sE Electronics DM1 Dynamite Active In-Line Microphone Preamplifier

The red DM1 Dynamite Active In-Line Microphone Preamplifier from sE Electronics is an active 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 through the 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 In-Line Microphone Preamplifier offers a roadworthy, slim, all-metal design, ensuring reliable operation for onstage applications in difficult environments. The unit features standard 3-pin XLR connectors and requires 48V phantom power for operation.
