Model 5204
Dual Line Input to Dante Interface
Connections
In this section signal interconnections will be
made using the connectors located on the
front and back panel of the Model 5204. An
Ethernet data connection with Power-over-
Ethernet (PoE) capability will be made using
either a standard RJ45 patch cable or an
etherCON protected RJ45 plug. Line-level
signal sources will be connected using the
3.5 mm jack associated with line input A and
the 3-pin XLR connectors associated with
line input B. The USB dedicated charging
port can be connected to power or charge
an external device.
System Components
Included in the shipping carton is a Model
5204 Interface and a printed copy of the
user guide.
Ethernet Connection
A 100BASE-TX Ethernet connection that
supports Power-over-Ethernet (PoE) is
required for Model 5204 operation. This
one connection will provide both the Ether-
net data interface and power for the Model
5204’s circuitry. A 10BASE-T connection is
not sufficient and a 1000BASE-T (“GigE”)
connection is not supported unless it can
automatically “fall back” to 100BASE-TX
operation. For PoE switch (PSE) power
management the Model 5204 will enumerate
itself as a PoE class 3 device.
The Ethernet connection is made by way of
a Neutrik etherCON protected RJ45 con-
nector that is located on the back panel of
the Model 5204. This allows connection by
way of a cable-mounted etherCON plug or
a standard RJ45 plug. The Model 5204’s
Ethernet interface supports auto MDI/MDI-X
so that most cabling implementations will be
correctly supported.
Line Input A
Line input A is intended for connection
with a 2-channel (stereo) unbalanced line-
level analog audio signal source. This will
typically be associated with consumer and
semi-professional devices such as personal
audio players, AV equipment, and tablet
and personal computers. These signals
will typically have a nominal level in the
range of –15 to –10 dBu. Devices are con-
nected to line input A by way of a 3.5 mm
3-conductor jack located on the Model
5204’s front panel. As is standard for 2-
channel (stereo) audio signals present on
this type of connector channel 1 (left) is
connected to the jack’s tip lead, channel 2
(right) to the jack’s ring lead, and the com-
mon connection to the jack’s sleeve.
Line Input B
Line input B is intended for connection with
two balanced line-level analog audio signal
sources associated with professional audio
and video equipment. These will include
devices such as audio consoles, video
storage and playback systems, wireless
microphone receivers, and audio testing
equipment. The audio quality is such that
using line input B for on-air broadcast or
streaming applications would be appropri-
ate. The two channels associated with line
input B are analog, electronically balanced,
and capacitor coupled.
The Model 5204 provides two 3-pin female
XLR connectors for interfacing signals with
line input B. Pin 2 on a mating connector
(3-pin male XLR) should be connected as
signal + (high), pin 3 as signal – (low), and
pin 1 as common/shield. With an unbal-
anced source connect signal + (high) to the
pin 2 and signal – (low/shield) to both pins
1 and 3.
