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

The Sennheiser EW-D ASA Active Antenna Splitter is a purpose-built control hub for professional wireless setups, designed to expand your EW-D ecosystem with reliable, road-ready RF distribution. Perfect for live performances, studios, houses of worship, and venue installations, this dual 1:4 splitter delivers consistent antenna coverage to multiple receivers while preserving signal integrity. Built to support a seamless workflow, it integrates smoothly with the ew-d smart assist app for quick pairing, monitoring, and management, helping you keep everything aligned from setup to showtime. With robust UHF digital transmission, this accessory helps you push range, reliability, and intelligible audio to the forefront of your performance, so you can focus on your performance instead of RF juggling.

• Dual 1:4 active antenna distribution: Two RF antenna inputs feed four receiver outputs each, enabling you to scale from a small setup to a full-on multi-receiver rig without sacrificing signal quality or headroom. This configuration reduces the need for multiple passive splitters and minimizes loss, delivering consistent reception across the stage or venue.
• High-performance RF management for live sound: Engineered to maintain strong RF signal integrity, the ASA distributes antenna signals with excellent isolation between outputs, mitigating crosstalk and interference. The result is fewer dropouts, steadier gain across channels, and dependable performance during demanding live events.
• Optimized for EW-D digital wireless in the UHF spectrum: The splitter leverages the benefits of digital transmission in the UHF range—enhanced range, better interference handling, and robust performance in busy RF environments. It ensures your EW-D receivers stay synchronized and ready to capture every note, cue, and spoken word with clarity.
• Effortless pairing and management via the ew-d smart assist app: This accessory mirrors Sennheiser’s commitment to a streamlined workflow. The EW-D ASA works in concert with the app to simplify device pairing, monitoring, and management, so you can configure channels, check RF health, and troubleshoot from a single intuitive interface.
• Rugged, professional build for touring and installs: Encased in a durable chassis designed for road use, the ASA is built to withstand the rigors of live touring, theater productions, and installation environments. Its compact footprint fits neatly into racks or on a desktop, keeping your RF infrastructure organized and accessible.

how to install Sennheiser EW-D ASA Active Antenna Splitter

Setting up the EW-D ASA is a straightforward process that helps you establish a robust RF backbone for your EW-D receivers. Follow these steps to integrate the dual 1:4 active antenna splitter into your system and maximize coverage across your venue.

• Plan your layout: Determine the locations of your two main RF antennas and the eight receiver outputs. Place the splitter in a central, accessible spot with solid airflow and away from potential RF blockers or sources of interference.
• Mount and connect: Install the ASA in a rack or on a stable stand. Connect your two external antennas to the two input connectors on the unit. Ensure the connectors are tightened securely to avoid signal loss.
• Connect receivers: Attach up to four EW-D receivers to each of the four outputs per channel, using appropriate RF cables. Maintain cable management to prevent accidental disconnections and minimize EMI exposure.
• Power up: Connect the external DC power supply specified for the ASA and power on the unit. Allow a brief warm-up period for stable operation and for the power rails to settle.
• Pair and configure with the app: Open the ew-d smart assist app and follow the prompts to pair the ASA with your EW-D receivers. Use the app to confirm signal integrity, assign receivers to specific outputs, and monitor RF health across channels.
• Test and optimize: Run a quick on-site test with vocalists, instrumentalists, or click tracks. Observe the RF meters in the app, listen for any dropouts, and adjust antenna placement if needed to optimize coverage and minimize interference.

Frequently asked questions

• Q: What is the primary purpose of the EW-D ASA Active Antenna Splitter? A: It provides active distribution of antenna signals to multiple EW-D receivers (Dual 1:4), expanding coverage while preserving signal integrity for reliable wireless operation.
• Q: How many receivers can be connected to the ASA? A: Up to eight receivers can be connected—four outputs per channel across two input channels—depending on your configuration and RF environment.
• Q: Does this splitter require a separate power supply? A: Yes, the ASA uses an external DC power supply to operate the active distribution circuit and maintain consistent output levels.
• Q: Can I use the EW-D ASA with non-Sennheiser wireless systems? A: The ASA is designed to work within the EW-D ecosystem to optimize performance. While it may physically connect to other devices, optimal results are achieved when used with EW-D components.
• Q: How does the app assist with installation and operation? A: The ew-d smart assist app guides pairing, monitors RF health, provides signaling status, and helps manage receiver configurations, making it easier to keep the system in peak form during rehearsals and performances.
• Q: Is the ASA suitable for touring and venue installs? A: Yes. Its rugged build, compact form factor, and rack-mounting compatibility make it ideal for touring rigs and fixed installations that require scalable RF distribution and reliable performance across multiple receivers.
