Sennheiser AD 9000 Directional Active Intelligent Receiving Antenna for Digital 9000 Series Systems (A1-A8: 470 to 638 MHz)

Introducing the Sennheiser AD 9000 Receiving Antenna
Elevate your audio broadcast capabilities with the Sennheiser AD 9000, a state-of-the-art directional, active, and intelligent receiving antenna designed specifically for the Digital 9000 Series EM 9046 receiver. This advanced antenna includes the integrated AB 9000 booster, which enhances its performance by effectively increasing the reception quality and distance, ensuring your broadcasts are crystal clear and free of interference.

Optimized Signal Reception with Selective Filtering
The AD 9000 is equipped with eight highly selective bandpass filters, each designed to pass frequencies within a precise 24 MHz frequency window while blocking those outside this range. This selective filtering is critical in maintaining a clean signal, free from unwanted frequencies and noise, enhancing the overall quality of the audio output.

Remote Frequency Selection for Enhanced Flexibility
Flexibility is at the core of the AD 9000's design. The frequency window for each of the bandpass filters can be remotely selected from the EM 9046 receiver, allowing for seamless adjustments and optimal performance across various locations and scenarios. This feature ensures that the antenna can adapt to different broadcasting conditions without manual reconfiguration.

Superior Amplification and Intermodulation Resistance
The built-in linear RF amplifier in the AD 9000 not only compensates for up to 14 dB of cable loss but also offers exceptional resistance to intermodulation. This ensures that the antenna maintains a high-quality signal even in environments with multiple competing signals, making it ideal for large-scale events and complex broadcast setups.

Automatic Gain Adjustment for Consistent Performance
One of the standout features of the AD 9000 is its ability to work in concert with the EM 9046 receiver to automatically monitor and adjust the gain based on detected RF cable loss. This intelligent functionality allows for consistent, high-quality performance without the need for constant manual tuning.
