Product Range Summary
General Features
TCS Compact series loudspeakers are designed for use in a wide variety of fixed
installation applications that require professional sound quality, ranging from cafés,
pubs, bars and restaurants to retail stores, nightclubs, live music venues and houses of
worship.
• Cabinets are constructed from high quality birch plywood; rebated, glued and
screwed together for maximum strength and rigidity.
• The enclosures are supplied with a durable black or white semi-matt textured
paint finish as standard. Optional finishes include TurboBlue™ and a whole
spectrum of other custom colours. Cabinets can also be supplied in raw birch
plywood for painting, varnishing or staining on site to match venue décor
requirements.
• Powder-coated perforated steel mesh grilles, backed with reticulated foam (or
white acoustically transparent cloth on white cabinets) protect the drive units
from damage and provide an unobtrusive and aesthetically pleasing apperance.
• Multiple rigging points enable a wide variety of installation methods: with
standard eyebolts, OmniMount™ hardware and specifically created Turbosound
wall and ceiling brackets. The enclosures are fitted with internal M10 threaded
rigging points on the top, sides, bottom and rear, that allow single cabinets to be
suspended and angled in fixed installations.
• High quality components are used throughout. Cast-frame low frequency drivers
give the combined benefits of high strength and low weight.
• Speakon NL4MP connectors and 4-way terminal / barrier strips are provided on
recessed rear panels for input and loop-through / parallel connections to
additional TCS Compact series speakers.
• Weather-resistant options, to IP54 rating (protected against dust and sprays of
water from all directions), enable the TCS Compact series to be used outdoors or
in humid conditions.

TCS Compact series
General Features for Two Way Enclosures
• High-grade speaker components are matched with an internal passive crossover
to ensure a seamless transition between the HF and LF drivers.
• The crossover network incorporates a two-stage thermal overload protection
system which prevents damage to the high frequency driver by reacting
instantly to large transient peaks while still allowing wide dynamic range to be
maintained. The protection system is transparent at normal operating levels and,
as the level increases, the signal is gradually and almost imperceptibly
compressed once the critical threshold has been reached.
• High frequency drivers have been selected for consistent and reliable
performance.
• High power line transformer versions are optionally available for use in 70v or
100v line distributed systems.
user manual
• The rigging points on the bottom of the cabinets enable them to be hung upside
down in order to position the HF driver closer to the audience.
• TCS Compact Series full-range enclosures are designed to give good pattern
control down to crossover frequency, and are fully supported with EASE polar
data (available to download from the Turbosound website at
www.turbosound.com). This enables accurate and predictable results when
specifying sound systems in a given venue.

