If you need a USB mic for recording podcasts, streaming online, or tracking vocal parts, the Mackie EM-91CU offers a quality sound for just this purpose. It also delivers a reliable and rugged design at a reasonable price, making it both a suitable entry-level product and a solid choice to augment a podcaster's existing collection.

With its cardioid polar pattern, the mic rejects sound coming from behind the capsule to tamp down on pesky room ambience; this is a plus for many people who podcast from their home. All the accoutrements you need to get started are included. Mount the mic in the supplied shockmount, plug the included USB cable to your computer, and you're good to go.

Get started right away, as this mic works directly with your computer. No separate interface or preamp is required.
Cardioid Polar Pattern for the Untreated Room
The microphone makes use of a directional cardioid polar pattern to minimize off-axis sound. This polar pattern naturally, yet effectively tamps down room tone and focuses the audio capture on what's directly in front of the mic, so everyone can clearly hear your voice.
Broadcast-Quality Audio Capture
The mic records audio at sample rates and resolutions up to 16-bit / 48 kHz, giving you the broadcast standard for media playback.
Handy Hardware Included
With an included shockmount and USB cable, you can get up and running right away. Simply place the mic in the mount and run the USB cable from the mic into your computer.
