Sennheiser EW-D ASA (Q-R-S) Overview

The rugged, all-metal Sennheiser EW-D ASA is a 4-way active antenna splitter that delivers diversity wireless signal distribution for up to four EW-D EM wireless receivers. It also provides DC power to the four receivers, for less clutter in your rack. The unit covers the Q, R, and S frequency ranges, from 470 to 694 MHz.

The EW-D ASA receives up to four wireless microphone signals through a single pair of antennas, split and amplifies these signals, and send each signal to their respective receiver via the included BNC cables.

You can either use a pair of 1/4 wave antenna (provided with one of the receivers) or upgrade to longer, 1/2-wave dipole antennas (available separately) for added range and reliability.

Adding the ADP UHF passive/directional remote antennas (available separately) to your system enables you to position the antennas closer to your transmitters and orient them for maximum coverage, achieving professional-quality RF signal reliability with virtually no dropouts.

Included is the NT 12-35 CS universal power supply with EU, UK and US adapters.