System Considerations
Choosing the best location
When using any loudspeaker system certain room parameters will affect the resultant
sound quality and coverage. For example, any boundary like a wall or floor will lift certain
frequencies. If you are placing speakers in a corner, then a lift at the bass end is to be
expected and it may sound rather ‘boomy’. This can be compensated for by moving the
speaker or cutting low frequencies with an equaliser.
TCS Compact series speakers are designed to be flown in free space or mounted on
specialist wall and ceiling brackets. When speakers are flown in free space then
boundary effects are minimised. The result is a smooth frequency response without any
boost at odd frequencies, but the bass end may appear subjectively light. In this case
increase the sub-bass level to bring the low end up or add sub bass enclosures as
necessary.
Dispersion
TCS COMPACT series enclosures are designed to provide respectably wide horizontal
coverage; the TCS-151C and TCS-121C offer 70° and the TCS-101C and TCS-081C 100° .
This allows the majority of live sound applications to be covered with single enclosures
placed individually to take advantage of this performance feature, for example either side
of a stage in a pub, or small club environment, as shown below.
tcs compact manual
page 14
TCS Compact series
Calculating the sound pressure level at a known distance from the PA
Sound intensity reduces rapidly as the distance from the source increases according to
the inverse square law which, predicts that a doubling of distance will result in a
reduction of ¼ the original, equal to a drop of 6dB, providing there are no reflections or
reverberation. For every 3dB increase of speaker output you need a doubling of input
power.
For example, in an open space where the front seats are 6 meters (20 ft) from the sound
source and the back seats are 60m (200 ft) from the sound source, you would expect the
sound pressure to drop by a factor of 100 (= 20 decibels) between the front seats and the
back seats.
In a ‘real world’ enclosed auditorium, this reduction is partially mitigated by the effects of
reverberation in the distant field and, in the near field, because the speaker looks more
like a wall source than a point source. Therefore the sound field in a room only behaves
according to the inverse square law in a relatively narrow distanced range.
user manual
It should be possible to make considered decisions regarding the particular models of
speakers that are required based on their sensitivity and SPL (sound pressure level) in
order to achieve the desired coverage and level.
Equalisation
TCS COMPACT series enclosures are designed to provide smooth and even frequency
response. They do not need excessive amounts of external equalisation to overcome the
sonic deficiencies often found in many lesser designs.
In order to compensate for room acoustics, TCS Compact series enclosures require only
minimal equalisation. As in any system, over-equalisation introduces phase shifts,
distortion and a reduction in headroom, usually causing more problems than it cures. It is
good practice to use as little equalization as possible, aiming to ‘cut’ frequencies rather
than adding large amounts of ‘boost’.
Most rooms will have resonances that will be excited at particular frequencies needing
some cut to help tame the sound. These problems are most pronounced at the lower
frequencies where loudspeakers generally exhibit very little directional control. Under
most circumstances a 1/3 or 1/2 octave graphic equaliser will generally be adequate, with
the fader settings applied smoothly and sparingly for the required room compensation.
If you find that the system needs a lot of boost at lower frequencies you probably need
additional sub-bass units.
tcs compact manual

user manual
TCS Compact series
Amplifier Requirements
Turbosound loudspeaker enclosures should be driven by high quality power amplifiers
designed for true professional use. Such amplifiers will have balanced inputs, DC and RF
fault protection, and well designed cooling systems for reliability.
The ‘program’ power, listed in the loudspeaker’s technical specification, is the best guide
to the size of amplifier required for general purpose applications. The amplifier should be
capable of delivering long term broadband power equal to the loudspeaker’s program
power rating at the loudspeaker’s stated nominal impedance. This approach allows
sufficient headroom to generate good dynamic range.
RECOMMENDED AMPLIFIER POWER RATINGS:
The amplifier's rated r.m.s. continuous power output (20Hz – 20kHz, per
channel) should be equal to the program power handling of the
loudspeaker at its nominal impedance.
It should be understood that overdriving an insufficiently powered amplifier is more likely
to cause loudspeaker damage – the total energy in a heavily clipped signal is far higher
than in an unclipped signal – than operating a more powerful amplifier within its ratings.
In general, the more powerful the amplifier the better it will sound, provided that it is not
also driven into sustained clipping.
All the equipment in the system before the system controller should be set up for 0dBV
(775mV) maximum output. One controller can be used to feed several amplifiers as long
as all the amplifiers are the same (or have the same gain ratings). More than one
controller may be required if the amplifiers are of different gain or type. Please contact
your dealer if you require help in this area.
Turbosound recommends the T-series amplifiers for use with the TCS Compact series
system.

