Enova Digital Media Switchers - Hardware Reference Manual
System Examples
The examples below show typical uses for the connection of Dante network(s) to an Enova DGX via the Dante Audio
Switching Boards. Enova DGX systems with Dante Audio Switching Boards are designed to route audio through the system
in three ways:
Daisy Chain Topology (Default)
Dante ASB Input and Output boards are connected one to the other through the system, reducing cable requirements.
Using the daisy chain topology requires changing the configuration in Dante Controller (Network Configuration Tab >
toggle Redundant/Switched) which is followed by a power cycle of the Dante ASBs.
An Ethernet cable from a network switch (connected to any other Dante devices) connects to the Dante Primary
Ethernet port on the Dante ASB Input board then a second run connects from the Dante Secondary Ethernet port on the
Dante ASB Input board to the Dante Primary Ethernet port on the Dante ASB Output board (FIG. 65).

down-mix
•
down-mix Input:
down-mix input fed from selectable embedded audio input from any Enova DGX
Input Board. down-mixed audio switchable to all embedded/Dante audio outputs.
•
down-mix input format support:
Dolby TrueHD, Dolby Digital, DTS-HD Master Audio, DTS, 2 Ch through 8
Ch L-PCM
Note: Only 2 channel L-PCM audio is supported by the Dante Audio Switching Output Board unless
down-mixing is employed. All other audio formats will be muted before the output connector.
