FB3000 DIGLTAL FEEDBACK EXTERMINATOR

Application:

Description:

Using two microphones can better capture the voice of a moving speaker, and this often increases the risk of acoustic feedback. In view of this problem, the automixer will automatically reduce the gain of the microphone with the weaker signal input and increase the gain of the other microphone with the stronger signal input. In this way, it can track the moving speaker and produce the best sound clarity. High-speed feedback suppressor with 10 microphone inputs and 2 balanced outputs. Each microphone has an independent 48V phantom power supply and gain adjustment. Two-way lotus line input and output and two-way music input. The panel is equipped with a display screen, which can display the current working status and signal level, and the panel can be switched through and feedback with one button. 10 microphone inputs have built-in automatic mixer.