System Configurations
TCS Compact Series 2-way enclosures are passive loudspeaker systems. This means that
they require only one amplifier channel for correct operation, the frequency splitting
between the low frequency driver and the high frequency driver being accomplished by
the internal passive crossover network in each enclosure. If subwoofers are used in a biamplified system in conjunction with TCS Compact Series 2-way enclosures, additional
amplifier channels and external electronic crossovers will be required. The Turbosound
LMS-D24/26 digital management systems are recommended for this purpose.
Many different system configurations of TCS Compact Series loudspeaker enclosures are
possible to suit various installation requirements, ranging from cafes, bars and
restaurants to theme parks, theatres and houses of worship. Listed below are a few
common examples.
System1 – Basic stereo set up

EQ
POWER AMPLIFIER
A single amplifier supporting two TCS Compact series 2-way speakers creates a standard
stereo system. A further pair of TCS mid/tops could be connected using the loop-through
connections, although this will result in a corresponding drop in impedance. With TCS
Compact 2-way speakers with a nominal impedance of 8 ohms this would make a
combined 4 ohm load that should be suitable for any good quality power amplifier (see
amplifier considerations for more information).
NB: A stereo configuration is shown but this system could be run in mono.

BASS
In this case a crossover is needed to separate the bass and mid / high frequencies. The
Turbosound LMS series is recommended as the units are preconfigured with presets to
match the TCS Compact series requirements.
This system can be scaled up with the addition of further amplifiers and processors. If
using the LMS-D26 processor there will be two extra channels available for adding say
another pair of mid/top cabinets through an extra stereo power amplifier.
If using TCS-218C or TCS-215C dual-driver bass bins then note that the impedance for
each of these is already 4 ohms and only some very powerful amplifiers are capable of
driving loads at 2 ohms or below. Consider using extra amplifiers for this purpose rather
than the loop through connections. The TCS-115C or TCS-118C bass speakers are 8 ohms
so it is possible to run two cabinets from one amplifier, providing the amplifier is
powerful enough, although extra amplifiers will still provide the best performance.
tcs compact manual
page 18
It is recommended to use a bass cabinet and a mid/top with each stereo amplifier as this
helps distribute the load across the power supplies better.
NB: The EQ shown is for tuning the system to the room / venue.
TCS Compact series
Crossovers and Processors
In order to correctly set up your sound system a selection of audio processing devices are
necessary to divide the frequencies between the speakers, apply equalisation and limit
the dynamic headroom. These duties can be performed by proprietary units such as
standalone crossovers, graphic equalisers and limiters, and a TCS Compact series
installation can be built in this way by paying careful attention to details such as
appropriate crossover settings. This information is provided in the Technical
Specifications for each TCS Compact series speaker.
Active and Passive systems
Passive crossover networks split the frequency range between drivers after the amplifier.
Although this an economical method for many general purpose applications, problems
associated with this approach include the loss of energy (watts) as heat in the
components of the crossover. Also, it is not possible to design steep roll-offs, as a broad
range of frequencies has to be covered by both components. This causes smearing
between the drivers and potentially raises the distortion from the individual components.
If the headroom limit of the amplifier is reached the HF component can be heard
,
‘pumping’
as large amounts of energy are consumed by the low frequency transients.
user manual
In an active system the crossover is placed before the amplifiers to gain particular
advantages. More amplifier channels are needed to deal with the split of frequency bands
but this separation also helps to deliver a cleaner, more controlled sound from the
speakers. The HF cannot be modulated by power drains needed by the LF speakers.
Loudspeaker Management Systems
The concept of a Loudspeaker Management System is to provide all the processing
electronics you might need in one box. This typically includes crossover functions,
equalisation, limiters, delays and preset memories, that can store different set ups for
various applications. A loudspeaker management system offers potentially better audio
quality, more precise control and protection against unwanted changes in settings.
Digital processing enables steeper roll-offs through the crossover areas to be designed,
allowing more output from the speakers, as they are individually handling more
appropriate bandwidths. Also, the addition of delay to the LF signal to match the arrival
of the HF can help to make the image more intelligible. Therefore, it is much easier, and
more efficient, to manipulate audio digitally in low voltage electronics than in the passive
crossover networks found inside speakers.
The TCS Compact series has a range of sub bass units (TCS-115C, TCS-118C, TCS-215C,
TCS-218C) that are designed to be used actively with the mid/top cabinets (TCS-081C,
TCS-101C, TCS-121C, TCS-151C). The Turbosound LMS-D24 and LMS-D26 loudspeaker
management systems contain custom presets for the TCS Compact series along with a
world-class audio specification.

