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. The DM1 DYNAMITE is an active inline preamp intended to be inserted between a dynamic or passive ribbon microphone and a microphone preamplifier. The DM1 provides +28dB of discrete class-A gain, and offers nearly half the noise, significantly lower output impedance, and much more consistent gain than any other inline mic preamp on the market, thanks to its specially-selected high-grade components and dedicated output buffer amplifier. According to see, The DM1 Dynamite is the perfect way to boost the signal from a passive mic for studio, podcasting, or on-stage use. It also reduces the microphone's output impedance to minimize the likelihood of interference, drive long cable runs, and provide significantly improved level in your signal path - without adding noise or coloration.
