About BSS AEC Card

It's time to elevate your audio experience with the Soundweb London Acoustic Echo Cancellation (AEC) Input Cards. Specifically designed to seamlessly integrate with the Soundweb London BLU-800, BLU-805, BLU-806, BLU-320, BLU-325, BLU-326, BLU-160, and BLU-120 network audio systems, these AEC Input Cards are your solution to eliminating acoustic echo. This common issue arises during conference applications when sound from a loudspeaker enters a microphone within the same room.

Much like the Soundweb London Analog Input Cards, these AEC Input Cards come equipped with Phantom Power, which can be conveniently configured per channel. They also offer software-controlled analog gain, adjustable in 6dB increments from 0dB to 48dB, providing you with precise control over your audio output.

The Soundweb London AEC Input Cards feature four independent channels of AEC, each of which can be freely configured via software. This flexibility allows users to tailor their audio setup to multiple spaces using just a single device. The cards also come with individual AEC references, further enhancing their adaptability.

To ensure optimal audio quality, these cards come with Automatic Gain Control (AGC). This feature maintains the inputs of the microphones at the ideal level, ensuring a consistent and high-quality audio experience.

Noise Cancellation (NC) technology is also incorporated into these cards. This feature effectively removes steady-state noise, such as that produced by a projector fan or air conditioning unit, from the signal path. This prevents such noise from being amplified and interfering with your audio experience.

The Soundweb London AEC Input Cards also feature Non-Linear Processing (NLP), which dynamically adjusts to minimize echo caused by under or over-cancellation.

In addition to these features, the AEC Input Cards also offer a direct microphone feed for local sound reinforcement. This allows full-bandwidth, low latency, direct microphone signals to be mixed and processed for local sound reinforcement purposes, ensuring a superior audio experience.

In summary, the Soundweb London Acoustic Echo Cancellation (AEC) Input Cards offer a comprehensive solution for enhancing your audio setup, providing you with clear, high-quality sound, free from interference and echo.