Turbosound LMS series loudspeaker management systems
The Turbosound LMS-D24 and LMS-D26 series are powerful DSP-based audio processing
units designed for use with Turbosound loudspeaker systems and associated bass
enclosures. The functions of multiple conventional products are combined in a compact
1U high 19” rack unit. They offer EQ, both for the room and the drivers, delay to align the
wave front, and limiters that can be set for each individual component to ensure against
damage and to protect the long term reliability of your speakers.
The LMS-D26 has two inputs and six outputs and the LMS-D24 has four outputs. The
units are configured to provide specific equalisation and crossover points aimed at
optimizing the performance of these Turbosound loudspeaker systems. In addition,
limiters, delays, eq, gain, polarity, and crossover filter controls are accessible to the user
in order to match specific operation environments. The LMS series crossovers are
designed for quick setup and adjustment via easy-to use front panel controls and, are
ideally suited to both live sound and fixed installation.
Features
• Minimal signal path design, providing exceptional audio quality with carefully
optimised processing and high performance converters for a >111dB dynamic
range.
• Sonically superb ADC / DAC combination; a carefully matched pairing of the best

LMS-D24/6 Quick Reference Set Up
(LMS-D26 shown)
The LMS-D24 and LMS-D26 are designed for quick setup and adjustment via an easy-touse menu structure accessed by front panel buttons and 3 rotary encoders. A high
resolution backlit LCD display provides the user interface to the menu options and
parameters being adjusted.
Input Signal Indicators - three pairs of LED’s indicate signal present, +4dBu and input clip
for both channels. The signal present LED’s operate at approximately –40dBu, giving a
useful indication of even relatively low input signal levels. The +4dBu 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 +19dBu.
Starting up
user manual
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. At this stage the display
shows the default screen with the memory location and name of the current Preset on the
lower line of text.
About Presets
The unit has 45 memory locations and there is a library of around thirty ‘Factory’ Presets
to suit a range of Turbosound enclosures. Factory Presets are locked so they cannot be
over-written although edited versions can be stored in the free preset locations. Details of
all the Factory Presets can be found in Appendix A in the LMSD2x pdf in the downloads
section of www.turbosound.com.
Factory Presets contain some parameters that are fixed and hidden from view; typically
crossover frequencies, output delay and some EQs; those settings that are a function of
the loudspeaker cabinet design and should not require adjustment for different
applications. The number and type of hidden parameters is dependant on the Factory
Preset. The remainder of the DSP parameters are available for user manipulation.

Preset Recall
• To select a Preset, press the Recall Button so the indicator above it illuminates.
• Turn the left of the three parameter knobs (a) until the required Preset number is
shown on the display.
NB: Factory presets are indicated by a box symbol appearing after the Preset
number.
• Press the Recall Button again to activate the Preset.
NB: Pressing any other button will cancel the operation.
This process is deliberately in three stages in order to guard against accidental recall of
incorrect Presets.
Creating a user defined crossover
In addition to the Factory Presets the unit has two further ‘Base Presets’ for mono and
stereo usage. 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.
Store button
tcs compact manual
page 22
To store a preset in a location, press the store button and use the encoders to select the
memory location and name the preset. Pressing the store button again completes the
task. Pressing any button other than store during the process cancels the procedure.
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.

LMS-D24/D26 Audio Connections
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 pins 1 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.
user manual
Presets and Secure mode
A momentary button is fitted on 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 however; Presets cannot be stored or recalled. If the unit
is not responding then check that Secure Mode is not active.
Note that the communications port is still active in secure mode.

