Sennheiser EW-D ASA (Q-R-S) — Antenna Splitter Amplifier
EW-D ASA Overview
The Sennheiser EW-D ASA is an antenna splitter amplifier built to expand the antenna infrastructure of EW-D series wireless deployments. Designed for installations where multiple receivers must share a common antenna pair, the EW-D ASA distributes RF signal across connected receivers while maintaining signal integrity. It is compatible with the Q, R, and S frequency band variants of the EW-D platform, making it a flexible solution for multi-channel wireless system builds. Audio engineers, system integrators, houses of worship, and touring companies will find it an essential component for scalable, rack-based wireless setups.
The EW-D ASA supports clean RF distribution in environments where antenna placement must be centralized, reducing cable runs and simplifying antenna management across larger channel counts.
Key Features
