O-Line USER GUIDE Introduction Thank you for purchasing your Martin Audio O‐Line Micro Line array system. O‐Line delivers consistent audio coverage with unprecedented accuracy in a wide variety of architectural environments, using just one amplifier channel per array in many applications. By utilising a complement of unique, Martin Audio designed drivers, and mechanical alignment techniques, simple EQ and Limiting is the only processing required. An O‐Line module uses 2 x 89mm reflex‐loaded, mid/low radiators either side of a central strip of 5 x 14mm HF devices in a unique, patent pending arrangement with a spacing of only 21mm between each element. The result is side lobe‐free vertical dispersion from the high frequency section. The ‘cones’ of the two custom‐designed LF drivers are sculpted from an ultra‐light, stiff material and precisely follow the ideal contour of the HF horn walls (patent pending). This provides constant horizontal directivity from low mid, right up to extreme high frequencies. Rather than applying DSP to a traditional column, O‐Line’s vertical beam‐forming is achieved by physically articulating individual array modules to curve the array. The actual array configuration for a specific venue is determined by powerful optimisation software, which makes intelligent judgements about the ‘goodness’ of the array’s SPL distribution against objective target functions. O‐Line arrays are constructed by simply connecting individual modules together in column lengths of 4 to 24 units as determined by the software. O‐Line modules are finished in a neutral light grey and combine to form aesthetically pleasing, variable length arrays, of ...

O-Line USER GUIDE O‐Line Bottom Cover The O‐Line Bottom Cover Plate An O‐Line array can be finished off with the addition of the optional bottom cover which fits to the base of the lowest O‐Line module in the array to give a very neat finish. This may not be necessary for wall mounted arrays but is often essential for flown arrays where the bottom of the array is usually visible. Bottom Cover mounting detail O‐Line User Guide V3.2 40 ...
Page 42
O-Line USER GUIDE The bottom cover is fitted via the raised mounting bracket on the inside of the cover which lines up with the holes on the O‐Line bracket which are normally used to attach the linking plates. It uses the same nuts and bolts as the linking plates, you will always have a set of these left over as each block of four O‐Line Starter Kits has a set to connect to the modules underneath it. Obviously the bottom modules in an array have nothing connected to them! You will need the back cover of the lowest O‐Line module removed ready to fit the cover. Tip! Remove the covers and the orange safety clips from the bottom two modules as this will make it much easier to fit the Allen key into the bolts to tighten them up. Position the bottom cover in place under the lowest module. You will find that the mounting bracket will fit snugly between the O‐Line steel brackets and the holes will line up with the linking plate holes. Fit the spare linking plate nuts and bolts starting with the lowest two and tighten with a 4mm Allen Key and a 10mm open ended spanner. O‐Line User Guide V3.2 41 ...

O-Line USER GUIDE System wiring General Your O‐Line is delivered in blocks of 4 modules ready wired in parallel. These four‐module blocks may be separated into smaller blocks or individual modules, linked and paralleled to other blocks or modules using short link wires ‐ or series connected to other blocks or modules using the series connector PCB supplied with each four‐module block (see illustration below). The Series Connector PCB also provides an input termination. Note: White = negative, red = positive. Connections to upper and lower blocks are indicated on the circuit board Route the connection cables under the orange safety clips to avoid crushing them when replacing the covers. This allows the installer to build an array of appropriate length (we recommend 6% of each plane to be covered for good spectral balance) with electrical characteristics best suited to the Martin Audio power amplifier chosen. Amplifier choices and limiter settings The following chart shows Martin Audio power amplifier choices (indicated by dots) and Martin Audio DX1.5 or DX2 limiter settings (in red) to obtain optimal performance from the wide range of O‐Line array sizes and patch configurations possible. Single channels, two channel and four channel configurations are shown. Multi‐channel configurations are useful where zone control may be required. To avoid amplifier clipping (which dumps excessive power into the HF arrays in the form of odd‐order harmonics) it is best to choose the highest power amplifier in the range indicated. Note that power amplifiers must be set to the industry standard maximum voltage gain of 32dB (x40) with a correctly limited DX1.5 or DX2 system controller to comply with warranty conditions. ...
Page 46
O-Line USER GUIDE (This chart is repeated full‐size on the next page for easy reference) Clip Limiter settings Martin Audio loudspeakers are AES power rated. AES ratings allow for up to 6dB voltage (4 x power) instantaneous peaks. We therefore recommend that you set your DX1.5 or DX2 output channel Clip Limiters to +6dB. Controller presets? Note that we do not publish fixed presets for the O‐Line – apart from recommending a standard 60Hz high pass filter and the required limiter settings. The Display 2 software – used to optimise the array shape – also generates the controller settings required for a flat in‐situ system response or to meet your chosen house curve using the Optimise EQ function.

