Feedback Suppressor

HPA-0202DP/20
Feedback Suppressor

• Apply to local and teleconferencing congress system
• High-performance DSP processor,cutting edge feedbacksuppression and echo cancellation algorithms suppressacoustic feedback effectively, for making fast processorspeed and better sound quality
• AI algorithm with strong self-learning ability, effectivelyfilter out room reverberation to achieve the purpose ofeliminating acoustic feedback, and greatly improve thetimbre difference between through and feedbackprocessing
• Line In/Out: for Live audio signal input/output
• VCS In/Out: for Teleconferencing audio signalinput/output
• Build-in Adaptive Feedback Cancellation(AFC) andAutomatic Echo Cancellation(AEC) switch
• According with the environment, the automatic adaptive filter adjust amount of computation to achieve bestperformance, get extra 12dB gain before acousticfeedback happens
• Adpot self adaptive full duplex and all frequency bands echo elimination algorithm
• Adaptive noise cancellation algorithm, which can filterout background noise without affecting the speaker'svoice, the 15 dB noise reduction effectively improve thesignal-to-noise ratio to improve the sound quality
• Widely used in on-site conferences, remoteconferences, teaching and other application scenariosthat need to increase the ambient sound pressure andprevent the system from whistling
