Description
FQA-8400 intelligent professional audio power amplifiers management with AEC function
FEATURES:
The digital intelligent management power amplifier is mainly for modern teaching, meeting, court trial of local amplification, recording and remote call to specially research and development. Adopting modular design, Under different of project needing, and matching the corresponding module function, to save the cost of engineering. This intelligent amplifier design is flexible and varied, have 8 channel MIC input , each 4 channel divides into A area and B area, There are independently select one from four of automatic mixing function and environmental noise elimination function of two areas. According to different situations require to separate access or bypass. With high speed automatic feedback function, can prevent local amplifier, caused by the noise, and promote sound pressure and clarity. Built-in 4X100W channel power amplifier, stereo bridge and transformation. It is satisfy for teaching,meeting and court trial needs.
