Page 11: Introduction And Key Features
U‐Hub USER GUIDE Introduction and Key Features Introduction The Martin Audio U‐Hub is an Ethernet to U‐NET bridge equipped with analogue and AES3 digital audio transport. It facilitates PC connection and VU‐NET™ software control of MLA Series arrays and subwoofers via their inbuilt proprietary U‐NET network. Key Features  Ethernet to U‐Net bridge  IP addressable (static and dynamic)  Analogue and digital audio transport  Designed to work with DX4.0 loudspeaker processor for Dante™ digital audio distribution Converting TCP/IP to U‐NET protocol, U‐Hub allows MLA Series enclosures to self‐address and identify their position within an array, as well as supporting a simple‐to‐use redundant loop. With U‐Hub, an MLA Series system with onboard U‐NET can be seamlessly integrated into a TCP/IP network and controlled via VU‐NET software. When used in conjunction with the Martin Audio DX4.0 networked system controller, U‐Hub can connect audio and network to an MLA Series system with a single cable via a Dante™ digital audio network. U‐Net Connections The U‐Hub features two U‐Net ports and two pairs of parallel links to enable neatly loomed network cables to be used going to and from several arrays. The U‐Net connections are available on 8‐pin ODU connectors. In common with standard Ethernet data, U‐Net only uses four of the available 8 pins allowing balanced analogue or AES audio to be fed down two or the ‘spare’ cores thus greatly simplifying system wiring as an independent audio cable is no longer required. U‐Hub User Guide V1.0 10 ...
Page 12: Block Diagram
U‐Hub USER GUIDE Block Diagram This diagram shows the essential features of the U‐Hub, highlighting how the audio feed from the rear panel inputs is combined onto three of the U‐Net connections. U‐Net is run as a redundant loop, all U‐Net enabled products have two ports. Port 1 on the U‐Hub would be connected to port 1 on the first device, port 2 on this device would link out to the next device and so on with a final link back to port 2 on the U‐Hub to complete the loop. This allows the system to continue working seamlessly in the event of a cable being damaged or inadvertently disconnected. Data will simply flow in the opposite direction to allow continuous communication. Audio connections are combined with the network feeds. Audio input 1 is connected to a pair of spare connections in the U‐Net port 1 ODU. This would usually be used as the “send” to the first array. A return from the array would be connected to the first link in connection. Audio 2 is combined with the second ODU in the linked pair allowing audio to be fed to a second array, a side ...
Page 13 U‐Hub USER GUIDE Audio input can be direct from a console or from a DX4.0 processor used as a matrix. Three audio feeds – each either balanced analogue or AES EBU digital‐ are connected to the three audio inputs on the rear of the U‐Hub. The first of these is combined onto the U‐Net Port 1 which is connected to the first cabinet of the main array via a PWAXXXXX U‐ Net to U‐Net + Audio adaptor which splits the feed from the U‐Net cable to a U‐Net only cable and an AES spec audio cable terminated in a standard 3‐pin XLR. The XLR is connected to the audio input. The audio is daisy chained between cabinets using standard audio link cables. When the final network cable is routed back to the U‐Hub it is terminated using the first of the link pairs. The link pairs link the network connections (first two twisted pairs) but NOT the audio meaning that the link out can be used to route a completely independent audio feed connected to the Audio 2 input up to the side hang in the same way. The return from the side hang goes to the second link pair input with the output also carrying audio input 3 to feed the sub array. Finally, the last network connection goes from the final sub back to port 2 on the U‐Hub to close the U‐Net loop. U‐Hub User Guide V1.0 12 ...
