CEntrance MicPort Pro 3 Portable Mic Preamp with Analog limiter + USB-C Audio Interface


For busy creatives who travel light, MicPort Pro is a portable USB mic preamp that makes it easy to record on-the-go, with professional quality. Ideal for speech and music recording, MicPort Pro can turn your phone into a recording or a live-streaming studio. Smaller than most mics, MicPort Pro is feature-rich, easy to use, and travel-friendly.

Now on its 3rd Generation, MicPort Pro features improved mic preamp with 65 dB of clean gain(great for SM7B, RE-20 and other dynamic mics), extra 6dB gain in the headphone amp (great for recording interviews on busy city streets), and USB-C jacks for modern compatibility and convenience.

A built-in, rechargeable battery sets MicPort Pro apart from other portable audio interfaces, making it your ideal companion for the road. Now you can record  directly to your phone or tablet and leave that laptop behind. The low-noise Jasmine™ mic preamp, zero latency blend control and a musical, soft-knee limiter combine to create a professional vocal processor, putting MicPort Pro in a class of its own.

Record, edit and share your work online. From anywhere. Other recording interfaces are either tied to the wall plug or go through batteries too quickly. MicPort Pro lasts the entire session on a full charge and works anywhere you go — perfect for podcasting, broadcasting, interviewing and streaming live from location.

If you are a voice-over actor, broadcaster or radio journalist, you already know the CEntrance MicPort Pro Classic. That breakthrough audio interface connected any professional mic to a computer for making professional recordings on the go. Endorsed by 100+ broadcasters, including Beau Weaver and Joe Cipriano, it formed a bridge between your laptop and your favorite professional mic, such as U87, TLM 103, and MKH-416. 

With the next generation MicPort Pro CEntrance raised the bar on portable recording. The new MicPort Pro has a built-in rechargeable battery and records to phones and tablets in addition to laptops and desktop computers. All units include a limiter. With a host of professional features, MicPort Pro is versatile, easy to use and travel-friendly.
