Introduction

The Model 5202 Interface is a general-purpose audio device

that supports applications utilizing the Dante™ Audio-over-

Ethernet media networking technology. Two Dante-associ

ated audio channels can be assigned to the Model 5202

which provides headphone and balanced line-level outputs.

The audio quality is such that virtually any audio application

can be supported, from simple headphone or loudspeaker

monitoring to interfacing with high-performance on-air

broadcast, stadium AV, or corporate audio systems. Multi-

step LED meters provide confirmation of the level of the

two input audio channels. The compact, lightweight design

allows the Model 5202 to be used in portable or desktop

situations or deployed as a permanent solution in fixed

applications. Standard connectors ensure fast, reliable

deployment. The unit requires only an Ethernet connection

to supply both the data interface as well as Power-over-

Ethernet (PoE) power.

Applications

The Model 5202 is perfect for use in conjunction with the

Dante Controller software application. Driving a pair of

headphones or set of amplified speakers, audio flows and

associated channels can be quickly confirmed for content as

well as signal level. For field applications the unit can serve

as both a test tool and a general-purpose source of analog

audio outputs. With level controls associated with both the

headphone and line outputs interfacing with virtually any

analog audio input is a simple matter. For permanent ap

plications there’s no reason why a Model 5202 can’t reside

within an equipment rack or be mounted, using optional

brackets, underneath a table or on-air studio set. The low-

power circuitry is intended for continuous operation.

Headphone Output

A sonically-excellent 2-channel (stereo) headphone output

is provided. It is capable of driving contemporary head

phones, headsets, and earbuds to substantial levels at

very low distortion. A rotary control is used to adjust the

headphone output level. The level knob is a push-in/push-

out type which helps prevent inadvertent adjustment. For

flexibility the headphone output is provided on two separate

3-conductor jacks: a 3.5 mm on the front panel and a ¼-inch

on the back. The audio quality of the headphone output is

such that it can also be used as a 2-channel unbalanced

line output. The output level control will make it a simple

task to optimally interface the headphone output with in

puts on personal computers, portable audio devices, and

“semi-pro” equipment.

Line Outputs

Ethernet Data and PoE

The Model 5202 provides a 2-channel line-level, electroni-

cally-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 suf

ficient headroom for “pro” audio performance. 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 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 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 indica

tion this can be difficult to achieve.

-

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 ruggedized 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 interconnection

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 as

signed to the Model 5202 using the Dante Controller soft

ware application. 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.
