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 balan ced 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 ind ependent USB and analog gain stages. Gain structures can be co nfigured 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 system s.

 Optional Rack Mounting Kit: The ½-rack kit (PN: 998-6000-004) provides

a method for the EasyUSB AudioBRIDGE to be installed in a 1-RU space

within a rack. The Rack Kit includes two rack ears (one long and one short).

The rack ears are mounted on the sides of the AudioBRIDGE using the

existing screws included on the encl osure.

 Optional Under-Table Mounting Bracket: Fits Vaddio ½ rack enclosures and securely

mounts the AudioBRIDGE to the underside of the conference room table to remain close to

the PC used for the UC conferencing application (PN: 998-6000-00 5)

 USB 2.0 Extension Kit: An optional Active USB 2.0 Extension Cable extends the USB 2.0

connection between the AudioBRIDGE and the PC to 65.6’/20m (PN: 440-1005-020).

System Configuration and Programming

EasyUSB AudioBRIDGE

The EasyUSB AudioBRIDGE has an 8-position dip switch on the rear panel of the device for

allowing installers to customize product for the desired conferencing application. Available

configuration functions a re listed in the Table below. The “up” positi on on the dip switch repres ents

enable and the “down” po sition represents disable.

Table: EasyUSB Audi oBRIDGE Dip Switch Configuration Settings

Dip Switch Function Description

SW 1 HID Volume Lock HID Volume Lock disallows the Host PC from adjusting the line input and

line output gains on the AudioBRIDGE.

Down (disable) = PC can adjust line input and line output gains

Up (enable) = HID lock enabled and PC cannot control input and output

analog gains. Gain will be locked at current value when feature enabled.

** Requires a power cycle of AudioBRIDGE when changed**

SW 2 USB Terminal Type The USB Terminal Type defines the type of audio devic e connected to the

Host PC according to the USB 2.0 device specifications. Some software

applications (including Microsoft Lync) use this setting to modify PC’s audio

processing functions accordingly.

Down (type 405) = Echo Canceling Speakerphone USB Terminal Type

Up (type 403) = Non-Echo Canceling Speakerphone USB Terminal Type

** Requires a power cycle of AudioBRIDGE when changed**

SW 3 Input Attenuation Applies 6dB attenuation to the line input mix. The unbalanced input and

balanced input are automatically summed before sending to the USB TX

channel.

Down (Disable) = No line input attenuation is applied to mix

Up (enable) = 6dB attenuation is applied to the unbalanced and balanced

line input mix.

SW 4-7 Not Used Reserved for future features

SW 8 Firmware Update This switch places the AudioBRIDGE in firmware update mode allowing

integrators to upgrade the device using Vaddio software. When enabled,

the audio operations will be disabled during the firmware update procedure.

** Requires a power cycle of Audio BRIDGE to take affect**

Mixing Modes

The EasyUSB AudioBRIDGE supports a single mixing mode. The Unbalanced & Balanced Line Inputs will be

automatically summed and sent to the USB TX (Recording) channel on the PC. The USB RX (Playback) channel

from the PC will be routed to both the unbalanced and balanced line outputs of the AudioBRIDGE.

USB RX (Playback) Not Available X X

“X”- represents an internal cross-point within the matrix.

Advanced Audio Operational Functions

HID Volume Lock (Dip Switch 1): The HID Volume Lock fun ction can be used in appli cations where it is desirable

that the PC does not change analog gain settings on the AudioBRIDGE. When in locked mod e, the gain structures

between the AudioBRIDGE and the connected AV equipment (Room DSP) cannot be modified by the Host PC.

This can be desirable to maintain constant cross-point levels on a room’s mixer that is combining multiple audio

sources preventing the USB audio levels over-riding other sources in the mix.

USB Terminal Type (Dip Switch 2): The USB Terminal Type is useful for deployments using Microsoft Lync.

Microsoft Lync uses the terminal type to automatically enable or disable the software acoustical ech o cancellation.

There recommended setti ngs for Terminal Type are:

 Type 405: Set AudioBRIDGE to Type 405 if the connected professional audio equipment has built in echo

cancellation. Microsoft Lync will disable its internal echo cancellation. This typically will yield better audio

performance in terms of duplex operatio n.

 Type 403: Set AudioBRIDGE to Type 403 if the connected professional au dio equipment doe s not have built-

in echo cancellation. Microsoft Lync will enable its internal echo cancellation. Note that Microsoft Lync is a

single echo canceler. Summing multiple microphones into the software based echo canceler can yield poor

performance depending upon acoustical characteristics of the room.

Input Attenuation (Dip Switch 3): Enabling (up ) dip switch 3 will automatically apply 6dB attenuation to the audi o

mix being sent the USB TX (Record) cha nnel. Note that the AudioBRIDGE will sum the Un balanced Line Input and

the Balanced Line Input. If both inputs are active in the application, enabling the 6dB attenuation will provide a

higher dynamic range.

User Operations

Connecting to a PC

The EasyUSB AudioBRIDGE is connected to the PC with a simple USB cable. O nce connected, the PC’s operating

system will recognize the AudioBRIDGE as a USB sound device. The sound device will be identified as an echo

canceling speakerphone (or non-echo canceling speakerphone) with one playback channel (speaker) and one

recording channel (microp hone). The AudioBRIDGE is designed as a USB Audio Class (UAC) device. There are

no requirements for pesky custom drivers on the Host PC for operations.

