Flex Array Concepts

The Flex Array system is a modular flexible array loudspeaker system designed to deliver
extremely high fidelity audio in a range of medium scale fixed and portable sound
reinforcement applications.

Flex Array combines elements of line array theory and virtual point source theory in one
loudspeaker product, and for the first time offers virtually unlimited flexibility in adapting to a
huge variety of venue types and audience areas.

The Polyhorn™ Concept

The patented Polyhorn™ effectively solves several of the problems associated with
conventional exponential horns: namely the tendency to „beam‟ with increasing frequency;

and the undesirable comb filtering effects generated between adjacent devices due to the

variable curvature of the wavefront caused by the horn‟s geometry.

The Polyhorn™ is split into multiple cells, or individual „hornlets‟, which connect the

diaphragm to the horn mouth. Dividing the multi-cellular horn into multiple tapered
waveguides guarantees that the path length of each micro-horn is equal from the surface of
the driver diaphragm to the horn mouth, and ensures that all frequencies from all parts of the
diaphragm arrive at the horn mouth together. This provides the wavefront with uniformity of
phase.

The Polyhorn™ geometry ensures that the sound wave does not suffer from edge-diffraction
effects which have a tendency to confuse the directionality of the sound source.

Each cabinet in an array containing Polyhorn™ devices contributes to the generation of a
single, cohesive, and more or less continuous wavefront without noticeable comb-filtering
effects. In addition, the Polyhorn design offers the possibility of locating the acoustic centre
well behind the motor system and even the enclosure.

The Polyhorn™ devices exhibit a sharp cut-off at the edges of the dispersion pattern, making
it possible to achieve seamless coverage of a venue with minimal destructive interference
between elements, irrespective of how many individual enclosures are deployed in the
cluster. Because of the Polyhorn™ design‟s sharp cut-off, its array angle can in practice be
taken as being the same as the dispersion angle.

The Polyhorn™ design allows the extension of an application central to Turbosound‟s

philosophy – the use of cone drivers to cover mid-range (especially vocal) frequencies and
the freedom to apply relatively high crossover frequencies in order to minimise the distortion
common to metal-diaphragm compression drivers. The Polyhorn™ is employed in the high-
mid section of the Flex Array TFA-600H, loading a custom-designed 6.5” high power
neodymium drive unit.

The Dendritic Horn

The patent-pending Dendritic HF horn utilises the same essential acoustic principle as is
employed in the Polyhorn: namely the application of equal path length hornlets to generate a
phase-coherent wavefront at the horn mouth. An extension of the principle allows the

Dendritic horn to act as the waveguide for a 1” throat compression driver, and key to the

operation of this new approach is the divide-by-two rule. Each section of the Dendritic
waveguide is split exactly two ways, ensuring that the signal in each leg is identical. In this
manner the output from a single compression driver is spread evenly across sixteen small
outputs.

Although adaptable to a range of output configurations, the Dendritic horn lends itself most
naturally to a slot output. By virtue of its tightly contorted pathways, the Dendritic creates a
very compact device, typically cutting 40% off the length of the external envelope.

The Flex Array Mid/High Waveguide

The Flex Array TFA-600 combines both Polyhorn and Dendritic horn technologies in a single,
physically aligned mid/high waveguide with equal path lengths, which produces a phase­coherent wavefront at the horn mouth. The Dendritic horn‟s compact dimensions allows the
high frequency driver to be located directly in front of, and mounted concentrically with, the
high-mid frequency driver. The horn‟s shallow geometry, comprising the combined horn and
the concentric mounting of the mid frequency and high frequency drivers, results in a very

compact enclosure with a depth of only 560mm (22”). This is beneficial both for keeping

cluster footprint small and is also a convenient dimension for trucking.

The combined waveguide is square in section, allowing it to be rapidly and easily removed
and rotated within the enclosure to suit the intended application. In this way the 75°
horizontal by 16° vertical coverage pattern can be readily transposed relative to the
orientation of the cabinet.

The Loudspeaker Management System (LMS) Concept

Turbosound Loudspeaker Management Systems are more than just electronic crossovers. As
well as steep slope active filters and high performance limiters, they provide full digital
alignment of all components in the loudspeaker enclosures, to ensure coherent acoustic
output. They also incorporates a number of features which contribute to overall system
reliability and ease of setting-up and use.

All system parameters such as crossover frequencies, limiter settings, and equalisation can
be simply called up from a factory-preset menu, making it possible to maintain consistent
and repeatable system performance.

Because the power amplifiers can be included as part of the audio system, the controllers
utilise output limiters which are matched to the system requirements, being preset to prevent
the amplifiers from clipping under normal operating conditions. Inputs and outputs are fully
balanced, providing isolation between the controller and the amplifier inputs. These factors
contribute to high reliability in the adverse circumstances often encountered under arduous
touring conditions.

In addition, LMS-D2X series controllers are equipped with built-in network capability,
allowing maximum control and flexibility over the loudspeaker system‟s performance and
security.

LMS-D2x Loudspeaker Management Systems

Use of Turbosound loudspeaker management systems ensures accurate time-alignment of
the system drive units and also provides a facility for users to select additional delay, either
to compensate for physical displacement of ground-stacked bass enclosures relative to flown
high packs, or to provide full range delay for correct image localisation or use in distributed
systems.

Power Amplifiers

In addition to the Turbosound T-series amplifiers recommended for use with Flex Array
systems, the following other power amplifier brands provide sufficient performance and
mechanical compatibility to perform well with Flex Array loudspeaker systems:

 MC2 E series
 Lab Gruppen FP series
 Crest Pro series
 QSC Powerlight II series

Digital Controllers

In addition to the Turbosound LMS-D24 and LMS-D26 loudspeaker management systems, the
following digital crossover has been tested and is recommended for use:

 XTA 4 series controllers

Self-Powered Loudspeakers

Flex Array series cabinets are optionally available with integrated networkable Class D
amplifier modules in a self-powered format, taking consistent performance and ease of use
to a new level. Featuring lightweight high-power amplifiers using 96kHz DSP and operating
at better than 90% efficiency, self-powered Flex Array products eliminate the need for
separate amplifier racks and controllers, as well as the attendant cabling.

