Features & Specifications

The MicPort Pro was created with the mobile artist in mind, featuring an impressive and fully loaded feature set.

Features

  • 24-bit/96kHz performance
  • 48V phantom power
  • USB bus-powered
  • Loud stereo headphone output
  • 6’ (1.83m) USB cable included
  • Microphone gain knob
  • Headphone volume knob
  • Rugged, anodized aluminum chassis
  • Windows XP and Vista compatible
  • Mac OS X 10.5 compatible
  • USB 1.1 and USB 2.0 connectivity

What I'd really like to look at that isn't a feature of the MicPort Pro is Linux support. Since the MicPort Pro is supposed to be recognized in both Mac OS X and Windows without having to install a driver, I wonder if it will work the same in Linux.

Before testing this thought, let's look at the specifications of the unit and see what powers the capabilities of the unit.

Phantom power sends voltage from the MicPort Pro (or other preamp-like devices) to the microphone, often giving the microphone a little more power, or enabling it to pick up a little more sound. Phantom power is mostly used with condenser microphones, and not the typical dynamic microphones such as the one I'll be using later to test the device. As the name suggests, however, the power is rather invisible and shouldn't damage a microphone not supporting it.
