<p>This product's +28DB gain class A transistor amplifier circuit has low noise and effectively solves the problem of too low microphone volume due to low sensitivity.</p> <p>Transistor amplifier circuit, pure amplification without noise, using CLASS-A amplifier circuit design, paired with high-end transistor MP5+, lower audio output impedance, stronger load capacity.</p> <p>Simple connection, plug and play, directly plug the microphone amplifier into the XLR output of the microphone.</p> <p>The operation is simple and convenient. It is easy to connect various devices. It is directly connected to the microphone output port for seamless connection and better effect. By connecting the microphone preamplifier to the audio interface\/mixer input port, the wiring space can be flexibly set up. The microphone and microphone preamplifier are connected to the rear Level audio devices can be connected via cables.</p> <p>High-definition sound, anti-interference, and low noise reduction.</p> <p>Colour:Blue</p> <p>Material:Aluminum alloy</p> <p>Package Contents:</p> <p>3 * Microphone Preamp</p> <p>1 * Instructions in Chinese and English</p> <p>Only the above package content, other products are not included.</p> <p>Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing.