Page 14: Audio Connections
U‐Hub USER GUIDE Audio Connections Input Connections For each audio input there is a female XLR connector for analogue or AES signals. The HOT, + or ‘in phase’ connection should be made to pin 2 of the XLR connector. The COLD, ‐ or ‘out of phase’ connection should be made to pin 3 of the XLR connector. Pin 1 of the XLR connectors is internally connected to the chassis. The shield of the input cable should always be connected Pin 1 of the XLR to ensure that EMC performance and regulations are met. Using unbalanced connections Please note that the use of unbalanced connections is not recommended, however when connecting the U‐Hub to an unbalanced audio source, the signal conductor should be connected to XLR pin2. The ‘Cold’ conductor or cable screen should be connected to XLR pin 1 with a short connection made between pin 1 and pin 3. U‐Hub User Guide V1.0 13 ...
Page 15: U-Hub Network Connections
U‐Hub USER GUIDE U‐Hub Network Connections U‐Hub features a standard RJ45 Ethernet port on the rear panel using a Neutrik Ethercon connector. This is wired using the standard Ethernet wiring protocol so any off the shelf CAT5E or better network cable can be used to connect the U‐Hub to your Ethernet network. There are two front panel mounted U‐Net ports for connection to the U‐Net enabled devices in your system. These use ODU connectors to the LEMO high speed data series pattern. Wiring configuration is as follows; ‐ The two pairs of linked ODU connectors are wired as shown in the block diagram. Pins 1, 2, 3 & 6 are linked together, pins 4 and 5 on the link out connectors have the audio signal from the corresponding audio input. The same cable wiring configuration should be used for all network connections. U‐Hub User Guide V1.0 14 ...

Page 18: Introduction
U‐Hub USER GUIDE Introduction Connect Power to the U‐Hub Connect a power source to the U‐Hub using an IEC cable and secure using the retaining clip. Connect all input and Network cables. Input cables should be balanced XLR using 3‐core cable with a shield. Most signal processing and mixing products also use XLR connections, so the cable can be a male to female XLR or “microphone” cable. Network Connections should be made using ODU U‐Net cables or adaptors available as accessories from Martin Audio. IP Selection The U‐Hub can communicate over the ethernet network which has been configured for static or dynamic IP. The default is dynamic IP where the network has a DHCP server to assign individual IP addresses to all nodes detected on the network. This is extremely straightforward for a plug and play system which is why Domestic routers are configured to act as a DHCP server by default. Static IP removes the requirement for a DHCP server on the network so is frequently the choice for more advanced ...
Page 19: Accessories
U‐Hub USER GUIDE Accessories Cables A full range of U‐Net cables in various lengths are available for connections within an MLA series system; ‐ All cables use Belden 1305A tour grade CAT5E cable and feature the 8‐pin ODU connector which is fitted with a unique over‐ moulded strain relief making them incredibly robust. The part numbers are as follows; ‐ 800mm PWA00038 Used to link between MLA or MLA Cabinets in an array 3m PWA00039 User to link MLX, DSX or MSX Subwoofers 5m PWA00051 General purpose cable, often used to link from a U‐Hub to the first subwoofer where the racks are in close proximity to the subs 15m PWA00063 General purpose cable, often used to link from a U‐Hub to the first subwoofer in an array. 35m PWA00040 Most commonly used as part of an array loom to go from a rack up to a flown array and back and as cross‐stage Ethernet links 50m PWA00077 Extra‐long Array looms. 75m PWA00052 Supplied on a cable drum, used for Ethernet connection to Front of house or extra‐long cross stage Ethernet links on large festival stages. 125m ...
Page 20: Adaptors
U‐Hub USER GUIDE Adaptors There are several adaptors available to assist with cabling up a system; ‐ PCX00048 This is a U‐Net coupler for extending cables. It is housed in a Neutrik D shell Barrell and has an ODU connector at each end wired together. PCX00043 This is housed in an identical Neutrik housing to the U‐Net coupler but has an EtherCon connector at one end and ODU connector at the other. This allows to mix the cable infrastructure between ODU cables and low cost CAT5E cable which would be a more cost‐effective solution for installed systems. PWA00056 This is a 10m CAT5E cable terminated one end in an ODU connector and the other in an RJ45 connector. As above this offers a cost‐effective solution for certain applications. Audio/U‐Net Splitter The U‐Hub audio integration features will allow audio and network signals to be fed to an array using a single cable. To split the combined U‐Net and audio signals the dedicated adaptor assembly part number PWAxxxxx is used. This receives the combined U‐Net and audio feed from the U‐Hub and splits it into independent ODU and XLR cables to connect to the U‐Net port and audio input on all MLA series products. U‐Hub User Guide V1.0 19 ...
