Product Detail

Detailed

This is a high speed feedback suppressor that can be connected to 10 microphone inputs and 2 balanced outputs. Each microphone with independent 48V phantom power and gain adjustment. Two Lotus line inputs and outputs and two music inputs. The panel is equipped with a display that shows the current operating status and signal level, and the panel switches between pass-through and feedback at the touch of a button. 10 microphone inputs have a built-in automatic mixer. In many cases, such as on a podium or conference table, two microphones can better capture the voice of a moving speaker, which often increases the risk of acoustic feedback. With this in mind, an 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. In this way, it can track a moving speaker and produce optimal sound clarity.
