1 – Overview

The Synapse DM1 is a rackmount networked audio monitor for
confidence monitoring of networked audio and local sources via
headphones or through the integrated speakers. The DM1 has 2
modes for network audio monitoring: Standard and Extended.

Standard mode features monitoring of any of the 32 channels
assigned to the Dante™/AES67 receiver inputs.

Extended mode allows subscription based monitoring of up to 128
channels loaded to the DM1 using the unIFY control Panel
software.

In both modes, audio may be selected for monitoring by the user
via the front panel controls. The DM1 also features AES-3 digital
outputs for connectivity to full range powered speakers or
amplifiers and 2 channels of analog I/O for local source monitoring
and network connectivity.

The front panel features an accessible integrated headphone amp
and a high contrast OLED display to provide quick and detailed
feedback for audio confidence monitoring and diagnostics.

The 24V power supply comes pre-mounted to the DM1 chassis but
there is also support for a secondary external 24V DC supply for
optional power redundancy.

On the network side, there is a fully redundant Dante™ interface
utilizing both RJ45 connectors and SFP ports. The SFP ports allow
the DM1to utilize direct fiber connectivity for long range signal
extension in physically large systems such as arenas, large
corporate buildings and convention centers.

Audinate’s Dante™ Controller or other 3rd party manufacturer's
Dante™ routing software can be used to control the Dante™ audio
routing configuration of the device while the Attero Tech unIFY
Control Panel application can be used to configure the device­specific features.

1.1 – What’s in the Box

2 – Device Installation

2.1 – Mounting

The case for the DM1 is designed ready to fit in a standard 19”
rack. The rack mount tabs are built in to the front panel of the
unit (rack screws are not supplied). Use four screws to secure
the unit to the rack. Dimensioned drawings can be obtained by
logging into Attero Tech’s customer portal

.

2.2.1 – Balanced Input from Balanced Output

Figure 1 – Mounting and Dimension Information

2.2 – Audio Connections

All connections to the Synapse DM1 should be made before the
power is applied. Attach analog audio sources to the analog
audio inputs. Attach analog audio destinations to the analog
audio outputs. Digital AES-3 destinations should be connected
to the AES-3 output. The analog audio outputs are balanced, so
be sure to check what input type the destination device uses in
order to find how to connect it correctly. Refer to the following
diagrams and instructions for connecting different types of
audio devices.

2.2.4 – Balanced Output to Unbalanced Input

2.3 – External Clocking

The DM1 is equipped with a single word clock input and output
for synchronizing digital devices. A user switchable 75 Ω clock
termination impedance is also located on the back panel.

2.4 – Power Supply

Use the provided AC power cable to connect a standard AC outlet
to the power supply input connector. There is no “on” switch so
the unit will power up as soon as the power connection is made.

*Note: If using the optional backup supply, avoid connecting a
powered supply to the unit. It is recommended to attach the power
supply to the D32o first, then connect the power cord to the power
supply to supply power to it.

Once powered, the screen on the front of the unit should turn on
and show the Attero Tech logo, the status LED should be red and
the mute LED should be flashing red rapidly. Initialization can up
to 20 seconds depending on how the device is setup. Once
initialized, the status LED will turn green, the mute LED will go
out, and the screen will change to show the first of the metering
screens.

There may also be some activity on the Dante™ RJ45 Ethernet
connector LEDs. If a cable is connected and no network is
detected, both LEDs will remain off. If an active connection is
made the green LED will come on and the yellow LED will flash.

2.5 – Network Connections

*Note: All Attero Tech products are tested using UTP cabling and
it is recommended that UTP cabling be used when installing them.
STP cabling can be used for installation though care must be
taken not to introduce grounding issues into the system by doing
so.

Network connection is made using the RJ45 ports and SFP ports.
To use an SFP port, a suitable SFP module(s) will be required to
be installed. These are not included with the D32o and must be
purchased separately. In general, any 1Gbit SFP compatible
module may be used.

*Note: If there is no network connection, the front panel will show
“No Network” in the center of all the metering screens. The
network screen will also indicate that there are no active
interfaces.

