Acxico 3Pcs AD828 Stereo Dynamic Microphone Preamplifier Board Pickup Module DC 3.8V-15V MIC Preamp Module

  • The piezoelectric ceramic piece is sensitive to the sound wave vibration transmitted by the solid, and is not sensitive to the acoustic vibration of the gas, which can effectively reduce the environmental noise and avoid the whistling caused by the self-excitation. Can be used for guitar, erhu and other musical instruments..
  • Ultra-small volume dynamic microphone preamplifier board,two-channel design,suitable for a single lithium battery-powered,using AD828 fever op amp chip,suitable for low voltage power supply (3.8-15V).
  • If you only used one channel,the other channel needs to short-circuit the input with GND,To avoid interference with the signal crosstalk..
  • Working voltage:DC3.8V-15V.This microphone amplifier board without power regulator circuit,can only use the battery or linear power supply,can not use switching power supply,otherwise there will be interference..
