audio quality across the EW-D ecosystem. Audiences hear clear, natural sound with minimal coloration or noise, while technicians benefit from predictable behavior under real-world conditions. Built for speed and reliability, this antenna splitter helps ensure that even complex multi-channel performances meet professional-grade standards, from rehearsal to curtain call.

How to install Sennheiser EW-D ASA Active Antenna Splitter (Dual 1:4)

• Plan your venue layout and antenna strategy. Identify central antenna locations that maximize line-of-sight to the performers, then determine how the two 1:4 outputs will feed your EW-D receivers. If possible, position antennas to minimize RF obstacles and reflections, and route coax lines with care to avoid signal degradation.
• Prepare the rack and power foundation. Install the EW-D ASA in a standard 19" equipment rack, ensuring proper ventilation and access to a reliable power source. Verify that the power supply and any accessories conform to the included specifications, and mount cables neatly to prevent strain on connectors during transport.
• Connect antennas to the ASA inputs. Attach high-quality coax cables from your antennas to the input ports on the splitter. Confirm connector types (e.g., BNC or N-type) and secure each connection to reduce RF loss. If using multiple antennas, balance the inputs to achieve even coverage across the venue.
• Distribute RF to receivers. Run eight output connections (four per channel) to the EW-D receivers in your system, labeling each cable for quick identification during setup and rehearsals. Maintain consistent cable routing and shielding to minimize interference from nearby power lines, lighting rigs, or other RF devices.
• Power up, configure, and validate using the ew-d smart assist app. Power on the ASA, then open the app to monitor RF activity, check antenna levels, and ensure all connected receivers are tracking correctly. Perform a live test with vocalists or instrumentalists to assess dropouts, latency, and overall sound quality, adjusting antenna gain and channel assignments as needed for optimal performance.
