Intelligent microphone processor
Unique voiceprint recognition level, used to determine whether the device is operating in the optimal voiceprint recognition state; By combining the "Line/Microphone" mode switch with the "High/Medium/Low" level selection switch and the "MIC" gain knob, it can adapt to multiple sets of different input level settings, enabling input level signals within the range of+6dBu to -80dBu to work in the optimal voiceprint recognition state; High precision floating point DSP processor, 24 bit A/D and D/A conversion, 96KHz sampling frequency; All three input interfaces are XLR XLR female sockets, with two input signals equipped with+48V phantom power supply and the other as line reference signal input to enhance voiceprint recognition feedback suppression function. Both output interfaces are XLR male sockets, and the two output signals are independently processed; Zero distortion: The voiceprint recognition method has the least damage to the human voice, and theoretically can achieve zero damage, that is, zero distortion!
