Introduction
The Model 5205 Mic/Line to Dante Interface is a general-purpose audio device
that supports applications utilizing the Dante® Audio-over-Ethernet media
networking technology.
Two analog microphone or line-level audio signals can be connected to the
Model 5205. They are amplified as required and then converted to digital audio
channels on an associated Dante connection. With the inherent interoperability
of Dante, the Model 5205 can be used with other Studio Technologies Dante-
enabled products or a multitude of devices from many other manufacturers.
Microphone or line-level balanced analog audio signals are connected using two
3-pin XLR connectors. The gain of the associated preamplifier circuitry can be
selected for 0, 20, 30, 40, 50, or 60 dB. P48 phantom power is provided to
support condenser microphones. LEDs display the status of the gain and phantom
power functions. Multi-step LED meters provide confirmation of the level of
the two Dante transmitter (output) audio channels. The gain of the
preamplifiers and on/off status of the P48 phantom power sources can be
selected locally using the pushbutton switches. They can also be monitored and
selected remotely using the controller application.
The audio quality of the Model 5205’s two audio channels is excellent, with
low distortion, low noise, and high headroom. Careful circuit design and
rugged components ensure long, reliable operation. A wide range of
applications can be supported, including TV, radio, and streaming broadcast
events, corporate and government AV installations, and post-production
facilities.
The Model 5205 requires an Ethernet connection to supply both the data
interface as well as Power-over-Ethernet (PoE) power.
This requires an Ethernet connection from a PoE-enabled Ethernet switch.
Alternately, the Model 5205 can be powered by an external midspan PoE power
injector.
Applications
The Model 5205 is perfect for use in conjunction with a variety of fixed and
portable audio applications where one or two analog audio signals need to join
a Dante “network.”
The unit’s high-performance audio circuitry allows virtually any source to be
handled correctly. Essentially all
condenser, dynamic, or ribbon microphones are compatible, as are most balanced
and unbalanced analog line-level sources. The simple user controls, along with
an extensive set of status indicators, help to ensure optimum performance is
maintained. With the unit’s compact size and PoE powering, it’s simple to
deploy multiple units to integrate a distributed set of sources into a Dante
application. For permanent applications there’s no reason why a Model 5205
can’t reside within an equipment rack or be mounted, using optional brackets,
underneath a table or on-air studio set. In a conference room, settingthe unit
can be permanently connected to a PoE-enabled Ethernet port, ready to accept a
signal source from various user-provided devices.
Mic/Line Inputs
Two microphone or line-level analog audio signals can be connected to the
Model 5205’s 3-pin female XLR connectors. The preamplifier gain of each
channel can be independently adjusted from among six settings: 0 (line), 20,
30, 40, 50, or 60 dB. To support condenser microphones P48 phantom power can
be independently selected as required for each channel. LEDs are provided to
display the configuration of the gain and P48 phantom power functions. Six
pushbutton switches, located on the Model 5205’s front panel, allow local
selection of the preamplifier gain and P48 phantom power on/off status. The
controller application allows personal computer users to both view and change
the gain of the preamplifiers and the on/off status of the P48 phantom power
sources.
Audio Quality
The Model 5205’s audio performance is very good. The low-noise, wide
dynamicrange preamplifier circuitry ensures that input audio quality is
preserved. The outputs of the preamplifiers are routed to high-performance
analog-to-digital conversion (ADC) sections that support sampling rate of
44.1, 48, 88.2, and 96 kHz with a bit depth of 24. A precision voltage-
reference integrated circuit supports the ADC circuitry in performing accurate
signal conversion. The audio signals, now in the digital domain, are connected
to the Dante interface section where they are packetized and prepared for
transport over Ethernet. The P48 phantom power source is extremely low noise,
providing microphone power while causing little signal degradation. This is
important for demanding applications.
The mic/line inputs were carefully designed for use in permanent, as well as
portable and field, applications. Extensive filtering minimizes the chance
that radio frequency (RF) energy will interfere with the audio input signals.