Due to their extremely high efficiency and modern, high performance power supplies, the
amplifier module only adds a few kilos to the overall net weight of the loudspeaker.

The sophisticated DSP allows multiple internal preset recall either via the rear panel or over a
remote link.

Self-powered loudspeakers can be conveniently controlled and monitored over a network
with a PC running TurboDrive™ software.

Class D amplifier modules can be retrofitted to non-powered enclosures in place of the
Speakon connector panel, providing a quick and effective upgrade path.

Model Information

TFA-600H Three-Way Loudspeaker

The TFA-600H is a compact, trapezoidal, modular three-way switchable tri-amped/bi-amped
loudspeaker. It combines a patent-pending Dendritic HF waveguide and a patented midrange

Polyhorn™ in a single physically aligned waveguide. This geometry allows the enclosure‟s

dispersion to be easily adapted to line array or virtual point source implementation.

The loudspeaker‟s 75° horizontal dispersion pattern maximises the direct sound field while
reducing reverberant energy. Two Flex Array columns arrayed at 55° provide an ideal 130° of
horizontal coverage for wider auditoriums or outdoor events.

Neodymium drive units are used throughout the product in order to achieve exceptionally
low net weight, making it convenient to transport, handle and rig. In addition the drive units
are symmetrically located within the enclosure, which contributes to the smooth and
consistent horizontal coverage. The upper crossover point is positioned at 6kHz, giving the
legendary Turbosound midrange power and clarity that is only possible from a paper cone
type transducer.

The enclosure has both vertical and horizontal flying systems integrated into the cabinet. The
horizontal system uses a simple and effective drop link mechanism which permits easy
positioning and angling of each cabinet within any given line array configuration. Enclosures
are equipped with captive biscuits for use with chain links in virtual point source clusters, and
with a range of flying yokes for rigging enclosures in point source applications.

The 15mm birch plywood cabinet is equipped with a perforate steel grille with foam backing,
and recessed handles on the sides, rear, top and bottom. A recessed rear panel carries two
parallel-linked Speakon NL8 connectors for input and loop-through connections.

TFA-600HW Wide Dispersion Three-Way Loudspeaker

A wide dispersion version of the standard TFA-600H, but with a wider 100°h x 16°v coverage
pattern. The cabinet is identically sized and features the same integrated flygear - making it
possible to either integrate the TFA-600HW in a cluster of TFA-600H cabinets (for example as
downfills at the bottom of the hang), or to fly these on their own to simply achieve a wider

coverage. This model is quickly identified by the „W‟ legend visible through the window on
each side of the cabinet.

The mid/high section is rotatable to allow a swap of the horizontal and vertical coverage
patterns, and in this configuration the TFA-600HW also works well as a stage lip infill cabinet.

TFA-600HDP Self-Powered Three-Way Loudspeaker

The TFA-600HDP is a networkable, digitally self-powered, bi-amplified, trapezoidal three-way
enclosure combining a patent-pending Dendritic HF waveguide and a patented midrange
Polyhorn™ in a single physically aligned waveguide.

It features a new generation of innovative lightweight Class D amplifiers, utilising
revolutionary 96kHz DSP technology to give operating efficiency in excess of 90%. Two
independent amplifier channels power the LF and MF/HF drivers separately. Neutrik™
Powercon connectors provide mains input and output to permit powering of two further
cabinets, while 3-pin XLRs are used for input and parallel link signal connections. RJ45
network connectors enable multiple loudspeakers to be controlled and monitored over a
BVNet network using TurboDrive™ software.

The enclosure has both vertical and horizontal flying systems integrated into the cabinet in
order to facilitate simple and intuitive rigging with a minimum of external parts. The
horizontal system is used to create flown or ground-stacked line array configurations. The
vertical rigging system is used for single box and virtual point source applications. This
flexibility of use is made possible by the rotatable mid/high section.

TFA-600L Compact Horn-loaded Subwoofer

The TFA-600L is a compact, horn-loaded subwoofer enclosure designed to be flown or
ground stacked with TFA-600H enclosures. It consists of a single 18” neodymium drive unit
loaded with a TurboBass™ device in a birch plywood cabinet. The TFA-600L utilises the same
drive unit as the larger TSW-218 horn-loaded subwoofer and employs the same loading
techniques, so these two bass enclosures can be freely mixed in any application. The

proprietary 18” drive unit is the result of a development project that has produced a unique

neodymium motor system. The magnet system drives a dual-spider, split 4” voice coil which
provides linear BL (magnetic force) with displacement, ensuring optimum control from the

motor assembly and very low harmonic distortion, even at the excursion limits. The 4” voice

coil also results in a lower system moving mass than equivalent 5” units, resulting in higher
sensitivity and exceptional response to fast transient peaks.

The enclosure is equipped with an integrated flying system which enables it to be flown at
the top of a column of Flex Array loudspeakers using a simple conversion frame between the
bass enclosures and mid/highs. The same conversion frame is used to create a stable Flex
Array ground stack. A pole mount socket is provided for use with flying yokes.

The 15mm birch plywood cabinet is equipped with a perforated steel grille with foam backing
and recessed handles on the sides and back, and is supplied with heavy duty wheels in order
to aid trucking and handling.

A recessed panel at the rear of the cabinet carries two parallel-linked Speakon NL4MP
connectors for input and loop-through connections.

TSW-218 Horn-loaded Subwoofer

The TSW-218 is a horn-loaded subwoofer incorporating Turbosound's patented loading
principles, designed for use in applications requiring accurate and powerful reproduction of
low frequency energy at very high levels. Its ability to reproduce program material with such
integrity makes the TSW-218 applicable for both fixed or mobile systems which require
energetic low frequency response without stress or enclosure corrective equalisation.

