## Description

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

## Features

- 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.
- Size:2.5x1.6cm/0.98x0.63inch

## Questions & Answers

**Q: does this circuit have dc blocking caps?**
A: I don't know since I have never seen a schematic for this product.   Why not, just assume 
none were provided and install them external to the board .... just to be safe rather than sorry  !

**Q: Can this be used with an electret mic?**
A: YES,   but only as far as for amplification.  You will need to come up with the  voltage
to be applied to the Mike Element.  Might I mention that his board has no easy means of gain adjustment.  I think there are other Pre-Amplifier boards that provide the voltage to supply the element. and pads to solder on adjustment resistors to select gain.

**Q: What is the input impedance**
A: Impedance is not mentioned,
check out the Velleman  K-1803  which was my second purchase.  mono pre-amp.  Works like a champ !

**Q: How do I verify operation? I have tried two different boards with two different microphones. I am not getting any output.**
A: my has a heat sink under 
not all the board work the same
waith till i get mine and try to tell a is wirwd
