THE HIGHEST POWER EVER PACKED INTO A SUB

Thanks to the two 3400 W each power amplifiers the TTS56-A delivers the maximum output power per size available on the market today. The amplifiers are equipped with Power Factor Correction (PFC) designed to offer a full voltage supply from any type of plug available.

TWO SEPRATED CHANNELS

Two separate channels with independent power supplies have been provided to ensure top efficiency levels and maximum reliability for an extensive use of the subwoofer during tours.

 
dsp

32 BIT FLOATING POINT DSP

The amplifier integrates a 32 bit floating point DSP controlled through RCF unique RDNet Protocol that manages crossover, equalization, time alignment and protections. 
The state of the art compressor/limiter circuit on board prevents amplifiers from clipping and avoid overdriving the transducers.

ULTRA LOW NOISE

Ultra low noise AD converters ensure the perfect sound quality at the high output required for large events.

 
6 fans

6 FANS

6 fans and a large sized vented aluminium rear panel assure the optimal thermal dissipation.
The amplifier is housed on a unique Vibrostop floating aluminium panel for extra protection during transportation.

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

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

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.

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

INPUT SENSITIVITY

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

 
xlow cut

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

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.

 
time delay encoder

TIME DELAY ENCODER

Provides a time delay setting expressed in meters.

 
delay display

TIME DELAY DISPLAY

High quality digital display that shows the time delay setting.

 
status indicators

4 SYSTEM STATUS INDICATORS

Power, status, signal and limiter.

 
cardioid setup

CARDIOID SET UP

This switch provides a special equalization and delay setting to create a cardioid pattern when the system is used in conjunction with two other TTS56-A modules.

 
link and active leds

LINK AND ACTIVE LEDS

Indicate when the module is addressed and configured from the RDNet controller.

 
rdnet bypass

RDNET BYPASS

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

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).
