DM1

The DM1 is an inline microphone preamp that adds a fixed +28 dB of gain to any dynamic or passive ribbon microphone. It plugs in between the mic and your mixer or interface and runs on 48 V phantom power, so there are no batteries and no extra channels involved.

Low-output dynamics and ribbons often leave a console preamp working near the top of its range, where hiss and coloration start to show. The DM1 supplies clean gain before that point: a Class-A design built around hand-selected FETs, 9 uV of output noise, and a 10 Hz to 120 kHz frequency range that stays out of the way of the microphone character. Output impedance sits at 135 Ohms, low enough to hold the signal together over long cable runs.

The +28 dB figure stays put regardless of the connected load, so results are predictable when the same mic moves between a studio console, a live desk, and a portable recorder. That consistency matters for podcast rigs running several dynamic mics, broadcast booths, ribbon mics on guitar cabinets and brass, and quiet acoustic sources.

The housing is all-metal with a premium finish made for touring and daily studio work, and gold-plated XLR connectors keep the connection reliable through repeated patching. At 19 mm across and 96 mm long, it disappears behind a mic clip or into a patch bay without crowding the setup.