Page 21: Vu-Net
U‐Hub USER GUIDE Vu‐Net Introduction Vu‐Net is the application used to connect to a U‐Net enabled device such as the Multicellular family of products, the DD12, PSX, CDD Live, iKon amplifiers or Merlin processor. Connection to the cabinets and processors is achieved using the U‐Net network protocol. Vu‐Net is used to monitor and control the system, EQ optimisations for multicellular arrays are uploaded from the program and cabinet firmware is checked and updated. Vu‐Net is supplied ready installed on the Panasonic tablet PC supplied with MLA and MLA Compact systems. It is an optional method of control for full use of MLA Mini, DD12, PSX and CDD Live. Menus Before we look at the design process that is used with a system it is worth taking a look at the file structure which we will refer back to throughout the chapter. When you run Vu‐Net you will see the following Window; ‐ This is a blank screen with only ‘New Project’ and ‘Open Project’ active prompting you to start by using one or the other. Start by clicking on ‘New Vu‐Net project. You will see the following window; ‐ Type a name for your project and select a suitable file location. As with Display 2.1 we would recommend creating one folder for all related files for a given event. U‐Hub User Guide V1.0 20 ...
Page 22: Window Components
U‐Hub USER GUIDE Once you have selected an appropriate name and file location click finish and a new project will be created; ‐ You will notice that the top left of the main window has your project name and a number of options on the toolbar are now available. Window components The window has a number of distinct sections with their own function; ‐ Menu and Toolbar Along the top of the window is a standard file menu and tool bar which gives quick access to a number of functions; ‐ File U‐Hub User Guide V1.0 21 ...
Page 23 U‐Hub USER GUIDE The File menu controls all file management tools. The ‘New’ duplicates this function on the tool bar and is how you create a new project. Note that you cannot have several projects open simultaneously. If you select 'New' with another project already open you will see the following Window; ‐ ‘Open’ enables you to open a project you have previously created and saved. As Vu‐Net does not have an auto‐save function it is wise to save your work at every step as is good practice for any application. ‘Close’ closes the presently active project. ‘Save’ is the standard Windows function to save the project, if it is the first time you have saved the project a window will appear giving you the opportunity to give the project a name and to choose a convenient file location. As with Display 2.1 it is sensible practice to save the file in a folder dedicated to a specific event. All subsequent Saves will overwrite the existing file. As shown, the keyboard shortcut Ctl+S can be used to save a project. It is a good idea to frequently save your work. Vu‐Net files are saved with a .vup file extension. ‘Save As’ gives you the facility to save your project with a different file name, retaining the original project. This could be useful if you wanted to try something but still have the option of returning to your original project file. 'Recent Projects' lists all VU‐NET projects recently opened making it easy to find a project you may need to re‐open. ‘Print’ will print the system layout in the main system overview window. ‘Exit’ will close the application Edit The Edit menu has a number of functions available; ‐ U‐Hub User Guide V1.0 22 ...
