Using CLASS-A amplifier circuit design, with high-order transistor MP5+, lower audio output impedance, and stronger load capacity.Simple connection, plug and play: just plug the microphone amplifier into the microphone's XLR output port.
The sound card + microphone amplifier can provide 28DB of pure gain, which is equivalent to directly increasing the sound card microphone amplifier by 28DB without affecting the sound quality. Instead, it can reduce the noise problem caused by excessive gain of the sound card itself.
The professional microphone enhancer is an active embedded preamplifier that is inserted between the preamplifiers of passive ribbon or dynamic microphones.
Built-in lithium battery, 5 hours of battery life, no additional power supply required. the amplifier switch, and the power-on light turns red, and the amplifier can be used. When charging, the charging indicator light turns red, and when fully , the charging indicator light turns green.
