The sE Electronics DM3 Black is a compact active DI box built for stage and studio use, finished in black to match darker stage setups and pedalboards. 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.
