SE ELECTRONICS sE DM1 Dynamite Active Inline Microphone Preamp

The sE DM1 Dynamite is a compact, high-performance active inline microphone preamplifier designed to boost the signal of dynamic and passive ribbon microphones without adding noise or coloration. With a fixed +28 dB gain, ultra-low noise floor, and Class A circuit design, it delivers pristine audio quality in a rugged all-metal chassis. Ideal for studio and live applications, the DM1 Dynamite connects directly between your microphone and mixer or audio interface, requiring 48V phantom power.

Advantages

• Transparent +28 dB gain with minimal distortion (THD+N 0.002%)
• Ultra-low noise (EIN 9 dB A-weighted) for clean signal amplification
• Compact and rugged design fits easily in any setup
• Compatible with dynamic and passive ribbon microphones
• No external power supply needed; powered by standard 48V phantom power

Suitable for

• Studio recording with dynamic microphones (e.g., SM57, SM58)
