SE Electronics DM1 Dynamite Active In-line Microphone Preamp with 28dB Gain

The DM1 Dynamite is an active in-line microphone preamplifier that sits between a passive ribbon or dynamic microphone and your mic preamp. It adds 28 dB of clean gain to lift quiet sources without adding noise or coloration.

Built around a Class-A FET design with low self-noise, the DM1 includes a dedicated output buffer to drive long cable runs and reduce RF interference, buzz, and hum. The slim all-metal housing is road-ready, connects via standard 3-pin XLR, and runs on 48V phantom power.
