The sE Electronics DM2 (DM2 TNT) is an inline active microphone preamp designed to give passive microphones like dynamic and ribbon mics a clean, powerful gain boost without adding noise or changing their natural tone. It offers switchable gain of +15 dB or +30 dB, making it especially useful when your mic signal is too weak for your interface or mixer.
Built with a Class-A circuit and high-grade components, it delivers very low noise and a transparent signal boost, while its compact, all-metal body makes it reliable for both studio and live use. In simple terms, the DM2 is like a clean gain booster that brings out the best performance from passive mics without coloring your sound
Key Features
-
Active inline microphone preamp (not a mic or DI) – Designed to sit between a passive dynamic or ribbon mic and your audio interface/mixer
-
Clean gain boost (+15 dB or +30 dB) – Adds powerful, transparent gain without adding noticeable noise or coloration
-
Ultra-high impedance input (up to 10 MΩ) – Preserves full tone and detail of passive microphones
-
Eight impedance/load settings – Lets you match and fine-tune microphone response for different tones and sources
-
Class-A circuit design with high-grade FETs – Ensures ultra-clean, low-noise signal boost
-
Very low self-noise performance – One of the quietest inline preamps in its class
-
Buffer output stage – Drives long cable runs with stable signal and reduced interference
-
Gold-plated XLR connectors – Reliable, noise-free signal transfer
-
Compact all-metal body – Rugged and road-ready for stage and studio use
