Overview:
The optional EasyTalk Wireless Audio Interface System
expands audio capabilities for the AutoTrak 2.0
Automated camera tracking system. Key features of the
EasyTalk Wireless Audio Interface include:
 HD Wireless Link with Adaptive Frequency Hopping (AFH) for interference free operation.
 USB Audio Output on Wireless Audio Interface allowing connection to a PC for Skype Applications.
 Works in conjunction with the integrated unidirectional microphone in AutoTrak 2.0 IR Lanyard and with the
rechargeable AutoTrak 2.0 Belt Pack transmitter that features a lithium-ion battery pack for extended hours of
operation.
The improved AutoTrak 2.0 Wireless Audio Interface is a wireless receiver that works in combination with the
AutoTrak 2.0 IR Lanyard and Belt Pack. The AutoTrak 2.0 IR Lanyard’s central medallion contains a high quality
unidirectional microphone and the belt pack uses an HD wireless transmitter with AFH technology that can be
turned on or off. The presenter’s speech is sent to the optional EasyTALK Wireless Audio Interface specifically
designed for use with the AutoTrak 2.0 System.
The receiver has a balanced or unbalanced line level output for connection to an amplifier, videoconferencing
codec or other room A/V equipment. In addition, the receiver has a USB audio output that can be directly
connected to a PC emulating a microphone and speaker device for use with Unified Communication clients such
as Skype, Microsoft Lync, Google Talk, Jabber and others. Front panel controls allow the user to mute or adjust
output volume level. The back-panel GPIO is used for volume and mute functions that can be wired to external
control systems.
The Belt Pack, which is part of the AutoTrak 2.0 system, includes the 2.4 GHZ frequency hopping radio capable
of transmitting full spectrum audio (20HZ to 20KHZ). Advanced radio protocols such as adaptive frequency
hopping and forward error correction ensures reliable communication and coexistence with other devices in the
band. The Belt Pack includes a rechargeable lithium-ion battery pack allowing extended operations. Charging is
accomplished with a micro-USB power supply or by simply plugging it directly into a USB port on a PC.
The AutoTrak 2.0 Wireless Audio Interface incorporates user selectable digital signal processing (DSP) functions
to meet application needs associated with the classroom. Functions include Automatic Gain Control, Speaker
Equalization, Compressor, and Microphone Filtering. Collectively, the AutoTrak Wireless Audio Interface System
adds pristine sound quality to the Vaddio AutoTrak 2.0 Camera Tracking System assuring the Instructor’s speech
is heard by all students locally or in remote classrooms.
