What Can You Do with the ATR2100 Microphone?

Audio-Technica ATR2100-USB Microphone Review

The ATR2100 may one an entry-level microphone but it sure packs a punch with the applications you can use it.

Home Studio Recording

The ATR2100 can be plugged directly into a computer or desktop with a USB port. With this connective type, this microphone is perfect for home studio recording where your equipment will most likely be limited to a computer or laptop. Not to mention that the ATR2100 is compatible with Mac and Windows so you can plug directly the mic into your devices so you can start podcasting or recording right away.

While the ATR2100 is a handheld microphone, the kit includes a mic holder and stand. This allows you to use the ATR2100 on your desk. With the included stand, you’ll be sure that the ATR2100 will stay still when you conduct a Skype call or record a podcast.

Live Stage Performance

As the ATR2100 also has an XLR output, connecting this microphone to a sound system or sound box is possible. With that said, the ATR2100 can be used on the stage for a live performance. The kit also includes XLR cables making it easier for room and stage setup. However, you may need to purchase a separate microphone stand for stage applications as the included accessory in the kit is too small for this use.

This microphone also sounds great for live stage applications thanks to its smooth, extended frequency response and cardioid polar pattern. One can hear the user clearly as the mic can reject unwanted sounds from the sides.

Voice Recording

When it comes to vocal applications, the ATR2100 can deliver. With the built-in headphone jack, the user can easily monitor oneself from the microphone. This feature also allows a user to test any pair of headphones directly from the ATR2100 by listening to them speak to the mic.

The microphone also has easy-to-use controls found on the bottom, which allows a user to easily adjust headphone and mic volumes on the spot. This makes the ATR2100 an ideal mic to use for podcasts, voice-overs, and speech applications wherein you would need to listen and monitor the input. Just make sure to use a pop filter and shock mount for maximum audio quality.
