AI Noise Reduction Microphone¶
I. Control Precautions¶
-
Before powering on a new board, connect an ammeter to check if the overall current is normal to prevent excessive current from damaging the chip.
-
The MIC-A and MIC-B switches for testing microphone audio channels can only be switched alternately. Enabling both simultaneously will cause reduced volume.
3. Important Note
When connecting a dynamic microphone to the XLR channel, turn off the +48V switch to prevent damage to the microphone.
- The 10dB, 20dB, and 30dB switches should be enabled alternately according to the marked gain value. Only one marked switch can be enabled at a time; the other two must be disabled. For example, if enabling 10dB, the other two must be disabled.
- The white power indicator light next to the USB port is too bright and glaring. The resistor can be changed to 1.2-1.5K.