Other components were included to specifically address ESD (“static”)
situations, helping to ensure long-term reliable operation.
Metering
Two 8-step LED meters to provide a real-time level indication of the two Dante
transmitter (output) channels. Scaled in dBFS (decibels referenced to full
scale digital) the meters offer a direct view of the audio signal levels as
they are transported via Dante in the digital domain. This is important as
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 5205 connects to an Ethernet 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 5205’s operating power is pro- vided by way of the
Ethernet interface using the 802.3af Power-over-Ethernet (PoE) standard. This
allows fast and efficient interconnection with the associated data network. To
support PoE power management, the Model 5205’s PoE interface reports to the
power sourcing equipment (PSE) that it’s a class 2 (low power) device. An LED
is provided to indicate when power is being supplied to the Model 5205.
Dante Audio-over-Ethernet
Audio data is sent from the Model 5205 using the Dante Audio-over-Ethernet
media networking technology. As a Dante-compliant device, the Model 5205’s two
transmitter (output) audio channels can be assigned to other devices using the
Dante Controller software application. The bit depth is 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.
Future Capabilities and Firmware Updating
The Model 5205 was designed so that its capabilities and performance can be
enhanced in the future. A USB connector,located on the unit’s back panel,
allows the application firmware (embedded software) to be updated using a USB
flash drive. To implement the Dante interface the Model 5205 uses Audinate’s
UltimoX2™ integrated circuit. The firmware in this integrated circuit can be
updated via the Ethernet connection, helping to ensure that its capabilities
remain up to date.
Getting Started
What’s Included
Included in the shipping carton are a Model 5205 Interface and a printed copy
of this guide. As a device that is Powerover-Ethernet (PoE) powered, no
external power source is provided. Should a PoE midspan power injector be
required it must be purchased separately.
Mounting Options
There is no provision for directly mounting one or more Model 5205 units in an
equipment rack. However, the overall height of the unit was carefully selected
so that it could be placed without interference on a single space (1U) rack
shelf. The Model 5205’s enclosure width allows up to four units to be placed
side-by-side on a 1U shelf that’s mounted in a standard 19-inch equipment
rack. Hook-and-loop (“Velcro”) tape can be used to secure the Model 5205 units
to the shelf. A set of mounting brackets is available to allow a Model 5205 to
be attached to the underside of a desk, table, broadcast set, or another flat
surface. The order code for this item is MBK-02.
Connections
In this section signal interconnections will be made using the connectors
located on the back panel of the Model 5205.
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. Microphone or line-level signal sources will be connected using two
cable mounted 3-pin male XLR connectors.
Ethernet Connection
A 100BASE-TX Ethernet connection that supports Power-over-Ethernet (PoE) is
required for Model 5205 operation. This one connection will provide both the
Ethernet data interface and power for the Model 5205’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-supporting Ethernet switch power management the Model 5205 will enumerate
itself as a PoE class 2 device. The Ethernet connection is made by way of a
Neutrik etherCON protected RJ45 connector that is located on the back panel of
the Model 5205. This allows connection by way of a cable-mounted etherCON plug
or a standard RJ45 plug. The Model 5205’s Ethernet interface supports auto
MDI/MDI-X so that most cabling implementations will be correctly supported
without requiring a “cross-over” or “reversing” cable.
Ethernet Port without PoE
As previously discussed in this guide, the Model 5205 was designed such that
the ethernet connection will provide both data and Power-over-Ethernet (PoE)
power. There may be situations where the associated Ethernet switch does not
provide PoE power. In these cases an external PoE midspan power injector can
be used. As long as the midspan power injector is 802.3af-compatible it should
function correctly. Midspan units are available from a variety of sources,
including Studio Technologies.
