About this Quick Start Guide
This QSG describes details of the KT10 HP, KT12-HP, and KT15-HP loudspeakers and shows various options such as mounting on a pole or tripod, suspending weyebolts, and mounting in portrait or landscape orientation.
The instructions do not show details of external lifting equipment and do not contain details of safe lifting procedures or installation.
Possession of these instructions and procedures does not imply authorisation for their use.

General Safety
The operation of your product as part of a suspended system, if installed incorrectly and improperly, can potentially expose persons to serious health risks and even death. In addition, please ensure that electrical, mechanical and acoustic considerations are discussed with qualified and certified (by local, state or national authorities) personnel prior to any installation or flying.
Installation and setup should only be carried out by qualified and authorised personnel observing the valid local, state and other safety regulations applicable in your country. If any parts or components are missing please contact your dealer before attempting to set up the system.
It is the responsibility of the person installing the assembly to ensure that the suspension/fixing points are suitable for the intended use.
We also recommend you schedule Turbosound training with our sales partners and applications team.
Equipment used to connect to the Turbosound rigging system must be properly rated and must conform to the local, state and other safety regulations. Do not use Turbosound rigging with other types or brands of loudspeakers. This practice may compromise safety standards and Music Tribe Global Brands Ltd will not be responsible for damage or injury so caused.
Welding, or any other means of permanently fixing rigging components to each other or to cabinet fixing points is not allowed. Rigging components or assemblies must only be fixed to Turbosound loudspeaker cabinets using the cabinet fixing points.
Music Tribe Global Brands Ltd assumes no liability for any damage or personal injury resulting from improper use, installation or operation of the product. Regular checks must be conducted by qualified personnel to ensure that the system remains in a secure and stable condition. Make sure that, where the product is suspended, the area underneath the product is free of human traffic. Do not suspend the product in areas which can be entered or used by members of the public. Speakers create magnetic field, even if not in operation. Therefore, please keep all materials that can be affected by such fields (discs, computers, monitors, etc) at a safe distance, usually between 1 and 2 metres away.

Secondary Safeties
All loudspeakers flown in theatres, studios or other places of work and entertainment shall, in addition to the principle load bearing means of suspension, be provided with an independent, properly rated, and securely attached secondary safety. Only steel wire ropes or steel chains of an approved construction and load rating shall be used as secondary safeties. Plastic-covered steel wire ropes are not permitted for use as secondary safeties.
The secondary safety suspension must be independent of the primary suspension points and capable of carrying the total system weight. The additional safety device must be mounted in a way that the loudspeaker is caught by the safety device without any drop and swing, in the event that the primary suspension fails.
Operational Safety
The procedures require the use of two or more authorised persons.
Produce a lift plan: before any lift takes place, you must formulate a lift plan that describes the exact steps and procedures that will be carried out.
The plan must be shared with all assistants and stake-holders in the lift so that each person will understand their responsibilities.
Observe all instructions given on the respective instruction labels of the rigging components and loudspeakers.
When using chain hoists, make sure nobody is directly underneath or in the vicinity of the loudspeakers.
During assembly pay attention to the possible risk of crushing.
Wear suitable protective clothing.
Safety Inspections
Carefully inspect rigging system components and cabinets for defects or signs of damage before proceeding to assemble the speaker to be flown. If any parts are damaged or suspect, or if there is any doubt as to the proper functioning and safety of the items DO NOT USE THEM and withdraw them from use immediately.
System Requirements
The KT Series of 2-way loudspeaker operates as a passive system and requires only one amplifier channel. The input signal is divided between the low- frequency and high frequency drivers internally with a passive crossover.
Amplifier Considerations
The KT series loudspeakers are optimized for use with the Lab Gruppen PD & PDX series amplifiers The use of third party amplification and processing is only advised using professional loudspeaker limiter calculator The KT series enclosures should be driven by high quality power amplifiers designed for true professional use. Power amplifiers should be capable of delivering long term broadband power, equal to half the loudspeaker’s peak power rating at its stated nominal impedance. The use of underpowered amplifiers must be avoided as heavily clipped signals can cause permanent loudspeaker damage.

