MARTIN AUDIO O-LINE (01) PDF Document

After unpacking your MARTIN AUDIO O-LINE system, examine it carefully for any signs of transit damage and inform your dealer if any is found. It is suggested that you keep the original packaging so that the system can be repacked at a future date if necessary.

MARTIN AUDIO O-LINE loudspeakers must be installed by experienced loudspeaker installation personnel using the full installation kit provided. The installer is responsible for ensuring compliance with all relevant local, national, and international electrical, fire, and building safety regulations.

Yes, every MARTIN AUDIO O-LINE loudspeaker must be fitted with a steel safety wire. This can be fitted between an attachment bracket (provided) and a suitable supporting structure.

Note: PZ = Pozidrive, S = Straight/Flat head

Each pack of MARTIN AUDIO O-LINE modules comprises the following parts:

• 4 x O-Line Modules (Linked at 0°, rear covers fitted)

• Series Linking PCB

• PCB Screws

• Link Plates

• Safety Clip

• Martin Audio Badge

• Linking Pins

• Shade

• Link Nuts & Bolts

The self-adhesive shade may be used to prevent down-lighting from shining down through the grilles in architecturally sensitive locations. A self-adhesive Martin Audio badge is supplied to be attached to a complete array, usually placed on the bottom module.

To avoid flattening or damaging your O-Line grilles, it is strongly recommended that you keep each block of four modules in their high density foam trays during preparation.

Step 1. Take off the rear covers by removing the rear screws from each unit. If you are not using a magnetic screwdriver, cover the rear port holes with tape to prevent dropping screws down the ports.

Step 2. Press the screws into the front of the high density foam tray to avoid losing them.

MARTIN AUDIO O-LINE modules are shipped with splay angles set at 0 degrees. After determining the required splay angles using the O-Line software, set the inter-module splay angles as follows:

Step 1. Remove the rear cover.

Step 2. Remove the orange safety clip.

Step 3. Remove the linking pins from the splay angle holes. If the linking pins are difficult to remove, loosen the four link plate nuts and bolts for that module. Remember to re-tighten them after positioning the link pins.

Step 4. Angle the O-Line modules to the required splay angle, lining up the link plate holes at the required angle positions marked on the bracket (0, 1, 2, 3, 4, 5).

Step 5. Insert the four linking pins into the aligned link plate holes.

Step 6. Replace the orange safety clip after positioning all four linking pins.

Step 1. Prepare the O-Line module splay angles as indicated by the O-Line software.

Step 2. Fit the U-bracket first. There are two positions: towards the top for 3-5 degrees or towards the bottom of the bottom module for 0-2 degrees. Use the position that allows the linking pins to be fitted without being obstructed. Once the bracket is attached, fit the linking pins.

Step 3. Fit the collar to the U-bracket using the M10 x 75 bolt. Ensure the collar is oriented towards the top of the array.

Step 4. Tighten the M10 bolt so that it protrudes at least 1.5 thread turns through the lock nut but still allows U-bracket movement for easy adjustment.

Step 5. Fit the M8 x 60mm bolt loosely to the collar.

Step 6. Wire up the array and fit the rear covers, using the cut-out version for the module with the bracket.

Step 7. Fit the HAM02012 wall bracket to the wall.

Step 8. Lift the block of four O-Line modules onto the wall mounting.

Step 9. Fit and adjust the M8 x 40 bolt to set the vertical tilt angle.

Step 10. Tighten the clamping bolt (M8 x 60) after setting the horizontal angle.

Step 11. Check that the M10 x 75 collar-to-U-bracket bolt is firmly screwed into its locking nut.

Step 12. ALWAYS double-check that all orange safety clips are in place to ensure the array is safely locked together.

Assembly:

Step 1. Prepare your blocks of four O-Line modules to the splay angles recommended by the O-Line software.

Step 2. Add link plates to the lower module of the upper 4-module blocks using the link plate bolts and lock nuts.

Step 3. Fit 4-module blocks together by interlocking the tongues on the top of the lower block into the slots on the upper block.

Step 4. Add the linking pins and the orange safety clips.

Step 5. If a series connection is required, wire the 4-module blocks together using the connector PCB. Route the wires between the linking pins to avoid crushing them. Screw the PCB to the inside of the most convenient rear cover.

Mounting:

Step 6. Fit the U-bracket to the lower O-Line module first, then add the linking pins. The U-bracket position depends on the required linking pin positions (0-2 degrees or 3-5 degrees).

Step 7. Fit the main HAM03192 tie-bracket to the module indicated by the software. The bracket position and orientation will be determined by the angle setting required.

Step 8. Fit the second HAM03192 tie-bracket to the top module.

Step 9. Refit the rear covers using the cut-away covers around the tie bracket and U-bracket.

Step 10. Fit the collar to the U-bracket using the M10 cap head machine screw. Leave screws finger-tight for now.

Step 11. Load the ASF20024 wire rope into the wedge socket by placing a loose loop into the socket, looping the wire around the wedge, and pulling it semi-tight. Attach the assembly to the main tie bracket.

Step 12. Fit the top (HAM02027) and bottom (HAM02026) wall brackets onto the wall at the recommended heights.

Step 13. Lift the array and lower the collar onto the spigot on the bottom bracket. Tighten the clamp screw.

Step 14. Shackle the end of the wire rope to the top wall bracket.

Step 15. Use the wedge socket to fine-tune the down tilt of the array. Once the angle is set, add the DIN1142 rope grips for extra security and ensure everything is tight.

Step 16. Tighten the U-bracket-to-sleeve screw.

