Introduction
The Model 5204 Interface is a general-purpose audio device
that supports applications utilizing the Dante™ Audio-over-
Ethernet media networking technology. Two 2-channel
(“stereo”) analog line-level audio signals can be connected
to the Model 5204 and then converted to two channels on an
associated Dante connection.
Analog audio signals connect to line input A by way of a 3-
conductor (“stereo”) 3.5 mm jack. This allows the direct inter
-
facing of signals from a variety of sources such as personal
audio and multimedia players, smartphones, and personal
computers. These signals typically have an average (nomi-
nal) signal level in the range of –20 to –10 dBu. Line input B
supports connection of balanced analog audio signals using
two XLR connectors. Average signal levels for these types of
signals are typically in the range of 0 to +4 dBu. Each input
has an associated dual-channel rotary level control to optimize
its audio performance. Following the level “pots” the signals
from inputs A and B are summed (combined or mixed together)
to create one 2-channel signal. (The channel 1 signals of line
inputs A and B are summed to create output channel 1; chan-
nel 2 signals of line inputs A and B are summed to create
output channel 2.) The two channels are then output by way of
the Dante interface. Multi-step LED meters provide confirma-
tion of the level of the two output audio channels.
The audio quality of the Model 5204 is excellent, with low
distortion and noise and high headroom. Careful circuit design
and excellent components ensure long, reliable operation.
A wide range of applications can be supported, including TV,
radio, and streaming broadcast events, corporate and govern
-
ment AV installations, and Dante system testing.
For user convenience a dedicated charging port (DCP) is
provided on a standard USB type A connector. This allows
powering and charging of associated devices, such as personal
audio players and tablets. The compact, lightweight design
allows the Model 5204 to be used in portable or desktop situa-
tions or deployed as a permanent solution in fixed applications.
Standard connectors ensure fast, reliable deployment. The
unit requires only an Ethernet connection to supply both the
data interface as well as Power-over-Ethernet (PoE) power.
The Model 5204’s audio, data, and dedicated charging port
use power provided by the PoE connection.
Applications
The Model 5204 is perfect for use in conjunction with a variety
of fixed and portable audio equipment that offer analog out
-
put signals. An obvious application is with legacy equipment
that only offers analog outputs. A few simple connections
are all that’s required to covert those signals into the world
of Audio-over-Ethernet. When deploying, maintaining, or
modifying Dante networks the unit can be a useful test tool,
