sE Electronics DM1 Dynamite

Active In-Line Microphone Preamplifier

The sE Electronics DM1 DYNAMITE is an active inline microphone preamplifier designed to provide 28 dB of clean, consistent gain for passive dynamic and passive ribbon microphones. Its slim XLR design installs directly between a microphone and mic preamp, mixer, or audio interface, helping low-output microphones achieve stronger signal levels without excessive preamp gain.

sE Electronics DM1 DYNAMITE Competitive Differences

• Provides 28 dB of clean, consistent gain for passive dynamic and passive ribbon microphones
• Class-A design with specially selected high-grade FETs provides transparent signal amplification
• Dedicated output buffer delivers a low 135-ohm output impedance for driving long cable runs
• Low output noise helps maintain clarity when boosting low-output microphones
• Wide 10 Hz to 120 kHz frequency response preserves the microphone's original signal character
• Gold-plated XLR connectors provide reliable signal connections
• Slim all-metal housing is built for demanding studio, broadcast, and live applications

sE Electronics DM1 DYNAMITE Description

The sE Electronics DM1 DYNAMITE gives gain-hungry passive microphones an additional 28 dB of level before their signal reaches a conventional microphone preamp. This makes it especially useful with low-output dynamic microphones and passive ribbon microphones used for podcasting, vocals, broadcasting, studio recording, and live sound.

The Class-A circuit uses specially selected high-grade FETs to amplify the microphone signal with minimal coloration. A dedicated output buffer maintains consistent gain while providing a low output impedance, helping the DM1 drive long microphone cable runs with reduced susceptibility to RF interference, buzz, and hum.

With a frequency response of 10 Hz to 120 kHz and an output noise level of 9 µV A-weighted, the DM1 is designed to preserve detail while adding the level needed for cleaner gain staging. Its compact form factor requires no external controls and connects directly into a standard XLR microphone signal path.

The rugged all-metal red housing and gold-plated XLR connectors are designed for reliable use on stage, in recording studios, and in broadcast environments. The DM1 operates from standard 48V phantom power supplied by the connected microphone preamp, mixer, or audio interface and is intended specifically for passive dynamic and passive ribbon microphones.
