AI Noise-Canceling Microphone

I. Important Points to Note

  1. Before powering up the new board, use an ammeter to check if the overall current is normal. If the current is too high, it may burn the chip.

  2. The microphone audio channel switches, MIC-A and MIC-B, should be toggled alternately during testing. Turning both on simultaneously will cause the sound to become quieter.

3. Attention

When connecting dynamic microphones to the XLR channel, make sure to turn off the +48V switch to avoid damaging the microphone.

  1. The 10dB, 20dB, and 30dB switches correspond to the indicated gain values and should not be turned on simultaneously. Only one switch should be turned on at a time, and the other two should be off. For example, if 10dB is turned on, the other two must be off.

  1. The white power indicator light next to the USB is too bright and may be blinding. You can replace the resistor with a 1.2-1.5K value.
