Components

  • The new 21" transducer developed for the TTS56-A sub represents the most powerful woofer ever manufactured by RCF delivering the cleanest, punchiest and undistorted low frequencies reproduction event at the most extreme sound pressure levels required by large scale applications.

Voice coil

  • The 4.5" inside/outside voice coil is wounded on a strong fibreglass former and guarantees a more efficient cooling. The former is internally and externally reinforced with Nomex that stiffen the overall structure for a better energy transfer between the voice coil and the body cone.

Hyper Ventilation System

  • In order to dissipate the heat generated by the powerful 4.5" voice coil, RCF engineers have developed a unique ventilation system that offers the best thermal dissipation and the lowest power compression. The Hyper Ventilation System is the result of a complex combination of holes in the voice coil former, in the magnetic structure and in the woofer basket. In fact, thanks to the large excursion of the cone, the great amount of air generated is directed through the holes creating a very high level of turbulence that keeps the transducer cooler without using a forced ventilation system. Thanks to the amazing strength of the voice coil former, obtained with the double Nomex layer, RCF engineers were able to make bigger holes without compromising the structure stiffness and therefore allowing the passage of a greater quantity of air, which would have not been possible with standard formers.

carbon fiber cone

  • The cone is composed of 30% carbon fibre, 20% fibreglass and 50% cellulose pulp. This particular chemical composition has been carefully developed to improve the robustness and rigidness of the cone avoiding any deformation that would result in a loss of efficiency.

Double silicon spider

  • The structure has been realized with 3 layers. The central layer is made of silicon which is the only material able to maintain the memory of its shape. This particular structure guarantees the perfect efficiency of the suspension even after a long period of extensive use.

Water resistant baltic birch plywood

  • The cabinet is made in high quality Baltic Birch plywood with every layer glued with a special water resistant adhesive that makes the cabinet completely waterproof.

Heavy duty polyurea paint

  • The paint department inside our factory in Italy utilizes a special polyurea paint to create a very thick full coating of the cabinet making it highly resistant to scratches and bumps.
Front grille
  • Reinforced front grille with foam back

REINFORCED GRILLE

  • The heavy duty front grille integrates a central reinforcement bar and is power coated. A special transparent-to-sound foam backing on the inside of the grille helps to further protect the transducers from dust.

Internal structure

  • The internal structure of the cabinet is heavily braced to survive long term use and transportation and presents two separate acoustic chambers for the woofers and a separate housing for the amplifier to guarantee the best components efficiency and reliability.

Wheels

  • 4 threaded high quality steel swivel wheels with high resistance rubber that allows an incredibly smooth manoeuvrability on any surface.
  • The TTS56-A is a high power, high output active subwoofer system that sets a new standard in the touring sound reinforcement in terms of control, sound quality and power output per size. The new 21" neodymium design represents the result of many years dedicated in pioneering new solutions for the transducers technology. The integration of the 6800 W, two channel digital amplification and the advanced digital processing set a new standard for distortion, noise and thermal efficiency.

Set up and configuration

  • The TTS56-A active subwoofer can be configured both from the rear panel and from remote through the RDNet connection.

Input Sensitivity

  • This rotary switch controls the overall signal level at the input to the power amplifier.

XLow Cut 30/45 Hz

  • This switch provides a high pass 24 dB/octave filtering at 30 or 45 Hz. This setting is perfect for indoor situations or when all the power shall be used in the 45 Hz - 100 Hz range.

XOver 60/90 Hz

  • It provides either a 24 dB/octave low-pass filtering at 80 Hz or 110 Hz. The same crossover frequency in high pass is available from Xover Output Xlr.

Pressing this switch is possible to by-pass the RDNet user setting preloaded on the module. When the RDNet controller is not connected, the by-pass switch act as follow:

  •  By-Pass Switch pressed (LED on), the system bypass the input board and reads the last RDNet setting configuration saved;
  •  By-Pass Switch released (LED off), the system reads the input board and by-pass the user setting eventually loaded on the speaker.

RDNet Configuration

The TTS56-A is equipped with a RDNet connection on board.
By using the RDNet Controller Unit is possible to:

  •  receive status information from the system (amplifiers status, signal levels, system settings, etc)
  •   send commands to the system (mute, solo, change sensitivity, change setting, set user equalization, etc)

Cardioid Set-Up

  • To reduce back and side emission subwoofers cardioid configurations can be useful. The TTS56-A allows creating cardioid systems using groups of three stacked modules. Two modules must point in forward direction with the cardioid switch released. The central module must fire backward with the cardioid switch pressed.
  • It is important that all three modules have the same settings (system delay, sensitivity, x-low cut, xover, etc).