Mic/Line Inputs
The two mic/line inputs are intended for connection with a balanced microphone
or line-level analog audio signal sources. Typically these sources will be
associated with professional audio equipment such as the dynamic, condenser,
or ribbon microphones, audio consoles, video storage and playback systems,
wireless microphone receivers, and audio testing equipment. The Model 5205
provides two 3-pin female XLR connectors for interfacing analog audio signals
with the mic/line inputs. For balanced signals pin 2 should be connected to
signal + (high) and pin 3 should be signal – (low). Pin 1 should be connected
to the shield of the interconnecting cable. Unbalanced signals can also be
connected. In most cases signal + (high) should be connected to pin 2 and
common/shield should be connected to both pins 1 and 3 of the 3-pin male XLR
mating connector. If this connection arrangement results in hum or noise it
may be effective to try connecting signal + (high) to pin 2 and signal
common/shield only to pin 3.
Dante Configuration
Several Model 5205’s Dante-related parameters can be configured. These configuration settings will be stored in non-volatile memory within the Model 5205’s circuitry. The configuration will typically be done with the Dante Controller software application which is available for download free of charge at audinate.com. Versions of Dante Controller are available that include support for the Windows® and macOS® operating systems. The Model 5205 uses the UltimoX2 2-input/2-output integrated circuit to implement the Dante architecture. However, only the two transmitters (output) channels are utilized. This dictates which parameters can be configured and what choices are available. The two transmitters (output) channels associated with Model 5205’s Dante interface must be assigned to the desired receiver (input) channels. Within Dante Controller a “subscription” is the term used for routing a transmitter flow (a group of output channels) to a receiver flow (a group of input channels). The number of transmitter flows associated with an UltimoX2 integrated circuit is limited to two. These can either be unicast, multicast, or a combination of the two. The Model 5205 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 5205 can serve as the Leader clock for a Dante network but in most cases it will be configured to “sync” to another device. The Model 5205 has a default Dante device name of ST-M5205 and a unique suffix. The suffix identifies the specific Model 5205 that is being configured. The suffix’s actual alpha and numeric characters relate to the MAC address of the UltimoX2 integrated circuit. The two Dante transmitter (output) channels have default names of Ch1 and Ch2. Using Dante Controller the default device name and channel names can be revised as appropriate for the specific application.
Operation
At this point an Ethernet connection with Power-over-Ethernet (PoE) capability
should have been made. The Model 5205’s Dante configuration settings should
have been selected using the Dante Controller software application. At a
minimum, the two Dante transmitter (output) channels should have been routed
to receiver (input) channels on an associated device. Analog signal sources
should have been connected to the two mic/line inputs. Normal Model 5205
operation can now begin.
Initial Operation
The Model 5205 will begin to function as soon as a Power-over-Ethernet (PoE)
power source is connected. However, full operation may take 20 seconds or
longer to begin. Upon initial power up the four status LEDs located on the
back panel will begin to light. The USB LED on the back panel and the P48,
gain, and meter LEDs on the front panel will light in a test sequence. After
the LEDs complete their test sequence one LED associated with the level meter
for channel 1 and one LED associated with the level meter for channel 2 will
briefly light to indicate the version number of the unit’s application
firmware (embedded software). (Understanding how to“read” the application
firmware number will be discussed in detail later in this guide.) Once the
entire sequence has completed and the Dante connection has been established
full operation will begin.
Ethernet, PoE, and Dante Status LEDs
Four status LEDs are located below the etherCON connector on the Model 5205’s
back panel. The PoE LED will light green to indicate that Power-over-Ethernet
(PoE) power associated with the connected Ethernet signal is providing
operating power for the Model 5205. The LINK/ACT LED will light green whenever
an active connection to a 100 Mb/s Ethernet network has been established. It
will flash in response to Ethernet data packet activity. The SYS and SYNC LEDs
display the operating status of the Dante interface and associated network.
The SYS LED will light red upon Model 5205 power up to indicate that the Dante
interface is not ready. After a short interval, it will light green to
indicate that it is ready to pass data with another Dante device. The SYNC LED
will light red when the Model 5205 is not synchronized with a Dante network.
