Model 5202 Interface, Issue 1, Page 2
Line Outputs
The Model 5202 provides a 2-channel line-level, electron-
ically-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 output level of +24 dBu there will
always be sufficient headroom for “pro” audio perfor-
mance. 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 speak-
ers 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 speaker’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 requirements
of the connected equipment.
Metering
Two 7-step LED meters provide a real-time level indica-
tion 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 interconnection is made by way of a
Neutrik® etherCON RJ45 connector. While compatible
with standard RJ45 plugs, etherCON allows a rugge-
dized and locking interconnection for harsh or high-
reliability environments. An LED displays the status
of the network connection.
The Model 5202’s operating power is provided by way
of the Ethernet interface using the Power-over-Ethernet
(PoE) standard. This allows fast and efficient intercon
-
nection 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 capa-
bility 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 circuit for implementing
Dante. The integrated circuit’s firmware can be updated
via the Ethernet connection, helping to ensure that its
capabilities remain up to date.
