The Sennheiser EW-D ASA (Q-R-S) is an active antenna splitter designed for setting up an antenna distribution in multi-channel systems for the EW-D series. It supplies up to four diversity receivers with the received radio signal from two antennas.

The antenna splitter powers four receivers and two antenna amplifiers per antenna input simultaneously through its BNC sockets. The appropriate power supply NT 12-35 CS is included for powering the Sennheiser EW-D ASA. Also included are 8 BNC connection cables.

Setting new standards

Evolution Wireless Digital breaks current boundaries with a greater dynamic range than all other systems currently available. In everyday use, the system automatically searches for the best transmission frequency within seconds and allows for up to 90 additional channels thanks to a 56 MHz switching bandwidth. It is easy to see: the wireless system is in a class of its own.

Equidistant spacing – easier than it sounds

Evolution Wireless Digital features an equidistant frequency grid, which was previously only found in our flagship systems like Digital 6000 and Digital 9000. High-quality components with extraordinary linearity eliminate intermodulations between EW-D transmitters, allowing for frequency allocation every 600 kHz side by side. This simplifies coordination for both beginners and experienced users alike. Additionally, it contributes to the scalability of the system and the high channel limit.