It will light solid green when the Model 5205 is synchronized with a Dante
network and an external clock source (timing reference) is received. It will
slowly flash green when the Model 5205 is part of a Dante network and is
serving as a Leader clock.
How to Identify a Specific Model 5205
The Dante Controller software application offers an identify a command that
can be used to help locate a specific Model 5205. When identity is selected
for a specific unit its meter LEDs will light in a unique pattern. In
addition, the SYS and SYNC LEDs, located directly below the etherCON connector
on the back panel, will slowly flash green. After a few seconds the LED
identification patterns will cease and normal Model 5205 level meter and Dante
status LED operation will again take place.
Level Meters
Two 8-step LED meters display the level of the two Dante transmitter (output)
channels. The meter steps are calibrated in dBFS which indicates the number of
dB below the maximum possible digital signal level. The maximum level, 0 dBFS,
is the digital audio reference level equal to “full scale.” Full scale refers
to the maximum level possible for a sine wave before “digital clipping.” In
typical applications, a signal with a nominal (normal) level of –20 dBFS would
be desirable. The five-meter steps have a threshold of –20 dBFS and less light
with the color green. The steps that light at –15 and –10 dBFS are yellow in
color and indicate “hot” or above average signal levels. The top step lights
red in color when a signal level is –5 dBFS or greater, indicating that a
potentially “clipped” (distorted due to excessive level) signal is present.
Mic/Line Inputs
Two 3-pin female XLR connectors are provided to interface analog audio signals
with the Model 5205’s mic/line inputs. Balanced and unbalanced signals with a
wide range of nominal levels can be successfully connected. As expected, a
signal connected to the channel 1 mic/line input connector is associated with
Dante transmitter (output) channel 1. A signal connected to the channel 2
mic/line input connector is associated with Dante transmitter (output) channel
2.
Preamplifier Gain Selection
Two pushbutton switches are associated with each mic/line input and are used
to locally adjust the gain of the preamplifier circuitry. In the 0 dB (line)
position the Model 5205 will provide no (unity) gain. In this specific case a
connected analog signal that has a level of precisely 0 dBu will result in a
Dante digital audio level of –20 dBFS. (That corresponds to 20 dB less than
the maximum possible level.) Five other settings allow a gain of 20 to 60 dB,
in 10-dB steps, to be selected. Select the preamplifier gain such that normal
input signals will cause the five green LEDs to light. Peak signals can cause
the yellow LEDs to light on occasion. But the yellow LEDs should never be
continuously lit. The red LED should never light, except possibly in the case
of an extreme peak. The red LED lighting on a regular basis indicates that the
signal level is at risk of reaching digital 0 (0 dBFS) which is destructive to
audio quality. When changing from the 0 dB to the 20 dB gain setting, or vice-
versa, a slight mechanical click or “tick” sound may be heard coming from
within the Model 5205’s enclosure. This is caused by the changing state of an
electro-mechanical relay that places a 20 dB attenuator network in to or out
of the signal path. Note that due to a technical consideration the exact gain
values are slightly different from the nominal values that are indicated on
the front panel graphics and in most of the text provided in this guide. As
such, there can be up to a 1-dB difference, high or low, at some gain
settings. This will typically have no impact on the performance or use of the
Model 5205. But laboratory or other precision testing of the Model 5205 will
show these apparent anomalies. Refer to the Specifications section of this
guide for the exact values.
P48 Phantom Power
To support microphones that require external power, the Model 5205 can provide
a source of P48 phantom power. Press the P48 button associated with the
desired channel to locally change the on/off status of the P48 phantom power
source. The P48 LED will light when P48 phantom power is being provided to the
associated mic/line input connector. For maximum flexibility P48 phantom power
is available in all six of the preamplifier gain settings, including 0 dB
(line). While P48 phantom power would not typically be needed in the 0 dB
(line) setting it’s still available for special applications. This can include
use with high-sensitivity microphones being used in environments with high-SPL
audio levels.
