The DM3 is a compact active direct box engineered for touring musicians, studio engineers, and live production teams who demand transparent signal integrity from electric guitars, basses, keyboards, drum machines, and playback devices. Its Ultra-HiZ input impedance of 10 megaohms places virtually zero load on your instrument, allowing the true character of your pickups and electronics to pass through uncolored. Whether you're capturing a vintage tube amp tone, a modern active pickup, or a hot keyboard output, the DM3 delivers clean, consistent signal at the mixer or interface.

Built around proven Class-A design and sE's DYNAMITE technology, the DM3 combines maximum headroom for hot signals with the lowest noise floor in its class. A three-stage ground lift switch with unique "on+" setting tackles buzz, hum, and RF interference in any environment—studio, stage, or house of worship. The recessed attenuation pad offers 15 or 30 dB of cut when needed, and the lockable 1/4" input jack prevents accidental disconnects during fast-paced live work. All-metal construction with gold-plated XLR output and an exceptionally compact form factor make this a reliable workhorse that fits in a pocket or clips to your keychain.
