Description
BSS BLUAECIN 4 Analog Input Mic/Line Card for Soundweb London ChassisThe Soundweb BLUAEC IN London Acoustic Echo Cancellation (AEC) Input Cards are designed to populate any of the four card slots on Soundweb London BLU 800, BLU 805, BLU 806, BLU 320, BLU 325, BLU 326, BLU 160 and BLU 120 devices. These AEC Input Cards enable Soundweb London devices to cancel acoustic echo arising when sound from a loudspeaker enters a microphone in the same room in a conference application.

The Soundweb BLUAEC-IN London Acoustic Echo Cancellation (AEC) Input Cards are designed to populate any of the four card slots on Soundweb London BLU-800, BLU-805, BLU-806, BLU-320, BLU-325, BLU-326, BLU-160 and BLU-120 devices. These AEC Input Cards enable Soundweb London devices to cancel acoustic echo arising when sound from a loudspeaker enters a microphone in the same room in a conference application.
Like the Soundweb London Analog Input Cards, the Soundweb London AEC Input Cards offer Phantom Power, configurable per channel and software controlled analog gain in 6dB steps from 0dB to 48dB.
They offer four independent channels of AEC which can be freely configured in software and individual AEC references allowing users to provide a solution for multiple spaces using a single device.
Automatic Gain Control (AGC) ensures that the inputs of the microphones are set at the optimum level. Noise Cancellation (NC) removes steady state noise (such as from a projector fan or air conditioning device) from the signal path. This stops the noise from being amplified.
Non-Linear Processing (NLP) dynamically adjusts to minimize echo caused by under or over-cancellation.
The Soundweb London 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.