USER GUIDE Advanced Optimised System To create O-Line arrays you use Martin Audio's unique Display 2 software. This calculates the inter-module angles and the DSP parameters using the same numerical optimisation techniques. Its sophisticated processing using FIR filters provides remarkable system coverage. The output from Display 2 is a file (a d2p file) containing all the processing coefficients. You can upload this file to an IKON amplifier using Martin Audio's Vu-Net software.
Page 60
O-Line USER GUIDE The application is very straightforward to use taking you through a series of steps in a logical order. In fact it won’t allow you to attempt to design a system in the wrong order; steps need to be completed one after the other in the correct order making it very straightforward to design an array that will perform to its maximum potential. DISPLAY opens with a Dashboard at the top of the screen the initial view prompting you to specify your array which is the first step of the design process. O‐Line is available along with the Multicellular and Wavefront Precision families of products. You next specify how your array will be deployed, flown is the option for O‐Line, specify the number of cabinets and give the array a name. The dashboard changes to show the tabs from left and right in the order in which the design will be completed. First a 2D slice of the venue is created, the coverage within the venue is specified, the splay angles calculated. A rigging report allows you to deploy the array and whilst that is being done the EQ coefficients are calculated. Finally an SPL report gives detailed information showing exactly how the system will perform. The computer model is accurate to within +/‐ 1dB of actual measured results so the SPL tab is a reliable overview of how well your system design will cover the space. O‐Line User Guide V3.2 59 ...
Page 61
O-Line USER GUIDE The 2D slice is either drawn from scratch or you can also import a shell drawing from a previous project if you are working in a venue you have visited previously. The slice is a side view of the venue. It is drawn anticlockwise starting at the back of the stage and clicking to define the position of vertices that define all of the planes within the venue. This doesn’t have to be done accurately as you can refine the precise position of the points working from architects drawings or measurements you have taken yourself. The array is positioned and the audience region specified from start to finish. The coverage tab shows your 2D model with the planes refined into three types;‐audience in green, non‐audience in red and hard avoid in blue. Each dot represents a virtual microphone position at which the software will take response measurements using the integral computer model. The dots in the critical audience region are closer together for greater accuracy and are spaced closer together at the start of the audience region to mirror how each region is covered by sections of the array. The O‐Line User Guide V3.2 60 ...
Page 62
O-Line USER GUIDE audience offset can be edited; standing, sitting or a custom offset of your choice and each region can be edited, perhaps changing a section under a balcony from audience to non‐audience for example. The SPL profile can be modified and the environmental conditions entered to allow the optimisation to compensate for air absorption, particularly critical for outdoor events. In the splay tab you can refine the quantity and position of the array before the system optimises the inter‐cabinet splay angles and the “aim” angle for the flying frame. With the physical deployment underway you can progress to optimise the EQ. Again you can enter the environmental conditions and can balance the three goals of response in your audience region, leakage to non‐audience and the hard avoid performance. ...
Page 63
O-Line USER GUIDE By default each are given equal importance but if your application demands particular emphasis on any one of these parameters they can be given greater importance. The resolution is entered selecting any number from 8 box to 1 box. The SPL tab shows the system performance. The entire venue SPL is displayed on an index plot with frequency along the horizontal axis and position within the venue along the vertical. SPL is indicated with colour, blue being quietest moving through the colour spectrum to red which is the loudest. You can move the cursor around the Index Plot and the position is shown on the 2D slice of the venue top left whilst showing the frequency response at that position on the graph on the right. The final stage is to export your design. You can produce a printable rigging report, a wire‐frame 3D model of the array, export 3D data for use with EASE and most importantly export the project as a D2P file which can be uploaded directly to an iKON ...

