The CLASSA amplifier circuit design uses a MP5+ transistor to deliver lower audio output impedance and higher load capacity, providing stable drive and clearer signal to the connected microphone. The professional microphone enhancer is an active builtin preamplifier that is inserted between the preamplifiers of passive ribbon or dynamic microphones, improving the mic signal in the chain. Simple connection, plug and play: just plug the microphone amplifier into the microphone's XLR output port for quick setup and operation. +28 dB gain: The amplifier circuit has low noise, addressing the problem of low microphone volume caused by low sensitivity and helping achieve stronger, cleaner output. Use scenarios Home studio vocal recording with a dynamic microphone that needs extra gain without raising noise levels. Live performance or onstage use with a passive ribbon or dynamic microphone to ensure adequate signal level and reliable load handling. Podcasting or voiceover setups using lowoutput microphones to achieve sufficient volume with clean, quiet operation and minimal equipment. Key attributes Function: active builtin preamplifier that enhances microphone signal in the preamp chain. Compatibility: suitable for passive ribbon and dynamic microphones that connect via XLR. Performance: provides +28 dB gain with low noise and improved drive characteristics thanks to the CLASSA design and MP5+ transistor. Connection: plug and play via the microphone's XLR output port for fast, straightforward setup.
