AI Noise-Canceling Microphone¶
I. Control Precautions¶
-
Before powering on a new board, connect an ammeter to check if the overall current is normal to avoid burning the chip due to excessive current.
-
When testing channel microphone audio, the MIC-A and MIC-B switches can only be tested by alternating them. Enabling both simultaneously will result in reduced volume.
3. Caution
When connecting a dynamic microphone to the XLR channel, ensure the +48V switch is turned off to prevent damage to the microphone.
- The 10dB, 20dB, and 30dB switches should be toggled individually to achieve the corresponding gain values. Only one switch should be enabled at a time, with the other two disabled. For example, when enabling 10dB, the other two must be disabled.
- The white power indicator light next to the USB port is excessively bright and may cause eye strain. The resistor can be changed to 1.2-1.5K to reduce brightness.
