Sennheiser EW-D AB Integrated Antenna Amplifier (U)

Buy Sennheiser EW-D AB: Perfect Reception for Your Digital Wireless System

For absolutely reliable audio transmission in demanding environments, we recommend expanding your system with the Sennheiser EW-D AB Integrated Antenna Amplifier (U). Long cable runs between the antenna and receiver often lead to signal loss, which can cause risky dropouts during live use. This compact booster solves exactly this problem by stabilizing the signal strength and selectively filtering out unwanted interference frequencies. Secure the full performance of your wireless link now with minimal installation effort.

Your Benefits at a Glance

• Precise UHF Antenna Booster: Targeted amplification of the useful signal while suppressing interfering RF signals.
• Lossless Evolution Wireless Digital Accessory: Compensates for signal loss over long cable runs for maximum transmission reliability.
• Easy Installation via BNC Antenna Amplifier: Direct integration into existing cable routes without an external power supply at the device.
• Future-Proof Frequency-Selective Booster: Available in various versions for maximum flexibility in any UHF band.

Signal Stability and Range Without Compromise

A first-class audio experience begins with a stable reception. The integration of the Sennheiser EW-D AB ensures with a typical gain of 12 dB that your signal arrives powerfully at the receiver even after long cable runs. Since the amplifier operates frequency-selectively, only the relevant signals of your selected range are boosted – for example, between 823 and 865 MHz with the U version. All frequencies outside this window are effectively attenuated, which massively reduces the risk of interference from external radio sources. Thanks to the robust BNC connectors, the booster can be securely positioned in any rack. This creates the basis for a disturbance-free performance, no matter how large the stage is.

Intelligent Power Supply and Easy Scaling

The handling of the system is consistently trimmed for efficiency. The EW-D AB draws its power directly via the antenna cable from the EW-D ASA splitter, so you do not need additional power outlets at the installation site. An integrated green LED gives you immediate assurance that the device is correctly powered. Particularly advantageous for complex setups is the DC pass-through function. This allows you to operate up to two antenna amplifiers in series on a single cable run to safely bridge even extremely long distances. In combination with the Smart Assist App, you also maintain full control over your entire setup.

Maximum Flexibility Through Customizable Frequency Ranges

Every production environment has different requirements for the radio frequencies used. To ensure optimal performance, this antenna amplifier is available in various versions that are precisely matched to the respective EW-D receivers. While model U covers the range from 823 to 865 MHz, versions Q, R, S, and Y are also available for other requirements. This specification is crucial, as a broadband amplifier would often also amplify unwanted noise. By choosing the right version, you ensure that your system operates exclusively in the intended window and delivers the best possible signal quality.

Our Conclusion: Why the Sennheiser EW-D AB is the Ideal Choice for Your Wireless Link

The Sennheiser EW-D AB offers you the necessary security for professional wireless applications by eliminating signal loss and improving the RF selectivity of your system. With technical specifications such as the 12 dB gain and the practical DC pass-through, it is an indispensable tool for musicians and technicians who rely on absolute fail-safe operation.
