EasyTalk Wireless Mic
Overview:
The EasyTalk Wireless USB Mic System
expands audio capabilities for live voice
reinforcement with its analog outputs or lecture
capture with its USB 2.0 digital audio output
plugged directly into a computer. Key features of
the EasyTalk Wireless Audio Interface include:
HD Wireless Link with Adaptive Frequency Hopping (AFH) for interference free operation.
USB Audio Output allowing connection to a PC for UC Soft-client Applications or Lecture Capture systems.
Rechargeable Belt Pack transmitter that features a lithium-ion battery pack for extended hours of operation.
The system consists of a Belt Pack Transmitter, Lavalier Microphone and Wireless Receiver. The EasyTalk
Wireless Receiver works in conjunction with the Belt Pack Transmitter and Lavalier Mic worn by the presenter to
send the presenter’s speech to the room’s audio reinforcement, system conferencing system or lecture recording
software. The wireless link uses Adaptive Frequency Hopping (AFH) technology supporting the transmission of
full bandwidth audio digitally to the receiver.
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®, Jabber®, Microsoft Lync® or Lecture Capture Systems like Panopto®, Tegrity® and others. Both the
USB audio and the analog audio can be used simultaneously. 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 houses 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 EasyTalk Wireless USB Mic System incorporates user selectable digital signal processing (DSP) functions to
meet application requirements associated with the room. Functions include Automatic Gain Control, Speaker
Equalization, Compressor, and Microphone Filtering. Collectively, the EasyTalk Wireless USB Mic System adds
pristine sound quality to any audio or recording system.
Intended Use:
Before operating the device, please read the entire manual thoroughly. The system was designed, built and
tested for use indoors, and with the provided power supply and cabling. The use of a power supply other than the
one provided or outdoor operation has not been tested and could damage the device and/or create a potentially
unsafe operating condition
Important Safeguards:
Read and understand all instructions before using. Do not operate any device if it has been dropped or damaged.
In this case, a Vaddio technician must examine the product before operating. To reduce the risk of electric shock,
do not immerse in water or other liquids and avoid extremely humid conditions.
Use only the power supply provided with the system. Use of any unauthorized power
supply or extending the DC side of the power supplies will void any and all warranties.

Diagram: The Front Panel Controls:
1) Power ON/OFF: This switch turns the power for the EasyTalk Wireless Receiver on or off. When the
button’s blue LED is lit, the system is on ready for operation.
2) Pair: This button initiates the automatic pairing for the Belt Pack Radio Transmitter and the Wireless Audio
Receiver. Pairing is the matching of the same AFH sequence for both devices.
3) Mute: This control mutes (turns off) the audio outputs of the EasyTalk Wireless Receiver.

4) Volume: The + (plus) and – (minus) buttons are used to raise and lower the audio outputs (Balanced and
Unbalanced) from the EasyTalk Wireless Receiver.
5) Audio Level: This LED display ladder will indicate the relative audio level output (from all sources) of the
EasyTalk Wireless Receiver. The red line at the top of the display indicates clipping.
6) Radio, EQ Filter and Compressor Status LED’s:
Radio LED: Solid blue light indicates normal operation. Fast flashing indicates no link established with the
Belt Pack Wireless Microphone. Slow flashing indicates the Pairing cycle is in progress.
EQ Filter: Blue light on indicates the EQ Filter is turned on. Blue light off indicates the EQ Filter is off. When
EQ Filter is enabled, it helps increase speaker intelligibility for voice applications.
Compressor: Solid blue indicates that the Compressor is on. No light indicates that the Compressor is off.
The Compressor minimizes the potential of “clipping” by attenuating the audio signals that exceed the
maximum input.
7) Antenna: The antenna is tuned to receive 2.4 GHZ signals from the IR Lanyard Belt Pack Microphone.
Note: If the EasyTalk Wireless Receiver is installed deep inside a metal equipment rack or is surrounded by
other metal cased equipment, the antenna may need to be extended away from the rack to improve
reception.
