01 Introduction

The series of products is a new generation of digital ultra-high-speed feedback suppression system designed for professional conference systems. It adopts the algorithm of the high-speed floating-point digital signal processor of Langgu Digital Laboratory, applies the industry-leading digital audio processing and 24BIT 196HZ audio digital chip technology, powerful computer processing capabilities and high-performance functional applications, and brings to the on-site audio engineers fully adaptive software without debugging. Its automatic analyzer can automatically measure the distance between the microphone and the speaker and adjust the feedback suppressor. There is no need for operation and debugging, so as to obtain clear, accurate, stable and reliable voice signals.

It is widely used in network conferences, audio and video remote conferences, telephone conference systems, etc. This series of products has been successfully deployed in a large number of conference centers and has been favored by more and more users.
