Advanced Configuration with Dante
Controller
Once you have installed a Dante-MY16-AUD2 card in your Yamaha equipment and connected it to a
network, you can configure your card using a PC or Mac on the same network with Dante Controller
installed and running on it.
Some basic functions of Dante Controller have already been described:
n
Setting up an audio route.
n
Changing the device name.
n
Changing sample rate.
n
Identifying a specific Dante-MY16-AUD2 card.
Dante Controller can also be used to configure a number of other more advanced features, including:
n
Adjusting latency settings
n
Choosing between unicast and multicast modes
n
Selecting clock sources
n
Specifying static IP addresses
These are described briefly below. A more complete description of the functions of Dante Controller can be
found in the
Unicast and Multicast Modes
Dante audio routing creates flows. Each flow carries one or more channels of audio from a transmitting
device to one or more receiving devices. There are two types of flow, unicast and multicast.
Unicast routing creates flows to a single receiving device; a unicast flow typically assigns space for 4
channels of audio. Unicast flows are set up when a receiver subscribes to an available audio channel, and
are automatically removed when the receiver unsubscribes from all channels in that flow.
Multicast routing creates flows that can be received by multiple receivers. Multicast flows are assigned
IDs enabling them to be identified in Dante Controller and to facilitate their removal. In contrast to unicast
flows, multicast flows are set up on the transmitting Dante device.
Dante routing is unicast by default. This means that a separate flow is set up for each pair of transmitter
and receiver. If several receivers are all subscribed to the same channels of a transmitter, it may
sometimes be more efficient to use multicast.
Multicast sends the same set of channels to multiple receivers. In practice, this usually means that the
audio flow is flooded throughout the network. If many receivers want the same channels, using multicast
can reduce overall network use, especially on the transmitter since only one copy of each audio channel
needs to be sent rather than many. Unlike unicast routing, multicast flows consume network bandwidth
even if there are no receivers, but do not require additional bandwidth to add more receivers.
Dante receivers will automatically prefer multicast to unicast if it is available. This means that if a new
multicast flow is created containing the channels that a receiver is currently receiving as unicast, the
receiver will switch over to receiving audio from the multicast flow and the unicast flow will be removed.
Dante Controller can be used to choose what channels are to be multicast.