Page 24 U‐Hub USER GUIDE Note that additional edit menu items are displayed depending on which active devices have been selected in the System diagram overview, Product such as MLA and MLA Compact have Presets that can be loaded or saved and zones that can be defined, other devices such as DD12 or CDD‐Live have Snapshots for loading or saving. ‘Select All’ selects every item on the main project window. All selected items will show four square black dots in the corners around the object or objects. Preferences Preferences have some important options for how Vu‐Net operates; ‐ Calculations: The first option is labelled ‘Calculations’ and allows you to select the venue temperature in steps of 5⁰. This is used when the option is selected in the Merlin Controller to read delay figures as a distance as opposed to time. The temperature adjustment calculates the delay time according to the speed of sound at that temperature. Select the desired temperature using the drop‐down box or an exact value may be typed directly into the box and click ‘Apply’. Note that if you have a Merlin open in the project window the change will not be visible until you close it and reopen. Firmware update: The next option is Firmware update; ‐ U‐Hub User Guide V1.0 23 ...
Page 25 U‐Hub USER GUIDE This shows the web URL for the system to search for firmware updates which will be covered in the Firmware chapter. This should not be changed unless notification is received from Martin Audio to do so. If, however it accidentally gets changed or deleted it is possible to reset all Default parameters by clicking on the Restore Defaults button. Note that this restores ALL Preferences so any that you wish to retain will have to be re‐entered. Help: Next are options for how the Help menu is displayed; ‐ By default, the help window is displayed in a dedicated help browser, but you can select it to open in your default Internet Browser. Context help which responds dynamically to objects selected can be displayed as a window on the application or as an “Infopop” Help includes a sub‐menu for accessing help from remote infocenters. This is not currently operational and will be a future upgrade. ...
Page 26 U‐Hub USER GUIDE Network: The Network option is an important section for determining how devices are found on the Ethernet network; ‐ Running the application off line will display a blank window. When you have one or more U‐Hubs connected (usually at least two for MLA and MLA Compact systems) their unique IP address will appear listed in the bottom ‘Available IP addresses’. You can set an IP address Filter in the smaller window which will search only for IP addresses within the range of values between the two entered which should be separated with a comma; ‐ This could be used if you have two systems running on the same Ethernet network and need to control them independently. Only devices with their IP address set to values within the filter range will be found and the system will work completely independently as if there were no other devices on the network. ...
Page 27 U‐Hub USER GUIDE Note that if you are connecting to MLA Mini, DD12 or PSX via their integral USB port, no IP address will be visible. This function is only applicable to networks supported by U‐Hubs, Merlins or Ethernet connected devices such as the CDD Live range. User Interface: The final option in the Preferences window is User interface; ‐ This allows customisation of certain functions within the application. Increment Values; ‐ These allow the default increment values for both Gain and Delay to be changed as required. The default for Gain is 0.5dB but the options are for increments of 0.1, 0.2, 0.25, 0.5 or 1dB. For delay, the default is 25ms, the options are 0.1, 0.2, 0.25, 0.5 or 1ms. Windows Power Option; ‐ Allows Vu‐Net to prevent Windows from implementing changes to the power settings that can affect network operation. This should be left checked unless there is a very specific need to do otherwise Finally there are a number of options for how the system diagram is displayed; ‐ U‐Hub User Guide V1.0 26 ...
Page 28 U‐Hub USER GUIDE This is intended to reduce the number of lines on the System Diagram overview which may get cluttered in large systems with a high number of devices. Finally you can select whether CDD‐LIVE and CSX‐LIVE products appear in a single editor window; ‐ Tools The tools menu; ‐ This has three important functions for system operation. Preset Loader is used to upload EQ optimisations into the arrays. Firmware Update Wizard is used to check and upload the latest firmware into the system components. MLA/MLD Conversion Tool is used to convert the amplifier modules used in MLA and MLD cabinets from one type to another. Mechanically and electrically these are identical, they simply need a firmware conversion, so the system is aware of what type of enclosure they are powering. An MLD module can be converted to an MLA or more commonly an MLA module to an MLD. Window The Window menu is used to determine which sections of the project window are displayed; ‐ The System Diagram is always visible, but the other windows can be closed and reopened as required. By default, they are all open but if closed they can be reopened by selecting them from the Window menu. The Reset Perspective option will restore the project layout to the default view. Help The help menu has a number of options; ‐ U‐Hub User Guide V1.0 27 ...
