BSS BLUAEC-IN 4-Analog Input Mic/Line Card for Soundweb London Chassis

BSS Audio BLUAEC-IN 4 Analog Input Mic/Line Card for Soundweb London Chassis Overview
The BSS Audio BLUAEC-IN Analog Input Mic/Line Card is an essential component designed to enhance your Soundweb London system by adding four independent channels of Acoustic Echo Cancellation (AEC). This card is compatible with several Soundweb London devices, including the BLU-800, BLU-805, BLU-806, BLU-320, BLU-325, BLU-326, BLU-160, and BLU-120 models. The BLUAEC-IN enables effective echo cancellation in conference systems, eliminating the disruption caused by echo when sound from loudspeakers enters microphones in the same room.

Enhanced Acoustic Echo Cancellation for Clearer Communication
One of the standout features of the BLUAEC-IN card is its ability to handle acoustic echo cancellation, which is critical in environments where microphones and loudspeakers are used in close proximity. By isolating the microphone input from sound entering through the speakers, the AEC technology provides clear communication in conferencing applications. The card’s four independent AEC channels allow for flexible configuration and optimization, ensuring that each room or space has its own unique solution, all handled by a single device.

Flexible Gain Control and Phantom Power for Versatile Use
The BLUAEC-IN card offers precise control over audio input with software-controlled analog gain in 6dB steps from 0dB to 48dB per channel. This feature is crucial for fine-tuning microphone levels in various environments, ensuring optimal audio performance regardless of room acoustics. In addition, each channel is equipped with phantom power, which can be configured per channel, making the card suitable for a wide range of microphone types and providing users with the flexibility to accommodate both condenser and dynamic microphones.

Automatic Gain Control and Noise Cancellation for Improved Audio Quality
To further enhance the audio experience, the BLUAEC-IN card includes Automatic Gain Control (AGC), which automatically adjusts the microphone input to maintain optimal audio levels. This feature is especially beneficial in environments where sound levels fluctuate, such as conference rooms or auditoriums. Additionally, the card features noise cancellation (NC) to remove steady-state background noise, such as hum from air conditioning or projectors, preventing unwanted sounds from being amplified and ensuring clean, clear audio transmission.

Advanced Non-Linear Processing for Dynamic Audio Adjustments
The card is equipped with Non-Linear Processing (NLP) to minimize echo caused by improper cancellation levels. This dynamic adjustment ensures that echo is continuously managed, even when environmental factors change. The BLUAEC-IN card intelligently adapts to under or over-cancellation scenarios, offering consistent and high-quality audio performance throughout its operation, without manual intervention.

Direct Microphone Feed for Local Sound Reinforcement
In addition to its AEC capabilities, the BLUAEC-IN card also provides a direct microphone feed for local sound reinforcement. This feature allows full-bandwidth, low-latency, direct microphone signals to be mixed and processed for immediate use in local audio systems. This makes it a versatile solution not only for conference systems but also for live sound reinforcement, ensuring that all aspects of the audio experience are managed with precision.
