Introduction
The Model 48D Dante
®
Bridge provides
a simple yet high-performance means of
interconnecting, or “bridging,” Dante audio
signals associated with two independent
local-area-networks. The unit allows up to
four audio channels to pass in each direc-
tion. Internal circuitry provides timing and
bit-depth correction to ensure that audio
signal integrity is maintained.
Dante audio-over-Ethernet has found wide
acceptance as a network “backbone” due
to its ease of use, excellent audio perfor-
mance, strong interoperability, and wide
adoption by a large number of equipment
manufacturers. However, interconnecting
audio signals on independent local-area-
networks that support Dante can present
a challenge. The Model 48D makes that a
simple task to implement. Interconnecting
a Model 48D with two Ethernet connec-
tions, along with a minimal amount of
configuration, is all that’s required to make
the unit part of a sophisticated, networked
audio system.
The Model 48D can be powered by Power-
over-Ethernet (PoE) or an external source
of 12 volts DC. Standard connectors are
used for the Ethernet and DC power inter-
connections. The Model 48D’s enclosure
has a “1/2-rack” 1U form factor and weighs
less than two pounds, making it well suited
for use in portable applications. Alternately,
using one of the optional rack-mounting
kits one or two Model 48D units can be
mounted in a single space (1U) of a stan-
dard 19-inch rack enclosure. The unit is
built to professional standards and is in-
tended for demanding 24-hour operation.
The Dante Controller software application
can be used to configure all Dante network
and audio parameters. Front-panel LED
indicators, an LCD display, and five push-
button switches are provided to view and
revise selected operating parameters. The
Model 48D is compatible with the Dante
Domain Manager™ (DDM) software appli-
cation and is complaint with AES67 digital
audio signals.