Page 29 U‐Hub USER GUIDE 'Welcome' opens the splash screen that is displayed when Vu‐Net is run for the first time; ‐ The lines ‘Go to Martin Audio website’ and Go to MLA website are hyperlinks and clicking on them will take you directly to the respective website if your PC is connected to the internet. The window can be closed in one of three ways; ‐ Click on ‘Start using the software’ Click on the x in the Welcome box in the top left of the window; ‐ Click on the drop down arrow in the top right of the window and select ‘close’; ‐ Any of these will close the welcome screen to reveal the project window. User Guide: This is a link to this very guide slightly rearranged for use in the field when running the software. The contents page features links directly to the specific subject so you can very quickly navigate to where you need to be to discover the answer to something you don't fully understand. U‐Hub User Guide V1.0 28 ...
Page 30 U‐Hub USER GUIDE Essential Reading: This opens a pdf document that outlines the new features in the latest version of Display 2.2 and how they affect their implementation in Vu‐Net. Send Feedback: opens a communication window which gives you an opportunity to communicate any issues or ideas for new features straight back to Martin Audio; ‐ Note that an internet connection is required for your Feedback to reach Martin Audio. Tool bar The toolbar has a number of icons which offer either quicker access to commonly used functions from the file menus or specific functions which are essential to system set up and operation. The first 4 icons are file management tools; ‐ These are New Project, Open existing project, Save and Save As. The next group are graphic alignment tools for effortlessly making your system diagrams look neat and tidy; ‐ The first, second, fourth and fifth of these are only active when two or more components are selected; the third is only active when one or more Merlin controllers are selected. The first icon aligns all selected components horizontally on the page. The second aligns all selected objects vertically. The third tool is used with the Merlin. When a system is discovered its network connections are drawn in place. The two U‐Net nodes on the Merlin, usually run as a closed loop will go off to the first cabinet in the array and back from the last cabinet. Depending on the layout of your system diagram this may mean that network cables are crossing over looking a little messy. This tool reverses the two network nodes in the diagram to try and neaten the diagram. Note that it is only adjusting the graphic representation; it is not making any electrical changes to the U‐Net nodes in the Merlin. The final pair of icons will reverse the position of any selected objects. Perhaps you have an MLA array to the right of an MLX array and you would rather position them round the other way, you just select both arrays and click on the ‘Reverse order horizontally’ button and their order will be reversed maintaining their connections and keeping them aligned. Likewise, if you ...
Page 31 U‐Hub USER GUIDE Discover Devices is the method by which U‐Net connects to all system components once all hardware connections have been made; ‐ This will interrogate the U‐Net network and find all connected devices opening Wizards for each type of device; MLA & MLD, MLX, MLA Compact, DSX, MLA Mini, MSX, DD12, CDD Live and Merlin. All devices on the same U‐Net loop will be grouped together by type by the discovery process. Note that Vu‐Net will discover devices regardless of how they are connected, either directly by USB in the case of MLA Mini, DD12 or PSX, via Ethernet for CDD Live and CSX Live, or over a U‐Net loop via a Merlin acting as a network bridge Master Overview; ‐ ...
