The DM1 DYNAMITE: explosive level for all your passive mics.

Some mics need a LOT of gain – and not all preamps are up to the challenge. The DM1 DYNAMITE is an ultra-slim active inline preamp that fits seamlessly between your mic and mic pre, providing a massive +28dB of clean, transparent gain for all your dynamic and passive ribbon microphones – perfect for podcasting, recording, or live sound.

With a sophisticated class-A design and specially-selected high-grade FETs, the DM1 has vastly lower output impedance and nearly half the noise of anything else on the market. Additionally, the gain it provides is always a consistent +28dB regardless of the connected load, thanks to its dedicated buffer amplifier.

Whether you’re a podcaster, recording engineer, or running live sound, the DM1 is the perfect way to boost the signal from a passive mic, reduce the likelihood of interference, and provide significantly improved level to your preamp – all without adding noise or coloration. Its output impendence is also the lowest in its class, allowing it to drive long cable runs while reducing susceptibility to RF interference, buzz and hum.

Reliable operation even in demanding on-stage applications in difficult environments is ensured by the roadworthy and slim all-metal design, robust construction, and high-quality manufacturing standards.


For optimum results, we recommend you plug the DM1 directly into your microphone’s output. If necessary, a cable can be used between the microphone and the DM1 – but the shorter the cable, the better the overall performance will be.

“To me, sE Electronics’ DM1 Dynamite is like something from a Harry Potter world: a magic stick that adds or subtracts nothing to/from the original microphone and that allows you to place it at a comfortable distance.”

“The DM1 Dynamite may deliver a big gain, but it’s even bigger in its proficiency to completely disappear from auditory perception and that’s what makes this thing a must-have with mics that are hard to drive.”

Visuals Producer, November 2018

“If you are looking for a solid, high gain signal booster that almost meets the old engineering goal of a ‘wire with gain’, I’d say sE Electronics have created it.”

Sound-Guy (Dennis Wilkins)

“They are beyond what I expected…the amount of gain and cleanliness is fantastic.”

– Patrick Derivaz, Producer / Composer / Engineer / Performer (Laurie Anderson, Phillip Glass)

“I think it’s really impressive: the color is almost gone. If anything, the signal is somewhat refined…I already had similar products that did not convince me that much. The concept is well thought out and well implemented….for the price you can make no mistake here in the purchase.”

“Best of its kind. I use the DM1 with a Shure SM7b, a notoriously gain-hungry microphone. I also use a Focusrite Scarlett Solo Second Generation with it. This piece of equipment allowed me to drop my gain to about 35-40% virtually eliminating any Pre-amp noise. I definitely recommend this, especially if you use an SM7b.”

“My 3 piece band can get loud and vocals get lost. I used this for the first time last Sat, and IT WORKS !! My vocal volume setting is now half what it used to be. Does just what it says. No coloring of the sound.”

”It Works! An sE V7 and DM1… I couldn’t be happier!”

“It’s beautiful when a product works as advertised. I learned when trying to make some spoken word recordings that the SM57 needs a big preamp boost which my interface (a Zoom H4n) did not provide. Using 100% gain yielded at tops a -20 dB level for normal speech. The quality of the signal was muffled and there was a ton of room noise. With this product I could reduce the gain to 50 and get a sparklingly clear signal. I was also able to speak farther from the mic, which was a better capture for my voice…The simplicity of use is just as great as its performance.”

“Fantastic for spoken word, podcasting, and acoustic instruments. You can use a dynamic mic or passive ribbon mic for quiet sources like shaker, acoustic guitar, mountain dulcimer, or banjo.”

“The sound is very good. I got a little more high end out of the microphones, and it seems that the dynamics were a little more lively and dynamic. Transients just a touch more punchy. This was a big plus.”
