sE Electronics DM2 T.N.T – Active Inline Mic Booster with Load Control

The sE Electronics DM2 T.N.T is built for recording engineers, podcasters, live sound pros and anyone using passive dynamic or ribbon mics who need extra clean gain without losing tone. With selectable gains, multiple impedance settings, and ultra-low noise, it lets your source perform at its best—Soundium equips your setup so your mic speaks up clearly.

Key Features

• Selectable gain of +15 dB or +30 dB: Lets you choose moderate or strong boost depending on source level.
• Eight impedance (load) settings from 50 Ω to 10 MΩ: Match your mic to the ideal load to retain tone and clarity.
• Ultra-high input impedance and low output impedance (~135 Ω): Helps preserve signal quality, especially when using long cables.
• Class-A FET electronics, transformerless design: Clean sound, neutral character, minimal coloration.
• Powered by 48 V phantom power: Draws modest current (~3 mA), so as long as your preamp/interface supplies phantom you’re good.
• Solid all-metal build and gold-plated XLR connectors: Roadworthy construction ensures durability and clean connections.

Customer Benefits

With the DM2 T.N.T, you get control over your mic’s gain and how it interacts with your preamp, letting you extract more clarity, presence, and dynamics from passive mics or low-output sources. Less noise, fewer compromises. Whether you’re pushing vocal dynamic range, boosting a ribbon mic, or dealing with long cable runs, this device gives you flexibility and transparency. Soundium provides gear like this to ensure your setup adds fidelity, not obstacles.

Use Cases / Ideal For

Perfect for upgrading dynamic or ribbon mics, especially in noisy or challenging environments. Great for podcasting, streaming, live stage, or any setup where your mic signal needs a clean push before it hits your preamp. Also useful when using long cable runs or when you want to experiment with mic load to fine-tune character. Ideal for engineers who want both control and quality.

Compatibility

Use with passive dynamic or ribbon microphones (not condenser mics requiring internal phantom). Requires a preamp/interface with 48 V phantom power. Use balanced XLR cables. Best placed as close as possible to the microphone to minimize cable noise. Check that your preamp can still supply clean gain after the inline device.

Pros & Cons

✅ Pros:

• Great gain options for low-output mics without investing in new preamps.
• Flexible load settings let you tweak tone and response by matching impedance.
• Low output impedance helps with cable runs and maintaining clean signal paths.
• Durable build suitable for both studio and stage use.

⚠️ Cons:

• With +30 dB gain in high load settings, some hiss becomes audible, especially at low frequencies.
• Not suitable for condenser microphones or active ribbon mics that already require phantom or internal power.
• Length and width of inline unit add some bulk close to mic; may interfere slightly with tight placements.

The sE Electronics DM2 T.N.T is an inline solution for boosting passive mic signal with integrity and flexibility. Your dynamics, your ribbons, your low-output sources get new life with minimal noise and maximal control—Soundium brings this kind of gear so you can shape sound freely.
