The Soundweb London Acoustic Echo Cancellation (AEC) Input Cards are designed to populate any of the four card slots on Soundweb London BLU-800, BLU-320, 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 6 dB steps from 0 dB to 48 dB.
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.
KEY FEATURES:
• Compatible with BLU-800, BLU-320, BLU-160 and BLU-120 Devices
• Phantom Power (Configurable per Channel)
• Software Controlled Analog Gain (0 dB to 48 dB, 6 dB steps)
• Four Independent Channels of AEC
• Individual Reference per Channel
• Automatic Gain Control (AGC)
• Noise Cancellation (NC)
• Non-Linear Processing (NLP)
• Direct Microphone Feed for Local Sound Reinforcement