The TSW-218 incorporates the TurboBass™ device, which employs a high-velocity partial
horn-loading technique, giving precise cone control at high power levels. The proprietary 18”
drive units are the result of a development project that has produced a unique neodymium
motor system. The magnet system drives a dual-spider, split 4” voice coil which provides
linear BL (magnetic force) with displacement, ensuring optimum control from the motor
assembly and very low harmonic distortion even at the excursion limits. The 4” coil also

means a lower system moving mass than equivalent 5” units, resulting in higher sensitivity

and exceptional response to fast transient peaks.

The TSW-218 is capable of outstanding electrical to acoustic power conversion. Optimisation
of the stepped horn flare produces a dramatic increase in sensitivity when multiple units are
coupled.

GigMate™ Acoustic Simulation

While the Flex Array System is remarkably intuitive in terms of building arrays and aiming
them – and requires no theoretical calculations in order to achieve optimum coverage of a
room or audience space – there may well be situations where some prior knowledge of a
venue can save time in setting up and configuring the PA. In order to aid in this process,

Turbosound offers the GigMate™ software acoustic simulation package, a version of the

generic EASE Focus program that is based on current EASE 4.1 data.

GigMate™ provides an accurate elevation representation of sound pressure level and
coverage of a room, given the dimensions of the audience areas and location of available
rigging points in the venue. The database allows for the creation of flown clusters, or for
ground stacked arrays, of TFA-600H mid/high and TFA-600L bass enclosures.

Setting up a Venue - Overview

The Audience Area window provides a way to add or remove Audience Areas and define
their location in the space. A venue can be selected from a range of standard venue presets,
or set up from scratch using the X and Y co-ordinates menus to define the location, size and
angle of the listening areas.

The PA is set up by choosing either a flown cluster or ground stack. Box count, cluster
position, tilt angle and splay angle can all be selected independently.

The mapping properties allow the user to select frequency bands from 125Hz to 8kHz, and
also bandwidth from one-third octave to broadband. Weighting and level can also be
selected here.

Once mapped to achieve satisfactory room coverage and level, results can be saved and
printed as a .rtf file. The program will also calculate the total weight of the cluster as well as
its overall physical size.

Running Turbosound GigMate™ for the first time:

When you first start the program you must set the system file that it is to use. The installation
files include the Flex Array file, as well as the Aspect TA-500 file and two Turbosound Aspect
TA-890 Touring System files as shown below:

Select the Flexv2.efo file . You will now be presented with the GigMate™ main screen:

user manual

FLEX ARRAY

FLEX ARRAY user manual

Page 23

The screen is split into four main areas:

System Setup
The left hand side of the screen is where you define the system, auditorium and project. Tabs
on the bottom of this window allow you to toggle between the three modes.

Mapping Properties
This is the main window which will display the system as configured in the System Setup
window, along with the audience areas and mappings.

Audience Area
Beneath the main Mapping Properties window this graphically displays the SPL on each
audience area, or across a combination of audience areas.

Rigging
The far right window shows the detail of the system configuration, and is especially useful in
larger venues where the speakers shown in the main window become very small.

Designing a System

To design a system begin by defining the venue/audience areas by clicking on the “Audience
Area” tab in the bottom left of the screen.

Within this window you can edit or remove existing audience areas, and create new ones.

user manual

FLEX ARRAY

FLEX ARRAY user manual
Page 24

There are two methods of defining an audience area. In either case you must define the
X1/Y1 coordinate of the start of the area; you can then either enter the X2/Y2 points or its
length and angle.

As you create audience areas they are shown graphically in the main window.

Desiging the Loudspeaker Array

The next step is to design the loudspeaker array using the “System Setup” window. Select
the “System Setup” tab in the bottom left of the screen and begin by choosing the desired

flybar or ground stack in the drop down box at the top left of the window.

Now select the number of cabinets deep that you wish to hang or stack from the “Box Count”
drop-down menu. Trim height or PA wing height can now be set in the “Position” field.

If a mix of Low and High cabinets are to be used then select in the “Cabinet” window the

type and location in the array of each box. The angle between cabinets can now be set in the

“Angle” list. Each cabinet has an aiming line that can be used to determine the centre of each
cabinet‟s dispersion. Adjust the trim height, top angle and inter-cabinet angle to achieve

optimum coverage.

Page 25

Now that the general design has been established the system performance must be mapped.

At the top of the main window there is an “SPL Mapping” checkbox. This will map the

system output at the frequency and bandwidth selected in the adjacent dropdown boxes. For
most applications a one-third octave weighted mapping gives realistic and useful data.

System Mapping Performance

user manual

FLEX ARRAY

FLEX ARRAY user manual
Page 26

The Audience Area graph at the bottom of the window shows the SPL, as specified in the SPL
Mapping lists, on the selected Audience Area. The selected area is highlighted in the main

window and the graph is repeated onto each area. Selecting the “Combined Level View” tab

will show the SPL across all areas simultaneously.

Now that the system is mapped, the inter-cabinet angles or row attenuation may be trimmed
to provide the smoothest coverage. Typically the bottom cabinets of the system will require
some attenuation and should be on their own “Amp way” to achieve this.

Changing the System

GigMate™ currently includes Flex Array TFA-600 systems, as well as Aspect Touring TA-890
series, trapezoidal TA-880 series and TA-500 wide dispersion series products. To switch
between systems use Edit/Change System on the menu bar and select from the list.

Tri-amp / bi-amp configuration

TFA-600H enclosures can be configured either in fully tri-amped mode, or bi-amped with
passive HF. They are shipped from the factory as standard in tri-amped mode, although
changing from one to the other is a simple case of changing the position of a jumper located
behind the connector panel.Please note that the rear flygear must be removed in order to
access the conector panel.

1. Remove the four M6 button-head screws securing the rear panel.

2. The default jumper position as shipped from the factory is TRI-AMP (as shown above
right).

3. For TFA-600HW wide dispersion products relocate the jumper from the TRI-AMP PCB

Transportation

FT-600/3 Transport Case

The FT-600/3 transport case allows a block of three TFA-600H speaker cabinets to be
conveniently transported in a pre-rigged configuration, and is recommended as the most
efficient way to truck and handle the cabinets. The transport case is wide enough to allow the
ball-lock pins to be inserted in the flygear whilst in the case – and therefore makes it possible
to lift the block of three cabinets together – while still being dimensioned to fit three-across in
a standard truck.

