Mini Lav Mac for Voice and Acoustic Instruments!

Your first glance at the Audio-Technica AT831b may make you think that this little cardioid condenser lavalier microphone is only suited for the voice — but, don't let your eyes be the judge. Many musicians and engineers are finding out just how versatile the Audio-Technica AT831b really is. If you have, say, a straight-up acoustic guitar — without electronics — you can easily use the AT831b and an included clip, to achieve a crisp, full-sounding amplified voice. You can also grab other notoriously hard-to-mic instruments and simply clip on the Audio-Technica AT831b.

Audio-Technica AT831b Condenser Lavalier Microphone at a Glance:
    • Excels on vocals, but is also a stand-out choice on acoustic guitar
    • Includes a bunch of accessories — windscreen, clip, instrument adapter, and more

Excels on vocals, but is also a stand-out choice on acoustic guitar
Audio-Technica classifies their AT831b as a lavalier microphone, but if there were a "seriously versatile" category, the AT831b would surely fit into it. And, it's for that reason that the AT831b is such a good fit for any venue — be it a school, a church, or a stage — looking to get the most out of their locker of microphones. You can use the AT831b on vocals, for excellent pickup. Yet, using an included instrument adapter clip, you can just as easily ust the AT831b to pick up acoustic guitars or other difficult-to-mic instruments. You'll be surprised by how full sounding the AT831b is — plus, with its cardioid pickup pattern, the AT831b can excel in situations where feedback or room noise tend to be problems.

Includes a bunch of accessories — windscreen, clip, instrument adapter, and more
You get a load of accessories with your AT831b, to make it perfect to nearly every miking situation. The AT831b condenser lavalier microphone comes with an attached AT8530 power module with a battery, and can use either 1.5V AA batteries or 9-52V phantom power. It also comes with the AT8116 foam windscreen to help you protect against wind noise outside. For using as a old school lavalier microphone, just use the included AT8417 clothing clip. Or, if you're using the AT831b to microphone instruments, you can use the AT8444 instrument adapter, also included. Finally, the AT831b comes with a protective case for traveling with and storing your microphone.