Step 17. Add a safety wire rope between the second (top) tie-bracket and a secure part of the building structure.

Step 18. ALWAYS double-check that all orange safety clips are in place.

Step 1. Prepare your 4-module blocks to the splay angles recommended by the O-Line software.

Step 2. If your array is larger than 4 modules, add link plates to the lower module of the upper 4-module blocks.

Step 3. Fit 4-module blocks together by interlocking them.

Step 4. Add the linking pins and safety clips.

Step 5. Wire the 4-module blocks together using the connector PCB if a series connection is required. Screw the PCB to the inside of a rear cover.

Step 6. Fit the HAM03191 flying bracket to the top O-Line module of the array.

Step 7. Fit one of the HAM03192 tie brackets to the second module from the top to form a safety point.

Step 8. Fit the second HAM03192 tie-bracket to the module indicated by the software. The bracket position and orientation depend on the angle setting. Attach the bracket, temporarily removing linking pins if necessary.

Step 9. Refit the rear covers using the cut-away covers around the tie brackets.

Step 10. Employ a professional rigger to rig the system from the HAM03191 flying bracket at the front and the lower HAM03192 tie brackets at the rear.

Step 11. Add an extra safety wire rope between the top tie-bracket and an approved, secure part of the building structure.

Step 12. Recheck everything. If you are inexperienced, get an independent safety check.

Step 13. ALWAYS double-check that all orange safety clips are in place to ensure the array remains safely locked.

The bottom cover provides a neat finish and is useful for flown arrays where the bottom is visible. It uses the same nuts and bolts as the linking plates.

Step 1. Ensure the back cover of the lowest O-Line module is removed.

Step 2. For easier access, remove the rear covers and orange safety clips from the bottom two modules.

Step 3. Position the bottom cover in place under the lowest module. The mounting bracket on the cover will fit snugly between the O-Line steel brackets, and the holes will align with the linking plate holes.

Step 4. Fit the spare linking plate nuts and bolts, starting with the lowest two.

Step 5. Tighten the fixing nuts and bolts with a 4mm Allen Key and a 10mm open-ended spanner.

Step 6. REPLACE ANY SAFETY CLIPS THAT YOU REMOVED. Then replace the back covers of the modules.

Step 7. Recheck everything before flying the array.

Your MARTIN AUDIO O-LINE is delivered in blocks of 4 modules ready-wired in parallel. These blocks can be separated, linked, and paralleled to other blocks, or series-connected using the supplied series connector PCB. The series connector PCB also provides an input termination.

When connecting, note that white is negative and red is 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.

To obtain optimal performance, use the following amplifier choices and limiter settings. 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. A standard 60Hz high pass filter is also recommended.

Clip Limiter Settings: AES ratings allow for up to 6dB voltage (4 x power) instantaneous peaks. Therefore, set your DX1.5 or DX2 output channel Clip Limiters to +6dB.

Amplifier and Long-Term Limiter Settings:

Single O-Line modules are 16-ohm elements. Four modules are supplied connected in parallel to form a 4-ohm block. You can reconfigure them for different impedances.

The Advanced Optimised System for the MARTIN AUDIO O-LINE uses the Display 2.3 software application to enhance performance. It calculates both inter-module angles and DSP parameters using sophisticated processing with FIR filters. The software generates a single file (d2p file) with processing coefficients that can be uploaded to an iKON amplifier via Vu-Net software.

A choice of resolution is available:

• 8-box resolution: Every block of 8 cabinets is powered by an individual amplifier channel.

• 4-box resolution: Every block of 4 cabinets is powered by an individual amplifier channel.

• Single box resolution: Every O-Line module uses an individual amplifier channel for the highest level of control.

Vu-Net is used to upload the O-Line optimisation presets created in Display 2.3 into the iKON amplifiers.

Step 1. Connect your iKON amplifiers to a standard Ethernet network.

Step 2. Open Vu-Net. The application opens with a blank System diagram.

Step 3. Use the ‘Discover Devices’ button. The application will search the network for all Vu-Net enabled devices and run an installation wizard to add them to the project.

Step 4. Right-click on the amplifiers to access the Preset Manager.

Step 5. From the Preset Manager, select the appropriate Preset to drive your O-Line array (e.g., ‘O-Line’).

Step 6. Navigate to and select the d2p file created using Display 2.3. Select the Preset from the file and the first channel of the amplifier where you wish to upload the file.

Step 7. Click ‘Load’. The file is uploaded, and an icon of your array is added to the project. For a stereo system, repeat the process for the second array on the next amplifier channel(s).

Step 8. Return to the project system diagram and double-click on the amplifiers to edit settings like delay, EQ, routing, etc., to suit your application.

MARTIN AUDIO O-LINE is supplied in blocks of four modules linked in parallel. To use other configurations, you will need to modify the connections. O-Line connections are made using red (positive) and white (negative) cable to the Phoenix connectors on each module.

Step 1. To access the Phoenix connector, which is in a recess under the rigging bracket, it is best removed with a pair of long-nose pliers. There is enough slack on the connecting wires to pull the connector clear.

Step 2. Use a 2mm flat head screwdriver to access the screws in the top of the connector to loosen and remove any of the wires.

Step 3. To completely remove a link, disconnect both ends of both the red and white wires. The wires run under the rigging bracket but can be pulled clear, again using long-nose pliers.

Step 4. Add new connections direct from an amplifier channel as required by your new wiring configuration.

Step 5. Once you have re-configured the wiring, don’t forget to firmly push home all Phoenix connectors.
