sE Electronics DM3 Inline DI Black - Compact Active DI

sE Electronics DM3 Inline DI Black – Compact Active DI

The sE Electronics DM3 is an ultra-compact in-line active DI that takes the DYNAMITE technology of the DM1 and DM2 to a new level of silence and fidelity. With a 10MΩ Ultra-HiZ input, it preserves the unique character of your instrument without loading it, and its dedicated Class A buffer amplifier provides a clean output with no signal degradation. Ideal for electric guitars, vintage basses, piezo pickups, keyboards, synthesizers, drum machines or laptops, the DM3 offers enormous headroom , handling signals up to the output of a 10,000W amplifier, and features a switchable –15dB/–30dB pad for controlling higher levels.

Main features

• Ultra-HiZ input impedance: 10 MΩ to preserve the tonality of pickups and piezos.
• Massive Headroom: Supports outputs up to 805 Vp-p (≈10,000 W) without distortion.
• Switchable pad: –15 dB and –30 dB integrated to attenuate excessive signals.
• 3-position ground lift switch: “On+” eliminates hum, buzz, and unwanted RF noise.
• Lockable ¼″ input jack: Secure connection that prevents accidental disconnections during live performance.
• Dedicated Class A Buffer: XLR output with low impedance circuitry for lossless signal.
• All-metal chassis: Rugged construction and space-saving inline form factor.
• Gold-plated XLR connectors: Excellent conductivity and corrosion resistance.

Product benefits

• Online Studio Quality: DYNAMITE technology delivers quiet operation and maximum fidelity.
• Live Reliability: Compact, lockable jack design for high-paced environments.
• Sound versatility: Compatible with any high or low output source.
• Noise Reduction: Ground-lift “On+” attacks hum, buzz, and RF simultaneously.

Use cases

• Direct connection of vintage guitars and basses to mixers or interfaces.
• Piezoelectric and acoustic instruments equipped with output for live performance or recording.
• Keyboards, synthesizers, drum machines, and high-output USB devices.
• Portable solutions for mobile streaming or recording anywhere.

Frequently Asked Questions

• Does it work without phantom power? No; the DM3 must be powered using 48V phantom power from the XLR input.
• Can I use it with microphones? It's optimized for instruments; for dynamic microphones, a passive DI box is best.
• How do I activate the pad? Press and hold the recessed switch for –15 dB or –30 dB depending on the signal.
• What does the ground lift's "On+" mode do? In addition to breaking ground loops, it attenuates radio frequency interference.
