Easy USB AudioBRIDGE - Document Number 342-0769 Rev B Page 3 of 16
Overview
The EasyUSB AudioBRIDGE is an elegant
solution to enable existing professional
audio equipment to go digital by converting
the analog audio signals to USB 2.0 for use
with Unified Communication soft clients like
Microsoft Lync, Cisco Jabber, Google+
WebEx, GoToMeeting and more!
Professional audio equipment can connect to the AudioBRIDGE with balanced line level inputs and outputs on a
3-pin Euro terminal block connector or unbalanced, consumer level inputs and outputs on RCA connectors. The
AudioBRIDGE converts the analog audio to a USB microphone and loudspeaker channel for connection to a PC
application.
The AudioBRIDGE is optimized for use with many UC clients including Microsoft Lync. A unique feature of the
AudioBRIDGE is the user configuration of USB terminal type. The AudioBRIDGE is configurable as a USB
speakerphone (Type 403) or a USB echo canceling speakerphone (Type 405). Use Type 405 when connecting
to professional audio conferencing DSP mixers with echo cancellation. Use Type 403 when connecting to audio
equipment that does not have internal echo cancellation. This feature improves performance with Microsoft Lync
and other soft client’s internal echo canceling routines.
The AudioBRIDGE includes independent USB and analog gain stages. Gain structures can be configured
between the pro audio equipment without being impacted by PC volume controls. Additionally, the AudioBRIDGE
even includes a serial control (RS-232) port for use with external control systems.
While the EasyUSB AudioBRIDGE is a simple idea, execution of the idea is one of the most important aspects of
selecting an analog audio to USB 2.0 converter. This solution offers many desirable features specifically included
to perform flawlessly for mission critical UC applications using new or existing audio systems.
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. Do not connect Ethernet or
Power over Ethernet (PoE) cables directly to the RJ-45 ports on the device as damage may result.
Save These Instructions:
The information contained in this manual will help you install and operate your product. If these instructions are
misplaced, Vaddio keeps copies of Specifications, Installation and User Guides and most pertinent product
drawings for the Vaddio product line on the Vaddio website. These documents can be downloaded from
www.vaddio.com free of charge.
Use only the power supply provided with the system. Use of any unauthorized
or extended power supply will void any and all warranties.
Please do not use “pass-thru” type RJ-45 connectors. These pass-thru type connectors do not work
well for professional installations and can be the cause of intermittent connections which can result in
the RS-232 control line failing and locking up. For best results please use standard RJ-45 connectors
and test all cables for proper pin-outs prior to use.