The integrated processing and the cabling reduction will make the set-up faster and easier and, thanks to its compact size, the truck space requirement is reduced to the minimum.

FULLY INTEGRATED SYSTEM

The integrated processing and the cabling reduction will make the set-up faster and easier.
The compactness and lightweight of the system combined with top of class steel on board mechanics helps during rigging operations as well as during transportation


State of the art digital amplifiers

Four independent digital amplifiers, 1000 + 1000 W low frequencies, 1000 W the midrange and 500 W for the high frequency drivers, deliver an astonishing output power of 3500 W per module making the TTL55-A one of the most powerful line arrays module on the market.

PERFECT COOLING

Three fans helps to control internal temperature by driving air through the system cooling it in its critical parts. The electronic processing and the amplifier are housed in a solid aluminium extrusion that helps in thermal dissipation.

POWER FACTOR CORRECTOR

The amplifier is equipped with PFC which regulates the power supply always to operate with the correct voltage. This eliminates any possible dispersion and waste of current, implementing the efficiency of the system in terms of power consumption and energy saving.

DSP control

The TTL55-A represents a state of the art execution of a Dsp controlled multi-way digital amplification.

ENGENIEERED FOR MAXIMUM RELIABILITY

The housing is tightly fitted to the rear of the cabinet and sealed. The power input and all the signal connectors are housed in two recessed and protected panels.

ANALOGUE INPUT BOARD

The analogue input board is fully featured for the set up operations of the module. It offers xlr input and output link, cluster size control switches, high frequencies correction switches, pre-loaded equalizations by-pass switch. Ethercon input and output connect the system in daisy chain on a RDNet monitoring and controlling system from the FOH.

XLR input an output link

XLR input and XLR output for daisy chaining.

Data input and output

Ethercon input and output ports are available for the network input and for the network daisy chain output of RDNet remote monitoring directly from the FOH mixer position.


Low frequencies

The 2 woofers, in a clam shell band-pass loading configuration, provide a very tight and powerful bass response in only 6 Kg weight.
The woofers have been designed with a special low profile to optimize their housing in the cabinet and the size of the overall module.
The acoustical configuration is very efficient in the 100 Hz region and free from dual source cancellations.

The Hyper Ventilation System

The Hyper Ventilation System is the result of a complex combination of holes in the voice coil former, in the magnetic structure and in the woofer basket. In fact, thanks to the large excursion of the cone, the great amount of air generated is directed through the holes creating a very high level of turbulence that keeps the transducer cooler without using a forced ventilation system.

Double nomex layer

Thanks to the amazing strength of the voice coil former, obtained with the double Nomex layer, RCF engineers were able to make bigger holes without compromising the structure stiffness and therefore allowing the passage of a greater quantity of air, which would have not been possible with standard formers.

Silicon surround structure

The surround structure is made of silicon which is the only material able to maintain the memory of its shape. This particular structure guarantees the perfect efficiency of the suspension even after a long period of extensive use.


Midrange

Thanks to the state of the art neodymium 10" midrange design with sealed aluminium basket, the TTL55-A delivers the best vocal clarity from a large format line array module.

Impedance control coil technology

The superior midrange quality and definition is achieved through the exclusive Impedance Control Coil (ICC) technology: a secondary coil wound on the speaker yoke and driven in opposite phase to the primary coil that has the function of cancelling the primary coil inductance, increasing the speaker sensitivity and reducing the speaker distortion.
A primary effect of this technology is the perfection of the temporal behaviour of the speaker, improving the crossover transition and resulting in incredible midrange accuracy and perfect phase linearity.

Special 3.5" voice coil

The transducer is equipped with a special 3.5" voice coil to maximize output and is loaded on a 4-slot constant directivity horn that guarantees a uniform vertical coupling module to module.


High frequencies

The TTL55-A is the only line array module offering the advantages of a straight HF horn and the density of three 2.5".
The new high power neodymium compression drivers feature precision assembled titanium domes and polyester surround and are housed on a very compact 7° waveguide that ensure the maximum wave coherency, very high output power and extreme clarity.

The best sound clarity and coherence available

Thanks to this specific design combined with state of the art transducers design, the TTL55-A guarantees the best sound clarity and coherence available, compared with arrays equipped with complex waveguides that result in too much sound diffraction making the FOH engineer's job a lot harder.


