n Transmit (Tx) channel: A transmit channel transmits audio from the audio hardware onto the

network.

n Receive (Rx) channel: A receive channel receives audio from the network and sends it to the audio

hardware.

n Flow: Dante audio routing creates flows. Each flow carries several channels of audio from a

transmitter to one or more receivers. Unicast routing creates flows to single receivers. Multicast

routing creates flows that can be received by multiple receivers. Multicast flows are assigned IDs

enabling them to be identified in Dante Controller.

n Unicast routing: Unicast flows are point-to-point from a single transmitter to a single receiver.

Unicast flows typically have room for 4 channels of audio.

n Multicast routing: Multicast flows are one-to-many from a single transmitter to any number of

receivers. Use Dante Controller to choose what channels are to be multicast. Unlike unicast routing,

multicast flows consume network bandwidth even if there are no receivers, but do not require

additional bandwidth to add more receivers.

n Subscription: A subscription configures a receive channel to receive audio from a transmit channel

on another Dante device.

n Subscription status: For a receive channel, subscription status indicates whether it is subscribed,

whether it is receiving unicast or multicast audio, whether the subscription is OK, or whether an error

has occurred.

Subscription

Dante routing is performed by associating a receiving (Rx) channel with a transmitting (Tx) channel. This is

called subscription.

Example: Route Tx channels 1 and 2 (labeled “Audio L” and “Audio R”) on the device labeled

“Source” to Rx channels 3 and 4 on the device labeled “Dest”.

Rx channels 3 and 4 on “Dest” are subscribed as follows:

n 3. Audio L@Source

n 4. Audio R@Source

Dante will perform the necessary audio routing to deliver the audio from the Tx channels to the Rx

channels.

Redundancy

Many Dante devices support redundant audio routing. These devices have two network interfaces, labeled

primary and secondary. Primary interfaces should be connected to one physical network. If redundancy is

being used, secondary interfaces should be connected to a second separate network. Secondary

interfaces cannot communicate with primary interfaces.
