Bolanle NK2 Inline Microphone Preamp with Switchable +10dB/+18dB Gain, 48V Phantom Powered Dynamic Mic Booster for Ribbon & Dynamic Mics, Podcast, Streaming, Recording

The +10dB setting provides a gentler, natural-sounding gain boost — ideal for moderately sensitive dynamic mics, instruments, or situations where your interface already provides moderate gain and you just need a clean lift. The +18dB setting delivers maximum boost for low-output dynamic mics like the SM7B, SM58, or passive ribbon microphones, where your interface's gain knob alone can't provide enough clean signal. We recommend starting with +10dB and switching to +18dB if your signal level is still insufficient.

• SWITCHABLE +10dB OR +18dB GAIN — THE RIGHT BOOST FOR EVERY MIC AND EVERY SITUATION – Most inline preamps lock you into one fixed gain setting. The NK2 gives you a choice: flip to +10dB for a natural, musical boost with condenser-like interfaces where headroom is generous, or engage +18dB when you need maximum gain for low-output dynamic mics like the SM7B, SM58, or any passive ribbon — without ever touching your interface's gain knob.
• 48V PHANTOM POWERED — ZERO EXTRA POWER SUPPLIES, ZERO CABLE CLUTTER – The NK2 draws all its power directly from your audio interface's 48V phantom power supply. No batteries. No wall adapters. No extra cables. Just connect your dynamic or ribbon mic to the XLR input, plug the output into your interface, enable 48V phantom power, and you're recording with pristine amplified signal in under 10 seconds.
• ULTRA-LOW NOISE CLASS-A CIRCUIT — CLEAN GAIN WITHOUT COLORATION – Built around a Class-A transistor amplification stage, the NK2 adds up to +18dB of pure, transparent gain while keeping self-noise at an absolute minimum. You get more signal, not more hiss. Whether you're recording vocals, podcasting, or live streaming, your dynamic microphone's natural character comes through exactly as intended — just louder and cleaner.
• UNIVERSAL XLR COMPATIBILITY — WORKS WITH VIRTUALLY ANY DYNAMIC OR RIBBON MICROPHONE – The NK2 connects inline between your microphone and audio interface via standard XLR connectors. Compatible with Shure SM7B, SM7dB, SM58, Electro-Voice RE20, Rode Procaster, AKG D5, Sennheiser MD421, and any passive dynamic or ribbon microphone that needs a gain boost. Gold-plated XLR connectors ensure reliable, corrosion-resistant signal transfer for years of use.
• COMPACT METAL BUILD — BUILT FOR STUDIO, STAGE, AND BROADCAST – Housed in a rugged, all-metal chassis, the NK2 is engineered to withstand daily professional use. Its slim inline form factor sits cleanly between your mic and preamp without adding bulk or weight to your mic stand. Ideal for home studio recording, podcast production, live streaming setups, broadcast booths, live stage vocal mics, and any application where a clean, reliable gain boost is needed.
