sE Electronics DM1 Dynamite Inline Preamp

Active inline preamp for explosive levels from passive mics

Product Description

The sE Electronics DM1 Dynamite is an active inline preamp designed to provide +28 dB of gain for ribbon or dynamic microphones. Simply insert the DM1 between your microphone and preamp to boost the signal from passive mics without adding noise or coloration.


For decades, condenser microphones have been the go-to choice for recording intimate performances, however they don’t always provide the desired color and character. Sometimes a record calls for the dark, smokey tones of a vintage ribbon mic, or the punchy midrange of a dynamic mic. But trying to capture quiet performances often results in weak, noisy signals — until now.

The DM1 is the perfect way to boost the signal from a passive mic. With a cutting-edge, Class A design and hand-selected high-quality FETs, the DM1 offers minimal self-noise. Equipped with dedicated output buffer amplifier, the DM1 consistently delivers +28 dB of gain, regardless of the connection load.


Featuring the lowest output impedance in its class, the DM1 can drive long cable runs without RF interference, buzz and hum—allowing you to run lines from the stage to FOH or to far-off iso-booths in the studio.

The DM1 features a rugged, roadworthy, all-metal design with top-of-the-line manufacturing standards, providing rock-solid reliability demanding on-stage applications or in difficult environments.

For best results, it is recommended that you plug the DM1 directly into the output of your microphone. While you can connect a microphone to the DM1 using an XLR cable, shorter cables will result in better performance.


  • +28 dB of clean, consistent gain designed for neutral, balanced sound quality - the perfect way to boost the signal of a passive microphone, gain stays consistent regardless of connected load providing significantly improved level to your mic preamp for proper gain staging
  • Sophisticated Class-A electronics - state of the art electronics and high-grade FETs provide supremely low noise and transformerless design provides pristine sound quality and the lowest noise in its class
  • Dedicated output buffer amplifier provides +28 dB output independent of load impedance or cable length with extremely low output impedance - drives long cable runs and can reduce susceptibility to RF interference, buzz & hum
  • Gold-plated XLR connector for loss-free and reliable signal connection
  • Slim, rugged all-metal housing with premium finish
  • efficient rejection of any electrical interference and noise high-quality finish ensures a great look for many years, slim design allows for easy placement in the studio or on stage

I would like to thank VK for the wonderful sales assistance, service and prices. This was my first purchase with you and it won't be my last. I only wish I'd discovered you years ago!

In almost 20 years in Pro audio buying, never did I receive a unit so well packed and exactly as described. Works flawlessly. The whole process has been so smooth. I will never hesitate to do business with you guys in the future and will recommend you to everyone I know.

This was my first experience buying something from Vintage King (although I surf the "used" categories on the website frequently!), and, despite being on the other side of the world, I had absolutely no trouble and everything went very smoothly.

My experience with Vintage King was excellent. The order was here fast considering it was out of stock. The sales person had SKB send it to me directly and I couldn't have been more pleased.

From the minute I placed my order I was kept well-informed through each step in your process. Even though I was buying a comparatively modest piece of gear, your attention to detail made me feel like I was purchasing a six-figure mixing desk.
