It can automatically recognize the warning signals and filter noise through the DSP system. There is a low frequency compensation function and high mixing speed feedback suppression. When using multiple microphones at the same time, it will adapt to the acoustic environment automatically without additional configuration. automatic calibration function ensures high sound quality and reducing signal delay. There are three variants of high, medium and low level to help prevent distortion and enhance the sound distance of 30 – 100 cm.
Configuring:
1. This device is equipped with a powerful DSP system which will filter alarms. Actively protect and maintain the original signals.
