iAudioInterface2 has an XLR phantom-powered microphone input, which will work with any microphone which is powered by 48V phantom power. It does not ship with a microphone. The phantom power meets all standards for voltage and current, and so will power even demanding microphones, such as some Earthworks models.

The phantom power may also be disabled, so even non-phantom power dynamic mics may be used.

There are also 9 available hardware gain ranges, supplying up to 50 dB of gain.

So, if you already own a measurement microphone, in most cases you will be able to use it with iAudioInterface. If you don’t have a microphone, you do have a lot of options. One mic that won’t work, however, is the original iAudioInterface mic, which uses bias power only and is unbalanced. Also, the TerraSonde Plus / Sencore SP 295 AudioToolbox mic will not work, for similar reasons. The Sencore SP395 / TerraSonde ATB-3, and Sencore 495 / TerraSonde ATB-3C mics will work fine. Also, many of the B&K measurement mics require special power supplies.

We sell several excellent microphones that you can order a mic with your iAI2. Check our online store in the US or with your distributor in other countries to see what they offer.
