Be sure to always visually inspect all accessories and loudspeakers before use. In fixed installations, regularly check all system components for signs of wear. Visual inspection includes checking the system components of the speakers as well as the mounting components. During the inspection, check all mounting components carefully for deformations, cracks, bolt damage, and corrosion. If there are signs of wear, cracks,
or deformation, etc., replace the affected parts immediately. See also the “Care and Maintenance” chapter.

Safety Instructions When Mounting the System to a Truss

Improperly mounted speakers are not safe for suspending. Objects falling down impose a deadly risk for people standing near-by! Don’t use the mounting system, if you have any doubts regarding its safety and reliability!
Warning
Only qualified event technicians are permitted to suspend a VIDA L system.
When suspending VIDA L speakers, be sure to use the mounting components described in these user’s manual.
Ensure that all connections are secured against coming loose and that only authorized, statically tested and correctly sized supports, mounting equipment, wire ropes and chains are used. Follow the relevant specified safety factors. Be sure to follow the relevant national specifications, norms, and safety regulations.
Note that every suspension point as well as the supporting structure of the building (i.e. ceiling points, cross beams and stage or PA tower, etc.) must be capable of carrying the total load of the system (including cabling and additional fittings).
Note that the suspension points on the hall ceiling (i.e. shackles, attachment points, or chain hoists) must comply with the DGUV regulations 17 and 18 or similar locally applicable accident-control standards. The maximum load must have been certified by an authorized expert. When in doubt, request a confirmation by local authorities.
Also follow the operating and safety instructions supplied with the product you intend to suspend the speaker system from. Never mount the speaker system to a product if there is no information on safe use and maximum load.
Ensure there is sufficient clear space for assembling and suspending the speakers on-site.
Remember that the truss holding the speaker may swing out wide!
Permit only personnel directly involved with assembly or disassembly to access the working area. The person in charge must announce all system lifting and lowering activities beforehand and make sure everybody is aware of that. In this case, all persons present must leave the swing and lifting range immediately.
Never use suspended speakers as a climbing aid.

Installation

Danger! Risk of injury from falling objects!
Improperly mounted speakers are not safe for suspending. Objects falling down impose a deadly risk for people standing near-by!
Always use the supplied M8 x 50 bolts only for mounting the bracket/handhold. Tighten all screws and bolts to the correct torque (16 Nm).
Warning
Only the supplied slot nuts must be used at the rear rail.
Setting up the speaker system requires two persons or a suitable lift for carrying and handling.

Required Tools

Use the following tools for mounting the VIDA L mounting bracket/handhold:

• Allen screwdriver (6 mm)
• Torque wrench for 16Nm

Mounting the Bracket/Handhold to a VIDA L Speaker

To improve speaker handling, you might want to mount mounting brackets/handholds to both the upper and the lower parts of the box rear panel.

1. Each factory-preinstalled fastener has a specific function.
   You may mount the mounting bracket/handhold either to the two groove nuts at position (a) or the two groove nuts at position (c). Note that you can use the nuts at position (c) only if no VIDA C has been mounted to position (b).
   The second bracket/handhold needs to be mounted at the opposite end of the speaker box. Consequently, the nut positions at the opposite end are in reverse order.

2. To prevent falling of the speaker box, make sure that all brackets/handholds are mounted using the bolts with relieve shank that are supplied with the unit.
   Attach the mounting bracket/handhold to the M8-thread slot nuts using the two outer bolts, then screw the bolts in by a few turns.

3. Move the bracket/handhold into position.

4. Now, tighten the bolts.
   Torque: 16Nm
   Check carefully whether all brackets/handholds have been mounted properly: The bolts with relieve shank need to be tightened firmly with no play.

Mounting the Pipe Clips to a Truss or Pipe

Danger! Risk of injury from falling objects!
Improperly mounted speakers are not safe for suspending. Objects falling down impose a deadly risk for people standing near-by!
Please be sure to mount to a K&F VIDA L Slimline half coupler (K&F item

36137) only!