Cabinets must be set with 0° inter­cabinet angle while in the case for
transportation, although the desired
cluster angles may be easily set
once the block of cabinets is lifted
out of the case. The use of the FT­600/3 makes for a very quick and
repeatable set up.

Flying and Stacking

Overview

To take full advantage of the extremely flexible properties of the Flex Array system, two
modes of rigging system have been developed and are both fully integrated into the
enclosure. The two rigging systems allow either line arrays or virtual point source clusters to
be assembled – intuitively, quickly and easily, and with an absolute minimum of additional
external parts to suit the coverage requirements of a huge variety of professional sound
reinforcement situations.

The flying systems are inherently safe, flexible, self-contained and simple to use. The load is
taken entirely through the flygear and not through the cabinet‟s woodwork. The rigging
design allows the creation of clusters and arrays that can be assembled quickly and with a
minimum number of crew, and with full control of the vertical angles between enclosures
and the overall cluster inclination.

Safety Notes on Rigging

The Turbosound rigging system has been designed and constructed to a high
standard of safety, and tested to the most demanding of specifications. In order
to ensure the highest safety standards, the information following on the

assembly and safe use of rigging accessories must be carefully understood and followed.

Only use Turbosound recommended rigging accessories, which are specifically designed for
their intended purpose. Do not use Turbosound rigging with other types or brands of
loudspeakers. This practice may compromise safety standards and Turbosound will not be
responsible for damage or injury so caused.

Do not modify the rigging accessories, or use them in any other way than that described in
this user manual. Rigging components supplied as part of a complete assembly are non­interchangeable and must not be exchanged with the component parts of any other
assembly.

The component parts of a Turbosound rigging accessory must only be assembled using the
fasteners and methods of assembly recommended in this manual. The use of fasteners and
methods of assembly not specified or approved by Turbosound may result in an unsafe
rigging assembly. Welding, or any other means of permanently fixing rigging components to
each other or to cabinet fixing points, is not allowed.

user manual

FLEX ARRAY

FLEX ARRAY user manual
Page 32

Rigging assemblies must only be assembled using the appropriate parts and fixings as
specified in this manual using the specific mounting instructions. Rigging components or
assemblies must only be fixed to Turbosound loudspeaker cabinets using the cabinet fixing
points, assembly methods and fasteners specified in this manual and the specific mounting
instructions.

Walls, floors or ceilings must be capable of safely and securely supporting the actual load.
The rigging 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.

Use only the rigging accessory fixing holes indicated in this manual and the specific
mounting instructions to fix Turbosound rigging accessories to walls, floors or ceilings.
Where specified, the recommended maximum torque settings for screw fasteners must be
strictly complied with.

Secondary Safeties

Best practice dictates that all loudspeakers flown in theatres, studios or other places of work
and entertainment should (and where local laws apply), 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 may be
used as secondary safeties. Plastic covered steel wire ropes are not permitted for use as
secondary safeties.

Safety Inspections

Carefully inspect rigging systems components and cabinets for defects or signs
of damage before proceeding to assemble a flown array. If any parts are
damaged or suspect, DO NOT USE THEM.

Regular and more rigorous test and inspection of rigging components must also be carried
out. Safety legislation, and test and inspection requirements, will vary from country to
country. In most cases, annual independent test and inspection by a suitably approved and

user manual

FLEX ARRAY

FLEX ARRAY user manual

Page 33

qualified inspector will be required. Users must ensure compliance with all applicable safety
requirements.

Turbosound recommends regular safety inspections and further recommends that a logbook
be kept detailing the test and inspection history of each Turbosound rigging accessory.

Turbosound has adopted the following load safety factors:

 12 x load safety factor: Chains, ropes, shackles, eyebolts, straps and hooks.

 5 x load safety factor: Accessories generally employed in fixed, permanent

installations.

Always wear protective headwear, footwear, and eye protection in accordance with local
regulations. Anyone involved in flying ANY sound system, especially in a touring capacity,
should take note of the following advice:

The rigging of a flown sound system may be dangerous unless undertaken by qualified
personnel with the required experience and certification to perform the necessary tasks.
Fixing of hanging points in a roof should always be carried out by a professional rigger and
in accordance with the local rules of the venue. The house rigger and/or building manager
must always be consulted.

Flying System components have been individually tested in accordance with

the following UK/EU regulations:

 The Health and Safety at Work Act 1974

 The Supply of Machinery (Safety) Regulations 1992

 The Lifting Operations and Lifting Equipment Regulations 1998

Each component is covered by a Record of Load Test Certificate, which may be obtained on
request from Turbosound, quoting the identifying number(s) from the flying equipment.

Rigging Components

The Flex Array „A‟ mode, or horizontal, rigging system includes all the necessary hardware

to enable vertical suspension of TFA-600 series cabinets from a single rigging point and
using only a single motor rated at 1 tonne.

The FB-600 adjustable lift point flybar supports the entire weight of the loudspeaker cluster
by engaging into the steel flygear rebated into the short sides of the loudspeaker enclosures,
whose integrated drop links locate into the flyware of the cabinet directly underneath to form
the pivot points about which cabinets are angled vertically. The drop links are secured in
position with captive ball-lock pins that stow into cabinet recesses for transportation. The
cabinet‟s rear drop link pivots down to engage in the clevis connection plate of the cabinet
below in several positions, which permits a range of inter-cabinet angle adjustment, in 2°
increments, from 0° to 16°.

FB-600 Adjustable Lift Point Flybar

The FB-600 is a T-shaped flybar that enables the suspension of TFA-600H mid/high and TFA­600L low frequency loudspeakers up to an SWL of 700kg, and is used for the creation of
flown Flex Array line arrays. The frame is constructed from rectangular box steel section with
a unique formed rear spine containing a channel in which the lift point is located.

