Studio Technologies, Inc. Model 5422A Dante Intercom Audio Engine, Issue 1, Page 4
from Studio Technologies use Ultimo.) While an excellent cost-
effective means of implementing Dante, using Ultimo has
several limitations. The first is its ability to support only two
transmitter and two receiver flows. Routing Dante signals
through Model 5422A pass-thru channels can facilitate integra
-
tion with applications that require additional flows.
Pass-thru can also be used as a simple means of adjusting the
level of one or more Dante signals. Using the Model 5422A’s
web menu pages, the level of each input and output channel can
be independently adjusted over a ±20 dB range. And with the
unit’s ability to support AES67 and the Dante Domain Manager
(DDM) application, many specialized interfacing tasks can be
accomplished.
Channel Level Adjustment and
Naming
The nominal level of each Dante input (receiver) channel and
Dante output (transmitter) channel can be individually adjusted.
This would apply to the 32 channels associated with the Model
5422A-01 and the 64 channels with the Model 5422A-02. The
adjustment range is ±20 dB in 1-dB steps. This capability
can be useful when using a Model 5422A to interface various
pieces of equipment that may have different internal operat
-
ing levels.
The Model 5422A includes extensive capabilities to allow the
naming of Dante audio channels. This can help ensure that
the specific configuration selected for a Model 5422A can be
understood by other technical personnel. In this way changes
to channel names won’t require the use of the Dante Control
-
ler application although the naming convention are, of course,
fully compatible.
Flexible Networking Capability
Using the Dante Controller application program, the Model
5422A’s three Gigabit Ethernet ports can be selected to operate
in one of four modes: Switched, Redundant, Switched+Mgmt,
and Redundant+Mgmt. This should allow virtually any desired
networking implementation to be easily achieved.
In the Switched mode a single Ethernet connection to either
of the Model 5422A’s two Dante Ethernet ports will provide
connectivity to the associated Dante network. The remaining
Dante Ethernet port will provide Dante network “loop-through”
capability and can be used to interface with another piece of
Ethernet-connected equipment. The management Ethernet
port will be used to access the Model 5422A’s monitoring and
configuration webpages.
In the Redundant mode two independent Ethernet connections
are made to the Model 5422A’s two Dante Ethernet ports,
enabling Dante’s redundant networking capability. Again, the
management Ethernet port will be used to access the Model
5422A’s monitoring and configuration webpages. Using either
of these network modes allows separate network connec
-
tions to be maintained for Dante audio and management
purposes.
In the Switched+Mgmt mode a single Ethernet connection is
used for both Dante audio functionality as well as providing
access to the Model 5422A’s management webpages. The
remaining Dante Ethernet port will provide network “loop-
through” capability and can be used to interface with another
piece of Ethernet-connected equipment.
In the Redundant+Mgmt mode two Ethernet connections can
be made to the Model 5422A’s two Dante Ethernet ports.
This will allow independent audio networking capability for
redundant Dante applications. Access to the Model 5422A’s
management webpages will be made by way of the Ethernet
connection made to the primary Dante Ethernet port.
Operating Power
The Model 5422A allows an AC mains source of 100-240 V,
50/60 Hz to be directly connected. It can also be powered using
a 10-18 volts DC source that is connected via a broadcast-stan
-
dard 4-pin XLR connector. If both AC and DC power sources
are connected to a Model 5422A, the unit will be powered by
the AC mains supply. Only if the AC mains source fails will a
load be placed on the DC source. This allows a source of DC,
typically a battery pack, to serve in a backup capacity. With
this arrangement normal operation can continue even if AC
mains power is lost.
Updating & Future Capabilities
The Model 5422A was designed so that its capabilities can
be enhanced in the future. A USB connector, located on the
unit’s back panel, allows the application and FPGA firmware
(embedded software) to be updated using a USB flash drive.
The Model 5422A uses Audinate’s Brooklyn II interface module
to implement Dante. The firmware in this module can easily be
updated using the Dante Updater application that is included
with the Dante Controller application. All software files and
configuration parameters are stored in non-volatile memory.
