As previously discussed, the Model 48D’s
LCD display and pushbutton switches
allow changes to both of the unit’s Dante
network interfaces. But it’s important to
note that when using Dante Controller
to make changes to the operation of a
specific network interface one must run a
designated instance of the application. A
personal computer that’s running Dante
Controller would have to have its associat-
ed local-area-network interface connected,
by way of a port on an Ethernet switch,
to the applicable RJ45 receptacle. This is
because the Model 48D provides two fully-
isolated Dante interfaces.
Configuration using Dante
Controller
The Dante Controller software application
is available for download free of charge
at www.audinate.com. Versions are avail-
able to support Windows® and OS X®
operating systems. Using Dante Controller
the Model 48D’s two network interfaces
can be configured for their desired net-
work parameters, performance choices,
and channel subscriptions (routing). The
configuration settings will be stored in
non-volatile memory within the Model
48D’s circuitry. As such, power-down and
power-up activities will not impact the
unit’s settings. The Model 48D uses two
Ultimo 4-input/4-output integrated circuits
to implement Dante networking.
Network Parameters
The method used to determine the net-
work IP addresses can be selected with
the choices of Automatic or Manual. De-
tails about the automatic process can be
found in the Technical Notes section of
this guide. If Manual is selected a specific
IP address can be entered along with the
subnet mask value. Typically a reboot of an
interface is required for new network inter-
face values to be utilized.
Sample Rate
The sample rate of the Dante interface
can be selected with choices of 44.1 kHz,
48 kHz, 88.2 kHz, and 96 kHz. Several pull-
up/pull-down value configuration choices
are also available. The selected sample
rate for the two Dante interfaces does not
have to be the same. Circuitry within the
Model 48D will correctly interconnect dif-
ferent sample rates. If both interfaces are
selected for 44.1 or 48 kHz four audio chan-
nels can be bridged between the Model
48D’s network interfaces. If either
or both network interfaces are selected
for a sample rate of 88.2 or 96 kHz then
only two audio channels can be bridged
between the two network interfaces.
AES67 Support
The ability to support AES67 can also be
selected with choices of Disabled or En-
abled. If selected for Enabled the sample
rate is automatically configured for 48 kHz,
overriding any other value. This is because
48 kHz is the only sample rate that can
be supported when a Dante interface is
compliant with AES67.
Audio Channel Subscriptions
To integrate the Model 48D into an actual
application requires that the transmitter and
receiver audio channels associated with
Network A and Network B be routed (inter-
connected) with other Dante-compatible
devices. This is typically performed with the
Dante Controller application. Within Dante
Controller a “subscription” is the term used
for routing a transmitter flow (a group of
output channels) to a receiver flow (a group