The movable lift point can be traversed along the length of the spine from front to rear by

means of a screw thread, which is turned by a 22mm (7/8”) socket driven by a speed brace or

hand held electric drill. The screw is located in polymer-sealed bearings requiring no
maintenance under normal operating conditions, and is designed to last the lifetime of the
product.

user manual

FLEX ARRAY

FLEX ARRAY user manual
Page 36

Turning the drive nut on the end of the shaft tilts the load by varying the position of the
motor connection point relative to the centre of mass of the loudspeaker column. The lift
point position can be altered even when under load in order to obtain the desired final cluster
inclination.

The flybar‟s rear spine is provided with multiple locating holes along its length based on a
vernier scale adjustment. A captive 100mm (4”) ball-lock pin is used to lock the lift point‟s

position when one of the two holes in the lift point aligns with a fly bar locating hole.

Floating drop links at each end of the box section engage into the flygear of the TFA-600H
mid/high cabinet or TFA-600L low frequency cabinet, and are secured with captive 15mm
(5/8”) ball-lock pins.

Two cabinet connection drop link positions are provided at the rear of the flybar at the
correct spacing for attachment to either TFA-600L low frequency cabinets or TFA-600H
mid/highs.

The net weight of the FB-600 flybar is 25 kgs.

Important Safety Notes

To ensure continued safe operation of the FB-600 flybar the following points should be noted:

 The BLP-10/100 100mm (4”) locking pin should always be fitted to lock the lift point

before lifting the flybar

 Four ball-lock pins must be fitted to ensure the safe lifting of the cluster

 Under no circumstances should hands be placed in the open top of the spine when the

flybar is in use

 Two safety lug points are provided for attaching wire safety rope. No other part of the

flybar can be used for this purpose

 Any components that are damaged should be repaired or replaced by qualified service

personnel only

 In the extremely unlikely event of failure of the screw the safety and operation of the

flybar is not compromised

Page 37

BLP-600 Ball-lock Pins

These are provided in three sizes depending on application.

 The BLP-8/15 is used to lock cabinets together at the side pivot points and, in

conjunction with the rear links, to set the vertical angles between cabinets

 The BLP-10/35 is used to locate the rear drop links in the cabinet‟s clevis connection

plate

 The BLP-10/100 locks the position of the lift point on the FB-600 flybar

Ball-lock pins are held captive by a lanyard either on the flybar or cabinet, and are normally
parked in a recess in the cabinet side, or on the flybar, when not in use to avoid the
possibility of losing them. They can only be used to engage with the box above, or with an
inter-cabinet coupler.

Rear Drop Link

These are supplied with each mid/high cabinet, and are used to set the inter-cabinet angle by
engaging in the clevis connection plate of the cabinet below. When not in use the rear drop

CF-600 Conversion Frame

Used to interface between bass cabinets and mid/high cabinets in a flown column of Flex
Array loudspeakers. The conversion frame has a SWL of 520kg which enables a column of up
to a maximum of 12 TFA-600H cabinets to be suspended below it.

The CF-600 conversion frame also functions as a ground stacking frame, interfacing between
ground stacked TFA-600L bass cabinets and the mid-high cabinets positioned on top.

The net weight of the conversion frame is 11kg (24.2lbs)

Connection to the first TFA-600H cabinet is made via two 10mm ball-lock pins which are
engaged into the rear spine of the mid/high cabinet (one pin is located on the loudspeaker
and one pin is located on the conversion frame).

The drop link from the TFA-600L low frequency cabinet is released by removing one of the
pins and pivoting the link into the conversion frame.

The drop link from the conversion frame locates into the clevis connection plate of the top
mid/high cabinet in one of several predetermined locations, which allows for a range of inter­cabinet angles.

Procedure for Flying a Column of Flex Array Loudspeakers

As described previously, the task of flying Flex Array cabinets is greatly simplified by the use
of the FT-600/3 transport case which allows three mid/high cabinets to be transported, pre­rigged and lifted out of the case in one block.

1. Having established the location of the rigging points, position the FB-600 flybar directly

underneath a fly point and check that the intended position of the cluster will give the
required coverage. Attach a chain motor to the lift point using the shackle provided. At
this point the lift point should be traversed so that it is approximately within the front half
of its travel.

2. Lift the flybar and position a FT-600/3 transport case underneath. Engage the flybar drop

links into the flygear of the first mid/high cabinet. Secure the drop links with the ball-lock
pins that are attached to each side of the first loudspeaker cabinet.

3. Lift the flybar together with the first three cabinets sufficiently to allow a further FT-600/3

transport case with three mid/high cabinets to be positioned underneath.

4. Locate the third cabinet‟s drop links into the flygear of the fourth cabinet and secure with

two BLP-8/15 ball-lock pins. Secure the rear drop link with a BLP-10/35 ball-lock pin.

5. Lift the flybar and continue to add cabinets either in blocks of three or singly as required

to complete the specified loudspeaker cluster.

6. Adjust the angles of the lower cabinets as you go, according to the cluster design; it is

much easier to do it now (lifting the weight of one or two cabinets by hand in order to
release the drop link and change its position) rather than trying to adjust cabinets in the
middle of a larger cluster.

7. Connect the NL8 speaker cables up the cabinets as you go along as well; they may not be

reachable later on. The cables will run neatly into the cable recesses in each speaker
cabinet.

8. The lowest cabinet‟s drop link is not used and should be parked in the rear woodwork

recess with a captive ball-lock pin as shown here.

9. Adjust the overall inclination of the cluster using a speed brace or electric drill applied to

the 22mm (7/8”) drive nut at the rear of the flybar. An inclinometer may be used on the
flybar or the top cabinet to obtain a consistent angle between the left and right PA
clusters.

10. Lock the lift point with BLP-10/100 100mm (4”) locking pin before lifting the flybar into its

final position.