Page 32 U‐Hub USER GUIDE Allows you to adjust the system diagram size to suit the complexity of the system on your PC display. The ‘‐‘ and ‘+’ buttons will decrease or increase the zoom in increments of 25%. Alternatively, you can use the drop‐down box to select either 10%, 25%, 50%, 100%, 125%, 150%, 200%, 300%, 400%, 600% or 800%. Particularly useful are ‘Page’ which will zoom to the maximum size that the page will allow, ‘Width’ which will zoom to the maximum width of the diagram and ‘Height’ which will maximise the size to fit the height of the diagram. Mute is essentially an “emergency" function if something is causing severe noise through the system you can click on the mute button; ‐ This will bring up the following window; ‐ As you can see it is a very drastic measure which will shut down the entire system which is why it should be considered as an emergency measure only and not an everyday means for muting the system. If you are sure you wish to proceed you can select ‘Yes’ if not click on ‘No’ and the window will disappear, the audio will remain routed. This function mutes every input and output on connected Merlins and every zone on all arrays. Once used there is no global un‐mute, all Merlins and arrays will have to be individually un‐muted. Note that Show Modes does not change operation of the System Mute, the confirmation window will always appear. Our advice is never to leave a system muted within Vu‐Net, always use a mute that can be defeated manually such as a Merlin output. If a system has been muted within Vu‐Net and for some reason you lose network connectivity you will be unable to un‐ mute and will have an unusable system! System Disconnect This will disconnect the project from the hardware in the system. A Window will pop up giving you a selection of options; ‐ As you can see, once you are disconnected from the system you are unable to make any changes to the project, this is to ensure compatibility and accurate synchronisation when you reconnect. You have the option to reconnect straight from the window or can close the project with or without saving. Finally, you can minimise the project. This is particularly useful if you have disconnected to switch from a Wi‐Fi to a hard‐wired connection, having minimised to can access the PC network setting to make ...
Page 33 U‐Hub USER GUIDE Once Disconnected the Disconnect button will change to reconnect also allowing you to reconnect to the project; ‐ Project Workspace The workspace is divided into several sections which can each be opened, closed or in the case of the ancillary section, “detached" as a floating window. By default, the workspace appears like this; ‐ There are three main sections, the first is the system diagram; ‐ U‐Hub User Guide V1.0 ...
Page 34 U‐Hub USER GUIDE This window will show all array components on the network and is used for all configuration changes and system monitoring. The palette on the left is used to manually enter system components when working off line (in normal use, Device Discovery is used to find all connected components). If you need to maximise the workspace the palette can be minimised by clicking on the white triangle in the top left corner of the palette; ‐ The overall size of the System Diagram can be increased or decreased by clicking and holding on the gap between its right‐hand edge and the left‐hand edge of the other windows. You can then drag either left or right to adjust the relative sixes of the windows. Alternatively, the white drop‐down arrow gives you the option to maximise the screen. The other windows will not be ...
Page 35 U‐Hub USER GUIDE as in the picture above. Arrays will have a further arrow which if clicked will show all individual cabinets. This screen grab shows an enlarged project window in which the User Guide system has been expanded and one of the MLA arrays and one of the MLX arrays have also been expanded; ‐ The final window by default has Properties and Outline available but by using the ‘Show View’ option in the Window menu, you can also select Network Status. This shows all three options available; ‐ Any of the three options can be viewed by clicking on the relevant button. As with the Project window any of the selected options can be detached as a floating window, maximised or closed by clicking on the white arrow. If all options in the window are closed the project window will fill the space, if that is also closed the Project window will fill the space. The Properties window will show the properties for any element selected in the System diagram. The example above shows the properties for a Merlin in an off‐line project. There are a number of options available for the Properties display selected by the icons in the top right corner of the window; ‐ U‐Hub User Guide V1.0 34 ...
Page 36 U‐Hub USER GUIDE The first pins the Property view of the selected element so it remains on view regardless of whether an alternative element or even project is selected. A second click on the icon will un‐pin the view and any new selected element can have its properties displayed. The next is the Show Categories button which is selected by default. This shows the categories for each of the properties and gives the option to display or hide any of the properties in a particular category by clicking on the small arrow leaving just the category heading. The third icon displays advanced properties for the selected element. The final icon will reset any modified properties to their default values. The Outline window displays a miniature thumbnail of the system diagram for whichever project is selected; ‐ The network status shows the status of the network connection to all elements in all projects running in Vu‐Net. This screen shot shows the network status of the elements in an MLA/MLD & MLX system (currently off line); ‐ U‐Hub User Guide V1.0 35 ...
