Simple plugandplay connection: just plug the microphone amplifier into the microphone's XLR output port. CLASSA amplifier circuit design with the MP5 transistor: delivers lower audio output impedance and stronger load capacity for stable performance. Gain of 28 dB with low noise: a practical solution for low microphone volume caused by low sensitivity. Professional microphone enhancer: an active builtin preamplifier inserted between the preamplifiers of passive ribbon or dynamic microphones. Use scenarios and applications In a home or project studio to boost the signal of a lowoutput microphone, producing clearer and louder vocals or instruments without added noise. In studio sessions using passive ribbon or dynamic microphones, inserted between the mic and preamps to strengthen the signal and improve load handling. In live streaming or broadcasting setups where quick setup and reliable, lownoise gain are needed for consistent microphone levels.