LMS series Loudspeaker Management Systems

Introduction

This section is provided with the aim of assisting sound engineers, installers, and consultants
to fully understand Turbosound Loudspeaker Management Systems, and to obtain the full
benefit of their capabilities.

The Turbosound LMS-D26 and LMS-D24 are recommended for use with Flex Array
loudspeaker systems, offering varying features and facilities depending on the specific
application.

Unpacking

As part of Turbosound's system of quality control, the product is carefully checked before
packing, to ensure flawless appearance. After unpacking the unit, please inspect for any
physical damage. If any damage has occurred, please notify your dealer immediately, so that
a written claim for damages can be initiated. You, the consignee, must instigate any claim.
Please retain all packaging in case of future re-shipment.

There will be a small packet of spare fuses with the unit. Please keep them in a safe place.

Mechanical Installation

A vertical rack space of 1U (44mm / 1.75") is required for each unit. If used in a mobile or
transportable system, the unit must be supported at the rear by additional bracing or
shelving, to prevent vibration-induced metal fatigue of the racking „ears‟. Failure to do this
will impair reliability and invalidate the Warranty. The rack casing must have a depth of
425mm (minimum) to clear the connectors.

Adequate ventilation must be provided by allowing sufficient room around the sides and rear
of the unit to permit free circulation of air. Forced cooling is not required, a factor which aids
component longevity. The front of the unit should not be exposed to long term direct
sunlight as this can have a detrimental effect on the display lens.

Input Signal Indicators – A set of three pairs of LED‟s indicate signal present, +4dBu and input

clip for both channels. The signal present LED‟s operate at approximately –40 dBu, giving a
useful indication of even relatively low input signal levels. The +4 dBu LED‟s are intended to

show nominal operating level and can also be useful for setting system gain structure. Clip
LEDs warn the user of input overload and operate at +19 dBu.

Program Store and Recall – these controls provide access to 45 presets. Pressing the store
button allows the user to name a preset and choose which memory location it will be held in.
Pressing store button again completes the process. The Recall function operates in a similar
way, pressing the recall button allows the user to select which preset they require, pressing
the button for a second time, then confirming, recalls the new DSP settings. The unit allows
the user to set up user programs with full access to all parameters.

Note that presets cannot be stored or recalled when secure mode is activated.

Channel Selection Buttons – the currently selected channel is displayed on the top left hand
corner of the LCD. Pressing the channel buttons scrolls through the available input and
output channels and finally through the utility functions and back to the default screen. If
operating a stereo-linked preset the channel name will indicate the channel pairing. For

example „A+B‟ means both input A and B parameters. The name of the output will be shown

briefly at the top of the display when stepping onto an output.

Edit Select Buttons – the currently selected edit parameter is displayed on the bottom left
corner of the LCD. Pressing the edit select buttons moves through the available parameters
for the current input or output.

Text display – preset, channel, parameter and status information is shown on the 2x 24­character text display. In most screens the currently selected channel is displayed on the
upper line and the edit parameter on the lower line. To simplify the display and enhance
security, some parameters or parameter pages are omitted when not relevant.

Parameter Knobs – three velocity sensitive parameter knobs are used to adjust parameters
shown on the display. Up to three parameters are displayed on the screen. The parameter
name is shown above the parameter value in each of the three screen sections. The
parameter knobs have a fixed association with the screen sections; the rightmost parameter
knob adjusts the rightmost parameter and so on.

Output signal and limiter indication – two LED‟s are provided for each output channel. These
show the signal level relative to the limiter threshold. The yellow LED will light when the
signal is 6dB below the threshold and the red warning LED will light when the limiter
threshold is reached.

Mute buttons and status LED‟s – each output has a mute button and associated mute status
LED. Pressing the button toggles the mute on and off.

Note that the mute buttons do not function when the Secure Mode is activated.

Secure Button (on the rear) – a momentary button is fitted behind the rear panel, between
the output XLRs and the RS232 port. When activated, this will disable all the front panel
controls so they cannot affect the signal path, making the unit secure against tampering.
When in secure mode, the indicators still operate normally.

Note that the communications port is still active in secure mode.

Power Inlet – provides connection to a suitable mains electricity supply using the cable
supplied. The controller has a switch mode power supply that is capable of operating with a
nominal mains voltage of 80 to 240v, 50/60Hz without re-configuration.

Network card – connects to a PC via a BvNet interface to enable network control of the
loudspeaker system.

Audio Input connectors – these are fully balanced and are wired pin 1 ground, pin 2 hot and
pin 3 cold. The two inputs have pin 1 connected directly to the chassis and feed the signal
processing chains. If an unbalanced source is used, a connection should be made between
the pin 3 „cold‟ signal and the ground connection of the unbalanced source.

Audio Output connectors – the processed outputs are impedance balanced, and are wired
pin 1 ground, pin 2 hot and pin 3 cold. An unbalanced input may be driven by connecting pin
3 „cold‟ signal to the ground connection of the unbalanced destination input. Note that output
pin-1s are ground lifted at audio frequencies but connected to ground at RF for good EMC
performance. The intention being that the amplifiers the processor is driving should be
responsible for the grounding of their input cable shields.

Communications port connector – the unit may be controlled entirely from another
controller (typically a Personal Computer), running an application that is compliant with the
ObCom standard. Connection will normally be made to the controller via this serial port
connector. This port is also used for updating the firmware in the unit.

Note: The communications port is NOT disabled when the front panel is made secure using
the secure button.

Operating the LMS-D24 and D26

Starting up

The unit will energise as soon as power is applied to the IEC inlet; there is no power switch.
During the start up process the firmware application model number and version numbers are
displayed and the outputs are muted until the unit has completed its internal checks. Once
the start-up routines are complete and the unit is ready to pass audio, the DSP signal path
will be restored to the current settings when it was last powered down and the audio signal
is gradually ramped up to its correct level.

Selecting a Factory Preset

There is a library of thirty Factory Presets to suit a range of Turbosound enclosures.