Limiters, crossovers and equalisation points must be set in accordance with the settings provided on the Turbosound website. This will ensure the optimum sound quality and long-term reliability as well as protection from damage.
System Cabling Requirements
To avoid wasting amplifier power, you should use heavy-duty speaker cable with a minimum wire size of 2.5 mm² (14 AWG), and preferably 4 mm² (12 AWG) for longer runs or where total cabinet input impedance is less than 8 ohms. For extreme cable lengths, be aware of cable impedance and resistive losses.
Always observe the correct polarity.
Use genuine NEUTRIK SPEAKON CONNECTORS for reliable operation.
Attach and support the speaker cables from your amplifiers to the loudspeaker cabinets, so that no significant additional weight or lateral force is applied to the speakers by the input wiring. Input cables or link cables should never be used to angle the speakers or used as rigging in any way.

Stereo System Example

The example below shows a Lab.gruppen PD3000 Amplifier used in Stereo mode and full frequency range, with two KT12-HP speakers. Both speaker cables are wired Pin 1 +/-.

Connections

Caution: The speaker inpedance is 8 Ohms. Do not Link more than 2 speakers per channel, unless your amplifier can handle loads less than 4 Ohms.

Installation

Safety Warning: Only authorised and certified personnel shall design and install suspended configurations. Incorrect installation may lead to death or permanent injury Walls, floors or ceilings must be capable of safely and securely supporting the actual load. The mounting accessory used must be safely and securely fixed both to the loudspeaker and to the wall, floor or ceiling.
When mounting rigging components on walls, floors or ceilings, ensure that all fixings and fasteners used are of an appropriate size and load rating.
Wall and ceiling claddings, and the construction and composition of walls and ceilings, all need to be taken into account when determining whether a particular fixing arrangement can be safely employed for a particular load. Cavity plugs or other specialist fixings, if required, must be of an appropriate type, and must be fitted and used in accordance with the maker’s instructions.
The use of a secondary safety is a mandatory safety requirement.
The KT speaker cabinet has an integral pole mount hole and M10 mounting holes with fitted hex socket head screws.
Caution: As the KT series loudspeakers are rear ported, it is important to leave a gap of 50 mm or more, to allow low frequency energy to exit the rear ports.

Suspending with Eyebolts
KT Series cabinets can be suspended using optional eyebolts coupled to the internal rigging points provided on the top, bottom and sides and back.
The simplest method is to use the two rigging points on the top and a single pull-back rigging point in the centre of the rear panel. Use another eyebolt on top for the secondary safety cable.
Remove the appropriate countersunk screws and replace them with shoulder eyebolts, which must have a thread length of at least 40 mm. Use the rear rigging point to angle the cabinet for optimum room coverage. Cabinets may be hung upside down if required.

Pole Mount
One 35 mm pole mount socket is provided for pole mounting in the vertical position. The speaker can be pole mounted on a suitable tripod stand.

Badge Rotation
The Turbosound badge can be rotated by hand to suit vertical or horizontal positioning.

Horn Rotation
The MF/HF Horn assembly can be removed and reinstalled in a different orientation to suit desired configurations and coverage.
For example, if the speaker is used in landscape mode, then rotate the horn by 90 degrees to maintain the same horizontal and vertical beamwidths/coverage as in the portrait mode. Follow the procedure below to rotate the horn:
Remove the grille by undoing the six crosshead screws on each side. Remove the 8 M5 hexagonal socket screws securing the horn assembly to the cabinet. Carefully pull the horn assembly forward, just enough to be able to rotate the assembly to the desired orientation.
Reinstall the horn with the 8 screws. Make sure the wiring is intact and not pinched. Reinstall the grille, and make a note that the speaker has been modified.
