The Voice Tracker I can be used since the AEC in Skype for Business is robust enough to adjust to the Voice Tracker’s listening beam as it moves rapidly from talker to talker. The Voice Tracker picks up the talkers around the monitor, and ranges of 25 feet or more, and with an extremely wide field of view. The team then stands around the monitor to engage in their conversation. The participants bring along their laptop, place it on the shelf, and connect it for the meeting. A loudspeaker bar is mounted below the display.Īlso below the display is a shelf to hold a laptop. The Voice Tracker is mounted, together with a camera, on top of a large display monitor. See the photo below.īob Using Voice Tracker Array microphones in open area Huddle RoomsĪ well known eastern insurance company is employing Voice Tracker I microphones throughout cubicle areas to facilitate Skype for Business based collaboration meetings. You can then connect the speaker jack from the TRRS splitter directly to the loudspeaker. This reduces the number of cable connections (clutter). If you are using Zoom or Skype for Business as the VoIP App, they have good AECs, so the AEC in the Voice Tracker II is not required. Note the thicker 3.5 cable to the middle jack on the VT II (the audio out jack). Then run a VoIP app on the iPhone or iPad. Provide power to the Voice Tracker II from USB battery, or a USB wall power supply. Connect the speaker jack from the TRRS splitter to the ref in jack on the Voice Tracker II, and connect an external powered computer loudspeaker to the speaker out jack on the Voice Tracker II. When the Voice Tracker is connected thru the TRRS splitter and impedance adapter, you can hear the improved pickup range: īecause the Voice Tracker II has built in acoustic echo cancellation, it can be used with iPads or iPhones for inexpensive conferencing. The output impedance of the Voice Tracker II is higher than that, so an adapter is needed in the 3.5mm cable to reduce the output impedance to below 10K. If the output impedance of the mic in higher than that, the iPhone/iPad will default to their internal mic. These devices require an input impedance of less than 10Kohm. Second, the output impedance of the Voice Tracker II must be adjusted to match the expectation of the iPad/iPhone. Such splitters are readily available commercially. This is connected to the 3.5mm jack on the iPad or iPhone and creates separate 3.5mm connections for the mic and loudspeaker.