Please take care if XLRs, binding posts, or other dual connector systems, are used at the
amplifier end of the loudspeaker cables (jack plugs/sockets should not be used) where
there is a possibility of the cables being reversed. It is highly recommended that Neutrik
Speakon or other heavy duty non-reversible connectors are used.

Cable Recommendations
Heavy duty loudspeaker cable should always be used, with a minimum wire size of 12
gauge (1.5mm²), and preferably 10 gauge (2.5mm²) for longer runs, keeping the run as
short as possible. This helps to avoid wasting amplifier power in the resistance of the
cable. High cable resistance also lowers the damping factor of the amplifier which affects
its ability to control loudspeaker cone movement.
Losses due to undersized cable and long runs are clearly illustrated in the table below.
Please use this table to determine the most suitable cable size and maximum run for your
particular application.

Flying & Lifting / Rigging
A versatile set of rigging parts has been designed for TCS Compact Series enclosures in
order to give the installer a cost effective approach to flying and mounting, ranging from
a single enclosure up to multi-box arrays and clusters.
All riggable products are fitted with metric internal fixings. It is expected that external
parts such as eye nuts, flying bridles, scaffold clamps, safety chains etc. will be obtained
locally from the usual suppliers and used with the parts available from Turbosound.
Any installation, whether temporary or permanent, must be securely attached to the
structure of the building using chain, steel wires or web straps which are certified and
load rated for the purpose. The combined weight of the sound system, its cables and the
rigging system must be safely carried by the points at which attachment is made to the
building or structure. Great care must be taken in selecting the attachment points and
methods, being absolutely sure of the load carrying capacity of points chosen.
user manual
IMPORTANT NOTE: The rigging of loudspeaker systems is an extremely serious matter
with potentially lethal consequences should anything go wrong. It is of vital importance
that you, or other people rigging the system, are suitably qualified to do so and have a
full understanding of all the factors involved with safety as a number one priority.
Turbosound accept no responsibility for any accident, damage or failure of any rigged
system. This rigging information is specifically related to the requirements of the TCS
Compact Series products only. For more detailed information on the whole topic of
rigging various handbooks are available. If you are in any doubt contact your
Turbosound dealer who will be able to refer you to an experienced rigging company.
All the sets and parts have been type tested and will be covered by ‘certificates of
conformity’ as to their ability to safely meet their design specification. These certificates
are available on request.

Flying Single Enclosures
Single enclosures may be flown using a variety of different methods:
M10 eyebolts
All TCS COMPACT series cabinets, including low frequency enclosures, can be rigged in
permanent installations using optional M10 shoulder eyebolts (available from
Turbosound or third party suppliers). These can be attached to the rigging points
provided on the top and back of the cabinet. The rigging point at the rear of the cabinet is
used to alter the downward angle of the enclosure.

As supplied, these rigging points are fitted externally with M10 countersunk slot-head
screws. To facilitate rigging of the enclosure simply remove these M10 screws and
replace them with M10 x 18mm shoulder eyebolts using a suitable thread locking
compound to avoid the possibility of loosening.
Note: Eyebolts must have a thread length of at least 18mm (3/4”).
NOTE: The rigging points are designed to suspend single enclosures only. There is no
facility to hang an additional cabinet below a flown TCS COMPACT series enclosure.

Use of Thread Locking Compounds
When assembling flying hardware to TCS Compact Series loudspeaker enclosures it is
advisable to use thread-locking compounds to eyebolts and other bolts in order to avoid
any possibility of loosening.
The recommended thread-locking compound is Loctite 222.
The threaded rigging points used in TCS Compact Series enclosures are manufactured
from zinc-plated mild steel. Therefore, and additionally if the external bolts used are zincplated, zinc-passivated, stainless steel or anodised (as the majority are), then 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.
The parts may be disassembled by hand if required.

