sE Electronics DM1 Dynamite Black - Mic Preamp

The sE Electronics DM1 Dynamite is a compact, active in-line microphone preamplifier designed to boost the signal of dynamic and passive ribbon microphones by +28 dB of clean, transparent gain. Its all-metal housing ensures durability, while the Class A circuitry delivers low noise and high headroom. Ideal for improving signal-to-noise ratio and driving long cable runs, the DM1 requires 48V phantom power and connects directly between your microphone and preamp or audio interface via XLR connectors.
