High Material: Dynamic microphone amplifier is suitable for recording the studio to enhance the signals of the instrument source (such as vocal music, the musical instrument or acoustic instrument) while maintaining the natural sound of the microphone.

Add Clean Gain: Boosting the source signal without the unwanted noise. Professional dynamic microphone amplifier is used in standard phantom power can provide up to +25 dB of clean gain for XLR microphone input devices.

Applicability: The microphone activator can be used with all passive dynamic microphones.

Empower Your Microphone: TONOR TA20 microphone preamp provides up to +20dB gain for passive microphones such as SM7B, without passing phantom power to the microphone itself, reducing unnecessary feedback noise while greatly improving microphone clarity. (48V phantom power required, not included in package)

Pure Sound: With advanced circuitry design, the TA20 microphone preamp translates into less total hamonic distortion (THD) 0.022%. With a high SNR of 88±1dB, the microphone's signal strength is enhanced, delivering an exceptional auditory experience that's free from unwanted noise and interference.
