The DM3 is an active inline DI with an ultra-HiZ input and an impressively compact design – built to stay by your side, ensuring you always get the best out of your instruments! Based on the proven DYNAMITE technology used in the DM1 and DM2, the DM3 redefines the active inline DI to a new noise-free standard. Its ultra-HiZ input and dedicated Class-A output buffer amplifier preserve the unique tonal character of your instrument with flawless detail. Ideal for sources ranging from vintage electric guitar/bass pickups to piezo-equipped acoustic instruments and high-output sources like keyboards, synthesizers, drum machines, and laptops, to name just a few. Thanks to its massive headroom and switchable attenuation pad, the DM3 can handle the roaring output of a 10,000-watt solid-state power amplifier. The three-position ground lift switch features a unique "ON+" setting that efficiently reduces not only hum but also unwanted RF interference. With a locking 1/4-inch input jack, the DM3 provides a secure connection in the most demanding, fast-paced live or recording environments where snags can occur. Built with a robust all-metal housing and an inline form factor to save valuable space, the DM3 is less of a box and more of a compact all-rounder. It is certainly the key to great sound!.