Cabinet

The TTL55-A cabinet is carefully engineered to pack the maximum output and superb sound quality in the minimum available size.

Water resistant Baltic birch plywood

The cabinet is made in high quality Baltic Birch plywood with every layer glued with a special adhesive that makes the cabinet completely water resistant even before the painting process.

HEAVY DUTY POLYUREA PAINT

The paint department inside our factory in Italy utilizes a special polyurea paint to create a very thick full coating of the cabinet making it highly resistant to scratches and bumps.

HEAVILY BRACED INERNAL STRUCTURE

The internal structure of is heavily braced to survive long term use and transportation and all the parts are assembled on metal inserts with metric screws.
The amplifier is housed in a separate chamber from the transducers to offer the best efficiency and reliability.

FRONT GRILLE

The heavy duty front grille is power coated. A special transparent-to-sound foam backing on the inside of the grille helps to further protect the transducers from dust.

HANDLES

The TTL55-A cabinet features two newly designed die-cast aluminium side handles powder coated and with rubber hand-grip. Thanks to the internal scoop design it is possible to use the handle in three different directions to facilitate the transport, positioning and loading operations.

STATE OF THE ART MECHANICS

All the mechanical structure is built in high strength structural Swedish steel.
This special steel by a quenching and tempering process guarantees a yielding strength almost 4 times higher compared to commercial grade steel and maintains the mechanical properties down to -40° C. Thanks to this material the mechanics have high safety factor with a weight under control.

FLEXIBLE AND PRECISE RIGGING SYSTEM

The rigging system is recessed and features 8 possible splay angles, from 0° to 7° with 1° step increment to create curved spiral arrays with very high precision.

TRANSPORTING SUCH A HUGE POWER HAS NEVER BEEN SO EASY

With a very small size compared to the SPL output, the TTL55-A is easily transportable as a single module on a dolly, thanks to the 2 locking points on the front or in groups of four in dedicated karts.


DSP PROCESSING

The integrated digital processor is based on a state of the art 32 bit, floating point DSP running at 96 kHz sampling rate. The calculation capacity largely exceed the processing needs and the DSP is never pushed to the limit.
The DSP takes care of the crossover, the equalisation of the transducers, limiter and system presets such as high pass filters, air absorption and cluster size corrections.

It is possible to operate directly on the DSP from the input board through these switches:

Cluster size control switches

The combination of the 2 central switches gives 4 possibilities of mid low frequencies correction depending on cluster size:

  • 4-6 modules (small flown systems)
  • 7-9 modules (medium flown systems)
  • 10-12 modules (medium large flown systems)
  • 13-20 modules (large flown systems

High frequencies correction switches

The combination of the 2 top switches gives 4 possibilities of high frequencies correction depending on target distance (air absorption correction):

  • near field ( up to 25 meters)
  • mid field ( from 25 to 40 meters)
  • mid/far field ( from 40 to 60 meters)
  • far field ( more than 60 meters)

Pre-loaded equalizations and by-pass switch

This switch by-pass (reset) the last preset loaded on TTL55A DSP with the RDNet Control 8 remote control to allow the manual configuration of the system.

RELIABILITY AND FLEXIBILITY

The RDNet protocol represents a perfect blend of reliability and flexibility, in fact it is based on the RS-485 communication protocol, which is very stable and allows to send and receive data on a simple XLR cable in case Ethercon cables are not available.

REAL TIME CONFIGURATION THROUGH THE EXCLUSIVE RDNet PROTOCOL

The TTL55-A is equipped with a dedicated networking board. Using our proprietary RDNet protocol is possible to monitor all the system parameters, from the input to the status of each single amplifier.

Thanks to the DSP on board of each cabinet, it is possible to address to single cabinets or group of cabinets specific presets or modifications of parameters like gain, equalization or delay in real time.

RCF SHAPE DESIGNER SOFTWARE

In order to assist with the set up procedures for the TTL55-A line array system, RCF has developed a complete prediction software package.

The software enables a complete two dimensional simulation of the behaviour of the TTL55-A modules and also suggest the correct subwoofer combination.

The system curvature angles and the sound projection data are computed with maximum sound pressure levels for the given design.

The software will allow simulations up to a maximum of twenty TTL55-A systems.

The rigging menu provides data for weight, centre of gravity and length of the array configuration. Rigging points and rigging hardware configurations are also computed.
