The digital AES3 model is composed of 4 AES3 inputs and outputs. The inputs and outputs can be wired with the DB25 connectors or the RJ45 connectors. The top DB25 connector is for the inputs while the bottom DB25 is for outputs. The top row of RJ45 is for inputs while the bottom is for outputs.
Power to the model is either with an AC power input or a PoE+ at the top network connection. The bottom network connection is a non PoE+ interface used for management or streaming redundancy.
Setup
Chapter Two describes how to assign an IP address to the xNode2. Chapter Three, In-Depth, describes the various pages available in the xNode2. Once you have your inputs inserted into the connector of choice, DB25 or RJ45, login to the HTML interface and select the I/O link. Give each AoIP Sender a name that describes the audio source. This becomes useful when browsing the network. Assign any gain needed for the source or leave at the default unity gain of 0. Each sender on the network needs a unique channel between 1 and 32767. A common model is to use the last octet of the IP address as a preamble to the channel number. For example, and address of 192.168.2.207 could utilize the channels 2071 - 2074. Figure out a scheme that works for your facility deployment. Define if the stream shall be a Live Stereo or Standard Stereo. Determine if your facility has a common sync for the AES3 equipment or to use the sample rate conversion in the xNode2. Enabling SRC allows for not needing all the AES3 equipment to be in sync. Press the Save button and now the xNode2 is streaming AoIP into the network.
The AoIP Receivers portion of the I/O page is similar in that the name field is useful for documenting what is connected to the xNode2 and thus receiving the audio in the AoIP stream. Define any gain values needed for each receiver or leave at the default unity gain. Use the channel picker to browse the network for the desired stream or type it in directly into the channel field if the channel number is known. Does the device receiving the AES3 signal need something other than 48kHz and will it sample rate convert or needs a common sync. If the SRC is turned off, the AES3 signal will match the native 48Khz of the xNode2. If you need the AES3 signal to be sync’d to another source, that source must be an input into the xNode2 and that input would be selected at the top right of the Receivers section. Press the Save button and now the devices connected to the xNode2 are receiving AES3 audio.
