Product Description

Voice Tracker II Array Microphone: The Missing Piece to Your USB Echo Cancellation Puzzle

Ever feel like Microsoft Lync or Adobe Connect are just one teensy step away from being as good as more expensive and complicated conferencing tools?

Prepare to take a giant leap. The Voice Tracker II Array Microphone turns Lync,  Adobe Connect and other affordable software and hardware based video conferencing systems into a quality audio capture system.

Echo Cancellation

Connect the Voice Tracker II Array Microphone to your PC-based VoIP software and no more need for headphones—any near-end talkers on the fringes of the room will come in loud and clear (even the soft talkers). The mic’s acoustic echo cancellation algorithm even eliminates that echo effect far-end talkers sometimes hear.  With this anti-echo technology, combined with a hefty dose of internal DSP, the Voice Tracker II can pick up talkers throughout the entire room.

Portable and Powered

Big in sound yet small in size, Voice Tracker II goes anywhere. It doesn’t even need a wall power converter—just plug it in through the USB connection. That means no need for adapters in other countries.

Talker Stalker

Voice Tracker II steers a listening beam to all active talkers, keeping tabs on them. When they speak, the mic can send that location info to an automatic camera or robot, alerting them to turn the lens on the talker. It’s like having an invisible director in a control booth running your show.

Full-Duplex, Fraction of the Cost

Voice Tracker II’s anti-echo tech, internal DSP, small size and voice tracking make it a contender with conventional conferencing systems. It’s the perfect choice for full-duplex VoIP-based conferencing at a fraction of the cost.
