Some microphones require a significant amount of gain, and not all preamps can handle this demand. Enter the sE Electronics DM1 Dynamite Active Inline Microphone Preamp with 28dB Gain - an ultra-slim active inline preamp that seamlessly integrates between your mic and preamp, offering a substantial +28dB of clean, transparent gain for all your passive microphones. Equipped with a sophisticated class-A design and top-notch high-grade FETs, the DM1 boasts markedly lower output impedance and nearly half the noise compared to other options on the market. Its gain remains a consistent 28dB, irrespective of the connected load, thanks to its dedicated buffer amplifier. The DM1 serves as an ideal solution to amplify the signal from a passive mic, decrease interference risks, and deliver a significantly enhanced level to your preamp without introducing noise or altering the sound. Notably, its output impedance is the lowest in its category, enabling it to drive lengthy cable runs while minimizing vulnerability to RF interference, buzz, and hum. The sturdy all-metal design, reliable construction, and high-quality manufacturing standards guarantee dependable operation even in challenging on-stage settings and demanding environments.
