Featuring a frequency range of 100 Hz to 11.3 kHz, the Voice Tracker II Array from Acoustic Magic is a mountable microphone designed not only for recording lectures (including any question-and-answer portions thereof), but for facilitating large-scale conference calls as well. It compounds upon the technology of its predecessor by implementing six separate microphones for its automatic vocal tracking technology. The device also offers an on-board acoustic echo cancellation algorithm for eliminating the faraway vocal redundancies often occurring in large conference calls. It's enabled for VoIP-based conferencing, and connects via USB to computers or wall-jacks (available separately). Position Lights A five-element green position light lets your know where the "listening beam" is pointing in real-time, allowing you to make sure you're getting signal from the right portions of the room. Noise Reduction & Echo Cancellation Noise reduction technology and automatic echo cancellation helps bring the voices of main speakers to the forefront without redundancies. The unit is particularly adept at mitigating stationary noise, such as that coming from fans. DB9 Connection The location of the speaker in relation to the Voice Tracker II can be pinpointed and represented digitally when plugging into its onboard DB9 jack. If echo cancellation is not required, you only need plug the unit into your computer via USB. In the box* Acoustic Magic Voice Tracker II Array Microphone Acoustic Magic Microphone Power Supply