O-Line USER GUIDE Vu‐Net Vu‐Net is Martin Audio's application which is used to connect to iKon amplifiers and a many Martin Audio products. This makes it possible to create a system with products from several different ranges and control and monitor them from a single software platform. Connection to iKon amplifiers is made over a standard Ethernet network using off the shelf networking products so remote access to control O‐Line systems is extremely straightforward if required. Complex systems with large numbers of amplifiers can easily be created using standard network switches, the system by default is configured with dynamic IP addressing so DHCP support will be required however a static IP configuration is also easily enabled.

For a stereo system, repeat the process selecting the next amplifier channel from which you need to drive the second array You can now return to the project system diagram, double click on the amplifiers and edit the system to suit your application, perhaps adding some delay to align subwoofers Input EQ can be adjusted to suit your preferences and to compensate for any difficult acoustics O‐Line User Guide V3.2 65 ...

O-Line USER GUIDE The output EQ is greyed out as it is used to apply the EQ created by your Display project, however the high pass filter is available for adjustment so you can determine the crossover point between the O‐Line array and subwoofers if used. Comprehensive ganging is available so you can ensure that stereo arrays remain completely identical O‐Line User Guide V3.2 66 ...

O-Line USER GUIDE Wiring Advanced Systems Wiring optimised system requires a little more system preparation and planning than a conventionally configured array. Multi‐ way speaker cable may be required depending on the size of the array and degree of resolution that has been selected in the Display 2 project. Note that each individual O‐Line module is rated at a modest 50W AES so unless cables runs are very long you can use speaker cable with a smaller than usual cross section, 1.5mm² or even 1mm² may be acceptable. This should help avoid bulky speaker cables looms for arrays with a high resolution. The following wiring diagrams are for arrays that are comprised of multiples of four modules as that is how O‐Line is sold. It is however perfectly acceptable to use arrays of any number from 1 to 32 modules. The wiring guides are intended to be used as a template, they can be scaled up or down to suit the exact size of array to be deployed. Note that where the resolution selected is not an exact division of the number of modules in the array‐ 10 modules with a 3‐box resolution for example‐ the "odd" number module(s) will always be the one(s) at the bottom so for the 10 module array, the first three at the top of the array are run in parallel, then the next three down (modules 4, 5 & 6), then the next three (modules 7, 8 & 9) with the final module at the bottom run from its own channel, therefore four channels of amplification and DSP are required (half of an iK81). 4‐Module Arrays 8‐Module Arrays O‐Line User Guide V3.2 68 ...

O-Line USER GUIDE Wiring Individual modules O‐Line is supplied in blocks of four modules which are not only physically linked but also electrically linked in parallel. This is perfect for 4‐box resolution but any other configuration you will need to modify the connections to suit your array configuration. O‐Line connections are made using red and white tri‐rated cable to the Phoenix connectors on each module. There are four connections on each Phoenix, this allows an input connection and a parallel output to make linking to adjacent modules very straightforward. The connections are positive (red) on the outside pins and negative (white) on the two middle pins. The cables supplied are run underneath the rigging brackets to keep the module wiring neat. If you need to remove a link between modules to modify the wiring the process is simple enough: As the connector is tacked in a recess under the rigging bracket, it is a little difficult to access, it is best removed with a pair of long nose pliers. There is enough slack on the connecting wires to pull the connector clear so you can access the screws in the top of the connector to loosen and remove any of the wires and to add new connections direct from an amplifier channel. You will need a 2mm flat head screwdriver. To completely remove any of the links you will obviously need to disconnect both ends of both the red and white wires. Although the wires run under the rigging bracket you should be able to pull them clear from the module which is best done again using long nose pliers. Don't forget to firmly push home all Phoenix connectors once you have re‐configured the wiring as required. O‐Line User Guide V3.2 73 ...
