Sennheiser Active antenna splitter (1x4), 694–1075 MHz, power supply included

The Sennheiser Active Antenna Splitter 1x4 is an active UHF antenna distribution solution designed for use with EW-D receivers. Operating across 694–1075 MHz, it distributes antenna signals to multiple receivers while providing DC power distribution. The system includes the NT 12-35 CS power supply and 8 BNC connection cables, making it a practical solution for expanding and managing professional EW-D wireless microphone setups.

The Sennheiser Active Antenna Splitter 1x4 is designed to simplify antenna distribution and receiver setups for Sennheiser EW-D wireless systems. Operating across the 694–1075 MHz UHF frequency range, the active splitter allows an antenna signal to be distributed across multiple receiver connections, helping create an organized and scalable multi-channel wireless system.

The splitter features a dual 1:4 configuration with DC voltage distribution, making it suitable for professional wireless installations where multiple EW-D receivers need to share antenna infrastructure. Its active design helps provide reliable signal distribution across the connected receiver system.

The unit is intended to work as part of the broader EW-D digital wireless ecosystem, which uses digital UHF transmission for enhanced range, reliability, and scalability. EW-D systems can be managed using the EW-D Smart Assist App via Bluetooth Low Energy, while automatic frequency scanning simplifies setup and helps establish reliable wireless connections.

EW-D technology provides a 134 dB audio input dynamic range, reducing the need for sensitivity adjustments while preserving audio detail. The system also eliminates intermodulation concerns, allowing channels to be arranged on an equidistant 600 kHz tuning grid. With 56 MHz of tuning bandwidth, up to 90 channels can be accommodated, while 2,240 selectable frequencies provide extensive frequency-selection flexibility.

The splitter package includes the required NT 12-35 CS power supply and eight BNC connection cables, providing the essential accessories for connecting and powering the antenna distribution system.