Factory Presets contain some parameters that are fixed and hidden from view; the remainder
of the DSP parameters are available for user manipulation. The number and type of hidden
parameters is dependant on the Factory Preset, typically crossover frequencies, output delay
and some EQs are hidden; those settings that are a function of the loudspeaker cabinet
design and should not require adjustment for different applications.

To recall a Factory Preset for a particular cabinet or system, press Recall and use the left hand
parameter knob A to scroll through the available factory preset locations (as indicated by a
box symbol after the preset number). Once the appropriate preset has been selected press
recall again, at which point you will be asked to confirm the action by pressing recall for a
third time. This is to guard against accidental recall of Presets.

Factory Presets are locked so they cannot be over-written. The user can, however, store an
edited version of a Factory Preset in any free preset location.

Details of all the Factory Presets can be found in Appendix A.

Creating a Crossover

In addition to the Factory Presets the unit has two further „Base Presets‟; mono and stereo.
These Base Presets are stored in locations 1 and 2 respectively, they can be used to develop
settings for any loudspeaker combination and are recalled in the same way as the Factory
Presets described above. These Presets are also locked but the user can name and store their
own edited versions in any free preset location.

Navigation and Viewing Parameters

(Note: The LMS-D26 is shown in all the following screen shots; however the features and
parameters apply equally to the LMS-D24)

Many of the processing elements in each input and output path have features that may be
controlled by the user, such as gain, frequency or limiter threshold. We call these adjustable
features parameters.

A parameter may be adjusted when it is displayed by turning one of the three-parameter
knobs. Each of the three-parameter knobs is associated with a zone on the display. Adjusting
the leftmost parameter knob will change the value of the parameter showing in the leftmost
zone of the display and so on. Turn a knob clockwise to increase the value of a parameter, or
anti-clockwise to decrease it. The knobs are velocity-sensitive so turning a knob rapidly will
cause the action to „accelerate‟, so the value changes more rapidly.

Navigation

The DSP parameters are organised by channel. The currently selected channel is shown in
the top left hand corner of the display. You can navigate between the channels by pressing
the channel buttons. Pressing the channel buttons will scroll through the channels, utilities
and back to the default screen. When using a Preset that is stereo linked, the channel

selection will reflect this. For example „1&4‟ indicates outputs 1 and 4. When navigating onto

an output channel, the usage of the output, as define in the factory preset, will be shown
briefly at the top of the screen.

Pressing the edit navigation buttons gives access to the various pages of parameters
available for each channel. The currently selected page is shown in the bottom left hand
corner of the display; this is omitted on some pages where the function is obvious. The
screen shows up to three (normally related) parameters for a given part of the processing
functions on a given channel.

The edit buttons allow you to scroll, in either direction, through the different processing
pages for a given Channel. When you go past the last page, you will be returned to the
default page.

The channel buttons allow you to scroll, in either direction, through the input and output
channels, whilst trying to maintain the currently viewed processing block. If the channel you
scroll to does not have the currently viewed processing block, the next one will be shown
instead.

NB. When the unit powers-up, the settings will be the same as those when the unit was last
switched off.

Stereo / Mono Formats

There is only one „standard‟ layout of the processing blocks, but flexible routing and control

linking allows this layout to be adapted to a wide variety of applications.

There are two „Formats‟, Mono or Stereo. With the Mono format, all outputs have unique

parameter settings, and all outputs are identical in terms of processing functions and routing
capability. This is the most flexible Format.

Stereo format pairs the inputs and outputs for stereo operation, the parameters of each
member of the pair being identical. The routing of inputs to outputs is fixed. This format is
intended for symmetrical stereo operation, eliminating the need to make identical parameter
adjustments for each channel.

The channel pairing is:

Left and Right Inputs

Outputs 1 (routed from L input) and 3 (routed from R input) [1 and 4 for LMS-D26]

Outputs 2 (routed from L input) and 4 (routed from R input) [2 and 5 for LMS-D26]

Outputs 3 (routed from L input) and 6 (routed from R input) – LMS-D26 only]

high pass filtering as it affects all outputs and can therefore improve inter-band phase
relationships. Filter type is selectable from Butterworth, Bessel, Linkwitz-Riley and Hardman.
Filter slopes of up to 4th order or 24dB / octave are provided. Not all filter types are available
in all slopes. For example 18dB / octave Linkwitz-Riley filters do not exist.

The Hardman type filter is always described by its‟ order as the filter becomes progressively

steeper rather than following a linear slope so a dB/octave description is not accurate.

Mechanical Installation

When supplied as part of the AMP-890.2 system rack, the amplifiers are pre-installed. If an
amplifier is removed from the rack for any reason, it is important to re-install it correctly. The
amplifiers must be supported at the front and rear, as originally supplied. Failure to support it
adequately may eventually result in vibration-induced metal fatigue of the rack mounting
ears and such damage will not be covered by the warranty.

Adequate ventilation is essential, both at the rear of the rack, the sides, and also at the front.
This should be considered carefully when placing covers around the racks for protection from
inclement weather at outdoor events, or when using blacks to mask them from view. If the
venting is inadequate, the amplifier's temperature metering will display this.

CAUTION: Air emerging from the amplifier's high efficiency heat-exchangers can reach 60C
to 70C. To prevent personal injury or fire, please ensure that people and combustible or
flammable materials (e.g. plastic waterproofing, newspaper, clothing, costumes, solvents)
are kept at least 2'/0.6m from the amplifier's exhaust outlets. If venting is inadequate, the hot
air can adversely affect other equipment, and may soften some thermoplastic enclosures. If
using plastic coated cables, take care to dress the leads away from the airflow. Professional­grade rubber cables are not affected.

Mains Power

The T series amplifiers will operate from any international 50 - 60Hz AC mains supply
between 110-120 V and 220-240 V. Separate models are supplied to match local mains supply
requirements.

Powering Up

When the amplifier is switched on by depressing the black POWER rocker switch, the
protection circuit will initially activate whilst the circuits stabilise. Assuming no faults are
detected the POWER LED (and the signal LED if signal is present) will light up after a few
seconds.

