AV2USB AV2USB AVB to USB audio interface User Manual Revision Description Date V1.
AV2USB Description The AV2USB is a bridging interface allowing any computer to act as an Audio Video Bridging (AVB) endpoint. In other words giving the ability to stream multiple channels of uncompressed, low latency and tightly synchronized audio over Ethernet networks. By combining asynchronous USB audio to the latest Audio Video Bridging (AVB) standards, high end streaming of AV content is finally a reality.

Use this connector if you want to power the AV2USB from a PoE AVB switch Network connection#2 on RJ45. Redundant connection for network. USB Audio 2.0 on miniUSB connector Rear panel description 1 1. DC input for device powering. Requires a stable +5VDC supply supplied with the product 1.3 1.3.
AV2USB o o o o 2 2.1 Talker/Listener: AVB endpoint that is both transmitting and receiving. All AVB endpoints used on Dana series are by default Talker/Listener devices. Precision Time Protocol (PTP): Allows devices on the network to get a notion of global time in the effort to synchronize with each other. PTP component in each AVB module can act as a Grand Master (providing clock) or as a slave (receiving clock).

AV2USB 3.1.3 Setup the driver package Click on the setup.exe application to start the installation process. After clicking next, the setup wizard will check your system capabilities. If you didn’t connect the USB audio cable and provided power to the AV2USB unit, you will receive the follow message. Make sure you connect both the USB cable and +5V external DC power to the unit. Next step is to choose a location on your harddrive for the installation.
AV2USB .Click on Continue Anyway at the warning about driver certificate. A successful installation will show the following dialog box.
AV2USB Click on Install the software automatically. Click on “Continue Anyway” to the warning message about driver signing.

AV2USB 3.2 3.2.1 AV2USB USB Audio driver configuration Driver general info This panel is just a general information panel with the driver version. 3.2.2 Buffer settings The buffer setting is meant for those looking to optimize the buffering and latency settings of the interface. Note that change of these settings may result in unstable operation since such modifications are PC resource-dependant.
AV2USB As displayed on the screenshot, the AV2USB is currently locked at 48kHZ sample rate which is a common sample rate for most AVB products currently shipping on the market. 3.2.
AV2USB 3.2.7 Stream formats Since the AV2USB is always defaulted to 8x IN, 8 x OUT, no configuration is available from the following page. 3.3 Mac OSx configuration Mac OSx has native support for USB Audio class 2.0 device and therefore doesn’t require any drivers. The device will automatically be detected as a compliant multichannel USB audio interface. See below some screenshot of the interface. 3.3.
AV2USB To enable this sound card as a default output device, you need to right click on the AV2USB interface to tick “Use this device for sound output”. It will default the AV2USB as the default output device for all your media player applications. 3.3.2 Speaker output for default output channel Being a multichannel device, one can easily configure the AV2USB for a 7.1 application if I2S is being used to feed a multichannel DAC. Here are the 2 most common configurations.
AV2USB 7.1 multichannel configuration using the I2S outputs Similar to before but this time, select the 7.1 Surround configuration from the drop down menu. You then just need to assign the I2S channels as per your DAC configuration.
AV2USB 4 AVB Streamer Tools setup guide The AVB Streamer tool is the application used to configure the AVB network and stream routing. It is based on the Adobe Air environment and currently only operates on PC environments. See below system requirements Software Microsoft• ® Windows® Vista® SP1/ XP pro SP2 Microsoft• ® .NET framework v3.
AV2USB 4.1 User interface overview of the AVB Streamer toolbox AV2USB configuration software provides a simple user interface for configuration of the AVB A Device tree on the left side lists all discovered AVB devices on the network A center section tabbed based structure allows access to the various sections of the user interface Tabbed Structure Device info: Provides overall view of the current settings of AV2USB device including the model number, firmware version, IP settings.
AV2USB 4.2.1.2 Static IP mode The AVStreamer toolbox allow for setting up the device as DHCP/AutoIP (i.e. automatic addressing) or Static IP addressing. Click on the SET button below to access the IP settings page. By default, all units ship with DHCP/AutoIP mode and is the mode we recommend for all operation. If using static, insure that you’re aware of what you’re doing else you may not be able to correctly configure the unit.
AV2USB To select one listener for configuration, drag & drop action as shown by green arrow To select one Talker for configuration, drag & drop action as shown by green arrow 2 simple sections: Talkers (source) on the left, Listeners (destination) on the right. Select one Talker (i.e. Source) from the Talker list and drag&drop it in the “Drop Talker Here” box. Repeat the same step for the Listener side (i.e. destination). Let’s use the case where the AV2USB is a talker (i.e.
AV2USB Although the user interface will automatically pack up the talker channel in consecutive order on the listener side, audio channels can be re-arranged. Using the Up & Down buttons, one can re-organize the order of channels on the listener side as you wish. The final step is to click on the BUILD Stream button at the center of the interface. A confirmation message will appear with the Stream ID information. 4.2.2.
AV2USB The panel is now reset and ready to be configured again. 5 Virtual Stream – AVB configuration for 3rd party AVB products Since the AVBStreamer v1.4, designers can setup streams with a 3rd party AVB product providing you know the 64bit unique stream ID you would like to “subscribe” to.
AV2USB 6.2.1 Foobar (Open Source) Step 1 – Configure the target sample rate from the DSP manager of the Resampler plug-in. Step 2 – Configure the ASIO routing from the playback - > Output section. The Audio channels will appear as 4 pairs of 2ch. Step 3 – Make sure to select the correct interface from the drop down list.