To use the AudioBRIDGE as the PC sound d evice, t he u ser will b e required to sele ct it as th e default audi o device

within the sound manager in the operating system. Th e example below shows the selection proces s for a PC using

Windows 7.

STEP 1: Go to the Windows Control Panel and sele ct the Sound icon

◄

EasyUSB AudioBRIDGE

Easy USB AudioBRIDGE - Document Number 342-0769 Rev B Page 9 of 16

STEP 2: Go to the Playback Tab on Sound pop-up window. Select the EasyUSB device in the list. Press the

arrow on the “Set Default “button at the bottom. Select the “Default Communication Device” in the list. Windows

7 allows the user to set the sound device as either the default sound device or the default communication device.

If set as the default communication device all UC soft-client applications will automatically be routed to this sound

device. The recommendation is to configure the AudioBRIDGE as the default communication device. A handset

icon represents this selection in the list.

STEP 3: Move to the Recording Tab of the Sound pop-up window. Select the AudioBRIDGE within the list and

click the Set Default button. This sets the EasyUSB AudioBRIDGE as the default communication device for the

microphone.

Note that some UC soft clients will automatically store the Operating System sound device

configurations within the application. Th is function will automatically reconfigure the sound d evice when

application is launched.

AudioBRIDGE - Document Number 342-0769 Rev B Page 10 of 16

The Mixer in the PC

The AudioBRIDGE volume and mute audio controls are mapped to the operating system sound device controls

used by the software application (when HID Lock is not enabled). This allows the software application to change

the loudspeaker volume o r mute microp hones fro m th e PC (if supported by the software appli cation). An ex ample

of typical speaker audio controls from the operating system is depicted below.

A Note about Working with Unified Communications Soft Clients

As the examples with Skype and Microsoft Lync indicate, the soft clients essentially all work the same way.

However, each of them has their own way of getting to the proverbial finish line. The language and nomenclature

is different, the file systems and drop down menu s differ, but the underlying objective is to assign the Audi oBRIDGE

the speaker and the mic for the PC to use as I/O for the soft client application.

As more examples are gathered, each of these 1-2 page TechNotes will be posted on the Vaddio website.

The most important thing about interoperability with PCs and soft clients is to involve the IT department

and Network Administrators that are responsible for their company’s lifeblood (or network). In all cases

it is important to work with personnel within the IT department to ensure a successful deployment of the

EasyUSB Tools offered by Vaddio. While these products are easy to work with, there are always a

handful of “gotchas” that baffle and confo und even the brightest amateur computer guys.

Firmware Updates

The EasyUSB AudioBRIDGE can be upgraded in the field with the use of the Vaddio Loader software application.

The processes for firmware updates are as follows:

STEP 1: If you are uncertain about updating or upgrading the equipment, please contact Vaddio

Technical Support first. There is a possibility that any device can be turned into a brick, so give Tech

Support a call first to get the dos and don’ts of updating.

STEP 2: Set Dip Switch 8 up on the back of the EasyUSB AudioBRIDGE. Power cycle the device. Connect to

the RS-232 port on the AudioBRIDGE. Launch the newest available Vaddio Loader application on the PC (not a

MAC) and set the COM port to the associated PC conn ection. Select the AudioBRIDGE in the drop down li st at the

top of the page. Select the load file from your local or network folders. Press the Start button on the loader. This

will begin the firmware update transfer to the unit. A progress bar will indicate when the transfer is complete.

While updating a device, NEVER interrupt a transfer, even if it looks like it isn’t doing anything. Interrupting a

transfer may “brick” the unit and it might require emergency return to factory surgery.

interface can be used interactively with a serial terminal emulator such as AMX or Crestron Control systems. The

command echo and prompt can be enabled or disabled with the 6121 command. When enabled, command input

to the EasyUSB AudioBRIDGE are echoed back, and a ‘>’ prompt character is automatically output on a carriage

return. When the command echo and p r ompt are disabled, the echo and prompt characters are suppressed.

For all commands, the termination character is a carriage return (hex 0D). Responses from the EasyUSB

AudioBRIDGE will end with a carria ge return followed by a line feed (hex 0A).

The baud rate of the Easy USB AudioBRIDGE is 38,400 with following serial format:

 Stop Bit: 1

 Data: 8 bit

 Parity: None

 Flow: None

The EasyUSB AudioBRIDGE protocol is based upon a “Set” and “Get” scheme. Set commands automatically

return an acknowledgement upon exec ution.

The “Get” command returns a string representing the current value of the queried setting.

The “Set” commands return one of three responses:

 OK (4100)

 Unknown command (4199)

 Bad parameter (4198).

“Get” commands return a response string indicating the command being responded to and the data requested.

The format of a “Get” response is a 4-digit response code, a space, and a two-digit hex value. Examples of

command usage are:

 Set Command Usage: > 6101 00 <carriage return> (unmute the microphones)

 Response: > 4100 00 (Microphone not muted)

 Get Command Usage:> 5101 <carriage return> (queries current mute state)

 Response: >4101 00 (Microphone not muted)