Remote Configuration of Gain and P48 Phantom Power
Using the controller application allows personal computer users to view and
adjust the Model 5205’s preamplifier gain and P48 phantom power on/off status.
The application is available for download on the Studio Technologies website
(studio-tech.com). Versions are available that
support the Windows and macOS operating systems. Changes made using the
application will be displayed in real-time on the Model 5205’s LED indicators.
Changes made to the preamplifier gain and P48 on/off status using the Model
5205’s local pushbutton switches will be displayed in the controller.
Button Lock-Out
There may be situations where it’s desirable for the preamplifier gain and P48
phantom power on/off configurations to be maintained without the risk that an
unauthorized user will press one of the buttons and cause an unwanted change
to be made. A button lock-out function is included to minimize the chance that
this will occur. Using the function is very simple: simultaneously press and
hold both P48 buttons for approximately 2 seconds until the two P48 LEDs
flash. This will indicate that a change has been made to the button lock-out
status. When the button lock-out function is enabled the six pushbuttons will
no longer allow any local preamplifier gain or P48 configuration changes to be
made. During operation, if the buttons are “locked” pressing a P48, gain up,
or gain down button will cause both P48 LEDs to flash three times but no
change will occur. Only by changing the status of the lock-out function, by
pressing and holding both P48 buttons, will local changes to the gain or P48
on/off status be allowed. Remote monitoring and control using the controller
application will continue to function normally, even if the buttons are in
their locked-out state.
Configuration Storage
The selected configuration of the preamplifier gain and P48 on/off status, as
well as the button lock-out status, will be stored in nonvolatile memory
within Model 5205. This allows the settings to be “remembered” during periods
when the Model 5205 is not being provided with power.
Upon the unit being powered up the stored settings will again be used.
USB Interface
A USB type A connector and associated status LED is located on the back panel
of the Model 5205. This data interface is used only for updating the unit’s
application firmware. No audio data of any kind will pass through it. For
details please refer to the Technical Notes section of this guide.
Technical Notes
IP Address Assignment
By default, the Model 5205’s Ethernet interface will attempt to obtain an IP
address and associated settings using DHCP (Dynamic Host Configuration
Protocol). If a DHCP server is not detected an IP address will be assigned
using the link-local protocol. This protocol is known in the Microsoft® world
as Automatic Private IP Addressing (APIPA). It is also sometimes referred to
as auto-IP (PIPPA). Link-local will assign an IP address in the IPv4 range of
169.254.0.1 to 169.254.255.254. In this way multiple Dante-enabled devices can
be connected together and automatically function, whether or not a DHCP server
is active on the LAN. Even two Dante-enabled devices that are directly
interconnected using an RJ45 patch cord will correctly acquire IP addresses
and be able to communicate and transport audio. Using the Dante Controller
software application Model 5205’s IP address and related network parameters
can be set for a fixed (“static”) configuration. While this is more involved
than letting DHCP or link-local “do their thing,” if fixed addressing is
necessary then that capability is available. But in this case it’s highly
recommended that each unit be physically marked, e.g., directly using a
permanent marker or “console tape,” with its specific IP address. If knowledge
of a Model 5205’s IP address has been misplaced there is no reset button or
other method to restore the unit to a default IP setting. In the unfortunate
event that a device’s IP address is “lost,” the Address Resolution Protocol
(ARP) networking command can be used to “probe” devices on a network for this
information. For example, in Windows OS the arp –a command can be used to
display a list of LAN information that includes MAC addresses and
corresponding IP addresses. The simplest means of identifying an unknown IP
address is to create a “mini” LAN with a personal computer connected directly
to the Model 5205. Then by using the appropriate ARP command the required
“clues” can be obtained.
For best Dante audio-over-Ethernet performance a network that supports VoIP
QoS capability is recommended. This can typically be implemented on virtually
all contemporary managed Ethernet switches. There are even specialized
switches that are optimized for entertainment-associated applications. Refer
to the Audinate website (audinate.com) for details on
optimizing networks for Dante applications.