Safety Earthing

The Green/Yellow wire on the T-25 and T-45‟s mains cord must always be connected to the
electrical installation's safety Earth (or Ground). It is essential for personal safety. The rack
framework is connected to the same grounding circuit.

user manual

FLEX ARRAY

FLEX ARRAY user manual

Page 69

Voltage Setting

Your models will be set up at the factory for correct operation on your local voltage supply.
No further adjustment is necessary.

Voltage Range

The minimum supply voltage over which the amplifier will operate is 180V for the 220-240V
range, and 90V for the 110-120V range. Naturally, maximum power output will be reduced
accordingly from the published ratings.

The maximum supply voltage which exceeds safe limits and causes the amplifiers to switch­off is in excess of 260 V for 220/240 V range, and 130 V for the 108/120 V range. This is
however dependent on load impedance and program drive level as mentioned above.

Obviously, the mains voltage will reach these limits only in exceptional circumstances and
the A/P (Audio Protect) LED will then flash.

Audio Connections & Controls

The amplifiers‟ actively balanced, fully-floating input connections are fuss-free, regardless of
the installation's complexity.

The incoming 3-pin XLR plug should be connected, with a high grade twin-core screened
cable, as follows.

Pin 1

Screen - connect to shield

Pin 2

hot (signal +)

Pin 3

cold (signal -)

The shield connection to pin 1 at each amplifier input must be maintained under all
circumstances, as TURBOSOUND will not be responsible for consequential damage arising to
loudspeakers, etc., should this connection not be made.

The amplifiers are designed to operate with fully balanced equipment. Ground loops or loss
of performance may be experienced if connected to unbalanced sources. If it is unavoidable,
however, the following wiring convention should be used.

FLEX ARRAY

FLEX ARRAY user manual
Page 70

Pin 1

Screen - connect to chassis of the unbalanced
equipment, or left disconnected at the unbalanced end

Pin 2

signal hot

Pin 3

Signal cold

Polarity

In accordance with international standards, T series amplifiers are supplied with Pin 2 hot (+),
so a positive (+V) input gives a positive (+V) output from the positive (+) output terminals.

Input Impedance

Each amplifier channel has an input impedance of 10k, seen between pins 2 & 3 of the XLR.

When used with the LMS-D2x Loudspeaker Management System, distribution amplifiers are
not required when a large number of T-25 or T-45 amplifier inputs are driven in parallel.

Gain and Sensitivity Settings

Gain settings are changed internally by simple jumper links. Two rows of pins marked - GAIN
A and GAIN B - are situated on the input PCB (PCB701). A jumper link sets the gain and the
settings are as follows:

Link 1 & 2

Gives 32dB gain

Link 3 & 4

Gives 26dB gain

Link 2 & 3

Gives approx 37.5dB gain

NOTE: Factory setting is normally link 1 & 2 = 32dB gain.

Setting higher gain does not change the maximum available power but changes the level of
signal input to achieve maximum power. In any case, provided that the input signal is less
than 20dBu/7.7V, the built in limiter circuit will prevent distortion within the amplifier.

The gain should be set to match the signal from the source, e.g. mixer, controller, or
equaliser.

user manual

FLEX ARRAY

FLEX ARRAY user manual

Page 71

Attenuation & Gain Setting

The front panel gain controls allow precise level settings, and may be used to adjust the
relative levels of sections of a large system, for example downfills or side seating cover in an
arena.

The front panel gain controls are also useful when initially checking a system after it has
been connected up.

Note that in BRIDGED mode only the Channel A control is active.

Output Connections

A Speakon NL4 connector is provided on each channel.

Damping Factor

The T series amplifier outputs provide a high damping factor, typically 400 times at low audio
frequencies. This damping helps the amplifier to control the loudspeaker drive units,
provided that the resistance of the intervening cables and connectors is very low. The sonic
benefits of high damping factor are most pronounced at bass and low-midrange frequencies
(i.e. 10 to 600Hz) providing a subjectively tighter sound as a result of the improved
reproduction of transients.

Amplifier damping factor is degraded by high resistance in the loudspeaker circuits; i.e. thin
conductors, long output cable runs and tarnished, corroded or loose connections.

Damping factor is maximised by installing cables containing conductors of large cross­sectional area, and by specifying connectors with heavy-duty contacts and waterproof covers.

user manual

FLEX ARRAY

FLEX ARRAY user manual

Long Speaker Lines

Whenever loudspeakers are connected to power amplifiers by long cables (above 20'/6m),
there is invariably an increased risk of high frequency instability. It is aggravated by the
combination of RF pickup in unshielded cables acting as aerials, and multiple complex
reactance in the cable and loudspeakers.

High frequency instability can be avoided by adopting these common sense rules:

Ensure the input wires are shielded and that the shield is connected to the amplifier's input
XLR pin 1.

Do not run output cables next to input signal lines. Keep them apart, and preferably cross
them at right angles. If cables have to follow a similar route or path, keep them separated by
at least 2 feet (0.6m).

The Cooling System

The cooling fans respond to temperature sensors within the unit to maintain a safe operating
temperature. In the event of excessive temperature, the protection circuit will operate,
disabling the output. The red „AUDIO-PROTECT‟ (A/P) LED will indicate this condition (see
fault indicator.)

There are 4 fans connected permanently with variable speed and a jumper link to enable
them from cold.

Normal dynamic signals will not cause the amplifier to overheat unless the ventilation is
inadequate. (See installation section and maintenance section.)

Use of thread locking compounds

The flygear on the rear of the cabinet should be inspected regularly, and all bolts should be
tightened where necessary. It is advisable to use thread-locking compounds on these fixings
in order to avoid any long-term possibility of loosening.

The recommended thread-locking compound is Loctite 222. The corresponding activator,
Loctite 7471, should be used to achieve 100% performance.

Application: Spray Loctite 7471 into the thread holes and allow to evaporate. Apply Loctite
222 thread locking compound to the bolts prior to fitting, allowing sufficient to fill all the
engaged threads. Assemble components and tighten as necessary.
