INSTRUCTIONS for the Voice Tracker
III array Microphone
Included Components
The Voice Tracker III comes with one 6 ft. audio cable, a
wall power adapter, and a ceiling/wall mount.
General Setup
Connect the power and audio cables to their appropriate
jacks on the back of the Voice Tracker
Figure 1). Plug the power adapter into a standard wall
outlet (note that the Voice Tracker III can ship with wall
power
adapters
for
plugs/voltage). The adapter supplies 6V DC power
(center pin positive) to the microphone.
Connect the other end of the audio cable to the
in"
input on your computer's sound card, or a USB
adapter like our part 102A, or an XLR adapter
transformer.
Note that Apple computers don't have mic level audio
jacks, so a USB adapter must be used. If your computer
only has a single TRRS jack, you may need a TRRS to
TRS (Mic & speaker) splitter/adapter.

input device for a variety of speech and multi-media
applications.
Many of the software packages which
utilize a speech input have setup tools, which allow you
to specify whether you are using the "mic In" connection
on your soundcard or the USB connection and to adjust
the sound level (volume) automatically. Please refer to
your specific application software for details. To adjust
the volume or input selection manually on a Windows
PC, see the Adjusting Your Soundcard section at the
end of these instructions.

Positioning
Aim the array in the direction of the desired talker(s).
When properly positioned, the talker will be able to see
all 5 green position indicators. The Voice Tracker III will
automatically scan its listening beam to the active talker.
Position Lights
The green position lights provide feedback on the
operation of the array. They indicate where the array's
listening beam is pointing. When the array recognizes a
relevant sound, one of the 5 lights will be illuminated.
The individual lights correspond to the range of potential
sound source locations.
directly in front of the array, the middle light will be
illuminated. If the talker is to one side, a light on that side
will turn on. If the talker moves across the field of view of
the array, the lights will track the talker's motion. When
two users are sharing the array, the light will indicate the
direction of the active talker. When a second talker
begins, the listening beam will move to him in 2 MSecs.
When there is no active talker, the lights may flicker as
