NE5532 Stereo Dynamic Microphone Pre-amplifier Module

Ultra-small dynamic microphone pre-amplifier dual-channel design, suitable for single-cell lithium battery power supply, using fever operational amplifier chips NE5532, AD828 and TDA1308, of which TDA1308 is suitable for low-voltage power supply (3V-6v).

This microphone amplifier board does not have a power supply voltage stabilization circuit. When in use, it can only be powered by a battery or a linear regulated power supply, and cannot be powered by a switching power supply, otherwise there will be interference.

Note: If you only need to use one channel, the input of the other channel needs to be connected to GND (ground).
