MODEL 348
INTERCOM STATION
Dante Configuration
For audio to correctly pass to and from the
Model 348 requires, as a minimum, that sev-
eral Dante-related parameters be configured.
These configuration settings will be stored in
non-volatile memory within the Model 348’s
circuitry. Configuration will typically be done
with the Dante Controller software application
which is available for download free of charge
at www.audinate.com. Versions of Dante
Controller are available to support Windows
and OS X® operating systems. The Model 348
uses the Broadway integrated circuit to imple-
ment the Dante functionality. The Model 348
is compatible with the Dante Domain Manager
(DDM) software application.
Audio Routing
The Model 348’s 11 Dante transmitter (Tx)
channels must be assigned to the desired
receiver channels on associated equipment.
This will route the Model 348’s eight talkback,
two monitor, and one hot mic output channels
to the devices that will be “listening” to them.
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 of input channels).
The number of transmitter flows associated
with a Broadway integrated circuit and, as
such the Model 348, is 16 so no limitation can
exist. These flows can either be unicast, mul-
ticast, or a combination of the two. (Note that
in the AES67 mode the transmitter (output)
channels will function in multicast; unicast is
not supported.)
Using Dante Controller the desired audio
sources need to be routed to the 16 receiver
(Rx) channels associated with the Model 348’s
Dante audio inputs. The exact number utilized
will depend on the specific application. The
first eight receiver channels are automatically
assigned to the level encoders and can be
used for listening to the associated intercom
channels or as general-purpose audio channel
monitoring. The second set of eight receiver
channels are associated with the IFB (talent
cueing) functions. They will be utilized only with
channels that have their IFB function enabled.
Unit and Channel Names
The Model 348 has a default Dante device
name of ST-M348- along with a unique suf-
fix. The suffix identifies the specific Model 348
that is being configured. The suffix’s actual
alpha and/or numeric characters relate to the
MAC address of the unit’s Broadway integrated
circuit. The 16 Dante receiver (Rx) audio input
channels have default names of Ch 1 – Ch 8
and IFB Pgm 1 – IFB Pgm 8. The 11 Dante
transmitter (Tx) audio output channels have
default names of Ch 1 – Ch 8, Mon A, Mon B,
and Hot Mic. Using Dante Controller the de-
fault device name and channel names can
be revised as appropriate for the specific
application.
Device Configuration
The Model 348 only supports an audio sample
rate of 48 kHz with no pull-up/pull-down values
available. Encoding choices are PCM 24, PCM
16, and PCM 32 but in virtually all cases the
default selection of PCM 24 would be appro-
priate. Clocking and Device Latency can be
adjusted if required but the default values are
typically correct.
Network Configuration – Dante Redundancy
The Model 348 allows connection of two Ether-
net signals. Two RJ45 jacks are located on the
unit’s back panel and are labeled Primary-PoE
and Secondary. In the network configuration
Dante Redundancy section of Dante Controller
how these ports function can be selected. The
choices are Switched or Redundant.