Page 37: Working Offline
U‐Hub USER GUIDE Working Offline Before we move on to look at adding elements to projects it is important to understand the difference between working off line and normal on‐line operation at an event. When working off line the Palette allows you to drop elements into the System Diagram, you can open arrays, speakers, U‐Hubs and Merlins as you would for an on‐line system. This is useful as a means to get used to system operation in Vu‐Net but very little beyond that. Unlike some systems you CANNOT create a system design off line and connect to a system on site. When connecting to a system you have to use Device Discovery which searches all available connected devices for system elements and automatically drops them into the system diagram showing their Ethernet and Vu‐ Net Connections. This is vital as every Vu‐Net element has a unique factory set IP address which Vu‐Net records, so it can provide real‐time monitoring of the system and can display the status of every device. If for example you re‐connect to a system having used it on one day and shut down over night, Vu‐Net will be able to detect that every cabinet has been turned back on and the status of all parameters of every DSP. We will show how to introduce all available elements into a project off line but will cover ...
Page 38 U‐Hub USER GUIDE into Preferences and selecting ‘Network’ and making sure that the Available IP addresses window has an IP address for every Merlin in use with your system. If all is ok you can proceed by clicking on the Discover Devices button; ‐ Assuming everything is OK with your network connection you will see the following window; ‐ The meter bar will gradually move across until it is completely green, and all devices have been found. This may take a few seconds on bigger systems with large arrays of many cabinets. There are a couple of other windows that may appear at this stage, as well as discovering all devices on the network and identifying their type and IP address, Vu‐Net also checks their Firmware to ensure it matches the latest version stored in its ...
Page 39 U‐Hub USER GUIDE This shows a list of all connected devices found grouped into categories; U‐Hub Controllers, MLA, MLD, MLX et cetera. Each individual U‐Net network created either by a U‐Hub, Merlin or USB connected device (such as an MSX or DD12) will create an individual window with the IP address shown at the top. All devices connected to that U‐Net loop will be listed grouped by type. Next press the ‘Run Wizard’ button and an individual Wizard will run for all categories, the first will be MLA, MLD or MLA Compact; ‐ If you have more than one array of each type of cabinet on the same U‐Net loop you have the opportunity to divide them into two or more arrays as required. Use the up/down button to select the number of arrays then change the number of cabinets in ...
Page 40 U‐Hub USER GUIDE If the total does not match what Vu‐Net has discovered the numbers will be flagged in red. Click next and you will see a new window showing the array or arrays; ‐ If you have more than one array the first step is to use the ‘ALL ON’ button which will illuminate all the LED badges on the array to check that the Vu‐Net arrays match the physical deployment. If there are any errors the cabinets can be dragged and dropped to the correct positions or array. If you only have one array it is still worth flashing all LED’s to see the look on the faces of the lighting technicians when they see LED lighting over which they have no control… Next click the ‘BY ONE’ button. This will flash the LEDs in sequence from top to bottom. As the U‐Net network is bi‐directional it is entirely possible that the arrays could have been discovered starting with what is actually the last cabinet in the array. If this has happened you will see the LEDs on the actual cabinets flashing from bottom to top and you MUST click ‘REVERSE ORDER’ to get it flashing the right way up. This is essential so that Vu‐Net knows that the array is orientated the right way, failure to do this U‐Hub User Guide V1.0 39 ...
Page 41 U‐Hub USER GUIDE could result in an EQ optimisation being loaded upside down producing an array attempting to produce a coherent, flat response for an audience 30 meters or so up in the air! Next you will see the following window for any connected MLX or DSX; ‐ By default, the ‘Arrangement’ will be displayed as ‘Flown’ therefore the ‘No of columns’ field will show 1. If you click on ‘Flown’ it will toggle to ‘Ground Stacked’ and if this is how your subs are deployed you can select the number of columns to reflect in Vu‐ Net exactly how they are positioned; ‐ This could even mean making the columns equal the number of enclosures where a broadside array is being deployed; ‐ U‐Hub User Guide V1.0 40 ...
