About this Quick Start Guide
This QSG describes details of the TQ15B and TQ18B subwoofers. These instructions shall only be used with these components.
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.
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. Do not modify the accessories, or use them in a way other than that described in this QSG. Rigging  components supplied as part of a complete assembly are non- interchangeable and must not be exchanged with the component parts of any other assembly.
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.
Always refer to EASE Focus 3 modeling software error and warning indications prior to installation.

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 stakeholders 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
TQ15B and TQ18B subwoofers operate as a passive system and require only one amplifier channel and DSP for normal forward firing operation; Cardioid bass set ups will require additional amplifier and DSP channels.
All TQ series loudspeakers exclusively use Lake pre-sets via Lab Gruppen PLM+ and D series L platforms, Lab Gruppen IPX Series pre-sets will be released in due time.
No 3rd-party amplifier and DSP platforms are supported, no raw pre-set data is released or supported.
The TQ15B and TQ18B subwoofers have a powerful yet simple pre-set strategy utilizing the latest functionality of LAKE XP software.
Pre-set data is found either via Lake LOAD Library (https://www.labgruppen.com/downloads.html) or can be downloaded from https://www.turbosound.com/downloads.html
Recommended Lab Gruppen PLM+ models for Touring applications are the PLM8k44, PLM12k44 and PLM20k44.
For installations using Lab Gruppen D series L models, please use Lab Gruppen ‘CAFE’ software – available for download from www.labgruppen.com -to determine the optimum amplifier configuration for your system.

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.

Subwoofer Cabling
NOTE: Since the TQ15B/TQ18B subwoofer is wired 1+/- = LF and 2+/- = LINK, in order to power multiple enclosures, it is advised to construct SUB LINK cables wired: 2+ -> 1+ and 2- -> 1- .
To power two subwoofers per amplifier channel, standard NL4 link cables from Lab Gruppen bi-wired NL4 outputs (Channel 1 = 1+/-; Channel 2 = 2+/-) can be used in conjunction with a SUB LINK cable. Refer to wiring diagrams below for further details.
To power one subwoofer per amplifier channel, a single NL4 cable from Lab Gruppen bi-wired NL4 outputs (Channel 1 = 1+/-; Channel 2 = 2+/-) connects to the first subwoofer, then the SUB LINK cable connects to the second subwoofer.

Connections

Caution : It is mandatory to use the official factory Lake pre-set. Failure to do so will result in component failure of the TQ passive crossover and transducers. No other 3rd party DSP or Amplifiers are supported

Rigging and Acoustic Simulation Software

The TQ15B/TQ18B is not an arrayable product. It is supported in Ease Focus 3, an acoustic simulation program, available as a free download from https://www.afmg.eu/en/ease-focus

Full EASE data can be downloaded from www.turbosound.com
This will allow acoustic prediction, array formation and suspension to be determined. Important safety information about WLL is also calculated by EASE Focus.

Installation

Safety Warning: Only authorised and certified personnel shall design and install suspended configurations. Incorrect installation may lead to death or permanent injury.
The use of a secondary safety is a mandatory safety requirement if installing this product with the M10 rigging points.
The TQ15B/TQ18B has feet on the bottom for standing the speaker on a flat surface, two integral pole mount holes, and M10 mounting holes with fitted hex socket head screws. Ground stacking
The TQ15B/TQ18B can be ground stacked in the horizontal or vertical orientation.
In the vertical orientation, try mounting two of them with the ports next to each other, as shown.
Suitable racket straps looped around the group of cabinets is advised as an additional safety measure. Badge Rotation
The Turbosound badge is spring-loaded and can be rotated by hand to suit vertical or horizontal positioning.

Suspension
The TQ15B/TQ18B cabinets can be simply suspended using optional M10 shoulder eyebolts coupled to the internal rigging points provided. Remove the appropriate countersunk screws and replace them with eyebolts, which must have a thread length of at least 40 mm. Cabinets may be hung upside down if required.

Pole Mount
Two 35 mm holes are provided for pole mounting.
We recommend using a 35 mm pole with an M20 thread at the lower end. This type provides more security and will screw into the top receptacle of the TQ15B/TQ18B.

Transport Wheels (option)
An optional kit allows four wheels to be mounted as shown.

Lake Preset Overlays and Application Notes

All TQ series loudspeakers exclusively use Lake XP pre-sets via Lab Gruppen PLM+ and D series L platforms and the forthcoming IPX FiR-X pre-sets.
No other amplifier and DSP platforms are supported.
The TQ series has a powerful yet simple pre-set strategy utilizing the latest functionality of Lake software, along with new BLEQ overlays.
Pre-set data is found either via the Lake Load Library, or can be downloaded from www.turbosound.com
TQ15B and TQ18B subwoofers each have individual 1 way passive FIR base pre- sets (1 channel DSP/AMP).
CAUTION: Do not combine TQ15B and TQ18B subwoofers on the same amplifier / DSP circuit. Failure to follow these instructions may lead to damage to the equipment.
CAUTION: Pay careful attention to output patching.
TQ15B and TQ18B modules are based on the XP module from Lake software.
This QSG refers to REV1.1 XP presets.
Lake software V7.0.7 or above must be used.
Lake XP signal flow:

The download of the Lake controller includes the Lake Controller Operation Manual, which is a full tutorial of the Lake Controller and compatible hardware such as PLM+ series amplifiers Within this QSG, we focus on the Turbosound TQ series workflow and pre-set strategy, and assume basic working knowledge of the Lake Controller.

The TQ15B/TQ18B subwoofers have a powerful yet simple Subwoofer pre-set strategy.
Caution: Do not combine TQ15B and TQ18B subwoofers
on the same amplifier/DSP circuit.|

SUBWOOFER TIME ALIGNMENT| ILLUSTRATION| OVERLAY
---|---|---
The TQ15B/TQ18B subwoofer pre-sets use all-pass filters to set the initial time alignment (assuming the fronts of the cabinets are in line)this greatly reduces system latency.
For example: If the fronts of the TQ speaker and subwoofer are aligned, then in both pre-sets, the delay should be set to the default, which is 0ms.
However, it is not always possible to have the flown speakers and the ground stacked bass aligned in the vertical plane.
1. In this example, the sub is ‘forward’ of the TQ
speaker, and so the sub needs to be delayed.| 1.  Sub forward| Delay adjustment of subwoofers
2.  In this example, the flown TQ speaker is ‘forward’ of the subs, and so the TQ needs to be delayed.
How do you find the correct delay time to align the flown speakers to the ground stacked bass?
Some basic knowledge of delay units can get you an acceptable result by measuring the distance between the fronts of the flown speaker and the front of the ground stacked array. Remember within Lake software you can choose the delay unit; ms, m, or feet.
1 ms (milliseconds) = 0.343 m (meters) = 1.125
ft (feet)
Further fine-tuning can be done by using one of the many industry standard measurement software systems, reference microphones and sound-cards. Lake software offers integration to many of these software systems, and further information can be found at www.labgruppen.com| 2. Flown TQ is forward| Delay adjustment of TQ speaker
