An inline preamp for explosive levels from all your dynamics & passive ribbons




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.

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.
