sE Electronics DM1

sE Electronics DM1 Dynamite Microphone preamplifier from sE Electronics is an active inline preamp intended to be inserted between a passive ribbon or dynamic microphone and a microphone preamplifier (sold separately). It can be used to deliver a robust 28 dB of gain to boost the audio signal of a passive mic, which improves the level to a preamplifier without adding noise or coloration.

With a sophisticated class-A design and high-grade FETs, the DM1 has a low self-noise. It is built with a dedicated output buffer amplifier allowing it to drive long cable runs and reduce RF interference, buzz, and hum. Additionally, the DM1 Dynamite Active Inline Microphone Preamplifier offers a roadworthy, slim, all-metal design ensuring reliable operation for on-stage applications in difficult environments.