Warning
Attach the pipe clip to the VIDA L mounting bracket/handhold only using the supplied pipe-clip screw. Only screws of that type are specifically made and tested for mounting a pipe clip to a VIDA L bracket/handhold.
Tighten all bolts and screws to a torque of 16 Nm.
Use only the supplied pipe-clip screws for mounting the pipe clips to the mounting brackets/handholds.
When mounting the speaker system combined with a VIDA C laterally to a truss or pipe, attach the pipe clips to one side of the mounting bracket/handhold.

Mounting to a Truss or Pipe

Be sure to use the K&F VIDA L Slimline half coupler (K&F item #36137) for mounting the speaker systems to trusses or pipes!
The pipe clips specified by KLING & FREITAG are designed for customary pipe surfaces and diameters of 48 to 51 mm.
The interconnect points on the truss elements or pipes must be clean, dry, and free of oil and grease.
Warning
Make sure all mounting brackets/handholds and pipe clips are securely attached. Note that even pipe clips that have been properly tightened may still move under load if the truss or pipe features specific surface finishes or coatings. In this case, ensure an appropriate degree of friction between the truss or pipe and the pipe clip.
Improper mounting of mounting brackets/handholds can result in the speaker falling down and imposes risks of personal injury or damage.
Also be sure to place speakers vertically in case of lateral pipe-clip mounting.
Please take note of the numbers of pipe clips indicated in the below examples. To prevent mistakes leading to safety risks, be sure to double-check the number of pipe clips to use according to your calculations.
When suspending VIDA L speakers using mounting brackets/handholds and pipe clips, note that you may form arrays made up of 3 speakers at the most!
Horizontal arrays must be made up of no more than 8 speakers.
A horizontal array is any configuration of suspended speakers with the grill facing downwards.
If you want to mount VIDA L speakers to trusses, perform preassembly and attach the speakers to trusses or rig poles on the ground as possible. Where this is not feasible, perform all preparatory steps on the ground, then pull up the speaker(s) to mount them to the truss.

Example 1:
Each side of a speaker array or a single speaker as well as each interconnect point of two speakers must be connected to the truss or a dedicated rig pole using one pipe clip.
General Rule:
With vertical suspension as well as horizontal suspension without VIDA C, reckon at least one pipe clip more than the total number of speakers to suspend.

• 1 speakers: 2 pipe clips
• 2 speakers: 3 pipe clips
• 3 speakers: 4 pipe clips etc.

The figure shows 2 speakers suspended using 3 pipe clips.
Exception: With speakers fitted with VIDA C that you intend to suspend horizontally, you need to double the number of pipe clips. (See example 4.)

Example 2:
When VIDA L speakers are used in combination with VIDA C, note that you can attach the pipe clips laterally only.
This single-sided attachment of pipe clips necessitates vertical speaker placement.Mounting a VIDA L speaker featuring the VIDA C using a single-sided pipe-clip configuration is prohibited! Example 3:
When suspending a VIDA L speaker without the VIDA C horizontally from a truss, center the pipe clips on the mounting bracket/handhold.
As an alternative, you may mount twice the number of pipe clips to the ends of the mounting brackets/handhold and suspend the speaker or array on both sides from suitable truss elements or pipes of appropriate thickness. (Also see example 4 without VIDA C.) Example 4:
If you want to suspend VIDA L speakers with VIDA C horizontally as an array, be sure to mount pipe clips to both ends of the speaker and fix these appropriately to trusses or rig pipes.
This means you need to use twice the number of pipe clips compared to vertical placement.

Mounting to a Truss

The following is required for performing the steps described in this section:

• Allen wrench (6 mm)
• Torque wrench (16 to 30 Nm)

1. Perform all steps separately and in succession using an installation lift. Start with the top speaker, then build the array top-down.
   Alternatively, you can mount an entire speaker array using a motorized chain host.
   When doing so, note that you need to mount a VIDA L flying frame to the topmost speaker to ensure safe lifting. VIDA L
   Use chain hoists to configure an array of multiple interconnected speakers. Unload the array only after mounting all pipe clips!

2. If you want to raise and lift the speaker manually, you might want to use a flying bracket for lifting.
   Lift the speaker to the desired height, then align it to the truss.

3. Where struts are obstructive, move the mounting brackets/handholds as necessary to vary the pipe-clip positions.
   Tighten the bolts to a 16 Nm torque.

