FBX3000 10-way professional digital feedback suppressor Scope of application: Meetings, theaters, auditoriums, classrooms, multi-purpose halls and other places with high-level sound requirements Features: A high-speed feedback suppressor that can accept 10 microphone inputs and 2 balanced outputs. Each microphone has independent 48V phantom power and gain adjustment. Two Lotus line inputs and outputs and two music inputs. The panel is equipped with a display screen that can display the current working status and signal level. Panel pass-through and feedback can be switched with one button. 10 microphone inputs with built-in automatic mixer. In many situations, such as at a podium or conference table, using two microphones can better capture the voice of a moving speaker, often increasing the risk of acoustic feedback. Due to this problem, the automatic mixer will automatically reduce the gain of the microphone with the weaker signal input, while increasing the gain of the other microphone with the stronger signal input. This way, it can track the speaker on the move, producing optimal sound clarity.
