Device Installation

Mounting
The case for the D32o 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 downloaded from the Documents section of the Synapse D32o product page.

Audio Connections
All connections to the Synapse D32o should be made before the power is applied. Attach audio destinations to the analog audio outputs. 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.

• Balanced Output to Balanced Input
• Balanced Output to Unbalanced Input

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: It is recommended to attach the optional 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.

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.

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

Using on a Redundant Network
The D32o is setup for use in a redundant network out of the box. In this mode the D32o 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 D32o 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 D32o, 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 D32o. 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.

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.

Using on Standalone Network
The D32o supports both redundant mode and standalone mode (indicated as “switched” mode in Dante™ Controller). If the D32o is being used in a standalone network, running the D32o in either “Redundant” or “Switched mode is perfectly acceptable and will work so even though the D32o 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 D32o may then be connected to a standalone Dante™ network.

Note: Connecting either secondary port to a standalone Dante™ network while the D32o 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.

For full flexibility in a standalone network, the D32o 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.

In “Switched” mode, the D32o 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 D32o 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 D32o is acting as a switch, other devices connected to the D32o must then count the D32o as a switch hop.

Device Operation

Certain features of the D32o such as channel mutes, output level, and front panel lockout are controlled using unIFY Control Panel application. 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.

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 D32o 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.

Bank Metering Views

There are two views for bank metering. The main part of each bank view shows meters for each analog output 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 headphone output.

Channel Metering Views

Each individual output channel 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.

Network Info View

The Network info view shows the IP addresses and link speed of the D32o’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.

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.

Version View

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

No Network

If the D32o 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 link” for all indicated interfaces.

Headphone monitoring
The D32o has a headphone output that can be used 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 headphone output has both volume and mute controls available.

1. Headphone Volume
   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 output jack itself. Turning the knob clockwise increases volume while turning it counter-clockwise decreases the volume level.

2. Headphone Mute
   The headphone 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. Identify
   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.

Factory Reset
Should it be necessary, the D32o 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.

Firmware Updates
If a firmware update for the D32o 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 latest firmware .SFU files can be downloaded from the Attero Tech Product Firmware page on the QSC website.
To apply the update, download the appropriate SFU file for the D32o, select the smart firmware update option under the Tools menu and follow the instructions. Further assistance for doing updates is provided in the unIFY Control Panel manual.

Third Party Control
The D32o offers some support for real time third party control. Information on the commands the Synapse D32o supports, as well as details of how to use the 3rd party UDP interface are available for download from Synapse D32o product page on the QSC website.
