TTL55-A

ACTIVE THREE-WAY LINE ARRAY MODULE

 

The TTL55-A is a high power, three way, active line array module engineered to deliver an incredible output for use in indoor or outdoor large spaces. The system is designed to be easily scalable from few modules for medium and small theatres to full size arrays for very large outdoor stadia and public spaces.

 

The three new designs for the six neodymium transducers that power the system represent the result of many years dedicated in pioneering new solutions using the best materials available on the market. The integration of the 3500 W four channel digital amplification and the advanced digital processing set a new standard for distortion, noise and thermal efficiency.

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.

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

 

 
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.

 

 
hyper ventilation system

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

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

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

 

 
silicon surround structure

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.

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:

 
dsp

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

 
dsp

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.

 
rdnet

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.