Dante™ networks can be configured in two different ways:
standalone or redundant. The Synapse D32o can be used in either
configuration. By default the D32o is set to “Redundant” mode
but this can easily be changed using Dante™ Controller.

2.5.1 – AES67 Audio Network Note

For successful deployment of Attero Tech’s AES67 enabled
products, it is necessary to insure the AES67 audio network is
properly configured. A Quick Start Guide for AES67 Audio
Networking is available from the Attero Tech Customer Portal at

https://portal.atterotech.com/home/?v=files/560321a2b075c

As setup needs may vary by product, it may also be necessary to
check with the AES67-enabled product manufacturer as well.

2.5.2 – Using on a Redundant Network

The DM1 is setup for use in a redundant network out of the box.
In this mode the DM1 effectively has two separate network
connections, each with its own unique IP address. Both IP
addresses also need to be on completely different subnets.

By default, both ports of the DM1 in redundant mode will get their
own IP from a DHCP server if one is available. If not, the interfaces
will fall back to a local link address. For the primary port, that will
be in the range 169.254.x.x. For the secondary port, that will be
in the range 172.31.x.x. Static addresses may be assigned to one
or both interfaces using Dante™ Controller.

.

Connecting both the primary and secondary connections of any
Dante™ device to a network setup for redundancy *WILL* cause
network problems if the device not configured in “Redundant”
mode. As only the primary interface is required for initial setup,
if there is any doubt as to what configuration *ANY* device on the
network has, it is recommended only the primary ports of all
devices be connected to the primary network and all secondary
port connections are left disconnected. Once all devices that
support redundancy are confirmed as being configured in
“Redundant” mode, the secondary ports of all the Dante devices
can then be attached to the secondary network.

For the DM1, when connecting the primary Dante™ network,
either the primary SFP port or the primary RJ45 port can be used.
Similarly, when connecting the secondary Dante™ network, either
the secondary SFP port or the secondary RJ45 port can be used.

*Note: The connections to the primary and secondary Dante™
networks don’t have to use the same type of port on the DM1.
They may be mixed so using a primary SFP connection and an
RJ45 secondary connection or vice versa are both perfectly
acceptable.

Once connections to the main primary and secondary networks
have been made, the unused ports can be used to create a daisy
chain to a nearby device. Simply connect the spare primary port
to the primary port of the nearby device. To maintain full
redundancy, the spare secondary port should also be connected
to the secondary port of the nearby device.

Figure 7 - "Redundant" mode with daisy chaining

*Note: There are limitations using daisy chaining due to the
additional switch hops of a daisy chained switch/device in a
Dante™ network. While daisy chaining can certainly offer the
installer some benefits, careful consideration should be given as
to whether daisy chaining is suitable for any given application.

Figure 6 –"Redundant” mode, no daisy chain

2.5.3 – Using on Standalone Network

The DM1 supports both redundant mode and standalone mode
(indicated as “switched” mode in Dante™ Controller). If the DM1
is being used in a standalone network, running the DM1 in either
“Redundant” or “Switched mode is perfectly acceptable and will
work so even though the DM1 is setup in “Redundant” mode by
default, it can and will work happily in a standalone network
without changing anything. However, only the primary SFP port
or primary Ethernet port of the DM1 may then be connected to a
standalone Dante™ network.

*Note: Connecting either secondary port to a standalone Dante™
network while the DM1 is still set in “Redundant” mode will cause
problems due to the IP address setup of the secondary ports
having completely different IP addresses. Therefore this should
be avoided.

Figure 8 - "Standalone" connection in “Redundant” mode

For full flexibility in a standalone network, the DM1 should be
reconfigured to “Switched” mode. This is easily done by
connecting one of the primary ports to the standalone Dante™
network and then using Dante™ controller to switch the mode.

Figure 9 - "Standalone" connection in "Switched" mode

In “Switched” mode, the DM1 reverts to using a single internal
network connection with a single IP address. The concept of
primary and secondary ports become irrelevant and all of the
ports (both SFP and RJ45) are connected together on the same
network essentially turning the DM1 into a regular four port
network switch.

