Sennheiser EW-D AB (Q) Antenna Booster 470 - 550 MHz

The Sennheiser EW-D AB Inline Antenna Booster is a high-quality, frequency-selective antenna booster that gets inserted between a remote antenna and an EW-D ASA antenna splitter.
It delivers a 12 dB boost to compensate for RF signal loss when running long coaxial antenna cables, helping to significantly improve the wireless performance of your EW-D series receiver.

The frequency selectivity of the EW-D AB ensures that all RF signals within the specified R: 470 to 550 MHz frequency range are amplified while RF signals with frequencies outside of the specified range are attenuated.

The EW-D AB receives DC power from the EW-D ASA antenna splitter.
A DC pass-through capability enables you to connect up to two EW-D AB per antenna cable line (DC-coupled).
A green LED indicates that the unit is receiving sufficient DC power.

Raising the bar
Evolution Wireless Digital breaks the boundaries by providing more dynamic range than any wireless system currently on the market.
Automatically securing the most reliable signal in a matter of seconds and scalable up 90 channels thanks to 56 MHz of tuning bandwidth, it's easy to see why this wireless system is in a class of its own.

Equidistant Spacing - simpler than it sounds
Evolution Wireless Digital features an equidistant tuning grid previously only found in our flagship Digital 6000 and Digital 9000 wireless systems.
Quality components with exceptional linearity eliminate intermodulation between EW-D transmitters, allowing frequencies to be equally spaced every 600 kHz alongside each other.
This simplifies frequency coordination for wireless beginners and seasoned professionals alike, and also contributes to the system's scalability and impressively high channel count.

An engineer in your pocket
The power of Bluetooth Low Energy puts full control right in the palm of your hand with the Sennheiser Smart Assist app.
Take advantage of a remarkably fast automated setup, mobile access to every system setting and the added benefit of remote monitoring, all from the convenience of your Android or iOS device. Save time, save energy and perform with confidence.
