?Dynamic Microphone Amplifier 5V Power Supply Single Channel Increase Omnidirectivity for Dynami ??

The professional microphone enhancer is an active built-in preamplifier that is inserted between the preamplifiers of passive ribbon or dynamic microphones.
+28DB gain: The amplifier circuit has low noise, which is a good solution to the problem of low microphone volume due to low sensitivity.
The CLASS-A amplifier circuit design is used, and the high-order transistor MP5+ has a lower audio output impedance and a stronger load capacity.
Simple connection, plug and play: just plug the microphone amplifier into the microphone’s XLR output port.
This amplifier is only suitable for wired dynamic microphones connected to 3.5MM jack sound cards, and only requires 5V power supply.