In this mode, the Dante™ network can be connected to any of the
four ports. Any unused ports may then be used to connect other
devices in a daisy chain. As the DM1 is acting as a switch, other
devices connected to the DM1 must then count the DM1 as a
switch hop.

Panel application. This is available from the customer portal
section of our website. Details of those features are shown in
the help documentation for unIFY Control Panel.

Some features of the device are operated from the various
controls on the front panel such as the main display.

3.1 – Display View Operation

During power up the display will show the Attero Tech logo. Once
the device is running, the display will switch to showing a normal
view. If there are any problems, the display will indicate a POST
(Power-On Self-Test) error. If this happens contact Attero Tech
technical support.

Once up and running, the front panel can show various different
views and is used to control a number of DM1 features. To save
power, the display will turn itself off after 30 seconds of inactivity.
To activate the display again, press either of the knobs to activate
their buttons or the monitor select button. The Display Timeout
timer can be adjusted in unIFY Control Panel.

*Note: Turning a knob will NOT turn the screen back on. It must
be a button push.

Navigating the views on the display is achieved using the “Menu
Nav” knob. Rotating this left or right will step through the various
views available. If the front panel lock has been activated by
unIFY, the panel lock icon will be shown in the upper right hand
corner of the display and while the “Menu Nav” knob can still be
used to rotate the different views no further action can be taken
on any view.

3.1.1 – Dante™ RX Monitor Levels

Each individual Dante™ channel and analog input has its own
view. The meter itself is shown in the horizontally across the main
part of the view from left to right. The name of the current
channels meter being shown is displayed in the upper left hand
corner. The name in parenthesis that follows the name is the
channel name that this channels is identified by on the Dante™
network. This view can also be used to select the monitor output
if the front panel lock is not active. To do so, with the desired
channel on view, click the “Monitor Select” button.

In Stereo Mode, the meters will be paired in L/R channels.

3.1.3 – Monitor Out Level View

There are two views for bank metering. The main part of each
bank view shows meters for each Dante™ input in that bank. This
view can be used to select the monitor output if the panel lock is
not active by pressing in the “Menu Nav” button. This activates a
cursor that can be scrolled used the knob to select one of the
visible channels. Once the desired channel is selected, press the
separate “Monitor Select” button and that channel will when be
routed to the speakers/headphone outputs.

3.1.2 – Channel Metering Views

1315 Directors Row Suite 107 Fort Wayne, IN 46808 ⁞ [phone] ⁞ www.atterotech.com

The Monitor Out Level View shows the level and gain settings for
Analog Outputs 1 and 2. The name of the current channels meter
being shown is displayed in the upper left hand corner.

Pressing the Menu/Nav knob will allow adjustment of the
respective output gain level. The meter will display in a split view,
the top being the output gain level being adjusted while the lower
is the current monitor speaker level.

In Stereo Mode, the meters will be paired in L/R channels
representing the output levels. Both meters will adjust with the
gain parameter.

Page 11

3.1.4 – Network Info View

3.1.8 – Identify

The Network info view shows the IP addresses and link speed of
the DM1’s interfaces. In redundant mode, both a primary and a
secondary interface will be shown. The primary port speed will
always indicate the faster of the two possible primary links if they
are both used. The same is true the secondary port speed if both
secondary links are used.

In switched mode, only one interface with its IP address is shown
and the speed indicated will be the fastest speed of any of the
four possible links.

3.1.5 – Dante™ Info View

The Dante™ info view shows information about the Dante™ setup.
The device Dante™ name, its port mode and the devices clock
sync status are all shown. The Dante™ name is name the device
identifies itself as on the Dante™ network. The port state shows
if the device is in either redundant mode or switched mode. The
clock sync indicates whether the device is the “Master” clock for
the system or if it’s a “Slave” to another device. A state of “No
Sync” may indicate a possible problem with either the device or
the network.

3.1.6 – Version View

The “Identify Device” option allow devices on the network to be
visually located. This feature will flash the Status/Power LED, and
display the above message on the front panel display of the
selected device in unIFY Control Panel. See the unIFY Control
Panel manual for more information on using this function.