4. Attach the pipe clips to the truss one by one.
   Tighten the M12 nut to a 30 Nm torque (max.).

5. Secure the M12 nut by handtighten the butterfly nut against the nut.
   Check all pipe clips carefully for secure fit.
   Unload the speaker or array only after fixing all pipe clips and checking for secure fit.

Mounting on the Ground

1. Note that the number of required pipe clips is always one more than the number of speakers included in the array. (See also example 1.)If you want to mount multiple speakers on top of each other to a truss, you may want to interconnect them with each other on the ground.
   Interconnect the speakers as described in the VIDA L Speaker user’s manual.

2. Note that moving the mounting brackets/handholds might be necessary in order to freely position the speakers to the truss. For that purpose, align the mounting-bracket/handhold position on the speaker with the truss struts.

3. Move the pipe clips on the mounting brackets/handholds as necessary.
   Attach the pipe clips to the truss one by one.
   Tighten the M12 nut to a 30 Nm torque (max.).

4. Secure the M12 nut by hand- tighten the butterfly nut against the nut.
   Check all pipe clips carefully for secure fit.

5. Danger! Risk of injury from falling objects!
   Improperly mounted speakers are not safe for suspending. Objects falling down impose a deadly risk for people standing near-by!
   Warning
   When the final pipe clip has been mounted, double-check all interconnect points of the entire speaker configuration for secure fit.
   Carefully raise the truss with the speakers mounted using an appropriate lift, then integrate it into your statically tested truss structure.

Speaker installation is now complete, so you can start the cabling.

Dismounting

Warning
Dismounting the speaker system requires two persons or a suitable lift for carrying and handling.
Tip
Basically, dismounting the speakers is performed in reverse order of the installation process.
When dismounting is completed, store all speakers and accessories in the transportation case. This way, they cannot get lost and are always at hand when needed. In addition, the parts are protected at least temporarily against the effects of unfavorable weather conditions, etc.

Warning

1. Secure the speaker or array using a VIDA L flying frame, a VIDA L flying bracket, or an appropriate lift before releasing the pipe clips.
2. Open the pipe clips carefully.
3. Separate the speaker or array from the truss.
4. Dismount the array as described in the speaker user’s manual.
5. Place all speakers into transportation cases.
6. Mounting brackets/handholds can be stored together with the VIDA L in the transportation case. This ensures the accessories cannot get lost.

Dimensions and Weight

• Handhold weight (incl. bolts): 0.5 kg
• Pipe-clip weight: 0.25 kg

Transportation and Storage

Always protect all metal parts from even temporary moisture. Store, transport, and use the accessories in dry environments only. Speaker accessories are not designed for prolonged use in corrosive environments.
Make sure that the system is adequately ventilated during longer storage periods so any residual moisture can escape from the equipment.
In addition, protect all system parts and VIDA L accessories from mechanical strains in order to prevent damage.

Care and Maintenance

For the owner and user, it is mandatory to be aware that speaker accessories used to fly or mount the speakers are fundamentally safety-relevant.
Over time, the accessories may exhibit signs of wear, for example, from mechanical strain, transport damage, corrosion, or improper handling.
As a basic principle, you must visually inspect the speaker accessory before and after you use it. For fixed installations, you must inspect it for signs of wear at regular intervals.
Warning
When performing those checks, particularly look for deformations, cracks, dents, damage to threads, and corrosion. Also check slings and lifts (e.g. shackles, chains, and steel ropes) carefully for wear and deformation.
If as a result of these checks any uncertainty should arise with regard to safety or if specific faults are found, stop using the accessories and send in the product to KLING & FREITAG GMBH for inspection and repairs, if necessary.
Inspection regulations may vary depending on application and country of use. Observe all applicable regulations; when in doubt, contact the local authorities.
Many countries require regular inspection of mounting components and accessories. An additional annual inspection is typically required to be performed by a technical expert. Moreover, a legally certified or official authority must perform a detailed inspection every four years.
Therefore, be sure to maintain an inspection log. Enter the values determined for each speaker and accessory during the periodic checks into this log. This way, relevant data are always at hand in case of inspection. The log should also document maintenance measures and inspection intervals and contain parts lists.
