One aspect of the ATR2100-USB that either serves as a bonus or detriment (in majority of cases a bonus) is that it’s frequency response is between 50 – 15,000 Hz. That means that very low frequencies below 50Hz (often lower than the human voice is capable of) are not picked up.

This can save plenty of time trying to clean up audio that his picked up rumbling background noises that can really ruin a recording. This also means, however, that the uses of the ATR2100-USB may be restricted to instruments that sit higher up in frequency.

Apart from the USB and XLR inputs, the bottom of the microphone features a volume control and a low latency headphone input. The side of the microphone has a simple on off switch with a bright blue LED light indicating when it is turned on. So the features are very simple and straightforward requiring zero learning curve; simply plug ’n play into any recording device without the need for drivers or tech jargon.

Included with the Audio-Technica ATR2100-USB is a 10’ XLR cable and a mini tripod stand suitable for desktop use.
