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.
Diagram: The Rear Panel Connections:
1) 12 VDC, 1.0 Amp Power Connector: The 5.5mm OD and 2.5mm ID coaxial power connector should be
plugged into the PowerRite power supply provided by Vaddio. Use of any unauthorized power supplies will
void any and all warranties.

Appendix A.
3) Settings (8-Position Dip Switch): The eight position dip switch is used for system configuration of the
EasyTalk Wireless Receiver (see next page for table).
4) GPIO Port: The GPIO Port provides the ability to interface with
external control systems. Inputs are logic level low. The outputs
are open collectors.
5) USB Type B Connector: This connector is used to interface with the Host PC for soft-client codec type
applications.
6) Audio Outputs: There are two (2) Audio Outputs on the rear panel:
 Balanced Audio Output Jack: Balanced Line Level (on XLR - M connector) +4dBu
 Unbalanced Audio Output Jack: Unbalanced Line Level (on RCA-F connector) -10dbV
