The Voice Tracker III is ideal for our array microphone’s traditional applications of lecture and meeting recording, but improvements in VoIP products open the door for additional use in video conferencing and distance learning.

State of the art VoIP products like Zoom and Skype have improved AEC capability, so the Voice Tracker III doesn’t need its own AEC and consequently fills the need for an affordable yet high performance conferencing array microphone. Priced at $470, the Voice Tracker III costs much less than competitive array mics, making it practical for multiroom installations.

We opted to make the Voice Tracker III simple and easy to use. Just connect it to a wall power source and your computer thru a 3.5mm or USB connection and you are done. No multiple beam set up is required. The single “Listening Beam” automatically and electronically steers to the active talker. It is truly plug and play.

The decision not to add peripherals such as a camera or loudspeaker in our design enables the user to be free to choose best in class products, or to take advantage of existing equipment.

Multiple Voice Tracker III array microphones can be combined using 3.5mm Ys or Mixers. Use with High Performance mixers will lead to amazing room coverage and sound quality.

The Voice Tracker III can sit on a table or podium, but it also comes with a ceiling/wall mount. Because of its long pickup range, ceiling or wall mounting will work well and removes room clutter.

The Voice Tracker III is 22 inches long, 3 inches high (without the feet) and 2 inches thick.
