AVB Output

AVB Output objects provide support for explicit AVB audio reception from IEEE 1722.1 compatible third-party devices.

AVB blocks can be allocated to a Tesira SERVER, SERVER IO and TesiraFORTÉ device, Audio Expanders (EX-MOD, EX-AEC, EX-IN, EX-OUT, EX-IO and Lab.gruppen Amplifier) do not support AVB blocks.

Up to sixteen Tesira AVB Output blocks can be placed into each SERVER, SERVER IO or TesiraFORTÉ device. Review the AVB Network Considerations sections for AVB stream and channel bandwidth information.  

A requirement of 1722.1 is that the talker and listener streams must have the same channel count. If the channel counts differ, Audio streams will not flow correctly.

When this object type is selected from the Object Toolbar, an AVB Output Initialization dialog window is displayed.

Name	Description	Range
Channel Count	Determines the number of channels in the block. If Custom is selected from the drop-down list, any number of channels from 1 to 60 can be specified.	1-60
Network	Allows the required Media Network Setup to be specified

Channel Indicators and controls

Name	Description	Range
Mute	turns the input signal on/off.	On or Off
Level	adjusts the relative input volume.	-100 to +12
Invert	adjusts the polarity of the input signal.	0° or 180°

AVB 1722.1 Stream

Name	Description
Name	allows the AVB stream name to be defined. The stream name must be unique, and must not be left blank. When a stream name is entered that is not unique, an error message is displayed.
Active	is used to indicate whether the stream is actively passing audio or not. In cases where audio is expected but not present, this can trigger a fault condition based on the setting for the ‘Fault when inactive’ flag in DSP Properties.
