Model 5202
Dante to Phones and Line Output Interface
Line Outputs
The Model 5202 provides a 2-channel
line-level, electronically-balanced analog
audio output by way of standard 3-pin male
XLR connectors located on the back panel.
A rotary level control allows the nominal
(average) level of the line outputs to be
adjusted. Using the push-in/push-out knob
it’s a simple matter to achieve the desired
nominal output levels which include –10,
0, or +4 dBu. And with a maximum out-
put level of +24 dBu there will always be
sufficient headroom for “pro” audio per-
formance. Protection components in the
output circuitry help ensure reliability in
field applications.
The line outputs can serve a number of
monitoring and interfacing uses. Audio
amplifiers or amplified speakers can be
directly connected. The level control can be
used to adjust the speaker volume or used
as a level trim function to match the speak-
er’s input sensitivity. The line outputs can
also serve as a source for interfacing with
analog inputs on audio consoles, wireless
in-ear or IFB monitor systems, as well as
audio recording devices. The level control
will help to ensure that the nominal level
of the line outputs will match the require-
ments of the connected equipment.
Metering
Two 7-step LED meters provide a real-time
level indication of the two Dante-supplied
audio channels. Scaled in dBFS (decibels
referenced to full scale digital) the meters
offer a direct view of the signal levels as
they arrive in the digital domain. Optimal
audio performance requires transporting
signals at their proper levels — without an
accurate indication this can be difficult to
achieve.
Ethernet Data and PoE
The Model 5202 connects to a data network
using a standard 100 Mb/s twisted-pair
Ethernet interface. The physical intercon-
nection is made by way of a Neutrik®
etherCON RJ45 connector. While compat-
ible with standard RJ45 plugs, etherCON
allows a ruggedized and locking intercon-
nection for harsh or high-reliability environ-
ments. An LED displays the status of the
network connection.
The Model 5202’s operating power is pro-
vided by way of the Ethernet interface using
the Power-over-Ethernet (PoE) standard.
This allows fast and efficient interconnec-
tion with the associated data network. To
support PoE power management the Model
5202’s PoE interface reports to the power
sourcing equipment (PSE) that it’s a class 1
(very low power) device. An LED is provided
to indicate when power is being supplied
to the Model 5202. Note that no provision
has been made to allow an external power
source to be connected. However, if the
associated Ethernet switch does not provide
PoE capability a commonly-available mid-
span PoE power injector can be utilized.
Dante Audio-over-Ethernet
Audio data is sent to the Model 5202
using the Dante Audio-over-Ethernet
media networking technology. As a Dante-
compliant device, two audio channels can
be assigned to the unit using the Dante
Controller software application. A single
mouse-click is all that’s required to route
an audio signal to the Model 5202. Bit
depths of up to 24 and sample rates of
44.1, 48, 88.2, and 96 kHz are supported.
Two bi-color LEDs provide an indication of
the Dante connection status. The Model
5202 uses Audinate’s Ultimo™ integrated
