Step 7: Routing Audio
Before you start routing audio to your Dante network, there are a few terms with
which you should become familiar:
• Device: A device means a Dante-enabled device (e.g., your StudioLive AI-series
loudspeaker with the SL-Dante-SPK option installed).
• Transmit (Tx) channel: As its name suggests, a Transmit channel transmits audio
from the audio hardware to the network.
• The SL-Dante-SPK provides two Transmit channels for your loudspeaker
when it is in Analog Input mode only:
- Full-range loudspeakers: Both channels will send the same summed
signal of the mic and line inputs.
- 18sAI subwoofers: Transmit Channel 1 will send the signal from Analog
Input 1. Transmit Channel 2 will send the signal from Analog Input 2.
• While Transmit channels for your loudspeakers are always available,
they will only contain an audio signal when the analog inputs on your
loudspeaker are active (Analog Input mode only).
• Receive (Rx) channel: A Receive channel receives audio from the network and
sends it to the audio hardware.
• The SL-Dante-SPK provides two Receive channels for your loudspeaker:
- Full-range loudspeakers: To prevent phasing issues, only Channel 1 is
sent to the DSP. Channel 2 is ignored.
- 18sAI subwoofers: Both Receive channels are sent to the DSP, where
they are summed. If you are having phasing issues, verify that you haven't
routed the same audio source to both Receive channels.
• 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.
• Unicast routing: Unicast flows are point-to-point from a single transmitter to a
single receiver. Unicast flows typically have room for four channels of audio.
• Multicast routing: Multicast flows are one-to-many from a single transmitter to
any number of receivers. Use Dante Controller to choose which 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.
• Subscription: A subscription configures a Receive channel to receive audio from a
transmit channel on another Dante device.
• 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 okay, or whether an error has occurred.
Now that you're acquainted with a few Dante networking terms, let's route some
audio. Note: The complete Dante Controller User Guide is available from
www.audinate.com/resources/technical-documentation.
Power User Tip: Dante supports devices using different samples rates on the same
network; however, you can only route audio to and from devices with the same sample
rate. StudioLive AI-series loudspeakers with SL-Dante-SPK option cards only operate
at 48 kHz on a Dante network. Any device you'd like to route audio to or from your
loudspeakers must also be set to 48 kHz.
Connect all devices on your Dante network to your switch. If you are configuring a
very large Dante network, you may want to consider adding a few components at
a time, making the necessary routing, and then moving on to the next section. For
example, you may wish to hook up your FOH system, then your monitor system, etc.