Page 42 U‐Hub USER GUIDE Once you have selected the array configuration select ‘Next’ and you will see a similar window to the one for MLA, MLD or MLA Compact; ‐ Repeat the process of flashing LED badges to ensure that the cabinets are in the correct order. If any are in the wrong position use drag and drop to reposition them. For a conventional sub stack this may not be vital as the parameters are likely to be identical for all cabinets but for cardioid or broadside arrays it is essential to ensure that they are correct so delay and other parameters applied are directed to the correct cabinet. At this stage you can also change the LED badge to flash on the rear. They are configured for the front LED by default signified by the ‘F’ on the thumbnails. Double click directly on the badge and ...
Page 43 U‐Hub USER GUIDE Once you are satisfied with the sub layout click on ‘Next’ and the synchronisation of all elements on the U‐Net loop will commence; ‐ It possible (although unlikely) that one or more element will not synchronise correctly on the first pass in which case there will be a Red ‘Fail’ in the Result column for that device. If this occurs wait until the rest of the synchronisation is finished and click on the Synchronise button for that device in the extreme right column. The device will attempt a further synchronisation which should result in a success and a green ‘OK’. A complete successful synchronisation will appear like this; ‐ U‐Hub User Guide V1.0 ...
Page 44: Device Id
U‐Hub USER GUIDE This means that all settings residing in the DSP of all components have been uploaded into Vu‐Net so you have a completely accurate picture of exactly how the system is configured on your tablet PC. You can click ‘Finish’ and a further ‘Finish’ on the Device Discovery Report window. Repeat the procedure for all connected U‐Hubs or Merlins which will all have their own U‐Net ring of elements. Once this is completed the Vu‐Net workspace will appear as shown; ‐ Device ID In larger systems with multiple U‐Hubs it is helpful to identify them individually so they can be given an appropriate name. Double clicking on the U‐Hub icon will turn the front panel name green as shown; ‐ U‐Hub User Guide V1.0 43 ...

U‐Hub USER GUIDE This will make all front panel LEDs on the U‐Hub to flash for approximately 3 seconds making it very easy to identify. Right Click menu Unlike other devices in Vu‐Net, there is no internal processing, so all U‐Hub functions are available from the right click menu which appears like this; ‐ Locate Duplicates the identification function illuminating the front panel name on the Vu‐Net thumbnail and making the LEDs on the front panel of the U‐Hub flash. Synchronise Repeats the synchronisation that Vu‐Net performs following device discovery. Disconnect / Reconnect This allows you to disconnect the U‐Hub from Vu‐Net and then reconnect IP Settings This opens the IP Configuration Window to select between Dynamic and static IP (See the IP setting chapter) Rename You can give the U‐Hub a name of your choice up to 32 characters; ‐ U‐Hub User Guide V1.0 44 ...
Page 46 U‐Hub USER GUIDE The keyboard shortcut to rename a U‐Hub is F2. Delete Removes the U‐Hub from the system. This will open a confirmation window; ‐ Click OK if you are sure or Cancel if not. IP Settings By default, the U‐Hub is set to dynamic IP so will require a Lan with DHCP present to assign an IP. In a standard MLA system this is provided by the Zone Director housed in the Master rack. The U‐Hub can be changed to Static IP for sophisticated networks which may be shared by many devices. Right clicking and selecting IP Settings opens this window; ‐ To change to Static IP click on ‘Set IP address manually: static mode’ ; ‐ U‐Hub User Guide V1.0 45 ...
Page 47 U‐Hub USER GUIDE The default static IP is the same address that can be set using the front panel IP reset switch, 169.254.19.71. This can be changed to any IP address within the range you require for your network. Once the U‐Hub has been configured for Static IP the front panel Static IP LED will illuminate.
