Model 5204
Dual Line Input to Dante Interface
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.
USB Dedicated Charging Port
A USB type A receptacle is located on the
back panel of the Model 5204. It allows
connection to a wide variety of devices that
obtain power for operation and/or charging
via USB. No data is transferred to or from
the Model 5204 with this connector, only
power is provided. The dedicated charg-
ing port (DCP) is capable of automatically
enumerating (“handshaking”) with a number
of the popular device protocols. This allows
operation with most mobile phones, tablet
computers, and personal audio devices.
Using the appropriate cable, simply connect
the dedicated charging port to the selected
device. Up to 5 watts of energy can be
delivered on a continuous basis. It’s pos-
sible that the device being powered and/or
charged is also serving as the source of
analog audio for line input A. In this case
two interface cables will be used to link the
device with the Model 5204.
Dante
Configuration
Several Model 5204’s Dante-related param-
eters can be configured. These configura-
tion settings will be stored in nonvolatile
memory within the Model 5204’s circuitry.
Configuration will typically be done with the
Dante Controller software application which
is available for download free of charge at
www.audinate.com. Versions of Dante Con-
troller are available to support Windows®
and OS X® operating systems. The Model
5204 uses the Ultimo 2-input/2-output inte-
grated circuit to implement the Dante archi-
tecture. However, only the two transmitter
(output) channels are utilized. This dictates
which parameters can be configured and
what choices are available.
The two transmitter channels associated
with the Model 5204’s Dante interface
must be assigned to the desired receiver
channels. Within Dante Controller a “sub-
scription” is the term used for routing a
transmitter flow (a group of output chan
-
nels) to a receiver flow (a group of input
channels). Note that as of the writing of
this guide the number of transmitter flows
associated with an Ultimo integrated circuit
is limited to two.
The Model 5204 will support audio sample
rates of 44.1, 48, 88.2, and 96 kHz with a
limited selection of pull-up/pull-down values.
The Model 5204 can serve as the clock
master for a Dante network but in most
cases it will “sync” to another device.
