Equipped with high-performance DSP processors and cutting-edge AI algorithms, the HPA-0202DP/20 features built-in Adaptive Feedback Cancellation (AFC) and Automatic Echo Cancellation (AEC) to quickly and effectively suppress acoustic feedback and echo. With adaptive filtering, it requires minimal setup and is ready to use, providing an additional 12dB of gain before feedback occurs to ensure clear and natural sound quality. Coupled with the TSW-0202DP parameter setting tool, users can easily customize their settings. It is widely used in on-site meetings, remote conferences, education, and other applications where it is necessary to increase ambient sound pressure and prevent system howling.
