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 passive microphones.

 
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.

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.

USER QUOTES

“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.”
