The sE Electronics DM3 Active Inline DI is an active inline DI featuring an Ultra-HiZ input and a remarkably compact design, created to be your reliable companion for optimizing your instruments. Drawing from the well-established DYNAMITE technology found in the DM1 and DM2, the DM3 sets a new standard for active inline DI devices. Its Ultra-HiZ input and dedicated Class-A output buffer amplifier ensure your instrument's unique sound character is preserved with exceptional detail. This versatile device is suitable for a wide range of sources, including vintage electric guitar/bass pickups, piezo-equipped acoustic instruments, high-output sources like keyboards, synthesizers, drum machines, and laptops. With its generous headroom and switchable attenuation pad, the DM3 can handle even the most powerful output, such as a 10,000-watt solid-state power amplifier. The three-position ground lift switch, including a unique “on+” setting, effectively reduces buzz, hum, and unwanted radio interference noise. Equipped with a lockable 1/4” input jack, the DM3 ensures a secure connection in demanding live or recording environments. Crafted with a sturdy all-metal housing and an inline format to save space, the DM3 is more than just a box; it is a compact all-rounder, designed for exceptional sound quality.