*NOTE: On Synapse devices, the front panel controls will not
operate until the Identify function is disabled.

The Version view gives version information about the various
parts of the device.

3.1.7 – No Network

If the DM1 becomes disconnected from the Dante network at
any time, that will be indicated on various views. The metering
views will show a “No Network” message while the Network view
will show “No Network” for all indicated interfaces.

3.2 – Audio Monitoring

The DM1 is equipped with two onboard options for monitoring
incoming signals:

o Integrated front panel speakers
o Headphone output

There are two modes for Dante™ monitoring:

o Standard Mode
o Extended Mode

All monitoring modes support mono or stereo capability. In mono
mode, a single selected channel is routed to all outputs. In stereo,
the left/right audio outputs receive independent audio
assignments.

3.2.1 – Speaker Monitoring

The DM1 is equipped with speakers integrated in the front panel
to monitor audio signals in the device. The currently selected
channel for monitoring is shown in the bottom left corner of any
of the metering views. Selecting a channel can be done from any
of the metering views. The speaker output has both volume and
mute controls available.

3.2.2 – Jack Detect Mode

The DM1 internal speakers support a user configurable jack
detect mode. If enabled, the speakers will automatically be
muted if a headphone plug is connected. If disabled, the
speaker output will remain active regardless of connected
headphones.

3.2.3 – Headphone Monitoring

The DM1 has a headphone output that can be used to discretely
monitor audio signals in the device. The currently selected
channel for monitoring is shown in the bottom left corner of any
of the metering views. Selecting a channel can be done from any
of the metering views. The headphone output has both volume
and mute controls available.

3.2.4 – Volume Control

The current volume level is indicated in the lower right corner of
the display on any of the metering views. The volume is controlled
with the monitor volume knob just to the right of the headphone
output jack itself. Turning the knob clockwise increases volume
while turning it counter-clockwise decreases the volume level.

3.2.5 – Mute

The volume knob also acts as a mute control. The state of the
mute is indicated by the mute LED just to the left of the volume
knob. The LED will be red while the mute is active and off
otherwise. To toggle the mute state, push the volume knob to
activate its button.

3.2.6 – Monitor Input Select

The active monitor source is selectable from the front panel for
either incoming Dante™ channels, or the local analog line inputs.

3.2.7 – Dante™ Monitoring

Two modes of Dante™ monitoring are available based on
application needs

3.2.7.1 – Standard Mode

In standard mode, the DM1 allows user selection from any of up
to 32 Dante™ audio channels. In this mode, audio is directly
assigned using Dante™ Controller to each of the 32 DM1 Dante™
RX channels. In stereo mode, audio is routed in channel pairs to
the audio outputs.

Channels are navigated and selected from the front panel controls
once they have been assigned.

3.2.7.2 – Extended Mode

In extended mode, it is required to first pre-configure a list of
monitoring channels using unIFY Control Panel. The channel list
can contain up to 128 total mono audio channels, or 64 pairs in
stereo mode. It is not necessary to enable all channels. Friendly
names can be used to identify monitoring channels.

Channels are navigated and selected from the front panel controls
once they have been assigned. Only enabled and assigned
channels are available on the front panel for monitor selection.

Page 13

3.3 – Factory Reset

Should it be necessary, the DM1 has a factory reset option.
Activating it affects both Dante™ and non-Dante™ settings of the
device. All Dante™ settings are reset including device name and
channel names, the Ethernet port mode will be defaulted back to
redundant mode and the IP address setup will be reset to get an
IP address dynamically.

The factory reset switch is accessed through a small hole on the
front panel. The active the factory reset insert a paperclip or small
screw driver into the factory reset hole and press and hold the
factory switch for five seconds. Once the switch has been in for
long enough, if the screen was active, the screen will blank,
releasing the switch after 5 seconds will then start the factory
reset process.

3.4 – Firmware Updates

If a firmware update for the DM1 is released, it may be applied in
the field by the end user or installer. The update process takes
advantage of the smart firmware update tool in unIFY. The unIFY
Control Panel application is available from the customer portal
