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.

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.

Step-by-Step Installation Instructions

EasyUSB AudioBRIDGE Installation

Position the EasyUSB AudioBRIDGE in a centralized location within the conference room, 6' (1.83m) from the PC. Follow steps below to install devices:

STEP 1: Plug in the 18 VDC power supply into the AudioBRIDGE power connector, but don't plug in the AC side yet.

STEP 2: Plug USB Type-B Male connector of the USB 2.0 cable into the AudioBRIDGE. Plug the Type-A Male connector into the PC USB port.

STEP 3: Connect the balanced line output on the room's DSP mixer into the balanced line input 3-pin phoenix-type wire terminals of the AudioBRIDGE. Connect the AudioBRIDGE's balanced line output cable on the 3-pin phoenix-type wire terminals and connect the other end of the cable to a line input on the room's DSP mixer.

NOTE: Maintain the positive, negative and ground terminals between the AudioBRIDGE and the room's Pro DSP mixer.

STEP 4: Set the dip switches to the appropriate USB Terminal mode (see table on the next page).

STEP 5: Plug in the AC for the AudioBRIDGE and a blue power LED will light on the front panel (a flashing blue LED indicates a fault condition). Once the AudioBRIDGE has power and is connected to the PC, the PC will recognize the AudioBRIDGE as both a USB Microphone and USB Speaker device in the operating system. With the PC connected to the network, launch the UC application.

Optional Accessories

The EasyUSB AudioBRIDGE has three optional accessory kits:

- Optional Rack Mounting Kit: The 12 -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 enclosure.

- Optional Under-Table Mounting Bracket: Fits Vaddio 12 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: 998-6000-005)

- 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 are listed in the Table below. The "up" position on the dip switch represents enable and the "down" position represents disable.

Table: EasyUSB AudioBRIDGE 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 device 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 AudioBRIDGE 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.

Table: AudioBRIDGE Routing Table

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 function can be used in applications where it is desirable that the PC does not change analog gain settings on the AudioBRIDGE. When in locked mode, 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 echo cancellation. There recommended settings 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 operation.
• Type 403: Set AudioBRIDGE to Type 403 if the connected professional audio equipment does 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 audio mix being sent the USB TX (Record) channel. Note that the AudioBRIDGE will sum the Unbalanced 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. Once 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 (microphone). 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 device, the user will be required to select it as the default audio device within the sound manager in the operating system. The example below shows the selection process for a PC using Windows 7.

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

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. This function will automatically reconfigure the sound device when application is launched.

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 or mute microphones from the PC (if supported by the software application). An example 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 menus differ, but the underlying objective is to assign the AudioBRIDGE 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 confound 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 connection. Select the AudioBRIDGE in the drop down list 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.

RS-232

The Control Adapter (998-1001-232)

RS-232 port to RJ-45 connector for external control systems and firmware updates over the serial port. This adapter has a DE-9-Female on one side and a RJ-45-Female on the other. The adapter takes the serial connections and routes them to the correct pins on the RJ-45.

Table: RS-232 DE-9 to RJ-45 Control Adapter Pins

DE-9-M Pin #	DE-9 Signals	RJ-45-FPin #	RJ-45 Signals
2	RXD	8	TXD
3 TXD	7	RXD (from TXD)
5	GND	6	GND

Note: The DE-9 connector, commonly called a DB-9, uses an E to sized shell, hence the DE designation. DB sized shells start at 25 pins.

Appendix 2: EasyUSB AudioBRIDGE Serial Commands (ASCII)

The EasyUSB AudioBRIDGE has an RS-232 command interface for configuration and real-time control. The 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 prompt 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 carriage return followed by a line feed (hex 0A).

The baud rate of the EasyUSB 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 execution.

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 (unmute the microphones)
• Response: >4100 00 (Microphone not muted)
• Get Command Usage:> 5101 (queries current mute state)
  • Response: >4101 00 (Microphone not muted)

Table: EasyUSB AudioBRIDGE Commands
