Product description The TTL55-A MK2 3-Way Active Line Array Module from RCF is a powered 3-way line array designed for touring sound reinforcement in large venues such as stadiums, arenas, and concert halls. It is capable of producing up to 3500W RMS and up to 143 dB SPL and features three 1.5” compression drivers, a 10” midrange driver, and dual 12” woofers with neodymium magnets.
The midrange transducer features an Impedance Control Coil technology. A secondary coil wound on the speaker yoke and driven in opposite phase to the primary coil has the function of cancelling the primary coil inductance, increasing the speaker sensitivity and reducing the speaker distortion. It improves the crossover transition from the midrange to the compression drivers. The integration of four channel digital amplification and the advanced digital processing set a new standard for distortion, noise, and thermal efficiency.
The amplifier represents a DSP controlled multiway digital amplification. The analog input board 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 an RDNet monitoring and controlling system from the FOH. The signal processor is a 32-bit floating point DSP running at 96 kHz. The DSP takes care of crossovers, equalizations, soft limiters, RMS limiters, large signals compression, and customized presets for the 4-way amplification.
The array is equipped with a networking board. Using the proprietary RDNet protocol is possible to monitor all the system parameters, form the input to the status of each single amplifier. Having a DSP on board of each cabinet, it is possible to address to single cabinets or groups of cabinets specific presets or modifications of parameters like gain, equalization, or delay. The RDNet protocol is based on RS-485 communication protocol, it is very stable and it is possible to send and receive data on a simple XLR cable.
The cabinet is built in Baltic birch plywood and protected with heavy duty coating. The internal structure is braced and reinforced and all the parts are assembled on metal inserts with metric screws. With a very small size compared to the SPL output it is easily transportable as a single module on a dolly or in groups of four in carts. The front grille is powder coated and special foam backing very transparent to the sound. The suspension system is designed to have a safety factor 7 up to 20 speakers per side. - Six high power neodymium transducers
- High quality analog input board
- 96 kHz, 32-bit DSP processing
- Remote monitoring and control
- Applications: Touring sound reinforcement for large-sized venues, high quality reinforcement of music and speech, stadiums, arenas, concert halls