Application Firmware Version Display
As part of the Model 5205’s power-up sequence, the unit’s application firmware
version number is displayed. This is useful when working with factory
personnel on application support and troubleshooting. The eight LEDs
associated with the channel 1 level meters are used to display the major
version number with a range of 1 through 8. The eight LEDs associated with the
channel 2 level meters are used to display the minor version number which
ranges from 1 through 8. Refer to Figure 2 for a detailed view of the LEDs and
the corresponding application firmware version numbering scheme.
Application Firmware Update Procedure
It’s possible that updated versions of the application firmware (embedded
software) that is utilized by the Model 5205’s microcontroller (MCU)
integrated circuit will be released to add features or correct issues. Refer
to the Studio Technologies website for the latest application firmware file.
The unit has the ability to load a revised file into the MCU’s nonvolatile
memory by way of a USB interface. The Model 5205 implements a USB host
function that directly supports the connection of a USB flash drive. The Model
5205’s MCU updates its firmware using a file named m5205.bin. The update
process begins by preparing a USB flash drive. The flash drive doesn’t have to
be empty (blank) but must be in the personal-computer-standard FAT32 format.
Save the new firmware file in the root folder with the name of m5205.bin.
Studio Technologies will supply the application firmware file inside a .zip
archive file. While the firmware file inside of the zip file will adhere to
the naming convention required by the Model 5205, the name of the zip file
itself will include the file’s version number.
Figure 2. Detail of front panel showing the level meter LEDs that display the application firmware version. In this example, the application firmware version shown is 2.3.
For example, a file named m5205v2r3MCU.zip would indicate that version 2.3 of the application firmware (m5205.bin) is contained within this zip file. Once the USB flash drive is inserted into the USB interface, the unit is powered off, and again powered on, the file will automatically load. The precise steps required will be highlighted in the next paragraphs of this guide. After the firmware has been updated the two LED level meters should be used to confirm that the desired application firmware version has been successfully installed. To install the application firmware file follow these steps:
- Remove power from the Model 5205. This will entail removing the Ethernet connection that is providing PoE power.
- Ensure that nothing is present in the USB port. Then again apply power to the unit and “read” the currently loadedapplication firmware version during the power-up sequence using the two level meters. (Refer to the Application Firmware Version Display paragraph earlier in this section.) Record the version number for later reference.
- Remove power from the Model 5205.
- Insert the prepared USB flash drive into the Model 5205’s USB port, located on the back panel of the unit.
- Apply power to the Model 5205. Power is provided by Power-over-Ethernet (PoE) associated with the connected Ethernet signal.
- The Model 5205 will run a “boot loader” program that will immediately load the new application firmware file (m5205.bin). This process takes only a few seconds. During this time period, the LED located below the USB connector will flash slowly on and off the green. Once the entire loading process is over, taking approximately 10 seconds, the model 5205 will restart using the newly loaded application firmware.
- At this time the Model 5205 is functioning with the newly loaded application firmware and the USB flash drive can be removed. But to be conservative, remove power first nd then remove the USB flash drive.
- Apply power to the Model 5205 and “read” the application firmware version number by observing the two-level meters. Ensure that this is the desired version and that it’s different from that noted in step 2. Note that upon power being applied to the Model 5205 if the USB flash drive doesn’t have the correct file (m5205.bin) in the root folder no harm will occur. Upon power up the USB LED will flash on and off rapidly for a few seconds to indicate this condition and then normal operation using the unit’s existing application firmware will begin.
UltimoX2 Firmware Update
As previously discussed in this guide, Model 5205 implements Dante
connectivity using the 2-input/2-output UltimoX2 integrated circuit from
Audinate. The Dante Controller software application can be used to determine
the version of the firmware (embedded software) residing in the UltimoX2
“chip.” This firmware can be updated by way of the Model 5205’s Ethernet
connection. The latest Dante firmware file is available on the Studio
Technologies website. The Dante Firmware Update Manager application is used to
install the firmware. This program is also available for download on the
Studio Technologies website.
