RCF TTS56-A Specifications

TTS56-A

ACTIVE HIGH POWER SUBWOOFER

DESCRIPTION

The TTS56-a is a high power, high output active subwoofer system that sets a
new standard in the touring sound reinforcement. The new 21” neodymium
design represent the result of many years dedicated in pioneering new
solutions for the transducers technology. The integration of
the 6800 Watt , 2 channel digital amplification and the advanced digital
processing set a new standard for distortion, noise and thermal efficiency.
The TTS56-A amplifier section features 2 x 3400 Watt highly advanced digital
amplifier modules. The power amplifiers and
the input board are housed on a heavy duty aluminum paned suspended
from the main cabinet with flexible mounts to obtain the best insulation from
vibrations of the electronic parts.
Each module features Power Factor Correction (PFC), Separated power supply
and amplification, High efficiency, very low consumption, two “on board”
ventilation fans and comprehensive, smart protection features: thermal, over­current, non audio signals.
The TTS56-A is equipped with a dedicated RDnet networking board. It is
possible to monitor all the system parameters, form the input to the status
of each amplifier, to address to single cabinets or groups of cabinets specific
presets or modifications of parameters like gain, equalisation or delay.
It’s possible to create subwoofer cadioid systems using groups of three
modules.
The TTS56-A cabinet is built in Baltic birch plywood and protected with heavy­duty coating. The internal structure is braced and reinforced and all the parts
are assembled on metal inserts with metric screws. The front grille is powder
coated a features and special foam backing very transparent to the sound.