Servicing Information
If any of the drive units in your TCS COMPACT series cabinet should cease functioning
and need a replacement re-cone or diaphragm, you are advised to remove the faulty unit
from the cabinet and send it to a professional service centre authorised to repair
Turbosound loudspeakers.

user manual
The perforated steel loudspeaker grille (1) is held in place under tension only, fitting into
slots at either side of the baffle. There are no screws or other fixings holding the grille in
place. Lay the cabinet on its back and, using two small screwdrivers inserted through the
mesh of the grille, firmly pull the grille away from the slot at one side of the baffle until it
is free. Set the grille aside for later re-assembly.
Undo the screws (2) holding the driver in place and carefully lift it out and away from the
cabinet. Make a note of the driver terminal polarity for later reconnection. Disconnect the
cables from the drive unit and completely remove the driver from the cabinet being
careful not to damage the cone or suspension. Do not place the driver near to any
equipment or media that may be adversely affected by strong magnetism, e.g. CRT
monitors or magnetic tape of any kind.
To reinstate the speaker simply reverse the above procedure, making sure you observe
the correct polarity when reconnecting the cables back into the terminals of the drive
units.

About EASE Data
Sound system projects are more likely to go to plan when you have a reliable indicator in
advance of how the speaker system will perform in the venue. Turbosound engineers are
able to assist you with your system design using the industry-standard EASE program to
aid in the quest to find the perfect system for the job. Although we cannot replace the
role of an acoustical consultant, we can provide a good indication of system performance
to back up the proposal.
Statistically, more jobs are won and more sales are made when a project has been
properly and scientifically designed, along with the facility to show the client a convincing
visual representation of the finished design. This cuts a large amount of guesswork out of
the process, and is the reason why we actively encourage you to make use of our design
resources to help you or your customers to win that next job. EASE is also a useful tool
for addressing acoustic issues in the venue, for example to justify adding acoustic
treatment to a room such as cladding a wall or balcony face. Having a graphical model
can strengthen the proposal and ultimately ensure a better result.
user manual
Overview
EASE (Enhanced Acoustic Simulator for Engineers) is a sophisticated sound system
design tool and acoustic simulation software package for Windows PCs, created by SDA
(Software Design Ahmert GmbH, Berlin). It enables extremely accurate acoustic
calculations to be realised both for indoor venues and outside spaces. In this way
acoustic parameters and properties can be calculated for audience areas or even
particular listener seats. EASE is particularly useful where a large number of speakers
may be used, i.e. in concert halls, stadiums and public buildings.
The EASE application itself is comprehensive and can account for a wide range of surface
properties, i.e. absorption and dispersion and also early reflections, directivity and phase
characteristics. 3D acoustical models can be created for computing parameters such as
RT (Reverb Time), IR (Impulse Response) and SPL (Sound Pressure Level) distribution for
sound reinforcement and speech intelligibility.
There are a variety of module upgrades that enhance EASE’s capabilities, such as AURA
(Analysis Utility for Room Acoustics) which has become a standard for modelling spaces
in three dimensions along with the VISION rendering engine. EASE VIEW loads OpenGL
and Mapping files as used in the design
EARS is an auralisation module that allows the determination of audio quality, and the
comparison of old against new sound system installs, by locating sound sources in the
virtual room, or open air space, using convolving and binaural techniques.
tcs compact manual

user manual
TCS Compact series
EASERA is used for evaluating and measuring the transmission properties of both spaces
and electrical equipment.
EASE FOCUS is a free 2D ‘aiming’ program that can be used for aligning speaker stacks
and particularly arrays. It uses configuration files in ASCII format made using compiler
software which have the extension .efo.
Use of Turbosound EASE data
Turbosound provides pre-measured EASE data to aid sound system designers in making
appropriate choices with the type and positioning of speakers in the required venue. The
suitability of certain models can be assessed and the installation can be improved by
adapting the frequency response consequently.
The speakers are measured from the centre of an entire globe with 5 degree resolution
and third octave frequency resolution.
EASE data is available from our download FTP server at ftp://ftp.turbsound.com
