Model 5204
Dual Line Input to Dante Interface
Introduction
The Model 5204 Interface is a general-
purpose audio device that supports ap-
plications 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 interfacing
of signals from a variety of sources such
as personal audio and multimedia players,
smartphones, and personal computers.
These signals typically have an average
(nominal) 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. Follow-
ing 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; channel 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 confirmation 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
government AV installations, and Dante
system testing.
For user convenience a dedicated charg-
ing port (DCP) is provided on a standard
USB type A connector. This allows power-
ing 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 desk-
top situations or deployed as a permanent
solution in fixed applications. Standard con-
nectors ensure fast, reliable deployment.
The unit requires only an Ethernet connec-
tion to supply both the data interface as
well as Power-over-Ethernet (PoE) power.
The Model 5204’s audio, data, and dedi-
cated charging port use power provided by
the PoE connection.
