Description
The Harman BSS BSSBLUAECIN-M AEC Card is a 4-channel analog mic/line input expansion card designed for Soundweb London digital signal processing platforms. Engineered for conferencing and collaboration environments, this card delivers independent Acoustic Echo Cancellation (AEC) processing on each channel to eliminate echo caused by loudspeaker-to-microphone audio bleed within the same space.
Compatible with Soundweb London chassis devices including BLU-800, BLU-805, BLU-806, BLU-320, BLU-325, BLU-326, BLU-160 and BLU-120, the BSSBLUAECIN-M installs directly into any available card slot, providing flexible system expansion for meeting rooms, boardrooms, courtrooms, lecture halls, and multi-zone conferencing spaces.
Each channel features software-configurable phantom power and analog gain control adjustable in 6 dB steps from 0 dB to 48 dB. Independent AEC references allow multiple spaces to be managed from a single processor. Built-in Automatic Gain Control (AGC), Noise Cancellation (NC), and Non-Linear Processing (NLP) ensure consistent vocal clarity, background noise suppression, and optimized echo control performance.
A direct microphone feed is also provided for local sound reinforcement, delivering full-bandwidth, low-latency audio for in-room mixing and processing applications.
Ideal for professional AV integrators seeking scalable, high-performance conferencing DSP solutions.
