    About this Product

    The sE Electronics DM3 is a compact active DI box built for stage and studio use. Its Class-A output buffer delivers a clean, transparent signal path from instrument to desk, while the locking jack input ensures reliable connections in live environments. Designed for keyboards, guitars, bass, and any line-level source that needs converting to a balanced mic-level signal.

    Type
    Active
    Phantom powered

    Input
    Hi-Z
    Locking 1/4″ jack

    Output
    Gold XLR
    Balanced

    Ground Lift
    3-Step
    Off / On / On+ (RF)

    Ground Lift Options

    The DM3 features a three-position ground lift switch rather than the usual on/off toggle. The third position (On+) adds additional RF filtering, which is particularly useful in venues with heavy wireless traffic or LED lighting interference.

    Note

    The DM3 requires 48V phantom power from your mixer, interface, or stage box. This is the standard silver finish — a black variant is also available.
